Description

Technical Field

[0001] This invention relates to the field of wastewater treatment and process control, and in particular to an adaptive wastewater treatment hydrolysis acidification water distribution-reaction synergistic control system. Background Technology

[0002] Hydrolysis acidification tanks are important pretreatment structures in biological wastewater treatment processes, often used to improve the biodegradability of macromolecular organic matter and enhance subsequent treatment conditions. In existing technologies, the water distribution or reaction state of the hydrolysis acidification tank is typically adjusted by monitoring influent chemical oxygen demand (COD), influent flow rate, oxidation-reduction potential (ORP), volatile fatty acid concentration, sludge concentration, and distribution branch flow rate to maintain stable tank operation.

[0003] However, most existing technologies focus on optimizing a single water distribution or regulating a single reaction, lacking a holistic understanding of the spatial distribution of the hydrolysis-dominant zone, acid-producing zone, and buffer zone. This makes it difficult to detect imbalances in microbial functional zones caused by functional boundary drift, functional overlap, and functional loss. Furthermore, it is difficult to establish a three-domain coupling correspondence between the water distribution characterization, reaction domain characterization, and microbial functional zone spatial distribution map. Consequently, water distribution regulation and reaction regulation are difficult to coordinate and link, microbial functional zones cannot achieve spatial self-reconstruction, and the hydrolysis acidification tank lacks adaptive regulation capability under load fluctuation conditions. Summary of the Invention

[0004] One objective of this invention is to propose an adaptive wastewater treatment hydrolysis acidification water distribution-reaction synergistic control system. This invention is based on the spatial distribution identification of microbial functional zones and implements synergistic control of water distribution and reaction in the hydrolysis acidification tank, which has the advantages of high stability, strong adaptability and precise control.

[0005] An adaptive wastewater treatment hydrolysis acidification water distribution-reaction synergistic control system according to an embodiment of the present invention includes:

[0006] The data acquisition module is used to collect the operating status data of the hydrolysis acidification tank, perform preprocessing, and generate a standardized operating status dataset.

[0007] The functional zone identification module is used to construct a set of regional functional representations based on a standardized operational status dataset, and to identify hydrolysis-dominant zones, acid-producing-dominant zones, and buffer zones, generating a spatial distribution map of microbial functional zones.

[0008] The imbalance characterization generation module is used to identify functional boundary drift regions, functional overlap regions, and functional loss regions based on the spatial distribution map of microbial functional regions, and generate a set of microbial functional region imbalance characterizations.

[0009] The water distribution construction module is used to construct a water distribution characterization based on the microbial functional zone imbalance characterization set, and to determine the target water distribution induction area corresponding to the microbial functional zone imbalance characterization set.

[0010] The module for constructing reaction domains and establishing coupling relationships is used to construct reaction domain distribution representations based on the microbial functional region imbalance characterization set and the distribution characterization of water distribution areas, and to establish the three-domain coupling correspondence between the distribution characterization of water distribution areas, the reaction domain distribution representations, and the spatial distribution map of microbial functional regions.

[0011] The collaborative regulation execution module is used to form a water distribution-reaction collaborative regulation sequence based on the three-domain coupling correspondence, and to execute the operation regulation of the hydrolysis acidification tank to drive the spatial self-reconstruction of the microbial functional zone;

[0012] The closed-loop update and correction module is used to continuously collect the operating status data of the hydrolysis acidification tank, update the three-domain coupling correspondence, cyclically correct the water distribution-reaction synergistic control sequence, and complete the adaptive control of the hydrolysis acidification tank.

[0013] Optionally, the data acquisition module includes:

[0014] Data on influent chemical oxygen demand and influent flow rate at the inlet of the hydrolysis acidification tank were obtained respectively. Data on oxidation-reduction potential, volatile fatty acid concentration and sludge concentration at multiple monitoring locations in the tank were also obtained. Simultaneously, the flow rate data of each water distribution branch at the corresponding collection time were obtained to form the original dataset of the operating status.

[0015] Perform time synchronization on various types of data in the original dataset of the running status to generate a time-aligned data sequence;

[0016] Anomaly removal is performed on each type of data in the time-aligned data sequence to generate a data sequence after anomaly removal, and missing parts are filled to generate a complete state data sequence;

[0017] Normalize the data in the complete state data sequence to generate a standardized operating state dataset.

[0018] Optionally, the function area identification module includes:

[0019] Based on the standardized operating status dataset, the spatial location of the hydrolysis acidification tank is divided into grids according to the length, width and depth directions of the tank, generating multiple regional units, and establishing a one-to-one mapping relationship between each regional unit and the corresponding spatial location of the tank.

[0020] For each regional unit, the substrate input intensity is extracted by combining the influent chemical oxygen demand data, influent flow rate data and flow rate data of each water distribution branch at the corresponding time.

[0021] For each regional unit, the acidification propulsion intensity is extracted by combining the redox potential data and volatile fatty acid concentration data at the corresponding time.

[0022] Based on the sludge concentration data of each regional unit at the corresponding time, the sludge enrichment intensity is extracted;

[0023] The substrate input intensity, acidification propulsion intensity and sludge enrichment intensity corresponding to each regional unit are combined accordingly to generate a set of regional functional characterizations for each regional unit.

[0024] Based on the regional functional characterization set corresponding to each regional unit, multiple regional units are functionally identified. Regional units with substrate input intensity higher than acidification propulsion intensity and sludge enrichment intensity are identified as hydrolysis-dominant zones. Regional units with acidification propulsion intensity higher than substrate input intensity and sludge enrichment intensity are identified as acid-producing-dominant zones. Regional units with sludge enrichment intensity higher than substrate input intensity, acidification propulsion intensity higher than substrate input intensity, and forming a continuous connection with adjacent regional units are identified as buffer zones.

[0025] Based on the spatial distribution of each regional unit in the pool, the hydrolysis-dominant zone, acid-producing zone, and buffer zone are spatially organized to generate a spatial distribution map of microbial functional zones.

[0026] Optionally, the spatial distribution map of the microbial functional zones is a regional functional distribution map formed by marking and organizing the distribution of the hydrolysis-dominant zone, acid-producing zone, and buffer zone corresponding to each regional unit in the hydrolysis acidification tank in the spatial location of the tank.

[0027] Optionally, the imbalance representation generation module includes:

[0028] Based on the spatial distribution map of microbial functional zones, the functional type of each regional unit in the pool is extracted, and the combination of adjacent regional units where the functional type changes is identified, generating the corresponding set of functional boundary regions.

