Abstract
Description
Technical Field
[0001] This invention relates to the field of wastewater treatment technology, specifically to a modular construction method for an AAO wastewater treatment pond aquatic ecological biofilm reactor. Background Technology
[0002] The AAO (anaerobic-anoxic-aerobic) process is widely used in urban wastewater treatment projects due to its biological nitrogen and phosphorus removal capabilities. To shorten the construction cycle and adapt to the needs of renovation and expansion, the industry is gradually adopting prefabricated or modular assembly methods to construct AAO tanks and superimpose biofilm reactor units, such as MBBR suspended carriers, IFAS mud-film composites, or fixed packing biofilm units, thereby improving the stability and shock resistance of nitrification and denitrification within a limited tank volume. For example, the published invention patent application CN114604965B discloses an AAO and AAO dual-mode wastewater biochemical system and its operation method based on MBBR, which mainly achieves nitrogen removal through the arrangement of reaction sections and the switching of operation modes. In addition, the published invention patent application CN105439281B discloses a moving bed biofilm reactor, which mainly improves the reaction effect through the configuration of internal flow guiding components and aeration structures. However, the aforementioned existing technologies are mostly designed for the internal structure of process sections or individual biofilm reactors, making it difficult to solve the key engineering challenges of modular assembly applications. At module connection points such as tank module interfaces, partition wall flow guide components, flow outlets, and weirs, assembly tolerances accumulate and accumulate. Furthermore, differences in sealing structures and construction conditions can easily lead to hidden hydraulic deviations after commissioning, such as short-circuiting, cross-flow, backflow short-circuiting, and localized dead zones between anaerobic, anoxic, and aerobic zones. This causes the effective residence time, backflow ratio, and dissolved oxygen diffusion boundary of each zone to deviate from the design parameters. Under normal operating conditions, the nitrogen and phosphorus removal effects are unpredictable and prone to phased failures due to load fluctuations and start-up / shutdown cycles. Furthermore, existing technologies lack rapid verification and location of zonal hydraulic equivalence and boundary integrity for modular delivery scenarios. Problems cannot be traced back to modules and specific interfaces, requiring shutdown, disassembly, and rework for rectification, leading to project delays and significant increases in operation and maintenance costs. Therefore, it is necessary to propose rapid verification and location technologies and module-level correction technologies suitable for modular construction and the initial commissioning phase, in order to achieve controllable zonal boundaries, verifiable hydraulic distribution, and stable effluent compliance. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this invention provides a modular construction method for AAO wastewater treatment pond aquatic ecological biofilm reactors, which solves the problems of traditional methods lacking rapid verification, positioning, and module-level correction for zonal hydraulic equivalence and boundary integrity.
[0004] To achieve the above objectives, the present invention provides the following technical solution: AAO wastewater treatment pond aquatic biofilm reactor modular construction method, including: S1: Establish module ledgers and interface lists, determine the zoning boundary diameter, weir elevation, return flow settings, measurement point layout, and verification time window; S2: Assemble each module according to the baseline, close the interface in sequence and pre-tighten in stages, complete the alignment and retesting of the partition wall diversion and the overflow weir, and write the initial valve position and the position of the adjustable component. S3: Fill water in stages according to the preset water level and maintain steady pressure, check the sealing status of the interface and the structural posture, and update the interface status record; S4: Perform zonal hydraulic equivalence and boundary integrity verification under preset disturbance conditions, collect measurement point response data and determine boundary number and interface number according to anomaly criteria; S5: Perform module-level reversible correction based on the number, adjust the overcurrent limiting, flow guiding components, weir components, return inlet components and gas supply distribution components, complete the review and update the ledger and verification plan.
[0005] Furthermore, establish a module ledger and interface list, determine the zoning boundary diameter, weir elevation, return flow settings, measuring point layout, and verification time window, including: Receive project delivery data packets and establish module numbering rules with version and number mapping and interface numbering rules with interface direction codes; Establish a module ledger and interface list, associate boundary standards with the list table, and determine the zoning boundary standards, weir elevation, return flow settings, measurement point layout, and verification time window; Generate a state machine verification task sheet with access control and write-back of handling procedures, forming a ledger baseline package.
[0006] Furthermore, the modules are assembled in place according to the baseline, including: When assembling each module according to the baseline, verify the closed record of the bottom elevation baseline of the pool, the axis baseline of the pool body and the boundary baseline of the zone; Each module is set with at least two positioning control points and its positioning posture is adjusted by support pads to complete the positioning retest. When the on-site retest exceeds the allowable deviation of the interface list or boundary caliber from the list, relocation or isolation measures should be implemented, and the measures number should be recorded in the ledger.
[0007] Further, the interfaces are closed sequentially and pre-tightened in stages, the alignment of the partition wall guide and the overflow weir is re-measured, and the initial valve position and adjustable component position are recorded, including: When closing the interface sequentially and pre-tightening in stages, verify the batch of sealing material and the cleanliness of the interface, advance the pre-tightening according to the predetermined loading level, and re-measure the misalignment and elevation difference after each level of pre-tightening and write back the record. Complete the alignment and retesting of the partition wall diversion and the overflow weir, perform correction according to the systematic deviation judgment rules, and record the valve opening and the initial position of the adjustable components.
[0008] Furthermore, water is added in stages according to preset water levels and maintained at steady pressure, including: When filling water at preset water levels and maintaining steady pressure, a wet task sheet is generated based on the verification task sheet, setting the water level level, target water level ratio, upper limit of filling rate, allowable fluctuation zone, steady state window and recording frequency. The steady-state determination rule is set as follows: the water level changes recorded in multiple consecutive records all fall within the allowable fluctuation range, and the water level changes in adjacent records do not increase.
[0009] Further, check the interface sealing status and structural orientation, and update the interface status record, including: When checking the sealing status and structural posture of the interface and updating the interface status record, determine the observation point and observation window length according to the interface number and classify the leakage. When the leakage level is dripping, perform additional pre-tightening and retest; When the leakage level is linear flow, the leakage interface and adjacent interfaces are partially disassembled and inspected, and steady-state pressure maintenance is carried out again at the corresponding water level. According to the module benchmark point, the attitude is retested. When the attitude index exceeds the limit, it will revert to the next higher water level, and the leakage classification, handling action and emergency drainage trigger information will be written into the interface status table.
[0010] Furthermore, under preset disturbance conditions, zonal hydraulic equivalence and boundary integrity checks are performed, including: When performing zone hydraulic equivalence and boundary integrity verification under preset disturbance conditions, the verification task sheet is version-linked with the wet pressure holding qualified package and the measuring point layout table; Select flow pulse disturbance, water level micro-disturbance, or backflow disturbance in the task list and fix the execution order; Set the pre-check items and interruption conditions in the task sheet, and write the values of nominal dwell time and nominal flow rate.
[0011] Furthermore, the response data of the measurement points are collected, and the boundary number and interface number are determined according to the anomaly criteria, including: When collecting measurement point response data and determining boundary and interface numbers according to anomaly criteria, set the baseline window and sampling window; The entries for early, late, dispersed, and infiltration anomalies are determined based on the main change caliber and the wake caliber. A candidate set of interfaces is generated and sorted based on the mapping from measurement points to boundaries and the mapping from boundaries to interfaces. Write back the exception type code and confirmation flag in the interface list and boundary list.
[0012] Furthermore, based on the number, module-level reversible correction is performed, including: When performing module-level reversible correction based on the number, a correction task sheet is generated based on the confirmed boundary number and interface number; Each correction only adjusts one control point and generates a corresponding review task; When a target entry is in a pending review state or a control point lacks a reset method field, the correction for that entry is blocked. The state machine is used to write back the status of the correction record and the review record.
[0013] Furthermore, adjustments were made to the flow restriction, flow guiding components, weir components, return inlet components, and gas supply distribution components. The review and updating of the ledger and verification plan were completed, including: When adjusting the overflow limiting components, flow guiding components, weir components, return inlet components, and air supply distribution components, the adjustment amount is constrained by the allowable range of the components, the allowable alignment band, and the valve position reference band. The parameters of the task sheet that triggered the exception were reviewed and reused. When the review is approved, the component location is marked with a lock tag, and the ledger and review plan are updated simultaneously.
