Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically, to a method, system, electronic device, and storage medium for preventing siltation in wastewater transfer culverts. Background Technology

[0002] In my country, most cities, especially older urban areas, use combined sewer systems, leading to serious combined sewer overflow (CSO) pollution problems. During rainy days, combined sewer overflows frequently overflow, causing road flooding and disrupting traffic. Furthermore, CSO pollutes large volumes of poor-quality water (especially from initial rainfall), and is discharged directly into urban waterways without any treatment, causing significant impact on water quality and, in severe cases, rendering them unable to self-purify. Therefore, effectively controlling CSO pollution has become an urgent priority in solving urban water environment problems.

[0003] Currently, traditional CSO pollution control measures mainly include the renovation of combined sewer systems (CSO) transmission pipelines (such as constructing new transmission culverts), increasing the treatment capacity of wastewater treatment plants, and constructing storage facilities. Among these, wastewater transmission culverts are crucial channels for CSO wastewater transmission, and their transport capacity directly affects the outlet of upstream CSO wastewater during rainfall and the effective functioning of downstream treatment facilities. However, in traditional wastewater transmission culverts, the wastewater flow velocity varies depending on the rainfall intensity. When rainfall intensity is low or in the later stages of rainfall, the wastewater flow velocity decreases, leading to silt deposition. After the rainfall ends, the deposited silt hardens and compacts within the culvert, creating a vicious cycle that severely reduces the culvert's water-carrying capacity. Therefore, how to reduce the reduced water-carrying capacity of wastewater transmission culverts due to siltation, thereby preventing localized flooding and wastewater overflows, is an urgent problem to be solved. Summary of the Invention

This improves the culvert's water conveyance capacity and reduces the occurrence of localized flooding and sewage overflows. Attached Figure Description

[0035] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0036] Figure 1 A schematic diagram of a sewage transfer culvert anti-siltation system provided by the present invention is shown below. Figure 1 As shown, the system includes: a prediction and early warning module, a model calculation module, an intelligent analysis module, and an intelligent decision-making module, wherein the intelligent analysis module is connected to the prediction and early warning module, the model calculation module, and the intelligent decision-making module, respectively.

[0037] The system includes a preset early warning module for acquiring real-time short-term weather forecast data and sending it to the intelligent analysis module; a model calculation module for calculating combined sewer flow process data based on monitoring station data within the upstream river catchment area using a preset hydraulic model and feeding the process data back to the intelligent analysis module; an intelligent analysis module for analyzing the forecast weather data and the process data and sending the analysis results to the intelligent decision-making module; and an intelligent decision-making module for controlling the opening and closing of each gate of the sewage transmission culvert based on the analysis results and corresponding control strategies.

[0038] It should be noted that the forecast meteorological data in the above short-term weather forecast can be based on meteorological data for a future period of time provided by a third-party system. In order to improve the accuracy of the data and reduce the computing power requirements of the system, it can be set to meteorological data for the next hour.

[0039] The aforementioned forecasting and early warning module mainly serves the intelligent analysis module and intelligent decision-making module based on meteorological data for the next hour, enabling them to formulate response strategies in advance based on the current and next hour's meteorological conditions.

[0040] The aforementioned model calculation module primarily utilizes a pre-set hydraulic model system to generate model parameters and establish the model based on historical monitoring data of rainfall and sewage flow from the upstream river culvert. The generated model calculates combined sewer sewage flow process data using data from monitoring stations located within the upstream river catchment area and feeds the combined sewer sewage inflow process line back to the intelligent analysis system. The analysis system then selects appropriate response strategies based on the flow processes formed at different rainfall depths and the principle of water balance.

[0041] The aforementioned preset hydraulic model can be constructed in advance based on historical data.

[0042] To further explain the functional modules of the system of the present invention in detail, see [link to documentation]. Figure 2 , Figure 2 This invention provides a detailed architecture diagram of a sewage transfer culvert anti-siltation system. Figure 2 The system of this invention, also known as a smart water management decision-making platform, includes: a data storage module, a forecasting and early warning system, a smart analysis system, a hydraulic model system, and a feedback correction system. The preset early warning system performs forecasting and early warning analysis by acquiring meteorological data for the next hour. The above modules interact with various monitoring stations in the area via wireless networks (including but not limited to: 2G / 3G / 4G / 5G), including but not limited to: rainfall monitoring stations, water quality monitoring stations, water level monitoring stations, flow monitoring stations, wastewater monitoring stations, and meteorological monitoring stations. By constructing the above smart water management system, based on the model's prediction of the current and next hour's changes in combined sewer overflow (CSO) water volume, corresponding response strategies are formulated to fully utilize the treatment capacity of each treatment facility, minimize pollution from initial combined sewer overflows during rainfall, reduce the frequency and volume of CSO overflows, protect the river water environment in the area, and create significant direct and potential economic value.