[0029] For each set of functional boundary regions, extract the boundary center position corresponding to each set of functional boundary regions to generate the functional boundary position;

[0030] Based on the changes in the boundary center position of each functional boundary region set at two consecutive acquisition times, the boundary migration path of each functional boundary region set from the previous acquisition time to the next acquisition time is extracted, and the boundary migration direction is generated.

[0031] Based on the boundary center position offset of each functional boundary region set at two consecutive acquisition times, the boundary displacement degree of each functional boundary region set in the corresponding acquisition time period is extracted to generate the boundary migration amplitude.

[0032] Based on the adjacency relationship of each regional unit, the continuous distribution length, continuous distribution range and cross-regional connection status between regional units of the same functional type are extracted to generate regional functional continuity;

[0033] The boundary migration direction, boundary migration magnitude, and regional functional continuity are correlated accordingly, and the functional boundary regions that continuously migrate towards the same functional area and whose boundary migration magnitude exceeds the preset boundary drift threshold are identified as functional boundary drift regions.

[0034] The set of functional boundary regions where adjacent regional units simultaneously possess two types of regional functions and where the continuity of regional functions decreases is identified as functional overlap regions.

[0035] A set of functional boundary regions where the continuity of regional functions is interrupted and adjacent regional units cannot form a functional connection is identified as a functional missing region.

[0036] The functional boundary drift regions, functional overlap regions, and functional loss regions are summarized and organized to generate a microbial functional region imbalance characterization set.

[0037] Optionally, the water area construction module includes:

[0038] Read the spatial location of each functional boundary drift region, functional overlap region, and functional missing region in the microbial functional region imbalance characterization set, and extract the set of regional units corresponding to the spatial location of the pool to generate an imbalanced regional unit set;

[0039] Based on the set of unbalanced regional units, combined with the flow data of each water distribution branch and the spatial location of the pool corresponding to each regional unit, the water distribution arrival relationship of each water distribution branch to each regional unit is determined, the coverage of each regional unit receiving the input from the water distribution branch at the corresponding collection time is statistically analyzed, and the water distribution coverage status is generated.

[0040] For each regional unit in the set of unbalanced regional units, based on the distribution difference of the flow data of each water distribution branch in the spatial position of the pool at the corresponding collection time, the changes in the concentrated position of water distribution and the changes in the deviation position of water distribution relative to its adjacent regional units are extracted to generate the water distribution offset state.

[0041] For each regional unit in the set of unbalanced regional units, the flow data of each corresponding water distribution branch is correlated with the substrate input intensity of each regional unit. The substrate input continuity after receiving water distribution input and the water distribution transfer connection between adjacent regional units are extracted to generate the water distribution acceptance status.

[0042] The water distribution coverage state, water distribution offset state, and water distribution acceptance state are organized according to the same regional unit to form a combination of water distribution states corresponding to each regional unit, thereby generating a water distribution distribution characterization.

[0043] Based on the water distribution characterization, regional units with insufficient water distribution coverage and interrupted water distribution reception are identified as functional compensation candidate regions. Regional units with water distribution offset extending towards the interior of the functional boundary drift region are identified as boundary correction candidate regions. Regional units with overlapping water distribution coverage and intersecting water distribution offset are identified as distribution adjustment candidate regions.

[0044] The candidate regions for functional compensation, boundary correction, and distribution adjustment are matched with the microbial functional zone imbalance characterization set to determine the target water distribution induction region corresponding to the microbial functional zone imbalance characterization set.

[0045] Optionally, the reaction domain construction and coupling relationship establishment module includes:

[0046] Read the regional units corresponding to the functional boundary drift areas, functional overlap areas and functional loss areas in the microbial functional zone imbalance characterization set, and extract the distribution characteristics of the distribution water area, acidification promotion intensity and sludge enrichment intensity of the regional units to generate a set of reaction analysis regional units;

[0047] For each region unit in the reaction analysis region unit set, combined with the change of the corresponding acidization propulsion intensity at continuous acquisition time, the reaction propulsion position change and reaction propulsion continuation of each region unit are extracted to generate the reaction propulsion state;

[0048] For each regional unit in the reaction analysis regional unit set, based on the distribution of the corresponding acidification propulsion intensity and sludge enrichment intensity in the spatial location of the pool, the degree of residence of the reaction in the target regional unit and the obstruction of its transmission to adjacent regional units are extracted to generate the reaction retention state.

[0049] The acidification promotion intensity, sludge enrichment intensity and water distribution characteristics of each regional unit are correlated, and the reaction transmission continuity and regional function inheritance between each regional unit and adjacent regional units are extracted to generate the reaction inheritance status.

[0050] Organize the reaction advance state, reaction stagnation state and reaction acceptance state corresponding to the same regional unit to form the reaction state combination corresponding to each regional unit, and generate the reaction domain distribution characterization.

[0051] Based on the distribution characterization of water distribution areas, the distribution characterization of reaction areas, and the spatial distribution map of microbial functional zones, the correspondence between the water distribution location and the reaction advancement location, the correspondence between the water distribution transfer state and the reaction acceptance state, and the correspondence between the regional functional type and the reaction state combination of each regional unit are extracted to generate a set of three-domain corresponding units.

[0052] The correspondence between the regional units in the three-domain corresponding unit set is summarized and organized to establish a three-domain coupling correspondence between the distribution characterization of water area, the distribution characterization of reaction domain, and the spatial distribution map of microbial functional zones.

[0053] Optionally, the coordinated control execution module includes:

[0054] Read the water distribution characterization, reaction domain distribution characterization and regional functional type of each regional unit in the three-domain coupling correspondence, extract the functional compensation demand and reaction acceptance demand corresponding to the target water distribution induced area, and generate a set of regional regulation demand.

[0055] For each regional unit in the set of regional regulation needs, based on the corresponding water distribution coverage status, water distribution offset status and water distribution acceptance status, determine the insufficient water distribution effect, water distribution offset correction amount and water distribution transmission compensation amount of each water distribution branch to the target water distribution induced area, and generate the branch flow regulation amount corresponding to each water distribution branch.

[0056] Based on the branch flow regulation amount corresponding to each regional unit and the distribution order of each regional unit in the pool space in the set of regional control needs, the sequential action time of each water distribution branch on the target water distribution induction area is determined, and the time-sharing water distribution sequence is generated.

[0057] Based on the branch flow regulation amount, time-sharing water distribution sequence, and pool spatial location coverage of the target water distribution induction area, the flow distribution share of each water distribution branch in different target water distribution induction areas is determined, and the zoned water distribution ratio is generated.

