Description

Technical Field

[0001] This application relates to the field of inland river management, and in particular to a method, equipment, and storage medium for the coordinated control of urban inland river management equipment. Background Technology

[0002] With increasing demands for water quality improvement, urban river management typically employs a multi-pronged approach involving various treatment devices, such as aeration equipment, microbial inoculation equipment, filtration equipment, flocculant dosing equipment, sediment conditioner dosing equipment, and pump-pipe circulation devices. These devices comprehensively improve river water quality through three pathways: hydrodynamics, chemical reactions, and biological metabolism.

[0003] Existing urban river management methods mainly focus on system-level and algorithm-level optimization, such as water dispatching algorithms, monitoring networks, subsystem coordination, and facility control. While numerous technical solutions exist for making overall decisions on the start-up and shutdown timing and flow allocation of management equipment through dispatching models and optimization algorithms, existing methods lack a systematic, machine-manageable set of avoidance rules to address the process-level coupling interference caused by hydrodynamic, chemical, and biological metabolic interactions when multiple management devices operate simultaneously in urban rivers, and the resulting equipment-level avoidance requirements. Furthermore, there is a lack of supporting engineering solutions for equipment-level collaborative decision-making, such as the selection of multiple water intake and drainage topologies under different pollution distribution scenarios, conflict resolution between avoidance rules and water intake / drainage topology switching when triggered simultaneously, and auxiliary identification using multi-source identification data. Therefore, process interference is prone to occur when multiple management devices operate simultaneously, making it difficult to simultaneously achieve both comprehensive management coverage and water quality safety. Summary of the Invention

[0004] To address the problems of existing urban river management methods lacking systematic avoidance rules for process-level coupling interference of multiple management devices, lacking supporting engineering solutions for the selection of water intake and drainage topology and the mediation of rule conflicts, and causing process interference to easily occur when multiple management devices are running simultaneously, making it difficult to balance management coverage and water quality safety, this application provides a collaborative control method for urban river management devices, computer equipment, and computer-readable storage medium.

[0005] Firstly, this application provides a method for coordinated control of urban inland river management equipment, which adopts the following technical solution: A method for coordinated control of urban inland river management equipment includes: S1. Construct a physical and chemical coupling constraint library for process equipment. The physical and chemical coupling constraint library for process equipment stores equipment-level avoidance rules between multiple governance equipment. Each equipment-level avoidance rule adopts a three-element structure of equipment pair, coupling mechanism and avoidance condition. Equipment pair includes at least two multiple governance equipment that interact due to coupling mechanism. Avoidance condition includes the triggering conditions and limiting actions that the equipment pair needs to satisfy. S2. Monitor the water quality of urban rivers and generate a spatial-temporal water quality field; S3. Identify the centroid of pollution distribution and the dominant pollution type based on the spatial-temporal water quality field; S4. Based on the physical and chemical coupling constraint library of process equipment, the centroid of pollution distribution, and the dominant pollution type, determine the avoidance plan for multiple treatment equipment and the intake and drainage topology of the pump and pipe circulation device in the multiple treatment equipment; S5. Drive the operation of the multi-treatment equipment according to the avoidance plan, drive the operation of the pump pipe circulation device according to the water intake and drainage topology mode, and adjust the avoidance plan and the water intake and drainage topology mode according to the evolution feedback of the spatial-temporal water quality field.

[0006] By adopting the above technical solution, the three-element structure of the physical-chemical coupling constraint library of process equipment formalizes the process-level avoidance relationship between multiple treatment devices into a machine-readable rule set. This enables multiple treatment devices to make unified decisions that take into account both equipment avoidance and water intake / discharge topology when coordinating and controlling the system. By jointly outputting the equipment-level avoidance planning and the water intake / discharge topology mode of the pump and pipe circulation device, multiple treatment devices can avoid the three types of coupling interference of hydrodynamics, chemical reaction, and biological metabolism under different pollution distribution scenarios. They can also achieve targeted water flow organization through dynamic adjustment of water intake / discharge paths, thereby improving water quality safety while ensuring treatment coverage.

[0007] Optionally, the equipment-level avoidance rules in the process equipment physicochemical coupling constraint library are divided into the following three categories according to the type of coupling mechanism: hydrodynamic coupling rules, which limit the avoidance conditions between multiple treatment devices caused by the interaction of water flow fields. Hydrodynamic coupling rules include at least: in response to the aeration equipment being in operation, the pump pipe circulation device is prohibited from taking water within a preset isolation distance downstream of the aeration equipment; chemical reaction coupling rules, which limit the avoidance conditions between multiple treatment devices caused by the chemical reaction interaction of added agents. Chemical reaction coupling rules include at least: in response to the bacteria feeding equipment being in operation, the filtration equipment is prohibited from starting within a preset decay time after the start of operation of the bacteria feeding equipment; biological metabolism coupling rules, which limit the avoidance conditions between multiple treatment devices caused by the interaction of biological metabolic processes. Biological metabolism coupling rules include at least: in response to the submerged plants arranged in urban rivers being in a preset peak period of photosynthesis, the operating intensity of the aeration equipment is reduced to a preset intensity ratio.

[0008] By adopting the above technical solution, the equipment-level avoidance rules are classified into three mechanisms: hydrodynamic, chemical reaction, and biological metabolism. This gives the rules in the constraint library a clear process mechanism attribution, making it easier to expand, maintain, and deploy the constraint library in an engineering manner according to the mechanism type.

[0009] Optionally, hydrodynamic coupling rules also include: in response to the fountain aeration equipment being in operation, the pump pipe circulation device is prohibited from taking water within a preset distance downwind of the fountain aeration equipment; in response to the pump pipe circulation device containing multiple circulation pumps and multiple circulation pumps being in operation simultaneously, the distance between the water intakes of any two circulation pumps is not less than a preset pump spacing; chemical reaction coupling rules also include: in response to the flocculant dosing equipment being in operation, the pump pipe circulation device is prohibited from operating within a preset flocculation isolation distance downstream of the flocculant dosing equipment; in response to the sediment conditioner dosing equipment having completed dosing and the time remaining after dosing not exceeding a preset diffusion time, the water flow disturbance intensity in the area where submerged plants are located is prohibited from exceeding a preset disturbance threshold; biological metabolism coupling rules also include: in response to the compound microbial preparations added by the inoculant dosing equipment not exceeding a preset inactivation protection time after dosing, the dosing disinfection equipment is prohibited from operating; in response to the identification of a high-density aquatic animal activity area, the strong disturbance aeration equipment is prohibited from operating within a preset safe distance of the high-density aquatic animal activity area.

[0010] By adopting the above technical solutions, multiple specific equipment-level avoidance rules are given for the three types of mechanism rules: hydrodynamic, chemical reaction, and biological metabolism. This improves the coverage and completeness of the constraint library, and provides sufficient rule support for the collaborative decision-making of multiple treatment devices under different equipment pair combinations.