[0014] Compared with existing technologies, this invention provides a modular construction method for AAO wastewater treatment pond aquatic ecological biofilm reactor, which has the following beneficial effects: 1. This invention establishes a module ledger and interface list, using version numbers to solidify the zoning boundary diameter, allowable weir elevation zone, backflow reference zone, and the mapping relationship from measuring points to the boundary. Controlled in-situ assembly, graded pre-tightening of interfaces, and alignment and re-measurement of the diversion weir of the partition wall form a traceable construction baseline. Water is filled and pressurized in stages according to a preset water level ratio, and interface leakage levels and structural posture changes are graded and judged. Handling and re-measurement are written back according to interface number and module number. The response time sequence of measuring points under preset disturbance conditions is collected. Based on anomaly criteria such as early, late, dispersed, and seepage, two layers of mapping from measuring points to the boundary and from the boundary to the interface are superimposed to generate boundary number and interface number. Single-control point reversible correction and same-diameter verification are performed according to the number, updating the ledger and verification plan. This achieves controllable zoning boundaries, verifiable hydraulic distribution, locatable and closed-loop problems, and stable effluent compliance, thus solving the problem of traditional methods lacking rapid verification, location, and module-level correction for zoning hydraulic equivalence and boundary integrity.
[0015] 2. This invention integrates modular assembly, tolerance control, watertightness verification, hydraulic calibration, and corrective verification into a single numbering and version specification. It maps zoning boundaries, interface status, component locations, and measurement data, enabling seamless material batch verification, geometric re-measurement, wet-state treatment, disturbance interpretation, and corrective verification within the same task sheet and record chain. In cases of leakage, attitude drift, or abnormal hydraulic response, component numbers, threshold reference versions, and historical treatment entries can be associated with boundary and interface numbers, enabling interruption continuation, responsibility tracing, and reset / rollback. This reduces repetitive disassembly and assembly and lack of verifiability caused by experience-based trial and error, achieving unified construction delivery standards, verifiable quality judgment, reproducible positioning and correction, and sustainable commissioning verification. Attached Figure Description
[0016] Figure 1 This is a schematic diagram of the modular construction method for the AAO wastewater treatment pond aquatic ecological biofilm reactor of the present invention. Detailed Implementation
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Example 1: Figure 1 A modular construction method for the AAO wastewater treatment pond aquatic ecological biofilm reactor is presented, including: S1: Establish a module ledger and interface list, determine the partition boundary diameter, weir elevation, return flow setting, measuring point layout, and verification time window. Specific implementation details are as follows: Before delivery, a standardized and traceable baseline should be established for the modular anaerobic-anoxic-aerobic wastewater treatment tank. This baseline serves as an index input for the next steps: module placement and assembly, interface closure and pre-tightening, wet pressure holding, hydraulic equivalence verification, boundary integrity verification, and module-level correction. Before construction, a project delivery data package should be received. This package should be stored in a structured directory with accompanying metadata. The directory should include at least the design deliverables, prefabricated factory inspection reports, delivery inventory lists, construction measurement benchmark documents, zoning operation control index documents, and site measurement point layout sketches. The metadata should include at least the document source, generation time, responsible person, scope of application, and consistency verification conclusions. Establish a numbering rule and write it into the version field; the partition code takes a single-character encoding, where the anaerobic zone is "厌", the anoxic zone is "缺", the aerobic zone is "好", and the return channel zone is "回"; the module number consists of the partition code plus 2 or 3 digits, and the digits increase sequentially according to the installation order. For example, the first module in the anaerobic zone is recorded as 厌01, the second module in the anoxic zone is recorded as 缺02, and the third module in the aerobic zone is recorded as 好03; the interface number is formed by splicing the numbers of two adjacent modules and appending an interface direction code. The interface direction code is used to identify the orientation of the interface relative to the hydraulic path and can be selected from values such as upstream, downstream, left, right, etc., to ensure consistency in on-site identification,复测记录 (re-measurement record), and positioning reference; the numbering rule is frozen after release, and when adjustments are required due to design changes, a version upgrade is performed and a number mapping table is generated; the number mapping table at least includes fields such as the old number, new number, reason for change, effective version, associated record guide, etc., for historical traceability and difference verification. The verification and correction of the current version are based on the upgraded numbering rule; Subsequently, establish a module ledger with the module number as the unique index. The module ledger is in tabular form and at least includes fields such as module type, prefabrication batch, arrival batch, partition attribution, design water level line, coordinates of key structure reference points, set of interface numbers, list of embedded parts, list of adjustable components, list of carrier restraint components, status field, responsibility field, etc.; the module type is used to distinguish between pool wall modules, pool bottom modules, partition wall modules, diversion modules, overflow weir mouth modules, and return channel modules, and is referenced for subsequent lifting order, re-measurement items, acceptance criteria, etc.; the prefabrication batch and arrival batch have an associated relationship, and the association basis is the prefabrication factory inspection form and arrival inventory list, with key records such as batch number, batch quantity, appearance inspection conclusion, and defect record number, etc.; the coordinates of key structure reference points are construction measurement reference documents, and the reference points are module interface corner points, weir mouth control points, and partition wall reference holes, recorded using a unified coordinate system and accompanied by the measurement date, measurement personnel, and measurement tool number for convenient alignment re-measurement and attitude drift traceability; the set of interface numbers solidifies the module association relationship and is used as part of the positioning index key. The set of interface numbers is consistent with the interface list to avoid multiple references to the same interface; An interface list is established using the interface number as the primary key. The list must include at least the following fields: interface type, sealing structure type, sealing material batch, allowable geometric deviation of the interface diameter, target pre-tightening diameter, pre-tightening loading level, re-testing points, leakage observation points, and treatment records. The interface type can be selected as a planar butt joint, corner joint, weir connection, or through-wall joint, used for subsequent pre-tightening strategies and re-testing density references. The sealing material batch is linked to the module prefabrication batch for consistency verification and traceability. The sealing structure type must at least distinguish between rubber seals and elastic adhesive seals. The allowable geometric deviation of the interface diameter is specified using a re-measurable method. The flatness deviation is set at no more than 2 mm per meter, the elevation difference is set at no more than 3 mm between the reference points at both ends of the interface, and the misalignment is set at a maximum value of no more than 2 mm at the interface edge. All these values are matched with the compensable amount of the allowable compressible thickness or compressibility rate of the sealing material to clarify the boundaries for handling exceeding limits. Re-testing points are pre-marked in the list, with flatness along... The interface surface should be measured along at least two measuring lines, and the maximum deviation should be recorded. The elevation difference should be measured at the two reference points at both ends, and the difference should be recorded. The misalignment should be measured at at least three measuring points along the interface edge, and the maximum value should be recorded. The positions of the measuring lines and measuring points should be described by coordinates or relative endpoint distances to ensure consistent and traceable measurement calibers. The pre-tightening target caliber should be expressed by compression ratio or compression thickness. The compression ratio of rubber seals should be 10% to 20%, and the compression amount of elastic seals should be 1 to 3 mm. The pre-tightening loading level can be selected as 3 or 4 levels, with loading ratios of 30%, 60%, and 100% respectively, or 30%, 60%, 90%, and 100%. The values are based on the rebound and creep characteristics of the sealing material and the need for on-site graded pre-tightening to reduce the risk of misalignment amplification and extrusion. Leakage observation points should be arranged according to the interface type and marked with coordinates or relative distances for a unified caliber for subsequent watertightness observation. The treatment record is used to register the treatment action number and effective version for replacement, repair, and recertification, ensuring the traceability of interface status and treatment process. To transform zoning boundaries into acceptable and locatable objects, a boundary specification and list table are established and linked to the ledger. The boundary specification and list table should include at least the following fields: boundary number, associated zoning zone, boundary component number, flow outlet number, weir number, allowable boundary misalignment, allowable boundary elevation difference, allowable boundary bypass opening, boundary dissolved oxygen difference threshold, allowable weir elevation zone, backflow valve position reference zone, allowable backflow disturbance range, and verification elements. Allowable boundary misalignment can be no greater than 2 mm, and allowable boundary elevation difference no greater than 3 mm, used to constrain the risk of bypass openings caused by geometric discontinuities across module boundaries. Weir elevation can be frozen according to the design reference elevation, for example, the design weir elevation ±3 mm, and consistent with the minimum single adjustment amount of the adjustable weir plate, facilitating subsequent reversible fine-tuning. The boundary dissolved oxygen difference threshold is used for boundary integrity verification, such as between anaerobic and anoxic boundaries. The boundary difference is no less than 0.5 mg / L, and the difference between the hypoxic and aerobic boundary is no less than 1.0 mg / L. The values are based on the target window difference given in the zonal operation control index document and the judgment requirement that can still be distinguished under instrument error. To ensure the reliability of the threshold judgment, the instrument consistency caliber is fixed in the verification elements. Before verification, the zero point and span are