[0058] For each regional unit in the set of regional regulation needs, based on the corresponding reaction advancement state, reaction retention state and reaction acceptance state, and combined with the distribution order of regional functional types in the spatial location of the pool, the sequence of reaction advancement, reaction slow release and reaction acceptance compensation for each regional unit is determined, and the reaction regulation sequence is generated.

[0059] The branch flow regulation amount, time-sharing water distribution sequence, zone water distribution ratio and reaction regulation sequence are organized according to the same target water distribution induction area to form a water distribution-reaction coordinated regulation sequence.

[0060] Based on the water distribution-reaction synergistic regulation sequence, the output flow and duration of each water distribution branch are adjusted, and the reaction advancement process corresponding to the target water distribution induction area is synchronously regulated according to the reaction regulation sequence, so as to drive the spatial self-reconstruction of the microbial functional zone.

[0061] Optionally, the functional compensation requirement refers to the additional water distribution and substrate input required by the target water distribution induction area to restore the corresponding area's functional type, and the reaction acceptance requirement refers to the reaction connection requirement that the target water distribution induction area must meet to restore the continuous reaction transmission and functional acceptance relationship between adjacent area units.

[0062] Optionally, the closed-loop update correction module includes:

[0063] After the hydrolysis acidification tank is regulated and adjusted according to the water distribution-reaction synergistic control sequence, the operating status data of the hydrolysis acidification tank is continuously collected and preprocessed to generate an updated standardized operating status dataset.

[0064] Based on the updated standardized operational status dataset, the substrate input intensity, acidification propulsion intensity and sludge enrichment intensity corresponding to each regional unit were re-extracted, and the spatial distribution map of microbial functional zones was updated.

[0065] Based on the updated spatial distribution map of microbial functional regions, functional boundary drift regions, functional overlap regions, and functional loss regions are re-identified to generate an updated microbial functional region imbalance characterization set.

[0066] Based on the updated characterization set of microbial functional zone imbalance, the characterization of water distribution and reaction domain distribution were updated;

[0067] Based on the updated water distribution characterization, updated reaction domain distribution characterization, and updated microbial functional zone spatial distribution map, an updated three-domain coupling correspondence was established, and an updated water distribution-reaction synergistic regulation sequence was generated.

[0068] Based on the updated water distribution-reaction synergistic regulation sequence, the operation and regulation process of the hydrolysis acidification tank is cyclically corrected to achieve adaptive synergistic regulation of the hydrolysis acidification tank.

[0069] The beneficial effects of this invention are:

[0070] This invention constructs a holistic control chain around the spatial distribution of microbial functional zones within the hydrolysis-acidification tank. This eliminates the disconnect between water distribution and reaction control in wastewater treatment, establishing a synergistic relationship around the hydrolysis-dominant zone, acid-producing zone, and buffer zone. Compared to existing technologies that primarily adjust single operating parameters locally, this invention first constructs a set of regional functional characterizations based on operational data. It then further identifies the hydrolysis-dominant zone, acid-producing zone, and buffer zone, generating a spatial distribution map of microbial functional zones. Furthermore, it identifies functional boundary drift areas, overlapping areas, and missing areas, generating a set of microbial functional zone imbalance characterizations. This allows for the direct identification of functional imbalances within the hydrolysis-acidification tank. This transforms previously hidden functional distribution anomalies within the tank into extractable, analyzable, and controllable objects, providing a clear basis for subsequent adaptive control.

[0071] Building upon this foundation, the present invention further constructs a distribution characterization of the water distribution area and a reaction domain distribution characterization, and establishes a three-domain coupling correspondence between the water distribution characterization, the reaction domain distribution characterization, and the spatial distribution map of microbial functional zones. This allows for unified organization of the water distribution location, reaction propagation status, and regional functional distribution status within the same regulatory framework. The resulting water distribution-reaction synergistic regulation sequence is no longer an isolated correction targeting the flow rate of a single water distribution branch or the reaction status of a single region, but rather a holistic adjustment addressing the functional compensation and reaction acceptance needs of the target water distribution-induced region. This drives spatial self-reconstruction of microbial functional zones. In this way, the hydrolysis acidification tank can gradually restore the continuous transition and functional acceptance relationship between the hydrolysis-dominant zone, the buffer zone, and the acid-producing-dominant zone during operation, reducing the adverse effects of functional boundary drift, functional overlap, and functional loss on the overall treatment process. This improves the matching degree between water distribution and reaction propagation, enhancing the stable operation, adaptive regulation, and continuous treatment capabilities of the hydrolysis acidification tank under load fluctuation conditions.

[0075] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0076] refer to Figure 1 and Figure 2 An adaptive wastewater treatment hydrolysis acidification water distribution-reaction synergistic control system includes:

[0077] The data acquisition module is used to collect the operating status data of the hydrolysis acidification tank, perform preprocessing, and generate a standardized operating status dataset.

[0078] The functional zone identification module is used to construct a set of regional functional representations based on a standardized operational status dataset, and to identify hydrolysis-dominant zones, acid-producing-dominant zones, and buffer zones, generating a spatial distribution map of microbial functional zones.

[0079] The imbalance characterization generation module is used to identify functional boundary drift regions, functional overlap regions, and functional loss regions based on the spatial distribution map of microbial functional regions, and generate a set of microbial functional region imbalance characterizations.

[0080] The water distribution construction module is used to construct a water distribution characterization based on the microbial functional zone imbalance characterization set, and to determine the target water distribution induction area corresponding to the microbial functional zone imbalance characterization set.

[0081] The module for constructing reaction domains and establishing coupling relationships is used to construct reaction domain distribution representations based on the microbial functional region imbalance characterization set and the distribution characterization of water distribution areas, and to establish the three-domain coupling correspondence between the distribution characterization of water distribution areas, the reaction domain distribution representations, and the spatial distribution map of microbial functional regions.

[0082] The collaborative regulation execution module is used to form a water distribution-reaction collaborative regulation sequence based on the three-domain coupling correspondence, and to execute the operation regulation of the hydrolysis acidification tank to drive the spatial self-reconstruction of the microbial functional zone;

[0083] The closed-loop update and correction module is used to continuously collect the operating status data of the hydrolysis acidification tank, update the three-domain coupling correspondence, cyclically correct the water distribution-reaction synergistic control sequence, and complete the adaptive control of the hydrolysis acidification tank.

[0084] In this embodiment, the data acquisition module includes:

[0085] Data on influent chemical oxygen demand and influent flow rate at the inlet of the hydrolysis acidification tank were obtained respectively. Data on oxidation-reduction potential, volatile fatty acid concentration and sludge concentration at multiple monitoring locations in the tank were also obtained. Simultaneously, the flow rate data of each water distribution branch at the corresponding collection time were obtained to form the original dataset of the operating status.