[0043] It should be understood that the present invention also provides a combined sewer pollution reduction rapid response control system, see [link to relevant documentation]. Figure 3 and Figure 4 ,exist Figure 3 and Figure 4 The CSO (Concentrated Soil Oxygenation) transport culvert is divided into multiple channels, each equipped with an independently opening gate. A hydraulic model, based on current rainfall monitoring and forecasts for the next hour, develops a gate opening and closing control strategy to ensure that the wastewater flow velocity within each channel is not lower than the sedimentation velocity. Simultaneously, as rainfall nears its end, the CSO wastewater turbidity is relatively low; at this time, the gate control strategy is adjusted to flush each channel, reducing the risk of sediment accumulation within the culvert.

[0044] Figure 3 and Figure 4The following are the designated numbers for each type of river: ① Upstream culvert, ② Open channel, ③ Downstream channel, ④ Sewage transfer culvert (4-1, 4-2, 4-3), ⑤ Urban residential sewage network, ⑥ Sewage treatment plant, ⑦ CSO storage tank, ⑧ CSO enhanced treatment facility, ⑨ Sewage transfer culvert gate 1 (9-1, 9-2, 9-3), 10.

[0045] The silt prevention design for box culverts is based on the following formula:

[0046] The flow velocity of each compartment in a combined sewer system transport culvert is calculated using the following formula:

[0047]

[0048] Where v is the sewage flow velocity in the box culvert (m / s), R is the hydraulic radius (m), I is the hydraulic gradient, and n is the roughness coefficient.

[0049] Q = Av;

[0050] Where Q is the sewage flow rate inside the box culvert (m³) 3 / s), v is the sewage flow velocity inside the box culvert (m / s), and A is the sewage flow area (m²). 2 ).

[0051] To prevent siltation within the combined sewer system's transport culvert, the flow velocity needs to be controlled to at least 0.75 m / s, corresponding to the calculated controlled flow rate of the sewage within the culvert. During subsequent operation, the intelligent control system uses flow rate and velocity monitoring instruments placed within the culvert to ensure the controlled flow rate and velocity.

[0052] In the later stages of rainfall, the combined sewage quality gradually improves and the turbidity drops to its lowest level. At this time, the intelligent control system will control the opening and closing of the gates at the entrance of each compartment of the box culvert according to the upstream rainfall and water volume, and flush each compartment to ensure that there is no siltation inside the box culvert.

[0053] To further enhance the system's ability to reduce the risk of sediment accumulation within the culvert, a wastewater treatment plant is installed at the beginning of the open channel, and a CSO (Concentrated Soluble Oxide) storage tank and enhanced CSO treatment facilities are installed at the end, along with a transfer culvert connecting the underground culvert and the end of the open channel. Each facility has a bottom-opening gate at its inlet to enable coordinated operation of all treatment facilities, thereby minimizing CSO overflow into the open channel and preventing water environment deterioration. This is crucial for supporting the intelligent water management decision-making system.

[0054] Secondly, various monitoring stations and equipment are set up within the system, facilities, and river channels, such as rainfall monitoring stations, sewage monitoring stations, and water quality and quantity testing equipment for flow rate, velocity, water level, and turbidity. Specifically, water quality and water level monitoring instruments are installed in the culverts of the upstream river channel; rainfall monitoring stations, sewage flow rate, and water quality monitoring stations are installed in the confluence area of ​​the upstream river channel; a flow monitoring station is installed at the gate at the inlet of the sewage treatment plant; flow rate and velocity monitoring instruments are installed in the sewage transmission culvert; water level monitoring instruments are installed in the CSO regulating tank; and flow rate monitoring instruments are installed in the CSO enhanced treatment facility.