checked according to the unified calibration process. The allowable deviation is, for example, ±0.2 mg / L. The calibration record number and calibration date are written into the boundary caliber and list table. The reflux setting is frozen in this table as the reflux valve position reference zone and the reflux disturbance allowable range. The reflux disturbance allowable range is, for example, a valve opening change of 10% to 20% and kept within the valve position reference zone. The reflux ratio target zone is referenced from the zonal operation control index document as the input caliber for the subsequent verification task sheet. It is not used as an independent judgment item for construction acceptance, so that the boundary between the construction delivery caliber and the operation setting caliber is clear. The measurement point layout serves as the input for the positioning closed loop and is fixed as such. The measurement point layout should include fields such as measurement point number, measurement point type, assigned zone or boundary, installation location, sampling frequency, data record, boundary number mapping, and calibration record number. Each zone should have no fewer than three response measurement points, with two dissolved oxygen measurement points on each side of the key boundary, two flow measurement points on each return path, and gas supply distribution measurement points on the main gas supply line and at least two branch lines. Measurement point locations are expressed as coordinates or distances relative to structural reference points, referencing the construction survey reference documents and the boundary caliber and list of reference point coordinates. On-site installation and re-measurement are possible. The sampling frequency can be referenced in the later verification task sheet, taking several intervals from 10 to 60 seconds, based on the response acquisition time resolution requirements in the zone operation control index document and the refresh cycle of the on-site instruments. Data recording is done locally, manually reviewed and signed, referencing the record caliber of the verification task sheet. The boundary number mapping field is associated with the boundary caliber and list of reference points. In case of anomalies, adjacent measurement point sets can be directly located by boundary number, facilitating subsequent verification and correction. Numbering rules, ledgers, lists, and caliber tables generate verification task sheets. A state machine is used to solidify the delivery process and access control table. The state machine is configured for preparation, assembly, interface closure, dry verification, wet pressure testing, hydraulic verification, boundary verification, correction, review, and delivery. Entry and exit conditions are set for different states, with entry and exit decisions derived from record items and status fields in the ledger baseline package, respectively. The access control table should at least include fields such as gate control items, decision sources, trigger actions, write-back fields, and unlocking conditions. Gate control items include material consistency anomalies, prefabrication batches, missing key benchmark coordinates, and inconsistent connection relationships. Issues include missing critical boundary numbers, excessive instrument consistency, and insufficient measurement point coverage; the source of judgment refers to fields or record items in the baseline package of the ledger; the trigger action is to generate a disposal number, set the object status to pause, write the disposal number back to the corresponding form disposal record field and simultaneously write back the effective version; the unlock condition is to complete the correction and pass the review, and write back the effective version, so that the defect handling is traceable and auditable within the same closed loop; the threshold and range judgment caliber refers to the frozen numerical caliber and allowable range in the design deliverables, prefabricated inspection forms, measurement benchmark documents, operation control index documents, and instrument calibration records; After the baseline package is generated, it will be used for reference in the subsequent assembly process. The baseline package should include at least the following documents: module ledger snapshot, interface list snapshot, boundary caliber and list table snapshot, measurement point layout table, and verification task sheet. Each document should include a version number, generation time, and responsibility information, and correspond to the project delivery data package. The filing work should be carried out according to the on-site resource allocation. Based on the feasible production capacity of on-site measurement and recording and the organizational requirements of not forming a construction bottleneck, the number of measurement personnel should be 2 and the number of recording personnel should be 2. The number of filings per day should not be less than 40, and the module and interface status fields should be updated to "to be assembled" and "to be closed".
[0019] S2: Assemble each module according to the baseline, close the interfaces sequentially and pre-tighten in stages, complete the alignment and re-measurement of the partition wall diversion and the overflow weir, and write the initial valve position and adjustable component position. The specific implementation is as follows: Input the baseline package of the ledger and the on-site baseline result file; the baseline package of the ledger should at least freeze the fields such as module number, interface number, boundary number, component number and version number, and the on-site baseline result file should at least contain the pool bottom elevation baseline, the longitudinal and transverse axis baseline of the pool, the coordinate result of the partition boundary baseline and the closure record, etc.; the module arrival retest table, interface hierarchical pre-tightening record, alignment retest table and component position table should all write back the consistent version number and responsibility information as the index key, and write back the handling number and status field after an anomaly occurs, retest according to the corresponding form and write back the result, and close the loop record; At the start of construction, the baseline for the bottom elevation of the pool, the baselines for the longitudinal and transverse axes of the pool body, and the baselines for the boundaries of the zones were checked and closed. The check was conducted using a network of the same control points. The closure error was set to no more than 5 mm per 100 meters. This threshold was determined with reference to the control network accuracy level and closure record caliber in the baseline results document, and in combination with the interface misalignment control caliber and the sensitivity of the allowable elevation zone of the weir to the baseline error. The closure error was determined based on the fields in the closure record. The closure record must include at least the fields for plane closure error, elevation closure error, measurement method, instrument model, and tool number. The larger of the plane closure error and the elevation closure error was used for determination. After the check was passed, the target coordinates of each module were written into the target field of the module ledger and a hoisting sequence table was generated. The hoisting sequence table followed the rules of internal to external, downstream to upstream, and internal to boundary of zones. Symmetrical placement was adopted for key modules in the same zone to reserve operational space for the re-measurement of the alignment between the partition wall and the weir. The module placement adopts the rule of positioning first and then sitting down; during the positioning stage, positioning control points are set near the intersection of the bottom elevation baseline and the pool axis baseline. Each module has no less than 2 positioning control points, which are preferentially arranged at the interface corners or the corresponding positions of the partition wall reference holes. The selection of positioning control points is based on meeting the requirements of re-measurement and avoiding rotational deviation caused by single-point positioning. Before the module is seated, adjustable support shims are placed at the four corners or sides. The thickness of the shims is 1 to 10 mm and the adjustment particle size is 1 mm. The shim specifications are the commonly available specifications on site and are matched with the adjustment particle size of the allowable elevation zone of the weir. Each shim is assigned a shim number and the initial thickness value is recorded. The shim number is associated with the module number and serves as the positioning basis for subsequent attitude correction and retraction reset. After the module is deployed, a retest is performed and the module deployment retest form is written back. The module deployment retest form must include fields such as module number, retest time, interface surface geometric retest results, partition boundary line offset, retest tool number, and retest personnel. The retest measuring tools can be laser level, steel ruler, feeler gauge, or equivalent precision measuring tools. The measuring tool number is written into the retest tool number field. The threshold and value rules for interface surface geometry re-measurement; the allowable deviation of interface geometry in the interface list; flatness is measured according to the specified survey line in the interface list, and the maximum value is taken; elevation difference is taken according to the difference between the reference points at both ends of the interface, and the maximum value is taken at the specified measurement point along the interface edge for misalignment; the threshold and value rules for the offset of the partition boundary line refer to the boundary caliber and the list table, and the offset measurement point refers to the coordinates of the important structural reference points in the module ledger; If any retest index exceeds the limit, repositioning is initiated. Repositioning prioritizes adjusting the elevation difference and interface posture by adjusting the thickness of the support pads, followed by correcting the boundary line offset by fine-tuning the module's lateral side. After adjustment, the retest is rewritten to form a closed-loop record. The number of repositioning cycles is limited to no more than 2, with the maximum number of cycles matching the single-shift operation window on site. If convergence is still not achieved after exceeding the number of cycles, the remediation options are module replacement or interface surface repair. After remediation, the module re-enters the in-place retest and rewrite process to ensure that the module's in-place state remains stable before interface closure. Interface closure follows the interface list, utilizing a controlled closure sequence and graded pre-tightening to control misalignment caused by pre-tightening. The closure sequence follows the order of inner to outer, low water level to high water level, and internal to boundary of a zone. When multiple interfaces exist within the same zone, symmetrical interfaces are alternately entered into the pre-tightening level to balance the force and reduce the distortion of boundary components caused by local stress concentration. Before interface closure, interface surface cleaning and sealing material verification are completed. Interface surface cleaning is judged by the absence of visible mortar particles, oil stains, and warped attachments, and a cleaning confirmation mark is written into the interface graded pre-tightening record. Sealing material verification is judged by the consistency of the sealing structure type and sealing material batch with the interface list; if inconsistent, the interface status is updated to pending treatment, and a treatment number is written back into the interface list. The graded pre-tightening loading level, the proportion of each level, and the pre-tightening target diameter are set using the interface list