[0086] The influent chemical oxygen demand (COD) data is a detection data characterizing the load level of oxidizable organic matter in the wastewater entering the hydrolysis acidification tank; the influent flow rate data is a detection data characterizing the volume change of wastewater entering the hydrolysis acidification tank per unit time; the oxidation-reduction potential (ORP) data is a detection data characterizing the change state of the reduction environment and reaction environment in each area unit of the hydrolysis acidification tank; the volatile fatty acid concentration data is a detection data characterizing the accumulation level of intermediate acidification products generated by the conversion of organic matter during the hydrolysis acidification process; the sludge concentration data is a detection data characterizing the degree of enrichment of activated sludge and the distribution state of biomass in each area unit; and the flow rate data of each water distribution branch is a detection data characterizing the distribution state of the amount of wastewater delivered by each water distribution branch to different areas of the hydrolysis acidification tank at the corresponding time.

[0087] Perform time synchronization on various types of data in the original dataset of the running status to generate a time-aligned data sequence;

[0088] Anomaly removal is performed on each type of data in the time-aligned data sequence to generate a data sequence after anomaly removal, and missing parts are filled to generate a complete state data sequence;

[0089] Normalize the data in the complete state data sequence to generate a standardized operating state dataset.

[0090] In this embodiment, the functional area identification module includes:

[0091] Based on the standardized operating status dataset, the spatial location of the hydrolysis acidification tank is divided into grids according to the length, width and depth directions of the tank, generating multiple regional units, and establishing a one-to-one mapping relationship between each regional unit and the corresponding spatial location of the tank.

[0092] For each regional unit, the substrate input intensity is extracted by combining the influent chemical oxygen demand data, influent flow rate data and flow rate data of each water distribution branch at the corresponding time.

[0093] For each regional unit, the acidification propulsion intensity is extracted by combining the redox potential data and volatile fatty acid concentration data at the corresponding time.

[0094] Based on the sludge concentration data of each regional unit at the corresponding time, the sludge enrichment intensity is extracted;

[0095] Substrate input intensity refers to the concentration and input level of organic substrate received by a certain regional unit at a corresponding time, which is used to characterize the state of the regional unit receiving influent organic load. Acidification propulsion intensity refers to the activity and transformation state of the hydrolysis and acidification reaction in a certain regional unit at a corresponding time, which is used to characterize the reaction propulsion state of the transformation from organic substrate to acidification intermediate products in the regional unit. Sludge enrichment intensity refers to the concentration of activated sludge aggregation and retention in a certain regional unit at a corresponding time, which is used to characterize the carrying capacity of microbial biomass and the basis of biological action in the regional unit.

[0096] The substrate input intensity, acidification propulsion intensity and sludge enrichment intensity corresponding to each regional unit are combined accordingly to generate a set of regional functional characterizations for each regional unit.

[0097] Based on the regional functional characterization set corresponding to each regional unit, multiple regional units are functionally identified. Regional units with substrate input intensity higher than acidification propulsion intensity and sludge enrichment intensity are identified as hydrolysis-dominant zones. Regional units with acidification propulsion intensity higher than substrate input intensity and sludge enrichment intensity are identified as acid-producing-dominant zones. Regional units with sludge enrichment intensity higher than substrate input intensity, acidification propulsion intensity higher than substrate input intensity, and forming a continuous connection with adjacent regional units are identified as buffer zones.

[0098] A region unit that forms a continuous connection with an adjacent region unit is one that is not isolated from its neighboring region units in terms of spatial location within the pool, but rather maintains a connection in terms of regional functional changes. This allows the substrate conversion process corresponding to the upstream region unit and the acidification reaction process corresponding to the downstream region unit to continue to be transmitted and transitioned within the region unit, thereby enabling the region unit to play a functional connection and reaction succession role between the hydrolysis-dominant zone and the acid-producing-dominant zone.

[0099] Based on the spatial distribution of each regional unit in the pool, the hydrolysis-dominant zone, acid-producing zone, and buffer zone are spatially organized to generate a spatial distribution map of microbial functional zones.

[0100] In this embodiment, the spatial distribution map of microbial functional zones is a regional functional distribution map formed by marking and organizing the distribution of the hydrolysis-dominant zone, acid-producing zone and buffer zone corresponding to each regional unit in the hydrolysis acidification tank in the spatial location of the tank.

[0101] In this embodiment, the imbalance characterization generation module includes:

[0102] Based on the spatial distribution map of microbial functional zones, the functional type of each regional unit in the pool is extracted, and the combination of adjacent regional units where the functional type changes is identified, generating the corresponding set of functional boundary regions.

[0103] Regional functional type is the functional category identifier of each regional unit in the spatial distribution map of microbial functional zones, corresponding to the hydrolysis-dominant zone, acid-producing-dominant zone, or buffer zone.

[0104] For each set of functional boundary regions, extract the boundary center position corresponding to each set of functional boundary regions to generate the functional boundary position;

[0105] Based on the changes in the boundary center position of each functional boundary region set at two consecutive acquisition times, the boundary migration path of each functional boundary region set from the previous acquisition time to the next acquisition time is extracted, and the boundary migration direction is generated.

[0106] The boundary migration direction is the direction in which the position of the functional boundary shifts from the spatial position of the previous pool to the spatial position of the next pool between two consecutive acquisition times;

[0107] Based on the boundary center position offset of each functional boundary region set at two consecutive acquisition times, the boundary displacement degree of each functional boundary region set in the corresponding acquisition time period is extracted to generate the boundary migration amplitude.

[0108] Based on the adjacency relationship of each regional unit, the continuous distribution length, continuous distribution range and cross-regional connection status between regional units of the same functional type are extracted to generate regional functional continuity;

[0109] The continuous distribution length is the length covered by the continuous arrangement of regional units of the same functional type along the spatial position of the pool. The continuous distribution range is the area covered by the continuous distribution of regional units of the same functional type in the spatial position of the pool. The cross-regional connection status is whether a continuous transition and functional connection is formed between adjacent different functional types in the spatial position of the pool.

[0110] Regional functional continuity is generated by combining continuous distribution length, continuous distribution range, and cross-regional connection status. Specifically, the continuous distribution length is first obtained based on the continuous arrangement of regional units of the same functional type in the spatial position of the pool. Then, the continuous distribution range is obtained based on the coverage of regional units of the same functional type in the length, width, and depth directions of the pool. The cross-regional connection status is obtained based on whether a stable spatial contact and functional succession relationship is formed between adjacent different regional functional types. The continuous distribution length, continuous distribution range, and cross-regional connection status are converted into corresponding continuity characterization values ​​and weighted summed to generate regional functional continuity.