[0011] Optionally, the pump-pipe circulation device includes at least two sets of water intake and drainage interfaces and a bidirectional switching valve group located between the at least two sets of water intake and drainage interfaces. The pump-pipe circulation device has a water intake position and a drainage position. The water intake and drainage topology includes the following four modes: upstream and downstream longitudinal circulation mode, in which the water intake position is located at the upstream end of the urban river and the drainage position is located at the downstream end of the urban river, or the water intake position is located at the downstream end of the urban river and the drainage position is located at the upstream end of the urban river; lateral short circulation mode, in which the water intake position and the drainage position are located on the same bank of the urban river, and the distance between the water intake position and the drainage position is less than the preset short circulation distance; multi-point decentralized circulation mode, in which at least two sets of water intake and drainage interfaces operate synchronously at at least three segment positions in the urban river; and static isolation circulation mode, in which the pump-pipe circulation device only operates in the preset isolation segment in the urban river where the pollution distribution centroid is located, and the two ends of the preset isolation segment are isolated from the other segments of the urban river by the bidirectional switching valve group.

[0012] By adopting the above technical solution, four water intake and drainage topology modes are formed by using bidirectional switching valve groups in conjunction with at least two sets of water intake and drainage interfaces. This enables limited hardware configuration to cover four water flow organization forms: longitudinal circulation, lateral short circulation, multi-point dispersion, and static isolation, adapting to different pollution distribution scenarios.

[0013] Optionally, the selection of the water intake and drainage topology mode shall be performed according to the following mapping rules: In response to the dominant pollution type being ammonia nitrogen and the pollution distribution centroid being located in the middle section of the urban river, the upstream and downstream longitudinal circulation mode shall be selected; in response to the dominant pollution type being turbidity and the pollution distribution centroid being biased towards one bank of the urban river, the lateral short circulation mode shall be selected; in response to the identification of multiple pollution distribution centroids scattered throughout the urban river in the spatial-temporal water quality field, the multi-point dispersed circulation mode shall be selected; in response to the identification of a sudden pollution event in the spatial-temporal water quality field and the pollution distribution centroid being surrounded by a preset isolation segment, the static isolation circulation mode shall be selected; in response to the dominant pollution type being neither ammonia nitrogen nor turbidity, or the identification of no multiple pollution distribution centroids scattered throughout the spatial-temporal water quality field and no sudden pollution event, the upstream and downstream longitudinal circulation mode shall be selected as the default mode.

[0014] By adopting the above technical solution, a clear mapping rule from water quality characteristics to water intake and drainage topology is established based on the dual criteria of dominant pollution type and pollution distribution centroid location. The default mode is used as a fallback to ensure that the algorithm can output a definite topology decision under any pollution scenario.

[0015] Optionally, the process equipment physicochemical coupling constraint library is organized into the following three-layer structure: a basic layer, which stores equipment-level avoidance rules independent of the local characteristics of urban inland rivers; an optimization layer, which stores equipment-level avoidance rules obtained by calibrating the equipment-level avoidance rules in the basic layer based on the local operating data of urban inland rivers; and an emergency layer, which stores equipment-level avoidance rules triggered in response to abnormal water quality events. Each equipment-level avoidance rule in the process equipment physicochemical coupling constraint library is divided into hard avoidance rules and soft avoidance rules according to the reversibility of the coupling mechanism. Hard avoidance rules correspond to equipment-level avoidance rules with a physicochemically irreversible coupling mechanism, while soft avoidance rules correspond to equipment-level avoidance rules with a physicochemically reversible coupling mechanism.

[0016] By adopting the above technical solution, the constraint library is organized in a three-layer structure of basic layer, optimization layer and emergency layer, so that universal rules, local calibration rules and emergency rules can be clearly managed in layers; hard and soft avoidance rules are distinguished according to physical and chemical reversibility, providing a graded basis for subsequent conflict mediation and coverage downgrading.

[0017] Optionally, when determining the avoidance planning and water intake / discharge topology pattern in S4, sub-steps S41-S42 are also included: S41. In response to multiple equipment-level avoidance rules and water intake / drainage topology modes being triggered simultaneously and conflicting in the physical-chemical coupling constraint library of process equipment, the conflict between the multiple equipment-level avoidance rules and water intake / drainage topology modes is mediated according to a preset priority table. In the preset priority table, the priority of hard avoidance rules is higher than the priority of soft avoidance rules, the priority of hard avoidance rules is higher than the priority of water intake / drainage topology modes, and the priority of water intake / drainage topology modes is higher than the priority of soft avoidance rules.

[0018] S42. After S41 is executed, calculate the governance coverage rate of the multi-governance devices when running according to the avoidance plan. In response to the governance coverage rate being lower than the preset coverage threshold, allow the soft avoidance rule that is still in the triggered state after S41 to be downgraded and executed, so that the part of the multi-governance devices that is limited by the soft avoidance rule enters the limited operation state.

[0019] By adopting the above technical solution, a complete ternary partial order of hard avoidance rules, water intake and drainage topology mode, and soft avoidance rules is used to mediate conventional conflicts. Then, the governance coverage threshold is used as the trigger condition for further downgrading of soft rules, so as to achieve collaborative decision-making at two levels: conventional mediation and coverage feedback, thereby maintaining governance coverage while ensuring process safety.

[0020] Optionally, at least two types of submerged plants are arranged in the urban river. These at least two types of submerged plants are selected from Vallisneria natans, Hydrilla verticillata, Elodea nuttallii, and Ceratophyllum demersum. The identification of the pollution distribution centroid and dominant pollution type in S3 also includes auxiliary identification based on submerged plant habitat signals. This auxiliary identification based on submerged plant habitat signals includes substeps S31-S33: S31. Monitor at least two morphological indicators of submerged plants, including at least two of the following: leaf moisture, root growth status, and biomass per unit area.

[0021] S32. Based on morphological indicators and preset pollution stress response mapping rules, identify the local distribution characteristics of the pollution distribution centroid in the areas where at least two submerged plants are located, and identify the dominant pollution type in the local mapping area corresponding to the local distribution characteristics.

[0022] S33. The local distribution characteristics, the dominant pollution type of the local mapping area, and the spatial-temporal water quality field obtained from water quality sensor monitoring are weighted and fused according to the preset confidence weights to generate the final identification results of the pollution distribution centroid and the dominant pollution type.

[0023] By adopting the above technical solution, the habitat signal of submerged plants is introduced as an auxiliary dimension for pollution identification. It is then fused with the monitoring data based on water quality sensors through pre-set weights to expand the identification sources of the pollution distribution centroid and the dominant pollution type, thereby improving the robustness of the identification results when the water quality sensor fails locally or has insufficient accuracy.

[0024] Optionally, the aeration equipment includes at least one of fountain aeration equipment, jet aeration equipment, and micro / nano aeration equipment.

[0025] By adopting the above technical solutions, the specific implementation form of the aeration equipment can be flexibly selected according to the water depth, river width and landscape requirements of the urban river, thus expanding the applicability of aeration rules in the constraint library under different implementation forms.

[0026] Optionally, the multi-treatment equipment also includes at least one of an MBBR reactor, a biological contact oxidation reactor, and an enhanced wastewater treatment device, wherein the MBBR reactor, the biological contact oxidation reactor, and the enhanced wastewater treatment device are integrated as members of the multi-treatment equipment into the equipment pair management of the process equipment physicochemical coupling constraint library.

[0027] By adopting the above technical solutions, the coverage of multiple treatment devices is expanded, enabling the constraint library to include two types of additional treatment devices: water biochemical purification and river pollution interception, thereby enhancing the applicability of the method in complex treatment scenarios.

[0028] Optionally, the filtration equipment includes a bypass biological filtration system located in a bypass channel of an urban river.

[0029] By adopting the above technical solution, the filtration equipment is implemented in an engineering manner using bypass biological filtration, which reduces the disturbance of the filtration equipment to the main water flow of the urban river and improves the process compatibility of the filtration equipment with other treatment equipment.