freezing method. After each level of pre-tightening is completed... The interface hierarchical pre-tightening record is re-measured and written back for misalignment and elevation difference. The interface hierarchical pre-tightening record should include at least the following fields: interface number, pre-tightening level, pre-tightening value, re-measured misalignment, re-measured elevation difference, re-measurement time, operator, and re-measurement tool number. When the re-measurement shows that the misalignment continues to increase with the pre-tightening and approaches the threshold of the interface list, attitude correction is initiated. Attitude correction is primarily achieved by adjusting the support pads or eccentric pads of adjacent modules to achieve reversible retraction. The adjustment granularity is 1 to 3 millimeters, and the number of rounds is no more than 2. The above granularity and number of rounds are determined by the controllable adjustment capability on site, the allowable constraint of the weir, and the control requirements to avoid attitude drift caused by repeated trial and error. If the interface still does not converge after attitude correction, the handling options may be to disassemble the interface and replace the module or repair the interface surface and then re-close it. Re-closing starts from the first level of pre-tightening and the re-measurement and writing back are repeated to keep the interface pre-tightening record continuous and traceable. After the interface closure and pre-tightening retest are passed, the alignment retest of the partition wall guide and the weir is carried out, and the retest results are written back to the alignment retest table. The alignment retest table should include at least the following fields: boundary number, associated module number, bottom fitting status of the partition wall, top elevation of the partition wall, attitude angle of the guide component, net width of the overflow, top elevation of the weir, verticality of the weir plate, retest tool number, retest personnel, and judgment fields. The top elevation of the weir is judged according to the boundary diameter and the allowable range in the list table. The allowable deviations of the attitude angle of the guide component and the net width of the overflow are, for example, ±2 degrees and ±3 mm, respectively. The deviation range is determined by combining the component installation hole tolerance, the accuracy of on-site measurement, and the sensitivity of the zonal hydraulic distribution to geometric deviations. The judgment rules for systematic deviations are written into the judgment word. When the deviation directions of three adjacent weir measuring points within the same boundary group are consistent and all exceed one-third of the allowable zone of the weir, it is judged as a systematic deviation and enters the weir correction process. Weir correction can be performed by adjusting the elevation of the weir plate and the weir pad, with a correction particle size of 1 to 3 millimeters. The correction particle size is determined in combination with the minimum adjustment amount of the adjustable weir plate and the convergence requirement of the allowable zone. The number of corrections is no more than 3 times, which is determined in combination with the on-site operation window and the controllability of reversible adjustment. After each correction, the weir top elevation and the verticality of the weir plate are remeasured and recorded. If the deviation does not converge after exceeding the number of corrections, the process is transferred to the review of the baseline results and the module placement remeasurement record. Priority is given to checking the baseline error and the placement attitude error before determining whether to expand the correction range. After the alignment and retest are passed, the initial valve positions and adjustable component positions should be recorded. The recorded items should include at least the internal return valve, sludge return valve, aeration branch valve, and components such as adjustable guide vanes, adjustable weirs, flow-limiting vanes, return inlet guide vanes, and air supply equalization vanes. The component position table should be stored in a tabular data structure, including at least the component number, component type, installation location, initial position value, allowable range, adjustment particle size, reset method, associated boundary number, and verification items. The initial valve position value range should reference the boundary diameter and the return valve position reference band and allowable range of components in the list, such as internal return valves. Valve values are set at 30% to 50%, sludge return valve values at 25% to 45%, and aeration branch valve values at 25% to 55%. These values are based on the boundary diameter, the adjustable range fixed in the bill of quantities, and the adjustment margin required for reversible correction on site. This avoids valves being at their limit opening, which would lead to a lack of comparability in subsequent verifications. The initial position of adjustable components is set at the neutral position or the design reference position. The verification items are linked to the wet pressure observation points and the boundary numbers corresponding to the hydraulic verification in the component position table. This allows for location of abnormalities by component number and boundary number, and reversible reversal by resetting the system. The output forms an assembly closure record package, which includes at least the following fields: module arrival retest table, interface graded pre-tightening record, alignment retest table, and component position table. Simultaneously, the status fields of the module ledger and interface list are updated to "closed and awaiting wet state". The on-site organizational constraints are set at 30 to 60 minutes for each interface closure and retest, and 15 to 30 minutes for each weir alignment retest. Each team must be equipped with at least 1 surveyor, 2 assemblers, and 1 recorder, based on the frequency of write-back of graded pre-tightening and alignment retests, on-site measurement and retest time, and construction rhythm control requirements.
[0020] S3: Fill water in stages according to the preset water level and maintain steady pressure, check the interface sealing status and structural posture, and update the interface status record. The specific implementation is as follows: Before the zonal hydraulic equivalence and boundary integrity verification, the modular anaerobic-anoxic-aerobic wastewater treatment tank undergoes wet-state verification. Inputs include an assembly closure record package, an on-site water supply plan, and a drainage emergency plan. The assembly closure record package includes a module ledger, interface list, component location table, alignment verification table, and version number. The on-site water supply plan specifies the available water capacity, water supply fluctuation boundaries, and allowable filling cycle time. The drainage emergency plan specifies the emergency drainage path, valve operation sequence, and safety boundaries. Wet-state verification is performed under wet-state pressure holding conditions as per the verification task sheet, generating a wet-state task sheet as a wet-state configuration record. The wet-state task sheet must at least include water level configuration and target water levels for each level. The threshold parameters include: upper limit of water filling rate, allowable fluctuation range, steady state window, recording frequency, steady state judgment, measurement method, measurement resolution, set of observation points, set of attitude reference points, threshold reference version number, handling branch gating, upper limit of backoff rate, emergency drainage trigger, responsibility information, and timestamp field. The values of the above threshold parameters are referenced from the design water level parameters, water supply plan boundary parameters, and drainage emergency plan safety boundaries, and are related to the boundary caliber in the baseline package of the ledger and the list table, interface list, and module ledger retest caliber. Threshold adjustments are written back through wet task sheet version upgrades, historical versions are retained and the reasons for changes are recorded, and the record chain can be traced and interrupted. After the wet state task sheet is generated, an observation point set is extracted from the interface list, and an attitude reference point set is extracted from the module ledger. The observation point set is indexed by the interface number. Each interface has at least one direct observation point, and boundary-related interfaces have at least one additional close-range observation point. The direct observation point can be selected as an unobstructed observation position outside the interface that can be stably reproduced. The close-range observation point can be selected as an observation position no more than 0.5 meters away from the interface sealing line. This distance range is derived from the accessibility of close-range observation on site and the identifiable requirements for the manifestation of the leakage path. The observation point information in the interface list includes at least the point number and interface number. Fields such as module number, orientation description, distance from the relative interface centerline, point identification method, and reviewer are used to ensure that different work groups repeatedly observe the same location. The attitude reference point set uses the module number as an index, and each partition selects no less than two module top edge reference points and no less than one weir control point. The reference point number is consistent with the coordinates of the key structural reference points in the module ledger. The attitude reference point set fields include at least the reference point number, module number, coordinate reference version number, measurement tool number, measurement personnel, and measurement timestamp, which are used to remeasure settlement, torsion, and weir drift at the same reference point and form a traceable record. The water level configuration is fixed by the wet task sheet. There are at least three water level levels: low, medium, and design. The low and medium water levels are set according to the design water level ratio, for example, 30% to 40% for low, 60% to 70% for medium, and 100% for design. Each target water level is written into the wet task sheet, which includes at least the following fields: water level configuration, target water level for each level, selection instructions, responsibility, and timestamp. The selection instructions use executable rules and are written back synchronously: when there are many boundary-related interfaces or boundary interface handling numbers have a history of not being cleared, the low water level is set to 30% and the medium water level to 60%; when there are few boundary-related interfaces and the alignment retest table shows that the weir top elevation deviation is less than half of the allowable zone at the weir, the low water level is set to 40% and the medium water level to 70%; if the above conditions cannot be met, the intermediate values of 35% for low and 65% for medium are used, and the person confirming the work shift is recorded in the responsibility field. The upper limit of the water filling rate is written into the upper limit of water filling rate field, and the value is, for example, no more than 0.3 meters per hour. When the water supply capacity is insufficient, the rate is not increased, and the water filling time is extended to reach the target water level. The reason for the interruption and the recovery time are recorded in the remarks field of the water level record table to avoid introducing additional disturbances due to sudden changes in the water filling cycle. The water level record table should include at least the following fields: water level level, steady state number, timestamp, measured water level, difference from the target water level, change per unit time, recorder and tool number, and