[0111] The boundary migration direction, boundary migration magnitude, and regional functional continuity are correlated accordingly, and the functional boundary regions that continuously migrate towards the same functional area and whose boundary migration magnitude exceeds the preset boundary drift threshold are identified as functional boundary drift regions.

[0112] The set of functional boundary regions where adjacent regional units simultaneously possess two types of regional functions and where the continuity of regional functions decreases is identified as functional overlap regions.

[0113] A set of functional boundary regions where the continuity of regional functions is interrupted and adjacent regional units cannot form a functional connection is identified as a functional missing region.

[0114] The interruption of regional functional continuity and the inability of adjacent regional units to form a regional functional connection occurs at a certain functional boundary position, where the continuous distribution of the same regional functional type is interrupted in the middle, and the adjacent regional units on both sides of the interruption position cannot form a normal transition and connection relationship between the hydrolysis-dominant region, the acid-producing-dominant region, and the buffer receiving region.

[0115] The functional boundary drift regions, functional overlap regions, and functional loss regions are summarized and organized to generate a microbial functional region imbalance characterization set.

[0116] In this embodiment, the water area construction module includes:

[0117] Read the spatial location of each functional boundary drift region, functional overlap region, and functional missing region in the microbial functional region imbalance characterization set, and extract the set of regional units corresponding to the spatial location of the pool to generate an imbalanced regional unit set;

[0118] Based on the set of unbalanced regional units, combined with the flow data of each water distribution branch and the spatial location of the pool corresponding to each regional unit, the water distribution arrival relationship of each water distribution branch to each regional unit is determined, the coverage of each regional unit receiving the input from the water distribution branch at the corresponding collection time is statistically analyzed, and the water distribution coverage status is generated.

[0119] Water distribution arrival relationship refers to the correspondence between the sewage flow output from each water distribution branch and the spatial location of each area unit in the pool. Coverage status refers to whether each area unit receives water distribution branch input at the corresponding collection time and the distribution of which water distribution branch inputs are received.

[0120] For each regional unit in the set of unbalanced regional units, based on the distribution difference of the flow data of each water distribution branch in the spatial position of the pool at the corresponding collection time, the changes in the concentrated position of water distribution and the changes in the deviation position of water distribution relative to its adjacent regional units are extracted to generate the water distribution offset state.

[0121] The change in the concentrated water distribution position refers to the movement of the main area of ​​action corresponding to the water distribution input in the pool space relative to the previous acquisition time. The change in the deviation position of the water distribution position refers to the deviation of the water distribution input in the pool space relative to the target area of ​​action and its transfer to other area units.

[0122] For each regional unit in the set of unbalanced regional units, the flow data of each corresponding water distribution branch is correlated with the substrate input intensity of each regional unit. The substrate input continuity after receiving water distribution input and the water distribution transfer connection between adjacent regional units are extracted to generate the water distribution acceptance status.

[0123] Substrate input continuity refers to whether the substrate input formed after a certain area unit receives water distribution input continues to be maintained and passed on to subsequent area units. Water distribution transfer connection between adjacent area units refers to whether the water distribution action between adjacent area units forms a continuous transfer and continuous connection.

[0124] The water distribution coverage state, water distribution offset state, and water distribution acceptance state are organized according to the same regional unit to form a combination of water distribution states corresponding to each regional unit, thereby generating a water distribution distribution characterization.

[0125] Water distribution coverage status refers to the coverage data of sewage input from each water distribution branch received by each regional unit at the corresponding acquisition time. It is used to characterize whether each regional unit is affected by water distribution and how many water distribution branches it is affected by. Water distribution offset status refers to the data on the changes in the concentration position and deviation position of the corresponding water distribution input in the pool space of each regional unit. It is used to characterize whether the center of water distribution deviates from the target regional unit or shifts to an adjacent regional unit. Water distribution connection status refers to the data on the continuity of substrate input formed after each regional unit receives water distribution input and the water distribution transfer connection between adjacent regional units. It is used to characterize whether the water distribution effect can form continuous transfer and functional connection between regional units.

[0126] Based on the water distribution characterization, regional units with insufficient water distribution coverage and interrupted water distribution reception are identified as functional compensation candidate regions. Regional units with water distribution offset extending towards the interior of the functional boundary drift region are identified as boundary correction candidate regions. Regional units with overlapping water distribution coverage and intersecting water distribution offset are identified as distribution adjustment candidate regions.

[0127] Insufficient water distribution coverage and interrupted water distribution reception state means that the number of water distribution branch inputs received by the target area unit at the corresponding acquisition time is less than the number of water distribution inputs required for its functional compensation, and the water distribution effect received by the target area unit cannot continue to be continuously transmitted and received to the adjacent area units. The water distribution offset state extends towards the interior of the functional boundary drift area, meaning that the main action area of ​​the water distribution input in the pool space position is not kept in the original target area unit, but continues to shift towards the corresponding area unit inside the functional boundary drift area along the functional boundary migration direction. The overlapping water distribution coverage state and the intersecting water distribution offset state means that two or more water distribution branches form repeated coverage on the same area unit or adjacent area units, and at the same time, the offset paths of the main action areas corresponding to each water distribution branch intersect or intersect in the pool space position.

[0128] The candidate regions for functional compensation, boundary correction, and distribution adjustment are matched with the microbial functional zone imbalance characterization set to determine the target water distribution induction region corresponding to the microbial functional zone imbalance characterization set.

[0129] In this embodiment, the reaction domain construction and coupling relationship establishment module includes:

[0130] Read the regional units corresponding to the functional boundary drift areas, functional overlap areas and functional loss areas in the microbial functional zone imbalance characterization set, and extract the distribution characteristics of the distribution water area, acidification promotion intensity and sludge enrichment intensity of the regional units to generate a set of reaction analysis regional units;

[0131] The reaction analysis unit set is a set of unit sets selected from the unit sets corresponding to the microbial functional zone imbalance characterization set, used to extract the reaction advancement state, reaction retention state, and reaction acceptance state;

[0132] For each region unit in the reaction analysis region unit set, combined with the change of the corresponding acidization propulsion intensity at continuous acquisition time, the reaction propulsion position change and reaction propulsion continuation of each region unit are extracted to generate the reaction propulsion state;

[0133] The change in reaction propulsion position refers to the movement of the main propulsion area of ​​the acidification reaction in the pool space relative to the previous acquisition time. The continuation of reaction propulsion refers to whether the acidification reaction continues to propel to the adjacent regional unit after the current regional unit is formed.