[0030] Optionally, the aquatic animals arranged in the high-density aquatic animal activity area include at least one of freshwater mussels, snails, shrimp, and silver carp.

[0031] By adopting the above technical solutions, high-density activity areas of aquatic animals are defined by the combination of benthic, filter-feeding, and small omnivorous aquatic animals, providing clear species basis for the avoidance boundaries for aquatic animal protection in biological metabolism coupling rules.

[0032] Optionally, the equipment-level avoidance rules in the emergency layer include actions that respond to triggering conditions such as black and odorous water bodies, algal blooms, or sudden pollution events, as well as restrictions on the release of compound mineral emergency remediation agents into urban rivers.

[0033] By adopting the above technical solution, the administration of compound mineral emergency remediation agents is incorporated into the constraint library as an emergency layer rule, enabling the method to have emergency response capabilities in the event of black and odorous water bodies, algal blooms, and sudden pollution incidents.

[0034] Optionally, when determining the avoidance plan in S4, in response to the device-level avoidance rule triggering a multi-governance device to enter the avoidance state, another multi-governance device with a functional equivalence relationship with the multi-governance device that triggered the avoidance is selected from the preset multi-device replacement pool and activated, so that the governance coverage does not decrease due to the avoidance rule being triggered.

[0035] By adopting the above technical solution, the functionally equivalent equipment in the pool can be replaced and operated continuously, thereby reducing the impact of avoidance rule triggering on governance coverage.

[0036] Optionally, when the pump pipe circulation device is driven by the intake and drainage topology mode in S5, a minimum residence time of the intake and drainage topology mode is set. After any intake and drainage topology mode is activated, it must maintain a residence time of at least the minimum before switching to the next intake and drainage topology mode.

[0037] By adopting the above technical solution, the switching frequency of the topology mode is constrained by the minimum residence time, thereby extending the hardware life of the bidirectional switching valve group and the pump pipe circulation device and avoiding water flow oscillation.

[0038] Optionally, the switching between water intake and drainage topology modes includes a transitional control sub-step: during the switching process, the water intake and drainage interfaces corresponding to the original water intake and drainage topology mode are gradually closed according to a preset decreasing rule. After a preset transition buffer period, the water intake and drainage interfaces corresponding to the new water intake and drainage topology mode are gradually opened according to a preset increasing rule.

[0039] By adopting the above technical solutions, a smooth switching of the intake and drainage topology mode is achieved through a transition buffer period and decreasing / increasing control, thereby reducing the water flow impact during the switching instant.

[0040] Optionally, the equipment-level avoidance rules in the process equipment physical-chemical coupling constraint library are stored in a lookup table manner, and the avoidance conditions of each equipment-level avoidance rule are characterized by a binary parameter pair of distance parameter and duration parameter.

[0041] By adopting the above technical solution, the engineering expression of the coupling mechanism is simplified into a binary lookup table of distance and duration, reducing the complexity of the constraint library in the field engineering deployment.

[0042] Optionally, each multi-treatment device performs a self-calibration stator step before commissioning: measuring the process disturbance parameters of the multi-treatment device, generating localized distance and duration parameters based on the process disturbance parameters, and writing the localized distance and duration parameters into the tuning layer of the process device physicochemical coupling constraint library.

[0043] By adopting the above technical solution, the constraint library parameters can be locally calibrated through equipment operating condition self-calibration, reducing the workload of engineers in manual configuration.

[0044] Optionally, the process equipment physicochemical coupling constraint library supports online incremental learning sub-steps: periodically collect collaborative operation data of multiple treatment devices, identify coupling anomalies of device pairs that have not yet been included in the process equipment physicochemical coupling constraint library, generate candidate avoidance rules, and write them into the optimization layer of the process equipment physicochemical coupling constraint library after review.

[0045] By adopting the above technical solution, the constraint library is continuously expanded through online incremental learning, so that the constraint library is continuously improved with the operational experience of urban river management equipment.

[0046] Secondly, the computer device provided in this application adopts the following technical solution: A computer device comprising: One or more processors; Memory; One or more applications, wherein the one or more applications are stored in the memory and configured to be executed by the one or more processors, the one or more applications being configured to: Implement the above-mentioned coordinated control method for urban inland river management equipment.

[0047] Thirdly, this application provides a computer-readable storage medium that adopts the following technical solution: A computer-readable storage medium storing a computer program that can be loaded by a processor and executed as described above.

[0048] The storage medium stores at least one instruction, at least one program, a code set, or an instruction set, wherein the at least one instruction, the at least one program, the code set, or the instruction set is loaded and executed by the processor to implement the following: Such as the coordinated control method of urban inland river management equipment mentioned above.

[0049] In summary, this application includes at least one of the following beneficial technical effects: 1. By formalizing the process-level avoidance relationship between multiple treatment devices into machine-readable rules through the three-element structure of the physical-chemical coupling constraint library of process equipment, the constraint library, pollution distribution centroid and dominant pollution type jointly drive the unified decision-making of avoidance planning and water intake and drainage topology mode, so that multiple treatment devices can avoid three types of coupling interferences of hydrodynamic, chemical reaction and biological metabolism in collaborative control, thereby improving the overall response capability of urban inland river management.

[0050] 2. By using the minimum complete rule set of three types of mechanism-based avoidance rules, the dual-criteria mapping of four intake and drainage topology modes, the basic-optimization-emergency three-layer structure of the constraint library, and the ternary complete partial order of hard avoidance rules, intake and drainage topology modes, and soft avoidance rules, the equipment-level collaborative control is enhanced in terms of coverage completeness, rule maintainability, and conflict reconcilability.

[0051] 3. By expanding the identification of pollution sources through the auxiliary identification of submerged plant habitat signals and the weighted fusion of water quality sensor data, and through supporting mechanisms such as multi-device replacement pools, topology switching transitional control, constraint library engineering lookup tables, and operating condition self-calibration, synergistic optimization is achieved between ensuring treatment coverage, reducing hardware wear and tear, and engineering deployment costs.

The phrase “at least one of” when combined with a list of items refers to a single item in the list or any combination of items in the list. The phrase does not require all items listed unless explicitly defined as such.

[0058] This application provides a method for the coordinated control of urban inland river management equipment. (Refer to...) Figure 1 This method constructs a physical-chemical coupling constraint library for process equipment to store equipment-level avoidance rules between multiple treatment devices. After monitoring the water quality of urban rivers and generating a spatial-temporal water quality field, it identifies the centroid of pollution distribution and the dominant pollution type. Then, based on the constraint library, centroid, and type, it determines the avoidance plan for multiple treatment devices and the intake and drainage topology of the pump and pipe circulation device, and drives the operation of multiple treatment devices according to the avoidance plan and topology, while adjusting according to the evolution feedback of the water quality field.

[0059] To facilitate understanding, the following example illustrates the coordinated control method of urban river treatment equipment. For instance, the urban river in question is approximately 5 kilometers long, with an average depth of about 2 meters and a width of about 30 meters. The main pollution sources are upstream domestic sewage discharge and initial rainwater runoff. Typical pollution indicators include ammonia nitrogen and turbidity. Various treatment equipment, including aeration equipment, bacterial inoculation equipment, filtration equipment, flocculant dosing equipment, sediment conditioner dosing equipment, chemical disinfection equipment, and pump circulation devices, are installed in this urban river, along with planting areas for submerged plants such as *Vallisneria natans* and *Hydrilla verticillata*. The engineering parameters used in subsequent examples are typical values ​​in the field from the water treatment process design manual; specific values ​​can be adjusted according to on-site water quality conditions, equipment specifications, and river conditions. The following provides a detailed explanation of each step.