remarks. After reaching the target water level, the system enters a steady-state pressure maintenance phase. The allowable fluctuation range is written into the allowable fluctuation range field, with a value of, for example, ±2 mm per hour. The measurement method field can be selected as a level gauge or a level meter, and the measurement resolution field has a value of, for example, 1 mm or 2 mm. The allowable fluctuation range is not less than twice the measurement resolution and matches the recording frequency, so that it can be determined whether the water level change has entered the allowable range within the same recording interval. The steady-state window is written into the steady-state window field, with a value of, for example, 2 to 6 hours for low water level, 4 to 12 hours for medium water level, and 12 to 24 hours for design water level. The recording frequency is written into the recording frequency field, with a value of 10 to 30 minutes. The above values are derived from the design water level, the controllable fluctuation boundary of the water supply plan, the safety boundary of the drainage emergency plan, and the boundary of the on-site measurement resolution and duty organization. Steady-state determination is written into the steady-state determination field and uses an auditable standard: if the absolute value of the unit time change in three consecutive records after the start of steady-state is less than the allowable fluctuation range, and the unit time change between two adjacent records does not increase, the steady state is determined to be valid; if any condition is not met, the steady-state window is extended and the reason for the extension is marked in the water level record table. During steady-state conditions, two record chains are formed: a water level record sheet and an attitude check sheet. The water level record sheet includes at least the following fields: water level level, steady-state number, timestamp, measured water level, target water level difference, change per unit time, recorder, and tool number. The attitude check sheet includes at least the following fields: module number, benchmark number, top edge elevation change, interface relative misalignment change, wall end gap change, weir top elevation drift, retest time, retester, tool number, and trigger reason. Attitude retests are performed at the start of steady-state, at the midpoint of steady-state, and at the end of steady-state, and can be encrypted after a handling action is completed, with the encryption reason written into the trigger reason field. The attitude-related thresholds do not have separate standards. The interface misalignment change threshold references the allowable deviation standard in the interface list. The weir drift threshold references the boundary standard and the allowable weir zone in the list. The module top edge elevation change threshold references the benchmark re-measurement standard in the module ledger. The threshold reference version number field registers the referenced source file and version number. The wet task sheet can write initial values that are easy to execute on site, such as the module top edge elevation change not exceeding 2 mm, the interface misalignment change not exceeding 1 mm, and the weir top elevation drift not exceeding 2 mm. When the referenced source standard gives a more stringent threshold, the more stringent threshold is executed, and the substitution relationship is recorded in the remarks field. The interface sealing status inspection uses the interface observation point set as a reference to check for water seepage marks, dripping speed, seepage path length, and whether there is mortar erosion. Leakage levels are categorized into four levels: no seepage, wet marks, dripping, and linear flow. The judgment criteria are solidified in the leakage judgment field of the wet task sheet. A wet mark is defined as continuous dampness at the observation point without dripping. A dripping is determined by counting drips over a 1-minute observation window; drips that can be repeatedly counted are considered dripping, and the count value is written to the dripping count field of the interface status table. A linear flow is defined as the formation of a continuous, flowing water line, and the linear flow identifier is written to... The interface status table includes a line flow identifier field, and the visible water trace length is recorded in the leakage path field. The interface status table must include at least the interface number, observation point number, observation window length, drip count, line flow identifier, leakage path length, judgment time, and judgment person, and must be consistent with the set of observation points referenced in the wet task sheet to ensure that the same observation window and the same point are used when different teams review the data. The 1-minute observation window value is the minimum continuous observation time that can be stably executed by on-site personnel and the team's rotation record rhythm, which must be consistent with the frequency field recorded in the wet task sheet. The treatment branch is fixed by the treatment branch gating field in the wet state task sheet. The treatment action and the review action are bound to the same water level level to avoid giving a qualified conclusion across water levels. When dripping or linear flow occurs during the steady state, the leakage treatment branch is triggered and a treatment number is generated. The dripping treatment adopts a combination of supplementary pre-tightening and secondary retesting. The supplementary pre-tightening increment is recorded according to the target pre-tightening diameter in the interface list and written back to the pre-tightening value field of the interface graded pre-tightening record, while indicating the unit and diameter type. When the target pre-tightening is expressed as a compression rate, the increment value is within 5% to 10% of the target compression rate, derived from the field particle size that can be achieved by pre-tightening adjustment and the compressible margin boundary of the sealing material. When the target pre-tightening is expressed as a compression thickness, the increment value is 0.2 to 0.5 mm or does not exceed the allowable compression margin of the sealing material. One-third of the work is due to the matching requirements between the allowable compression margin of the sealing material and the retest resolution. After the pre-tightening is completed, the misalignment and elevation difference are retested and the interface graded pre-tightening record is written back. Then, steady-state observation is continued at the same water level for no less than 1 hour. If the leakage level does not decrease or continues to deteriorate during the observation period, the treatment branch is upgraded to line flow treatment. The line flow treatment enters the local disassembly and inspection branch. The local disassembly and inspection range is the leakage interface and one adjacent interface. The treatment number, disassembly and inspection range and reset method are registered in the treatment field of the interface list. After reset, the batch verification of the sealing material and the cleaning confirmation of the interface surface are performed. The pre-tightening is reloaded from the initial level according to the graded pre-tightening diameter. After the retest and writing back for each level is completed, the steady-state window is reopened and the steady-state number is reset to ensure that the conclusion of this water level is not affected by the previous defect record. When the attitude index exceeds the reference threshold and the weir top elevation drifts simultaneously, the system enters the attitude anomaly branch and stops filling the weir. The system is then handled by reverting to the next higher water level. The upper limit of the reversion rate is written into the upper limit of the reversion rate field, with a value of, for example, no more than 0.5 meters per hour. This upper limit is determined with reference to the drainage capacity boundary and structural stress change safety requirements of the drainage emergency plan. After reversion, priority is given to adjusting the support pads or weir pads. The adjustment particle size is, for example, 1 to 3 millimeters, determined with reference to the achievable adjustment resolution on site and the control requirements of the allowable weir elevation range. The adjustment action is written back to the component location table, which includes at least the pre-adjustment location value, post-adjustment location value, operator, reset method, and associated steady-state number. After adjustment, steady-state observation is conducted again under the next higher water level conditions for at least 2 hours, and the attitude index is re-measured. Once the attitude index returns to the reference threshold range and the steady-state judgment conditions are met, the system is allowed to resume filling to the target water level. Interface status records are kept using an interface status table, indexed by the interface number. The table includes at least the following fields: water level, steady-state number, steady-state start time, steady-state end time, water level change rate, leakage level, drip count, linear flow identifier, leakage path length, attitude change, treatment number, review task number, review conclusion, responsibility field, and timestamp. The review conclusion is categorized into three types: qualified, pending review, and suspended. "Qualified" indicates that no dripping or higher leakage occurred within the steady-state window of the corresponding water level, and the attitude indicators meet the threshold reference version and the steady-state judgment criteria. "Pending review" indicates a state where the observation period has not ended after treatment. "Suspended" indicates a state where emergency drainage has been triggered or baseline results need to be reviewed. Status changes retain the previous state as a historical entry, and the reason for the change and the associated treatment number are recorded, forming a continuous and traceable record chain. Emergency drainage trigger conditions are written into the emergency drainage trigger field. The emergency drainage trigger field includes at least the trigger type, observation window length, trigger criteria, associated interface number, associated module number, trigger time, handling number, responsibility field, and timestamp. The triggering situation includes at least the appearance of line flow at the interface and the judgment result of two consecutive observation windows still being line flow, or the module attitude change exceeding the allowable range corresponding to the threshold reference version and showing a continuous expanding trend. After triggering, the drainage emergency plan is activated, the status of the associated interface and associated module is updated to paused, the water level rise is stopped in the paused state and the subsequent verification state is blocked. After the cause investigation and handling are completed and written back, the steady state verification is restored from the triggered water level level or the next higher water level. The configuration of nighttime steady state observation personnel is no less than 2 people on duty and the recording is uninterrupted. This is based on the requirements of continuous nighttime observation and data traceability. The duty arrangement is written into the responsibility field of the wet state task sheet. Output a qualified wet pressure holding package. The qualified package is encapsulated into a version number according to the water level record, attitude check, interface status and handling record formed in this section. The interface list status is changed to watertight qualified and the module ledger status is changed to wet pending verification. If the qualified package is not generated or the important boundary interface review conclusion is pending review or suspended, the verification task sheet remains in the wet pressure holding state and is blocked from entering the subsequent verification state.