[0134] For each regional unit in the reaction analysis regional unit set, based on the distribution of the corresponding acidification propulsion intensity and sludge enrichment intensity in the spatial location of the pool, the degree of residence of the reaction in the target regional unit and the obstruction of its transmission to adjacent regional units are extracted to generate the reaction retention state.

[0135] The degree of residence within the target region unit is the continuous state in which the reaction is concentrated and maintained within the target region unit. The state of obstruction of transmission to adjacent region units is the state in which the transmission is interrupted or weakened when the reaction continues to extend from the target region unit to the adjacent region unit.

[0136] The acidification promotion intensity, sludge enrichment intensity and water distribution characteristics of each regional unit are correlated, and the reaction transmission continuity and regional function inheritance between each regional unit and adjacent regional units are extracted to generate the reaction inheritance status.

[0137] The continuity of reaction transmission refers to whether the reaction continues to expand and be transmitted between adjacent regional units. The functional succession of regions refers to whether adjacent regional units can form a continuous transition and functional succession according to the functional distribution relationship of the hydrolysis-dominant region, the buffer-receiving region, and the acid-producing-dominant region.

[0138] Organize the reaction advance state, reaction stagnation state and reaction acceptance state corresponding to the same regional unit to form the reaction state combination corresponding to each regional unit, and generate the reaction domain distribution characterization.

[0139] Based on the distribution characterization of water distribution areas, the distribution characterization of reaction areas, and the spatial distribution map of microbial functional zones, the correspondence between the water distribution location and the reaction advancement location, the correspondence between the water distribution transfer state and the reaction acceptance state, and the correspondence between the regional functional type and the reaction state combination of each regional unit are extracted to generate a set of three-domain corresponding units.

[0140] The correspondence between the regional units in the three-domain corresponding unit set is summarized and organized to establish a three-domain coupling correspondence between the distribution characterization of water area, the distribution characterization of reaction domain, and the spatial distribution map of microbial functional areas;

[0141] First, for each regional unit, the corresponding regional functional type is read from the distribution characteristics of the water distribution area, the distribution characteristics of the reaction zone, and the spatial distribution map of the microbial functional zones. Within the same regional unit, the spatial location of the pool mainly affected by the water distribution input is compared with the spatial location of the pool mainly advanced by the acidification reaction. If the two are located within the same regional unit, or within adjacent regional units with a continuous connection, then a correspondence is determined between the water distribution location and the reaction advancement location. Next, for adjacent regional units, the water distribution transmission state and the reaction connection state are compared. If the water distribution action forms a continuous transmission between adjacent regional units, and the reaction action forms a continuous connection between adjacent regional units, then the water distribution transmission state is determined. There is a correspondence between the functional type and the reaction state. Then, the combination of regional functional types and reaction states is compared. If the reaction state combination corresponding to the hydrolysis-dominant zone shows a priority of reaction advancement, the reaction state combination corresponding to the buffer zone shows a continuous reaction state, and the reaction state combination corresponding to the acid production-dominant zone shows a stable acidification advancement state, then a correspondence between the regional functional type and the reaction state combination is determined. The three types of correspondence are summarized and organized between the same regional unit and adjacent regional units to form a set of three-domain corresponding units. Based on the set of three-domain corresponding units, a three-domain coupling correspondence relationship is established between the distribution characterization of water areas, the distribution characterization of reaction domains, and the spatial distribution map of microbial functional zones.

[0142] In this embodiment, the collaborative control execution module includes:

[0143] Read the water distribution characterization, reaction domain distribution characterization and regional functional type of each regional unit in the three-domain coupling correspondence, extract the functional compensation demand and reaction acceptance demand corresponding to the target water distribution induced area, and generate a set of regional regulation demand.

[0144] For each regional unit in the set of regional regulation needs, based on the corresponding water distribution coverage status, water distribution offset status and water distribution acceptance status, determine the insufficient water distribution effect, water distribution offset correction amount and water distribution transmission compensation amount of each water distribution branch to the target water distribution induced area, and generate the branch flow regulation amount corresponding to each water distribution branch.

[0145] Based on the water distribution coverage status corresponding to the target water distribution induction area, the actual water distribution branch input coverage currently received in the target water distribution induction area is compared with the target coverage corresponding to the functional compensation requirements to determine the insufficient water distribution effect of each water distribution branch. Based on the water distribution offset status corresponding to the target water distribution induction area, the spatial deviation between the current main water distribution input area and the target water distribution induction area is compared to determine the water distribution offset correction amount corresponding to each water distribution branch. Based on the water distribution receiving status corresponding to the target water distribution induction area, the water distribution transmission connection between the current target water distribution induction area and adjacent area units is compared with the target transmission required for continuous functional receiving to determine the water distribution transmission compensation amount corresponding to each water distribution branch. Then, the insufficient water distribution effect, water distribution offset correction amount, and water distribution transmission compensation amount corresponding to each water distribution branch are summarized to generate the branch flow regulation amount corresponding to each water distribution branch.

[0146] Based on the branch flow regulation amount corresponding to each regional unit and the distribution order of each regional unit in the pool space in the set of regional control needs, the sequential action time of each water distribution branch on the target water distribution induction area is determined, and the time-sharing water distribution sequence is generated.

[0147] The time-sharing water distribution sequence is the time sequence in which each water distribution branch performs water distribution on the target water distribution and induction area in different time periods according to a predetermined order.

[0148] Based on the branch flow regulation amount, time-sharing water distribution sequence, and pool spatial location coverage of the target water distribution induction area, the flow distribution share of each water distribution branch in different target water distribution induction areas is determined, and the zoned water distribution ratio is generated.

[0149] For each regional unit in the set of regional regulation needs, based on the corresponding reaction advancement state, reaction retention state and reaction acceptance state, and combined with the distribution order of regional functional types in the spatial location of the pool, the sequence of reaction advancement, reaction slow release and reaction acceptance compensation for each regional unit is determined, and the reaction regulation sequence is generated.