[0060] Specifically, a physical-chemical coupling constraint library for process equipment is constructed in S1. (Refer to...) Figure 2 The process equipment physicochemical coupling constraint library stores equipment-level avoidance rules between multiple governance devices. Each equipment-level avoidance rule adopts a three-element structure of equipment pair, coupling mechanism, and avoidance condition. Equipment pair includes at least two multi-governance devices that interact due to coupling mechanism, and avoidance condition includes the triggering conditions and limiting actions that the equipment pair needs to satisfy.

[0061] For example, the aeration equipment, bacteria feeding equipment, filtration equipment, flocculant feeding equipment, sediment conditioner feeding equipment, chemical disinfection equipment, and pump circulation devices deployed in the aforementioned urban rivers are all included as members of the multi-treatment equipment and are incorporated into the equipment pair management scope of the process equipment physicochemical coupling constraint library.

[0062] For example, in the physical-chemical coupling constraint library of process equipment, a typical rule is expressed in the following three-element form: the equipment pair includes aeration equipment and pump-pipe circulation device; the coupling mechanism is the interaction of water flow field, that is, when the aeration equipment is running, the dissolved oxygen concentration in a certain range downstream of it increases, and if the water intake of the pump-pipe circulation device falls into this range, it will carry away the high dissolved oxygen water, thus causing the aeration to fail; the avoidance condition is that in response to the aeration equipment being in operation, the pump-pipe circulation device does not take water within 50 meters downstream of the aeration equipment.

[0063] By formalizing the process-level coupling relationships between multiple treatment devices into a machine-readable three-element rule set, the process equipment physicochemical coupling constraint library enables collaborative decision-making on the operating status of multiple treatment devices based on the rule set when determining the avoidance planning of multiple treatment devices and the intake and drainage topology mode of the pump and pipe circulation device in subsequent S4 processes. The classification and hierarchical organization of the rules in the process equipment physicochemical coupling constraint library will be further explained below.

[0064] In some embodiments, the multi-treatment device further includes at least one of an MBBR reactor, a biological contact oxidation reactor, and an enhanced wastewater treatment device. The MBBR reactor, the biological contact oxidation reactor, and the enhanced wastewater treatment device are integrated as members of the multi-treatment device into the device pair management of the process equipment physicochemical coupling constraint library.

[0065] Taking the aforementioned implementation scenario of the coordinated control method for urban river management equipment as an example, the MBBR reactor and biological contact oxidation reactor are arranged as additional biochemical treatment equipment on the side of the river or in narrower river sections, while the sewage outlet enhanced treatment device is arranged at the outlet pipe of the sewage outlet directly entering the river. The core mechanism of the three types of additional equipment is similar to that of the original aeration equipment and bacterial dosing equipment, all of which treat pollutants in the water through biological metabolism or physicochemical processes. Therefore, they are included in the equipment pair management with the same three-element structure in the process equipment physicochemical coupling constraint library.

[0066] In some embodiments, the equipment-level avoidance rules in the process equipment physical-chemical coupling constraint library are divided into three categories according to the type of coupling mechanism: hydrodynamic coupling rules, chemical reaction coupling rules, and biological metabolism coupling rules. The three categories of rules correspond to the interactions between multiple treatment devices through three pathways: water flow field, chemical reaction, and biological metabolism.

[0067] Hydrodynamic coupling rules define avoidance conditions between multiple treatment devices caused by the interaction of water flow fields. For example, a hydrodynamic coupling rule might include, at a minimum, prohibiting the pump-pipe circulation device from drawing water within a predetermined isolation distance downstream of the aeration equipment when it is in operation. For instance, in the aforementioned urban river, when the aeration equipment is running, the dissolved oxygen concentration in a certain downstream area increases. If the pump-pipe circulation device draws water within 50 meters downstream of the aeration equipment, the high-oxygen water will be transported to the drainage point and leave the aeration area, preventing the oxygen introduced by the aeration from fully purifying the area. Therefore, in response to the aeration equipment being in operation, the pump-pipe circulation device does not draw water within 50 meters downstream of the aeration equipment.

[0068] Chemical reaction coupling rules define avoidance conditions arising from the chemical interactions between multiple treatment devices due to the addition of chemicals. For example, a chemical reaction coupling rule might include, at a minimum, prohibiting the filtration device from starting within a preset attenuation period after the start of operation of the inoculation device, in response to the inoculation device being operational. For instance, the compound microbial agent added by the inoculation device needs time to adhere to suspended solids or the surface of the filter media. If the filtration device starts within a preset attenuation period of 30 minutes after the start of operation of the inoculation device, the unattached microbial agent will be trapped by the filter media and discharged with backwashing, rendering the inoculation ineffective. Therefore, in response to the inoculation device being operational, the filtration device should not start within 30 minutes after the start of operation of the inoculation device.

[0069] Biological metabolism coupling rules define avoidance conditions between multiple treatment devices arising from interactions of biological metabolic processes. For example, such rules include at least the reduction of aeration equipment operating at a preset intensity level in response to submerged plants in urban rivers being at their preset peak photosynthetic period. For instance, submerged plants such as *Vallisneria natans* and *Hydrilla verticillata* release large amounts of oxygen during their peak photosynthetic period from 10:00 AM to 2:00 PM. If the aeration equipment operates at full intensity during this time, dissolved oxygen in the water may become supersaturated. The bubbles formed by this supersaturated dissolved oxygen will adhere to the surface of the submerged plant leaves and cause bubble damage. Therefore, in response to the submerged plants being at their peak photosynthetic period, the aeration equipment operating intensity is reduced to 60% of its full intensity.

[0070] By classifying equipment-level avoidance rules into three mechanistic categories—water flow field, chemical reaction, and biological metabolism—each rule in the process equipment physical-chemical coupling constraint library has a clear process mechanism attribution. This allows S4 to call the three types of rules according to the mechanism type when determining avoidance planning, and to make collaborative judgments based on the mechanism properties when multiple types of rules are triggered simultaneously.

[0071] In some embodiments, the aeration equipment includes at least one of fountain aeration equipment, propeller aeration equipment, and micro / nano aeration equipment. For example, fountain aeration equipment increases gas-liquid contact by lifting water and spraying it into the air before it falls, making it suitable for open river sections with landscape requirements; propeller aeration equipment promotes water flow while aerating by horizontal propulsion, making it suitable for wider river sections with poor water flow; micro / nano aeration equipment improves oxygen transfer efficiency by generating micron to nano-sized bubbles and extending their residence time in the water, making it suitable for river sections with greater water depth or higher dissolved oxygen requirements. In the aforementioned urban river with an average depth of approximately 2 meters and a width of approximately 30 meters, fountain aeration equipment can be deployed in landscaped sections, while propeller aeration equipment can be deployed in river sections with poor water flow.

[0072] In some embodiments, the filtration equipment includes a bypass biological filtration device arranged in a bypass channel of an urban river. For example, the bypass biological filtration device diverts a portion of the water from the main channel of the urban river to the bypass channel, where biological filter media is installed to filter and purify the diverted water before it flows back to the main channel. Because the filtration and purification take place within the bypass channel, the bypass biological filtration device causes less disturbance to the water flow in the main channel, thereby reducing process interference when the filtration device coexists with other multiple treatment devices such as aeration equipment and pump circulation devices arranged in the main channel.