[0021] S4: Under preset disturbance conditions, perform zonal hydraulic equivalence and boundary integrity verification, collect measurement point response data, and determine boundary and interface numbers according to anomaly criteria. The specific implementation is as follows: After passing the wet pressure test, a zoned hydraulic equivalence and boundary integrity verification is conducted. The verification task sheet is linked to the wet pressure test pass package and the reference version number of the measurement point layout table. A tabular data structure is used as the execution standard for this verification. The verification task sheet should include at least the verification number, boundary group number set, boundary group range description, threshold reference version number, nominal residence time and source document number and version number, nominal flow rate and value caliber, disturbance type code, disturbance execution order, disturbance amplitude, disturbance duration, baseline window, sampling period, sampling window, lower limit of the number of sampling points, response index type, measurement resolution, dissolved oxygen difference threshold, return reference zone, baseline bandwidth, upper limit of baseline bandwidth, safety margin, overflow warning level, abnormal interruption conditions, main change judgment, wake judgment, early judgment criterion, late judgment criterion, dispersion judgment, seepage judgment criterion, and secondary confirmation enablement. The system includes: secondary confirmation range, secondary confirmation window, secondary confirmation prerequisites, responsibility information, and timestamps; nominal residence time is taken from the zoning process control index document and fixed according to the threshold reference version number; nominal flow rate is fixed to a two-option caliber by the nominal flow rate value caliber field, which can be the average of the influent or return flow rate for 10 consecutive minutes before the start of the verification, or the control set value, and remains consistent within the same verification window without switching; dissolved oxygen difference threshold and return reference zone reference boundary caliber correspond to the version number of the list table, and the measurement resolution comes from the measurement point ledger and is consistent with the measurement point number in the measurement point layout table; overflow warning water level is taken from the top elevation of the weir and superimposed with a safety margin, the safety margin is 30 to 100 mm below the top elevation of the weir, and the range is constrained by the allowable fluctuation of the weir, the on-site measurement resolution, and the response time window of the drainage emergency plan, and is fixed in the task sheet; Before the verification begins, a preliminary verification is conducted and a preliminary verification record table is generated. The preliminary verification record table should include at least the following fields: verification item number, verification conclusion, associated boundary number, associated interface number, associated module number, associated component number, disposal number, responsibility field, and timestamp. The verification content should include at least the following: the verification conclusion of the key boundary interface in the wet pressure test package is qualified and there is no pause status; the module ledger status is wet test passed and awaiting verification; the current values of the component location table have all been reset and there are no unreset marks; the threshold reference version number and boundary diameter are consistent with the list table version number; and all measurement points participating in the verification in the measurement point layout table have measurement resolution field and calibration record field. After the verification is passed, the set of boundary group numbers for this verification is determined. The number of boundary groups in a single verification is 1 or 2. The boundary group range is determined by the boundary diameter and the set of adjacent partition boundaries and their associated interface numbers in the list table and written into the boundary group range description field. The number and range of boundary groups are derived from the on-site executable window and positioning resolution requirements. The disturbance condition is an executable disturbance on site. The time series is used as the criterion and is not calculated. There are three disturbance type codes, or two types, or two types from the verification task sheet. When there are more than two types, the flow pulse disturbance is performed first, followed by the water level micro-disturbance and then the backflow disturbance to avoid the prior impact of backflow on global mixing. The flow pulse disturbance is defined as applying a flow increase or decrease at the inlet or outlet, with a duration of 3 to 10 minutes and a disturbance amplitude of 105 to 20% of the nominal flow. The nominal flow is fixed by either the average measured value over the previous 10 minutes or the control setpoint, with the reference being a disturbance intensity range that can generate an observable response on-site without triggering an overflow risk. The duration and amplitude are entered into the disturbance duration and disturbance amplitude fields of the verification task sheet and recorded synchronously with the disturbance identifier. The water level micro-disturbance is determined by temporarily adjusting the water level line through an adjustable weir plate. The water level change is 2 to 10 mm and is maintained for 10 to 30 minutes. The water level change is not less than twice the measurement resolution and not more than one-third of the allowable zone at the weir. The reference is a compromise between the instrument resolution being identifiable and the weir adjustment particle size being controllable. The water level change and the maintenance time are written into the disturbance amplitude field and the disturbance duration field, respectively. The backflow disturbance is defined as a short-term change in the internal backflow valve position or the sludge backflow valve position, with the valve position change range being 10% to 20% and lasting for 10 to 30 minutes. After the valve position change, the valve position must not deviate from the backflow reference zone. The backflow reference zone references the boundary diameter and the version number corresponding to the list table. The reference basis is a controllable range that explicitly displays the backflow short circuit and bypass channel without introducing long-term operational offset. The valve position change range and duration are written into the disturbance range field and the disturbance duration field, and are synchronously written back into the valve position status record. The safety boundary is uniformly controlled by the abnormal interruption condition field. The abnormal interruption condition field includes at least the following situations: the measured water level enters the safety margin range, aeration stops abnormally, the disturbance execution deviates from the predetermined duration by more than 1 minute, and the quality markers of the measuring points are continuously abnormal. The safety margin is 30 to 100 mm below the top elevation of the weir and is consistent with the drainage emergency plan. The disturbance amplitude and duration are both constrained by the above abnormal interruption conditions during the execution process. When any situation is triggered, the interruption reason is recorded according to the verification task sheet and the current disturbance window data collection is terminated. The measurement point response acquisition is bound to the disturbance identification, including a response record table and a boundary record table. The response record table, used for zonal hydraulic equivalence interpretation, must include at least a timestamp, measurement point number, measurement point type, response index type, response index value, valve position status, water level status, disturbance identification, measurement tool number, quality mark, and remarks field. The response index type has a fixed value in the verification task sheet and remains consistent within the same verification window. It can select on-site available quantities such as flow rate reading, liquid level reading change, conductivity response change, and turbidity response change, referencing the measurement capabilities recorded in the source measurement point layout table and the range resolution recorded in the measurement point ledger. The boundary record table, used for complete boundary interpretation, must include at least a timestamp, boundary number, dissolved oxygen values on both sides of the boundary, water level difference on both sides of the boundary, bypass observation point status, aeration status, disturbance identification, quality mark, and remarks field. The bypass observation point status values are no flow mark, intermittent flow mark, and continuous flow mark. The sampling period is 10 to 60 seconds, the sampling window is 2 to 3 times the nominal dwell time, the lower limit of the number of sampling points is not less than 60 points, and the baseline window is 10 minutes before the disturbance. The reference source is the nominal dwell time field and the sampling density requirements that can be covered by manpower on site. The acquisition process is fixed in the verification task sheet as continuous sampling at the baseline window, continuous sampling during the disturbance, and continuous sampling after the disturbance until the trace judgment is met or the upper limit of the sampling window is reached. The disturbance identifier is the baseline in the baseline window, the disturbance during the disturbance, and the recovery after the disturbance. When any of the abnormal interruption conditions are triggered, the corresponding window quality mark is set to invalid and the interruption reason is recorded. After the working condition is restored, the complete sampling window is re-executed according to the same verification task sheet parameters to ensure consistent interpretation. The anomaly criteria employ auditable rules, using nominal dwell time, dissolved oxygen difference threshold, and baseline bandwidth as constraints. The main change determination field is defined as the moment when the deviation of the response index value from the baseline window mean exceeds the baseline bandwidth and remains there for at least two consecutive sampling periods; the moment of first fulfillment is recorded as the main change occurrence time. The baseline bandwidth field is no less than three times the measurement resolution field, and the baseline bandwidth upper limit field is ten times the measurement resolution field. When the upper limit is exceeded, the sensitivity reduction is recorded in the verification task sheet remarks field, and the secondary confirmation enable field is activated. The wake determination field is defined as the moment when the response index value returns to the baseline window mean's positive and negative baseline bandwidth range after the disturbance ends and remains there for at least three consecutive sampling periods; the difference between the moment of first fulfillment and the moment the disturbance ends is recorded as the wake duration. The advance determination field is defined as the main change at the anomaly measurement