[0150] First, the reaction propulsion state, reaction retention state, reaction acceptance state, regional functional type, and pool spatial location corresponding to each regional unit in the regional regulation demand set are read to generate a basic dataset for regional reaction regulation. Then, the regional units in the basic dataset are arranged sequentially according to their pool spatial locations to generate a regional spatial distribution sequence set. Based on this sequence set, regional units corresponding to restricted propulsion states are selected as reaction propulsion regulation regions, generating a set of reaction propulsion regulation regions. After obtaining the reaction propulsion regulation region set, regional units corresponding to reaction retention states where the reaction retention level exceeds a preset retention threshold are selected as reaction slow-release regulation regions, generating a set of reaction slow-release regulation regions. Finally, based on the regional spatial distribution sequence set, reaction transmission connections corresponding to reaction acceptance states are selected... Regional units where the continuity of operations is interrupted or the regional functional acceptance is mismatched are identified as reaction acceptance compensation regions, generating a reaction acceptance compensation region set. Then, the reaction propulsion regulation region set, reaction slow-release regulation region set, and reaction acceptance compensation region set are organized according to the distribution order of regional functional types and pool spatial locations. For reaction propulsion regulation regions located upstream and belonging to the hydrolysis-dominant zone, reaction propulsion is prioritized; for reaction acceptance compensation regions located in the middle and belonging to the buffer zone, reaction acceptance compensation is subsequently arranged; and for regional units located downstream and experiencing reaction stagnation, reaction slow-release is arranged, generating a regional regulation sequence set. Based on the regional regulation sequence set, the corresponding reaction propulsion execution period, reaction acceptance compensation execution period, and reaction slow-release execution period for each regional unit are arranged sequentially to generate a reaction regulation time sequence.

[0151] The branch flow regulation amount, time-sharing water distribution sequence, zone water distribution ratio and reaction regulation sequence are organized according to the same target water distribution induction area to form a water distribution-reaction coordinated regulation sequence.

[0152] Based on the water distribution-reaction synergistic regulation sequence, the output flow and duration of each water distribution branch are adjusted, and the reaction advancement process corresponding to the target water distribution induction area is synchronously regulated according to the reaction regulation sequence, so as to drive the spatial self-reconstruction of the microbial functional zone.

[0153] After implementing the hydrolysis-acidification tank operation adjustment according to the water distribution-reaction synergistic control sequence, continuous collection of operational status data and updating of the spatial distribution map of microbial functional zones, the imbalance characterization set of microbial functional zones, the distribution characterization of water distribution areas, and the distribution characterization of reaction domains; checking whether the hydrolysis-dominant zone, buffer zone, and acid-producing-dominant zone in the updated spatial distribution map of microbial functional zones have re-established a stable distribution; checking whether the functional boundary drift areas, functional overlap areas, and functional deficiency areas in the updated imbalance characterization set of microbial functional zones have been eliminated or reduced; and checking whether the updated distribution characterization of water distribution areas and the distribution characterization of reaction domains can be consistent with the regional functional types. The system should check whether the updated three-domain coupling correspondence remains continuous and stable. When the spatial distribution map of microbial functional zones remains stable over multiple consecutive collection cycles, the imbalance characterization set of microbial functional zones no longer adds new imbalance regions, the distribution characterization of water areas and the distribution characterization of reaction domains can continuously match the functional types of the regions, and the three-domain coupling correspondence remains continuous and consistent, it is determined that the spatial self-reconstruction of microbial functional zones has been completed. If new functional boundary drift regions, functional overlap regions, or functional missing regions appear again in any collection cycle, or the three-domain coupling correspondence is interrupted again, it is determined that the spatial self-reconstruction has not been completed, and the cyclic correction continues.

[0154] In this embodiment, the functional compensation requirement is the additional water distribution and substrate input required by the target water distribution induction area to restore the corresponding area's functional type, and the reaction acceptance requirement is the reaction connection requirement that the target water distribution induction area must meet to restore the continuous reaction transmission and functional acceptance relationship between adjacent area units.

[0155] In this embodiment, the closed-loop update and correction module includes:

[0156] After the hydrolysis acidification tank is regulated and adjusted according to the water distribution-reaction synergistic control sequence, the operating status data of the hydrolysis acidification tank is continuously collected and preprocessed to generate an updated standardized operating status dataset.

[0157] Based on the updated standardized operational status dataset, the substrate input intensity, acidification propulsion intensity and sludge enrichment intensity corresponding to each regional unit were re-extracted, and the spatial distribution map of microbial functional zones was updated.

[0158] Based on the updated spatial distribution map of microbial functional regions, functional boundary drift regions, functional overlap regions, and functional loss regions are re-identified to generate an updated microbial functional region imbalance characterization set.

[0159] Based on the updated characterization set of microbial functional zone imbalance, the characterization of water distribution and reaction domain distribution were updated;

[0160] Based on the updated water distribution characterization, updated reaction domain distribution characterization, and updated microbial functional zone spatial distribution map, an updated three-domain coupling correspondence was established, and an updated water distribution-reaction synergistic regulation sequence was generated.

[0161] Based on the updated water distribution-reaction synergistic regulation sequence, the operation and regulation process of the hydrolysis acidification tank is cyclically corrected to achieve adaptive synergistic regulation of the hydrolysis acidification tank.

[0162] Example 1: To verify the feasibility of this invention in practice, it was applied to the operation and control of a hydrolysis acidification tank in a riverside industrial wastewater treatment plant. This wastewater treatment plant is responsible for the pretreatment of mixed wastewater from the industrial park. The influent sources are complex, including both production wastewater with significant fluctuations in organic load and auxiliary drainage with frequent changes in flow rate. Due to the rapid changes in influent composition, the original operation relied mainly on a fixed water distribution method and manual experience-based adjustments. This led to situations where different areas within the hydrolysis acidification tank experienced concentrated substrate inflow, discontinuous acidification progress in some areas, and weakened function in intermediate receiving areas. This further manifested as uneven reaction states in different spatial locations within the tank, difficulty in achieving continuous coordination between water distribution and reaction progression in some areas, and insufficient stability in the distribution of microbial functional zones. When operators adjust individual water distribution branches based solely on influent changes or local monitoring information, while short-term corrections to local conditions are possible, it is difficult to restore the continuous transition between the hydrolysis-dominant zone, buffer receiving zone, and acid-producing-dominant zone as a whole. Therefore, under continuous operation, problems such as functional boundary drift, functional overlap, and functional loss are still prone to occur.