[0073] In some embodiments, the hydrodynamic coupling rules also include the following two rules. The first rule is that, in response to the fountain aeration equipment being in operation, the pump pipe circulation device is prohibited from taking water within a preset distance range downwind of the fountain aeration equipment. For example, when the fountain aeration equipment is operating, foam is formed on the water surface. The foam drifts downwind under the influence of wind. If the pump pipe circulation device takes water within 30 meters downwind of the fountain aeration equipment, the drifting foam will be sucked into the pump inlet and cause cavitation. Therefore, in response to the fountain aeration equipment being in operation, the pump pipe circulation device does not take water within 30 meters downwind of the fountain aeration equipment.

[0074] The second provision states that, in response to the pump-pipe circulation device comprising multiple circulation pumps operating simultaneously, the distance between the water inlets of any two circulation pumps shall not be less than a preset pump spacing. For example, if the water inlets of two circulation pumps are too close together, their water intakes will mutually depressurize, creating a local low-pressure zone and causing unstable water intake. Therefore, the distance between the water inlets of any two circulation pumps shall not be less than a preset pump spacing of 20 meters.

[0075] In some embodiments, the chemical reaction coupling rules also include the following two rules. The first rule states that, in response to the flocculant dosing equipment being in operation, the pump-pipe circulation device is prohibited from operating within a preset flocculation isolation distance downstream of the flocculant dosing equipment. For example, after flocculant is added, suspended solids in the water gradually aggregate to form flocs. If the pump-pipe circulation device operates within 40 meters downstream of the flocculant dosing equipment, the shearing action of the pump impeller will break up the already formed flocs, causing flocculation and sedimentation to fail. Therefore, in response to the flocculant dosing equipment being in operation, the pump-pipe circulation device does not operate within the preset flocculation isolation distance of 40 meters downstream of the flocculant dosing equipment.

[0076] The second provision stipulates that, in response to the completion of sediment amendment application and the time remaining after application not exceeding a preset diffusion time, the water flow disturbance intensity in the area where the submerged plants are located must not exceed a preset disturbance threshold. For example, after the sediment amendment is applied, it needs to spread evenly and settle on the sediment surface. If the water flow disturbance intensity in the area where the submerged plants are located is too high at this time, the amendment will be carried away from the target area by the water flow and the distribution will be uneven. Therefore, within the preset diffusion time of 60 minutes after the sediment amendment is applied, the water flow disturbance intensity in the area where the submerged plants are located must not exceed the preset disturbance threshold of 0.3 meters per second.

[0077] In some embodiments, the bio-metabolic coupling rules also include the following two rules. The first rule states that, in response to the compound microbial preparation being dispensed by the dosing device, the dosing disinfection device is prohibited from operating if the time following dispensing does not exceed a preset inactivation protection time. For example, after the compound microbial preparation is dispensed, it needs a certain amount of time to multiply in the water and form a stable bacterial community. If the dosing disinfection device operates during this period, the disinfectant will kill the unstable bacterial community, rendering the dosing ineffective. Therefore, the dosing disinfection device does not operate within the preset inactivation protection time of 45 minutes after the compound microbial preparation is dispensed.

[0078] Article 2 stipulates that, in response to the identification of areas with high density of aquatic animal activity, the operation of strongly disturbing aeration equipment is prohibited within a preset safe distance range of such areas. For example, the strong water flow and bubbles generated by strongly disturbing aeration equipment can cause stress to aquatic animals such as fish. Therefore, after identifying areas with high density of aquatic animal activity, strongly disturbing aeration equipment will not operate within a preset safe distance range of 15 meters from these areas.

[0079] The above six rules, together with the three representative rules mentioned above, constitute multiple specific rules for each of the three mechanistic rules: hydrodynamics, chemical reaction, and biological metabolism. This improves the coverage and completeness of the physical-chemical coupling constraint library for process equipment, and provides sufficient rule support for the collaborative decision-making of multiple treatment devices under different equipment combinations.

[0080] In some embodiments, the aquatic animals arranged in the high-density aquatic animal activity area include at least one of freshwater mussels, river snails, freshwater shrimp, and silver carp. For example, freshwater mussels and river snails are benthic filter feeders that improve water quality by filtering suspended algae and organic debris from the water; freshwater shrimp are small omnivorous animals that feed on organic matter on the surface of the bottom sediment; and silver carp are filter feeders that feed on phytoplankton in the upper layers of the water. The activity areas of these aquatic animals, identified through underwater monitoring, serve as the basis for avoidance boundaries for aquatic animal protection in biological metabolism coupling rules, ensuring that the strongly disturbed aeration equipment operates outside a preset safe distance range from the high-density aquatic animal activity area.

[0081] In some embodiments, the physical-chemical coupling constraint library for process equipment is organized into a three-layer structure: a basic layer, an optimization layer, and an emergency layer.

[0082] The basic layer stores equipment-level avoidance rules that are independent of the local characteristics of urban rivers, such as the downstream isolation rules between aeration equipment and pump circulation devices, and the timing precedence rules between bacteria feeding equipment and filtration equipment. These rules reflect the common process coupling mechanism between equipment and do not depend on the specific river morphology and water quality characteristics. Therefore, they are stored in the basic layer and can be used in different urban river management projects.

[0083] The optimization layer stores the equipment-level avoidance rules obtained by calibrating the equipment-level avoidance rules in the base layer based on local operation data of urban inland rivers. For example, the preset isolation distance of 50 meters downstream of the aforementioned aeration equipment is a general value of the base layer. However, in the aforementioned urban inland river with an average water depth of about 2 meters and a width of about 30 meters, the isolation distance can be adjusted to a value that is suitable for the water flow conditions of the river after calibration with local operation data. The calibrated rules are stored in the optimization layer.

[0084] The emergency layer stores device-level avoidance rules that respond to abnormal water quality events. For example, when an abnormal water quality event such as blackening or algal bloom occurs in the water body, the rules in the emergency layer are triggered to adjust the operating strategies of multiple treatment devices.

[0085] Each equipment-level avoidance rule in the process equipment physicochemical coupling constraint library is further divided into hard avoidance rules and soft avoidance rules based on the reversibility of the coupling mechanism. Hard avoidance rules correspond to equipment-level avoidance rules with irreversible physicochemical coupling mechanisms, meaning that once violated, the resulting process losses cannot be recovered through subsequent operations. For example, after flocculant is added, the flocs are sheared and broken up by the pump impeller, and the broken flocs cannot re-aggregate. Therefore, the avoidance rule between the flocculant adding equipment and the pump pipe circulation device is a hard avoidance rule. Soft avoidance rules correspond to equipment-level avoidance rules with reversible physicochemical coupling mechanisms, meaning that the impact of violation can be recovered through subsequent operations or only causes efficiency losses. For example, the rule to reduce aeration intensity during the peak period of photosynthesis in submerged plants. Even if the aeration intensity is not reduced during a certain period, the effect of dissolved oxygen supersaturation will recover as dissolved oxygen dissipates naturally after the peak period. Therefore, this rule is a soft avoidance rule.