point. The occurrence time of the main change in the reference partition is more than 0.20 times earlier than the nominal residence time field; the lag criterion field is defined as the tail duration exceeding 0.80 times the nominal residence time field, and at least one measurement point's main change occurrence time lags behind the reference partition's main change occurrence time by more than 0.20 times the nominal residence time field; the dispersion criterion field is defined as the time difference between the main changes of multiple measurement points in the same partition exceeding 0.15 times the nominal residence time field; the nominal residence time field comes from the partition process control index document and is consistent with the version number referenced in the verification task sheet; the measurement resolution field comes from the measurement point ledger and is associated with the measurement point number. The above ratio thresholds are written into the verification task sheet as a unified time scale conversion caliber, automatically converted to the corresponding minutes or seconds according to the nominal residence time field, and the conversion result is recorded in the anomaly criterion trigger table; The penetration criterion field is defined as follows: the dissolved oxygen difference on both sides of the boundary is continuously lower than the dissolved oxygen difference threshold field for at least 20 minutes after disturbance, and covers the corresponding sampling points for at least 20 minutes; or the bypass observation point status is a continuous flow mark for at least 10 minutes, and covers the corresponding sampling points for at least 10 minutes. The dissolved oxygen difference threshold field references the boundary caliber and the version number of the list table, and is consistent with the verification task sheet. The benchmark partition selection field is defined as the partition path with the fewest interfaces in the interface list statistics and no disposal number or reset mark in the component location table within the past 24 hours. If no partition path meets the conditions, the segment with the fewest interfaces in the same partition is taken as the benchmark segment, and the substitution relationship is recorded in the remarks field. To ensure verifiability, the anomaly criterion trigger table includes at least the following fields: criterion item number, measurement point number, boundary number, interface number candidate set, main change occurrence time, wake duration, dissolved oxygen difference time period, bypass observation point status time period, reference threshold version number, and confirmation identifier. The positioning system employs a two-tiered chain: a mapping from measurement points to boundaries and a mapping from boundaries to interfaces. The mapping relationships reference established records and are fixed with the verification positioning package. The measurement point layout table includes at least the following fields: measurement point number, zone, adjacent boundary number, measurement resolution, and calibration record. When triggering early, late, or dispersed criteria, a candidate set of boundaries is generated based on the adjacent boundary numbers of the abnormal measurement points and written into the abnormality criterion trigger table. The boundary caliber and list table include at least the following fields: boundary number, set of associated interface numbers, set of associated component numbers, relationship between flow outlets or weirs, cross-module relationship of flow guiding components, and proximity of return inlets. After the candidate set of boundaries is determined, a candidate set of interfaces is generated from the set of associated interface numbers and prioritized. The prioritization rule prioritizes interfaces directly connected to flow outlets or weirs, followed by cross-module relationships of flow guiding components. The block connection interface, again near the return inlet interface, sorts the results and writes them into the suggested correction priority table. To improve positioning resolution, secondary confirmation can be optionally enabled. The secondary confirmation enable field is set to "enabled". The secondary confirmation precondition field is set to "indicator fluctuation within baseline window does not exceed baseline bandwidth and no abnormal interruption condition is triggered". The secondary confirmation amplitude field is set to half of the original disturbance amplitude. The secondary confirmation window field is set to 0.5 to 1.0 times the nominal dwell time field, and not less than 30 minutes. The disturbance type code remains unchanged and sampling is repeated. If the abnormal boundary number and the interface number are consistent after secondary confirmation, the confirmation flag is set to "confirmed". Otherwise, the confirmation flag is set to "pending review" and the reason for pending review and the candidate set are recorded in the verification positioning package to avoid unstable abnormalities causing pointing drift in subsequent processing. The output is a verification and positioning package, which includes at least the following fields or files: hydraulic response record table, boundary record table, anomaly criterion trigger table, boundary number list, interface number list, suggested correction priority table, verification task snapshot, and version number information. The interface list, boundary caliber, and list status fields are used to write back the anomaly type code and confirmation identifier. The anomaly type code takes one or more combinations of types such as advanced, delayed, dispersed, and seepage. For combinations of types, the primary anomaly type is recorded first, and secondary anomaly types are noted. The confirmation identifier takes the values of confirmed or pending review. For those pending review, the verification and positioning package retains a candidate set and review information. The candidate set includes at least the following fields: boundary number, interface number, trigger criterion entry, secondary confirmation execution status, and reason for pending review. The suggested correction priority table lists the priority numbers for interfaces in the candidate set, with the sorting rule being: interfaces directly connected to the flow outlet or weir prioritized, followed by interfaces connecting to the flow guide components across modules, and then interfaces adjacent to the return inlet. It lists the associated component number set and the recommended review task number.
[0022] S5: Execute module-level reversible correction based on the serial number, adjust the overcurrent limiting, flow guiding components, weir components, return inlet components, and gas supply distribution components, complete the review and update the ledger and verification plan, specifically as follows: After the verification positioning package is generated, it enters the module-level reversible correction and verification closed loop to input the verification positioning package and component location table. The input verification positioning package confirms the boundary number, interface number, and exception type code as the corrected object list. The correction task sheet is based on the correction number as the unique index and includes at least the following fields: boundary number, interface number, exception type code, priority number, control point type, component number set, location value unit field, allowable range reference number, adjustment granularity reference number, alignment allowable band reference number, valve position reference band reference number, preset verification task number, status field, rollback count, rerun identifier number, responsibility field, and timestamp. When the confirmation identifier is "pending verification", the task status is written with the blocking reason number and candidate set entries and retained until the confirmation identifier is updated to "confirmed" before entering the correction process. When the component location table entry corresponding to the component number set lacks the allowable range field or reset method field, the task is marked as "not executable" and the blocking reason number is written back to avoid adjustments when there are no boundary constraints or rollback criteria. The correction process uses control points as the smallest adjustment unit. A control point can be a single component or a group of strongly coupled components. A group of strongly coupled components refers to a combination of components that have a linked effect on the same flow stream or distribution boundary, such as a flow-limiting insert and weir plate combination acting synchronously in the same flow outlet, a flow guide and valve position combination acting synchronously in the same return inlet, or a balance plate and branch valve position combination acting synchronously in the same air supply branch. Each correction number only adjusts the position of one control point once per correction. After adjustment, a verification is performed. Before verification, other control points are not adjusted to avoid the superposition of multiple variables that could lead to unreviewable abnormal attributions. To ensure consistency in single adjustments... The criteria for determining limits and boundaries must include at least the following fields in the correction task sheet: allowable range reference number, adjustment granularity reference number, alignment allowable zone reference number, valve position reference zone reference number, and position value unit field. The allowable range reference number and adjustment granularity reference number are from the component location table, the alignment allowable zone reference number is from the alignment retest table, and the valve position reference zone reference number is from the caliber freeze table. The position value after adjustment must meet the allowable range and alignment allowable zone constraints and be taken within the valve position reference zone. The measurement method defined in the position value unit field must remain unchanged. The adjustment amplitude of a single adjustment must not exceed the upper limit corresponding to the adjustment granularity field and must not exceed the boundary corresponding to the allowable range field. The correction process is controlled by a state machine. Status fields are set in the correction task sheet, categorized into seven types: pending correction, in progress correction, pending review, review passed, review failed, rollback, and upgraded disassembly / inspection. State transition conditions are bound to record write-back rules. The correction task sheet must include at least the following fields: correction number, boundary number, interface number, control point identifier, component number set, allowable range reference number, adjustment granularity reference number, review task number, rollback number, rollback count, disassembly / inspection number, rerun identifier, responsibility field, and timestamp. State transitions are defined by event triggering, with the state changing from pending correction to in progress correction to complete control point adjustment and generate a correction record. The following are trigger events: The status changes from "In Correction" to "Pending Review," triggering the generation of a review task number and freezing of the current disturbance parameter set; the status changes from "Pending Review" to "Review Passed" or "Review