[0163] In this scenario, operational status data acquisition devices are first deployed at the inlet of the hydrolysis acidification tank and multiple monitoring locations within the tank to continuously acquire data on influent chemical oxygen demand (COD), influent flow rate, oxidation-reduction potential (ORP), volatile fatty acid concentration, sludge concentration, and flow rate of each water distribution branch. The collected data is then input into the system of this invention. The system first performs time synchronization, anomaly removal, missing data completion, and normalization on the operational status data to form a standardized operational status dataset. Subsequently, the tank is divided into multiple regional units according to its spatial location. For each regional unit, substrate input intensity, acidification propulsion intensity, and sludge enrichment intensity are extracted to construct a set of regional functional characteristics. The system also identifies the hydrolysis-dominant zone, acidification-dominant zone, and buffer zone, generating a spatial distribution map of microbial functional zones. Operators can intuitively see the current functional type of each regional unit within the tank and the distribution status between different functional zones through the system interface. Next, the system further identifies functional boundary drift regions, functional overlap regions, and functional deficiency regions, generating a set of microbial functional zone imbalance characterization sets. Based on this, it constructs distribution characterizations of water distribution areas and reaction domains, establishing a three-domain coupling correspondence between these characterizations and the spatial distribution map of microbial functional zones. According to this three-domain coupling correspondence, the system automatically forms a water distribution-reaction synergistic regulation sequence, coordinating the output flow rate, action time, and regional distribution of each water distribution branch. Simultaneously, it adjusts the distribution in sync with the reaction propagation process within the tank, gradually returning the previously deviated water distribution effect to the target water distribution induction area. This re-establishes a continuous connection between the reaction propagation state and the regional functional type, promoting a stable spatial distribution of microbial functional zones. As operation continues, the system continues to collect the latest operational data, update the three-domain coupling correspondence, and cyclically correct the water distribution-reaction synergistic regulation sequence, ensuring the entire hydrolysis acidification tank is always in a state of dynamic adjustment and continuous correction.

[0164] To verify the performance of the invention in practice, comparative experiments were conducted.

[0165] Table 1 Comparison of Overall Operational Performance of Hydrolysis Acidification Tanks

[0166] Comparison Methods Functional boundary stability retention rate Frequency of microbial functional zone imbalance Matching degree between water distribution function and reaction propulsion Continuous stable operation duration Load fluctuation recovery time Traditional fixed water distribution regulation method 71.2% 9 times 68.1% 23.0 hours 6.8 hours Method of the present invention 91.4% 2 times 89.2% 38.4 hours 2.6 hours

[0167] As can be seen from Table 1, the method of the present invention is superior to the traditional fixed water distribution regulation method in terms of overall operating performance.

[0168] Regarding the stability retention rate of functional boundaries, the traditional method achieves only 71.2%, while the method of this invention reaches 91.4%, a significant improvement. This indicates that after adopting this invention, the spatial distribution relationship between the hydrolysis-dominant zone, the buffer zone, and the acid-producing-dominant zone is more stable, and the boundaries between different functional zones within the pool are less prone to frequent drift, thus maintaining a more continuous and reasonable regional division of labor. Compared to traditional methods that mainly rely on fixed water distribution methods and local empirical adjustments, this invention can perform overall identification and continuous correction based on the spatial distribution map of microbial functional zones, thus being more conducive to maintaining a continuous transition relationship between functional zones.

[0169] In terms of the frequency of microbial functional zone imbalances, the traditional fixed water distribution regulation method reached 9 times, while the method of this invention only occurred 2 times. This indicates that the present invention can effectively suppress the frequency of functional boundary drift, functional overlap, and functional loss. This decrease in the index is directly significant because it shows that the present invention does not passively remedy imbalances after they occur, but rather can promptly detect imbalance trends through the microbial functional zone imbalance characterization set and combine it with the distribution characterization of water distribution area and reaction domain distribution for coordinated regulation, thereby controlling the imbalance within a smaller range. It is precisely because of this that the present invention exhibits stronger stable control capabilities in actual operation.

[0170] In terms of the matching degree between water distribution and reaction advancement, the traditional method achieves only 68.1%, while the method of this invention reaches 89.2%. This result indicates that the present invention establishes a closer correspondence between water distribution regulation and reaction regulation. A common problem in traditional methods is that although water input reaches a certain area, the reaction advancement state in that area does not improve synchronously, or the area requiring reaction advancement does not receive sufficient water distribution support, resulting in a significant mismatch between water distribution and reaction state. The present invention establishes a three-domain coupled correspondence between the distribution characterization of water distribution areas, the distribution characterization of reaction domains, and the spatial distribution map of microbial functional zones, thus maintaining a higher consistency between the location of water distribution, the location of reaction advancement, and the functional type of the region, thereby significantly improving the matching degree.

[0171] In terms of both continuous stable operation time and load fluctuation recovery time, this invention also demonstrates significant advantages. The continuous stable operation time has increased from 23.0 hours using traditional methods to 38.4 hours, indicating that this invention enables the hydrolysis acidification tank to maintain stable functional zone distribution and continuous reaction processes for a longer period. The load fluctuation recovery time has been shortened from 6.8 hours to 2.6 hours, demonstrating that when influent concentration and flow rate fluctuate, this invention can more quickly complete the coordinated regulation of water distribution and reaction, allowing the system to return to a stable operating state as soon as possible. The fundamental reason for this improvement lies in the fact that this invention does not adjust a single parameter, but rather generates a coordinated water distribution-reaction regulation sequence based on the functional compensation and reaction acceptance needs of the target water distribution induction zone, thereby achieving overall correction for the spatial self-reconstruction of microbial functional zones.

[0172] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The adaptive-based hydrolysis-acidification water distribution-reaction collaborative control system for sewage treatment according to claim 1, characterized in that, The closed-loop update and correction module includes: After the hydrolysis acidification tank is regulated and adjusted according to the water distribution-reaction synergistic control sequence, the operating status data of the hydrolysis acidification tank is continuously collected and preprocessed to generate an updated standardized operating status dataset. Based on the updated standardized operational status dataset, the substrate input intensity, acidification propulsion intensity and sludge enrichment intensity corresponding to each regional unit were re-extracted, and the spatial distribution map of microbial functional zones was updated. Based on the updated spatial distribution map of microbial functional regions, functional boundary drift regions, functional overlap regions, and functional loss regions are re-identified to generate an updated microbial functional region imbalance characterization set. Based on the updated characterization set of microbial functional zone imbalance, the characterization of water distribution and reaction domain distribution were updated; Based on the updated water distribution characterization, updated reaction domain distribution characterization, and updated microbial functional zone spatial distribution map, an updated three-domain coupling correspondence was established, and an updated water distribution-reaction synergistic regulation sequence was generated. Based on the updated water distribution-reaction synergistic regulation sequence, the operation and regulation process of the hydrolysis acidification tank is cyclically corrected to achieve adaptive synergistic regulation of the hydrolysis acidification tank.