[0086] By organizing the process equipment physicochemical coupling constraint library through a three-layer structure of basic layer, optimization layer and emergency layer, the universal rules, local calibration rules and emergency rules are clearly managed in a hierarchical manner; by distinguishing hard avoidance rules and soft avoidance rules according to physicochemical reversibility, a graded basis is provided for priority adjustment when multiple rules conflict in S41 and soft rule downgrading when governance coverage is insufficient in S42.

[0087] In some embodiments, the equipment-level avoidance rules in the emergency response layer include triggering conditions in response to water pollution, algal blooms, or sudden pollution events, as well as restrictive actions for discharging compound mineral emergency remediation agents into urban rivers. For example, when persistently low dissolved oxygen levels are detected in the water accompanied by a black and odorous smell, it is determined to be a water pollution event, and the emergency response layer rules are triggered to discharge compound mineral emergency remediation agents into urban rivers to quickly improve the redox environment of the sediment and water. When a sharp increase in algal density is detected, it is determined to be an algal bloom event, and the emergency response layer rules are triggered to adjust the operating strategies of multiple treatment devices and coordinate with the discharging of compound mineral emergency remediation agents for algae removal.

[0088] In some embodiments, the equipment-level avoidance rules in the process equipment physicochemical coupling constraint library are stored in a lookup table manner. The avoidance conditions of each equipment-level avoidance rule are characterized by a binary parameter pair of distance and duration. For example, the avoidance rule between aeration equipment and pump pipe circulation device is characterized by a binary parameter pair of distance parameter 50 meters and duration parameter zero, and the avoidance rule between bacteria feeding equipment and filtration equipment is characterized by a binary parameter pair of distance parameter zero and duration parameter 30 minutes. By unifying and simplifying the avoidance conditions of each rule into a binary parameter pair of distance and duration, the process equipment physicochemical coupling constraint library can complete rule matching by looking up the table, reducing the computational complexity of the constraint library during on-site engineering deployment.

[0089] In some embodiments, each multi-treatment device performs a self-calibration step before commissioning. This step includes measuring the process disturbance parameters of the multi-treatment device, generating localized distance and duration parameters based on these parameters, and writing these parameters into the optimization layer of the process device's physicochemical coupling constraint library. For example, before commissioning an aeration device, the dissolved oxygen concentration decay curves at different downstream distances during operation are measured to determine the distance at which the dissolved oxygen concentration falls back to the background level. This distance is then used as a localized downstream isolation distance parameter for the aeration device and written into the optimization layer, replacing the universal 50-meter value in the base layer. Through this self-calibration, the distance and duration parameters in the process device's physicochemical coupling constraint library are locally calibrated, reducing the workload of engineers manually configuring parameters.

[0090] In some embodiments, the process equipment physicochemical coupling constraint library supports an online incremental learning sub-step. This sub-step includes periodically collecting collaborative operation data from multiple treatment devices, identifying coupling anomalies in device pairs not yet included in the constraint library, generating candidate avoidance rules, and writing them into the optimization layer of the constraint library after review. For example, if abnormal fluctuations in dissolved oxygen are detected during a period when aeration equipment and bacteria inoculation equipment are operating simultaneously, and the coupling relationship of this device pair is not yet included in the constraint library, the online incremental learning sub-step identifies this anomaly as a candidate avoidance rule between the aeration and bacteria inoculation equipment, and writes it into the optimization layer after manual review and confirmation. Through online incremental learning, the process equipment physicochemical coupling constraint library is continuously improved based on the operational experience of urban river treatment equipment.

[0091] Following the aforementioned constraint library construction, S2 involves monitoring the water quality of urban rivers and generating a spatial-temporal water quality field. For example, multiple water quality monitoring points are deployed along the aforementioned urban rivers. Each monitoring point collects real-time data on water quality indicators such as ammonia nitrogen, turbidity, and dissolved oxygen. The water quality indicators of each monitoring point at different times are organized according to spatial location and temporal order to generate a spatial-temporal water quality field reflecting the spatial and temporal distribution of urban river water quality. This field serves as the data foundation for identifying the centroid of pollution distribution and the dominant pollution type in subsequent S3.

[0092] Following the aforementioned water quality field generation, S3 identifies the pollution distribution centroid and dominant pollution type based on the spatial-temporal water quality field. For example, in the aforementioned spatial-temporal water quality field of the urban river, if the ammonia nitrogen concentration at each monitoring point along the river at a certain moment shows a distribution that is higher in the middle section and lower at both ends, then the spatially weighted centroid of the ammonia nitrogen concentration is determined as the pollution distribution centroid, which is located in the middle section of the urban river. By comparing the relative exceedance levels of various pollution indicators such as ammonia nitrogen and turbidity near the pollution distribution centroid, the pollution indicator with the highest exceedance level is determined as the dominant pollution type. The pollution distribution centroid reflects the spatial location of pollution accumulation, and the dominant pollution type reflects the main cause of pollution. Both serve as decision inputs for determining the avoidance planning and water intake / discharge topology pattern in subsequent S4.

[0093] In some embodiments, at least two types of submerged plants are arranged in the urban river, and the at least two types of submerged plants are selected from Vallisneria natans, Hydrilla verticillata, Elodea nuttallii, and Ceratophyllum demersum. For example, Vallisneria natans and Hydrilla verticillata are arranged in the aforementioned urban river. Identifying the pollution distribution centroid and dominant pollution type in S3 also includes auxiliary identification based on submerged plant habitat signals, which includes substeps S31 to S33.

[0094] S31 involves monitoring at least two morphological indicators of submerged plants, including at least two of the following: leaf moisture content, root growth status, and biomass per unit area. For example, images of Vallisneria natans and Hydrilla verticillata are periodically acquired using underwater imaging equipment, and two morphological indicators, leaf moisture content and biomass per unit area, are extracted from the images. Leaf moisture content reflects the degree of pollutants adhering to the surface of the submerged plant leaves, while biomass per unit area reflects the growth status of the submerged plant in the corresponding area.

[0095] S32 identifies the local distribution characteristics of pollution centroids in areas where at least two submerged plants are located, based on morphological indicators and preset pollution stress response mapping rules. It also identifies the dominant pollution type in the corresponding local mapping areas. For example, the preset pollution stress response mapping rules include the decrease in leaf moisture and biomass per unit area in *Vallisneria natans* under ammonia nitrogen stress, and the decrease in biomass per unit area in *Hydrilla verticillata* under turbidity stress due to reduced light transmittance. When *Vallisneria natans* in a certain area shows a decrease in leaf moisture and biomass per unit area, the local distribution characteristics of the pollution centroid in that area are identified, and the dominant pollution type in that area is identified as ammonia nitrogen. When *Hydrilla verticillata* in a certain area shows a decrease in biomass per unit area but no significant decrease in leaf moisture, the dominant pollution type in that area is identified as turbidity.

[0096] In S33, the local distribution characteristics, the dominant pollution type of the local mapped area, and the spatial-temporal water quality field obtained from water quality sensor monitoring are weighted and fused according to preset confidence weights to generate the final identification results of the pollution distribution centroid and the dominant pollution type. For example, the result identified based on the submerged plant habitat signal is assigned a confidence weight of 0.3, and the result identified based on the spatial-temporal water quality field monitored by the water quality sensor is assigned a confidence weight of 0.7. The two are then weighted and fused according to their confidence weights. When the two identification results are consistent, the weighted fusion improves the reliability of the identification result. When the two identification results differ, the water quality sensor result with the higher confidence weight is taken as the main result, and corrections are made by combining the submerged plant habitat signal.