Failed," triggering the conclusion that the review record item satisfies or does not satisfy the criterion item; the status changes from "Review Failed" to "Rollback," triggering the execution of a reset operation and generating a rollback number; the status changes from "Rollback" to "Upgraded Disassembly and Inspection," triggering the event when the rollback count reaches the upper limit or the component position value touches the allowable range boundary, the review record still shows the trigger criterion item, and the criterion item is still satisfied. Simultaneously, a disassembly and inspection number and a rerun identifier are generated for subsequent traceability and rerun management. The correction path is selected based on a combination of anomaly type code and boundary type, and remains auditable. When the anomaly type code is "early" and the boundary type is "overflow boundary," the path is entered for overflow limiting. The adjustment object can be either the opening of the limiting insert or the position of the orifice insert. The opening is recorded on a scale from 0 to 100, and the single adjustment range is no more than 20% of the current opening in the component position table before correction, to limit the sudden change in flow bundle caused by one-time adjustment and to retain space for backtracking and verification. When the anomaly type code is "dispersion" or "dead zone" and the associated component type is "guide component," the path is entered for guide adjustment. The adjustment object can be either the insertion depth of the guide plate or the angle of the guide plate. The single adjustment amount for the insertion depth is no more than 50 mm, and the single adjustment amount for the angle is no more than 2 degrees. When the anomaly type code is "permeability" and the difference in dissolved oxygen on both sides of the boundary triggers the permeability criterion, the path is entered for weir and boundary closure. The adjustment objects can be either the adjustable weir plate elevation or the position of the boundary closure insert. The single adjustment amount for the weir plate is 1 to 3 mm. Meters, and satisfying the following conditions: the top elevation of the weir does not exceed the alignment allowable zone, and the bypass opening formed by the boundary closed insert does not exceed the boundary diameter and the allowable bypass opening diameter in the list; when the abnormality type code is backflow short circuit and the backflow inlet is located, enter the backflow inlet guide path, and the adjustment object can be the direction of the backflow inlet guide plate and the backflow valve position; the valve position is recorded on a scale from 0 to 100, and the single adjustment amount of the valve position is 10 to 20 scale points, and the valve position is kept within the valve position reference zone after adjustment; when the abnormality type code is that the difference between gas supply related measuring points in the same zone increases and is associated with the gas supply branch, enter the gas supply distribution path, and the adjustment object can be the gas supply equalization plate and the branch valve position, and the branch valve position is recorded on a scale from 0 to 100, and the single adjustment amount is no more than 10 scale points; the above numerical ranges are derived from the allowable range of components, the adjustment granularity that can be realized on site, the alignment retest allowable zone and the valve position reference zone, etc., which have been frozen, to avoid introducing reverse deviation due to excessive adjustment at one time and to retain backlash space; When multiple boundaries are simultaneously abnormal, the handling order follows the flow direction recorded in the interface direction code or boundary group range description, handling the boundary corresponding to the upstream direction code first, and then handling the boundary corresponding to the downstream direction code. Component switching can only be performed after the triggering conditions are met. The triggering conditions are at least that the upper limit of the backtracking count of the same control point is met, the upper limit of the control point position value reaches the allowable range boundary, and the verification record entry shows that the triggering criterion entry has moved from the target boundary to the adjacent boundary. The adjacent boundary is based on the adjacent boundary number field in the measurement point layout table, and the value is the boundary number within the boundary number set in the boundary group range description. Component switching is not performed where the boundary number is outside the boundary number. The correspondence between the boundary group range description and the measurement point layout table is saved through the snapshot of the verification task sheet. The switching conditions are verifiable and traceable. After the correction is executed, a correction record table is generated, which is stored in a one-to-one correspondence with the review record table. The correction record table is indexed by the correction number and includes at least the boundary number, interface number, control point type, component number set, position value unit, position value before adjustment, position value after adjustment, adjustment amount, adjustment time, operator, review task number, reset method reference number, rollback number, rollback count, snapshot version number, responsibility field, and timestamp. The position value before adjustment references the component position table snapshot and simultaneously records the snapshot version number. The position value after adjustment is obtained through component scale retesting or positioning retesting and written back. When the control point is a strongly coupled component group, the position values before and after adjustment of the components within the group are recorded simultaneously. The review references trigger exceptions. The parameter set of the corresponding verification task sheet must be consistent with the disturbance type code, disturbance amplitude, sampling period, sampling window, and criterion entries to ensure comparability of the verification. The verification record table is indexed by the verification task number and includes at least the reference verification number, reference correction number, disturbance type code, disturbance amplitude, sampling period, sampling window, trigger criterion entry, confirmation identifier, verification conclusion, associated boundary number, associated interface number, responsibility field, and timestamp. The verification conclusion can be categorized as passed, failed, pending verification, or suspended. Passing corresponds to the original trigger criterion entry no longer being met and the boundary-related threshold returning to the caliber frozen threshold band. Pending verification corresponds to verification interruption or data quality abnormalities that render this window invalid. Suspended corresponds to upgrade disassembly / inspection or stoppage for security reasons. If the review fails, the process is returned. The return action restores the component to its pre-adjustment position value according to the reset method reference number. The return number and return count are written in the return record. The upper limit of the return count is three times for the same boundary and two times for the same interface. This is set according to the single boundary correction window on site and the control requirements to avoid structural disturbance caused by repeated trial and error. If the return count exceeds the upper limit or the component position value exceeds the allowable range boundary, and there are still trigger criteria items, the process is upgraded for disassembly and inspection. The upgraded disassembly and inspection range is the target interface corresponding to the boundary diameter and the interface number set associated with the list table, as well as one interface. The disassembly and inspection number and rerun identifier number are written in the correction task sheet. The rerun water level level is the highest completed water level level corresponding to the triggering abnormal boundary. The rerun verification number is the rerun sequence number appended to the rerun verification number. Only after the rerun is completed and a rerun record is formed can the boundary be reviewed for correction. After the corrective action review is passed, the current position in the component location table is updated to the delivery baseline position and a lock mark is written. Simultaneously, the pass code and timestamp are written back to the module ledger and interface list. The pass code can be either passed, failed, pending review, or paused, and must be consistent with the review conclusion. The corrective action delivery package should include at least the following files: a snapshot of the corrective action task sheet, a corrective action record table, a review record table, a snapshot of the updated component location table, a snapshot of the updated module ledger, a snapshot of the updated interface list, a list of boundary numbers and interface numbers, and version information. Under the boundary number entry, the locked set of component numbers and the corresponding review task number should be associated. The verification plan should include at least the following fields: verification cycle, verification boundary number set, verification disturbance method code, verification window, verification threshold, trigger condition, emergency corrective action path, observation window length, observation window sequence number, responsibility field, and timestamp. The verification cycle can be selected as once daily for the first 7 days of operation and once weekly for the next 30 days. The verification window value is a name. The nominal dwell time is 0.5 to 1.5 times the nominal dwell time, and the total duration of a single verification does not exceed 3 hours. When the nominal dwell time is less than 30 minutes, the verification window is set to 30 to 60 minutes. The basis for this setting is that deviations are more easily manifested in the early stage of operation and the on-site executable window is limited. The triggering conditions include at least the boundary-related threshold being below the threshold zone for 2 consecutive hours, the return flow deviating from the reference zone for 3 consecutive times under the condition that the return valve position remains unchanged, and the hydraulic response of the sampling inspection meeting the advance judgment criteria. The judgment of 2 consecutive hours and 3 consecutive times is based on the observation window number corresponding to the verification window and the sampling cycle, and the observation window length and version number are fixed. The emergency correction path references the correction attribution rule and binds the component number set and the reset method reference number. The on-site organization constraint is that the correction and verification of a single boundary is completed within 4 to 8 hours. The upgraded dismantling and inspection is carried out locally according to the boundary diameter and the scope determined by the list, and the dismantling and inspection number and recovery record are written back. The basis for this setting is to avoid repeated trial and error forming a bottleneck in the construction period and to control the scope of dismantling and inspection.