[0097] By introducing habitat signals from submerged plants to aid in identification, in the gaps between water quality sensor monitoring points or when water quality sensors drift, submerged plants, as biological indicators of long-term water quality responses, provide supplementary information independent of water quality sensors for identifying the centroid of pollution distribution and the dominant pollution type, thereby improving the spatial coverage integrity and reliability of the identification results.

[0098] Building upon the aforementioned pollution identification results, S4 determines the avoidance plan for multiple treatment devices and the intake and drainage topology mode for the pump-pipe circulation device within these devices, based on the process equipment physicochemical coupling constraint library, the pollution distribution centroid, and the dominant pollution type. For example, given that the pollution distribution centroid is located in the middle section of an urban river and the dominant pollution type is ammonia nitrogen, it is determined that the operation of aeration equipment and bacteria inoculation equipment should be enhanced near the pollution distribution centroid. Simultaneously, the device-level avoidance rules whose trigger conditions are met are retrieved one by one from the process equipment physicochemical coupling constraint library to determine the avoidance actions that each multiple treatment device must follow, thus forming the avoidance plan for the multiple treatment devices. Furthermore, based on the location of the pollution distribution centroid and the dominant pollution type, the mode adopted by the pump-pipe circulation device in four intake and drainage topology modes—upstream and downstream longitudinal circulation, lateral short circulation, multi-point dispersed circulation, and static isolation circulation—is determined. The avoidance plan constrains process interference between multiple treatment devices, and the intake and drainage topology mode determines the hydraulic control path of the pump-pipe circulation device. Together, these two constitute the control basis for driving the operation of multiple treatment devices in S5.

[0099] In some embodiments, the pump-pipe circulation device includes at least two sets of water intake and drainage interfaces and a bidirectional switching valve group located between the at least two sets of water intake and drainage interfaces. The pump-pipe circulation device has a water intake position and a drainage position, and hydraulic circulation is formed between different positions in the urban river by switching the bidirectional switching valve group. The water intake and drainage topology modes include four modes: upstream and downstream longitudinal circulation mode, lateral short circulation mode, multi-point decentralized circulation mode, and static isolation circulation mode.

[0100] In the upstream-downstream vertical circulation model, the water intake point is located at the upstream end of the urban river and the drainage point is located at the downstream end, or vice versa. For example, in the aforementioned urban river with a length of approximately 5 kilometers, the pump-pipe circulation device draws water at the upstream end and discharges it at the downstream end, thereby forming a vertical hydraulic circulation along the entire length of the urban river, driving the water flow of the entire river channel to improve reoxygenation and mixing effects.

[0101] In the lateral short-circuit mode, the water intake and drainage locations are situated on the same bank of an urban river, and the distance between them is less than the preset short-circuit distance. For example, if both the water intake and drainage locations are on the same bank of an urban river and the distance between them is less than the preset short-circuit distance of 100 meters, a small-scale lateral hydraulic circulation is formed in a localized area, which is suitable for centralized treatment of localized pollution on a specific bank.

[0102] In the multi-point decentralized circulation mode, at least two sets of water intake and drainage interfaces operate synchronously at at least three segment locations in the urban river. For example, water intake and drainage interfaces are arranged and operate synchronously at at least three segment locations along the urban river, so that multiple segments simultaneously form their own local hydraulic circulation, which is suitable for situations where pollution is scattered in multiple locations in the urban river.

[0103] In the static isolation circulation mode, the pump-pipe circulation device operates only within a pre-defined isolation section of the urban river where the pollution distribution centroid is located. The two ends of this pre-defined isolation section are isolated from the rest of the urban river via a bidirectional switching valve assembly. For example, when the pollution distribution centroid is identified as a localized section containing a sudden pollution source, the two ends of this section are isolated from the rest of the urban river via the bidirectional switching valve assembly. The pump-pipe circulation device operates only within this pre-defined isolation section, preventing the sudden pollution from spreading with the water flow to the rest of the urban river.

[0104] By setting the above four intake and drainage topology modes and bidirectional switching valve groups located between at least two sets of intake and drainage interfaces, the pump pipe circulation device can switch between different hydraulic control paths according to the centroid of pollution distribution and the dominant pollution type, so that the hydraulic control matches the spatial distribution of pollution.

[0105] In some embodiments, the selection of the water intake and drainage topology mode is performed according to the following mapping rules.

[0106] In response to the dominant pollution type being ammonia nitrogen and the centroid of pollution distribution being located in the middle section of the urban river, a longitudinal circulation model between upstream and downstream is selected. For example, ammonia nitrogen pollution usually originates from continuous discharge from upstream and accumulates along the river. The centroid of pollution distribution being located in the middle section indicates that the pollution is distributed in a longitudinal band. Adopting a longitudinal circulation model between upstream and downstream to drive the flow of water throughout the entire river is beneficial for dispersing the ammonia nitrogen accumulated in the middle section through longitudinal circulation and for nitrification treatment in conjunction with aeration equipment.

[0107] In response to the dominant pollution type being turbidity and the centroid of pollution distribution being biased towards one bank of an urban river, a lateral short-circuit model is selected. For example, turbidity pollution usually originates from localized scouring or discharge on one bank, and the centroid of pollution distribution being biased towards one bank indicates that the pollution is distributed locally in a lateral manner. Adopting a lateral short-circuit model to form a small-scale circulation on this bank is beneficial for the concentrated treatment of localized turbidity without disturbing other areas.

[0108] In response to the identification of multiple pollution distribution centroids scattered throughout urban rivers in a spatial-temporal water quality field, a multi-point decentralized circulation mode is selected. For example, when multiple pollution distribution centroids appear simultaneously in urban rivers, the multi-point decentralized circulation mode is adopted to enable multiple segments to form local circulation simultaneously, thereby achieving parallel treatment of pollution from multiple locations.

[0109] In response to the identification of a sudden pollution event in the spatial-temporal water quality field, where the centroid of the pollution distribution is surrounded by a preset isolation segment, a static isolation loop mode is selected. For example, when a sudden pollution event occurs in a certain segment, the static isolation loop mode is used to isolate that segment to prevent the pollution from spreading.

[0110] In response to situations where the dominant pollution type is neither ammonia nitrogen nor turbidity, or where no multiple pollution distribution centroids are identified in the spatial-temporal water quality field and no sudden pollution event is identified, the upstream-downstream longitudinal circulation mode is selected as the default mode. For example, when the dominant pollution type is another pollution indicator not explicitly listed in the aforementioned mapping rules, or when the pollution distribution characteristics do not meet any of the conditions of lateral localization, multiple dispersions, or sudden isolation, the upstream-downstream longitudinal circulation mode is adopted as the default mode to ensure that the pump pipe circulation device has a definite intake and drainage topology mode available under various operating conditions.

[0111] By establishing a mapping rule between the selection of the intake and drainage topology mode and the location of the dominant pollution type and the centroid of pollution distribution, and setting a default mode as a fallback, the pump-pipe circulation device can determine a matching hydraulic control path under various pollution distribution conditions.

[0112] In some embodiments, determining the avoidance plan and water intake / drainage topology pattern in S4 further includes sub-steps S41 and S42.

[0113] In S41, in response to multiple equipment-level avoidance rules in the process equipment physicochemical coupling constraint library being triggered simultaneously and conflicting with the water intake / discharge topology mode, the conflict between the multiple equipment-level avoidance rules and the water intake / discharge topology mode is mediated according to a preset priority table. In the preset priority table, the priority of hard avoidance rules is higher than that of soft avoidance rules, which in turn is higher than that of the water intake / discharge topology mode, which is higher than that of soft avoidance rules. For example, when the lateral short circulation mode selected based on the centroid of pollution distribution requires the pump pipe circulation device to operate locally on a certain bank, and this location simultaneously falls within the prohibited operating range defined by the hard avoidance rule 40 meters downstream of the flocculant dosing equipment, a conflict occurs. Since the avoidance rule between the flocculant dosing equipment and the pump pipe circulation device is a hard avoidance rule and its priority is higher than that of the water intake / discharge topology mode, the hard avoidance rule is satisfied first according to the preset priority table. The pump pipe circulation device avoids the prohibited operating range, and the lateral short circulation mode adjusts the water intake / discharge location without violating the hard avoidance rule. For example, when the water intake and drainage topology pattern conflicts with the soft avoidance rule that reduces aeration intensity during the peak photosynthesis period of submerged plants, the water intake and drainage topology pattern takes precedence over the soft avoidance rule.

[0114] In S42, after S41 is executed, the treatment coverage rate of the multiple treatment devices during operation according to the avoidance plan is calculated. If the treatment coverage rate is lower than a preset coverage threshold, soft avoidance rules that are still triggered after S41 adjustment are allowed to be downgraded, causing the portion of the multiple treatment devices restricted by the soft avoidance rules to enter a limited operating state. For example, the treatment coverage rate is the ratio of the actual treatment capacity of the multiple treatment devices to the required treatment capacity of the urban river. When a large number of soft avoidance rules are triggered after S41 adjustment, resulting in multiple multiple treatment devices being restricted from operation and the treatment coverage rate falling below the preset coverage threshold of 70%, the soft avoidance rules are allowed to be downgraded. For example, aeration equipment during the peak photosynthetic period of submerged plants is allowed to operate at a limited intensity between 60% and full intensity, rather than being completely reduced to 60% of full intensity. This allows some treatment capacity to be restored within the reversible process loss range, causing the treatment coverage rate to rise back above the preset coverage threshold.

[0115] By resolving conflicts through the three-element priority system in S41, which prioritizes hard avoidance rules over water intake and drainage topology modes and vice versa, and by allowing soft avoidance rules to be downgraded in S42 when the treatment coverage is insufficient, the system ensures that the physicochemically irreversible hard avoidance rules are not violated, while taking into account both the hydraulic control objectives and treatment coverage requirements of the water intake and drainage topology modes.

[0116] In some embodiments, the avoidance planning in S4 also includes a multi-device substitution mechanism. In response to a device-level avoidance rule triggering a multi-treatment device to enter an avoidance state, another multi-treatment device with functional equivalence to the triggering device is selected from a preset multi-device substitution pool and activated, ensuring that the treatment coverage does not decrease due to the avoidance rule triggering. For example, the preset multi-device substitution pool may register micro-nano aeration devices and push-flow aeration devices as a group of devices with equivalent reoxygenation functions. When a micro-nano aeration device enters an avoidance state because it falls within the prohibited operating range of a hard avoidance rule, a push-flow aeration device located outside the prohibited operating range is selected from the multi-device substitution pool and activated. The push-flow aeration device then assumes the reoxygenation task originally performed by the micro-nano aeration device, thereby maintaining the reoxygenation capacity of the urban river while complying with the avoidance rule. Through the multi-device substitution mechanism, the triggering of the avoidance rule no longer comes at the cost of sacrificing the treatment coverage.

[0117] Building upon the decision-making results of the aforementioned avoidance planning and water intake / discharge topology patterns, S5 drives the operation of multiple treatment devices according to the avoidance planning and water intake / discharge topology patterns, and adjusts the avoidance planning and water intake / discharge topology patterns based on the evolution feedback of the spatial-temporal water quality field. For example, operating instructions are issued to each of the multiple treatment devices according to the avoidance plan, and the bidirectional switching valve group of the pump pipe circulation device is controlled according to the selected water intake / discharge topology pattern, enabling the multiple treatment devices to operate according to collaborative decision-making. During operation, the evolution of the spatial-temporal water quality field is continuously monitored. When the location of the pollution distribution centroid shifts or the dominant pollution type changes, the system returns to S3 and S4 to re-identify and redetermine the avoidance planning and water intake / discharge topology patterns, forming a closed-loop control system of monitoring, identification, decision-making, and execution.

[0118] In some embodiments, during the operation of the pump-pipe circulation device in S5 according to the water intake / discharge topology mode, a minimum residence time for the water intake / discharge topology mode is set. Once any water intake / discharge topology mode is activated, it must maintain at least the minimum residence time before switching to the next water intake / discharge topology mode. For example, setting the minimum residence time for the water intake / discharge topology mode to 2 hours means that even if the centroid of the pollution distribution fluctuates briefly after a certain water intake / discharge topology mode is activated, the current mode must be maintained for at least 2 hours before switching to the next water intake / discharge topology mode is allowed. Since the establishment of hydraulic circulation and water quality response require a certain amount of time, setting a minimum residence time can avoid frequent switching of the water intake / discharge topology mode due to short-term fluctuations in the centroid of the pollution distribution, thereby reducing the energy consumption increase and the decrease in control effect caused by frequent start-up and shutdown of the pump-pipe circulation device and repeated establishment of hydraulic circulation.

[0119] In some embodiments, the switching between intake and drainage topology modes includes a transitional control sub-step. This sub-step involves first gradually closing the intake and drainage interfaces corresponding to the original intake and drainage topology mode according to a preset decreasing rule during the switching process. After a preset transition buffer period, the intake and drainage interfaces corresponding to the new intake and drainage topology mode are then gradually opened according to a preset increasing rule. For example, when switching from a longitudinal circulation mode to a transverse short circulation mode, the flow rate of the intake and drainage interfaces corresponding to the original longitudinal circulation mode is gradually reduced until they are closed according to a preset decreasing rule over a period of time. After a preset transition buffer period of 10 minutes to allow the hydraulic circulation in the river channel to stabilize, the intake and drainage interfaces corresponding to the transverse short circulation mode are then gradually opened and the flow rate is increased according to a preset increasing rule. Through transitional control, the switching of intake and drainage topology modes will not cause drastic changes in the hydraulics of the river channel due to the sudden opening and closing of the intake and drainage interfaces, thus avoiding hydraulic impact on existing flocs, submerged plants, etc.

[0120] This application also provides a computer device, as described in the embodiments. Figure 3The computer equipment includes a memory and a processor. The memory stores a computer program, which, when executed by the processor, implements the aforementioned method for coordinated control of urban river management equipment. For example, the computer equipment can be an industrial control computer deployed at the site of urban river management. The industrial control computer connects to various multi-treatment devices, water quality monitoring points, and bidirectional switching valve groups of pump circulation devices via communication interfaces, loading and executing the computer program to achieve coordinated control of multiple treatment devices.

When executed by a processor, the computer program implements the aforementioned method for coordinated control of urban river management equipment. The computer-readable storage medium stores at least one instruction, at least one program segment, a code set, or an instruction set. The at least one instruction, the at least one program segment, the code set, or the instruction set is loaded and executed by a processor to implement the aforementioned method for coordinated control of urban river management equipment. For example, the computer-readable storage medium can be a read-only memory, a random access memory, a magnetic disk, or an optical disk, etc.