[0055] Understandably, based on the deficiencies in the background technology, this invention proposes a sewage transfer culvert anti-siltation system. The system includes: a prediction and early warning module, a model calculation module, a smart analysis module, and a smart decision-making module. This invention calculates the process data of combined sewer overflow from monitoring data using a hydraulic model, and analyzes the process data and predicted meteorological data to obtain the analysis results and corresponding control strategies. Based on these control strategies, the opening and closing of each gate in the sewage transfer culvert are controlled, thereby ensuring that the sewage flow velocity in each compartment of the culvert is not lower than the siltation velocity. This minimizes combined sewer overflow pollution, reduces the frequency and volume of sewage transfer culvert overflows, and also reduces the drying and compaction of sediment caused by the alternating wet and dry conditions inside the culvert due to intermittent use. This improves the water conveyance capacity of the sewage culvert and reduces the occurrence of localized flooding and sewage overflows.

[0056] As an example, the sewage transmission culvert silt prevention system further includes: a data storage module;

[0057] The data storage module is used to store real-time monitoring data from multiple monitoring stations and the process data.

[0058] It should be noted that the data storage module mainly includes front-end monitoring data and system operation data. Front-end monitoring data primarily includes data such as the flow rate, water quality, and water level of combined sewer overflows entering the upstream river culvert. It also stores combined sewer flow process data calculated by the hydraulic model based on monitoring stations located within the upstream river catchment area and meteorological monitoring data. System operation data mainly consists of data from the intelligent analysis and decision-making system.

[0059] In this embodiment, during non-rainfall periods, the area's pipe network only discharges sewage. Water quality, flow rate, velocity, and water level are monitored once per hour. During rainfall, to ensure accurate control of data on the inflow of combined sewer system sewage, monitoring is conducted once per minute. Other monitoring data, such as rainfall data, are also collected once per minute. The monitored data are stored in formats such as Excel and Word. The accuracy of water quality indicators, flow rate, and velocity monitoring is controlled within 3%, and the water level monitoring error is controlled within 2 cm.

[0060] As an example, the sewage transmission culvert silt prevention system further includes: a model feedback module;

[0061] The model feedback module is used to perform difference analysis based on the monitoring data and the process data, and to correct the model parameters of the preset hydraulic model based on the difference analysis results.

[0062] Understandably, the aforementioned model feedback module can continuously correct model parameters by comparing and analyzing the differences between the real-time monitoring data of each station in the data storage module and the data generated by the model prediction, so that the model simulation data is closer to reality and the deviation is reduced.

[0063] In this embodiment, the system simulates and calculates the rainfall depth for the current and next hour based on a hydraulic model, while simultaneously measuring the flow data generated by each rainfall event. A feedback correction system is added to the system to continuously correct the model parameters based on the comparison between the model and the measured data, ensuring the accuracy of the model prediction and increasing the reliability of the intelligent management and control system.

[0064] As an example, the data storage module is also used to issue an alarm based on abnormal conditions in the monitoring data.

[0065] In this embodiment, the data storage module can identify the monitoring data of the front-end monitoring equipment and promptly alarm when abnormal or missing monitoring data occurs, so that maintenance personnel can monitor and repair it.

[0066] As an example, the forecasting and early warning module is also used to adjust the data acquisition frequency when the forecasted meteorological data is detected to meet preset conditions.

[0067] In this embodiment, the aforementioned forecasting and early warning module is used to collect real-time updated short-term weather forecast data to serve the intelligent analysis system and decision-making system, enabling proactive response strategies based on current and future weather conditions within the next hour. During sunny weather, short-term weather data is collected once every 30 minutes. When rainfall is predicted to occur within the next 30 minutes, the monitoring frequency is increased to once every 5 minutes to ensure the timeliness of the acquired weather data.

[0068] As an example, the model calculation module is also used to initialize the preset hydraulic model based on multi-factor environmental data.

[0069] It should be noted that the above initialization steps can be the steps of hydraulic model construction. The construction of the hydraulic model is based on historical rainfall monitoring data of the combined sewer system area, deriving the unit flow curve of the time period in the area, generating the flow process curve formed by historical rainfall events, and at the same time, according to the population, living habits, and seasonal changes of the area, combined with the local measured sewage discharge process, comparing it with the measured runoff process formed by the corresponding historical rainfall events, correcting and adjusting the model parameters to make it fit the historical rainfall runoff data and ensure the accuracy of the model.

[0070] In this embodiment, the hydraulic model, based on the river's historical, current, and one-hour rainfall data, focuses on the present while considering the next hour. It generates corresponding control strategies based on the changes in rainfall over time, addressing issues such as insufficient predictability of wastewater discharge in combined sewer systems, leading to delayed responses from plants, stations, and networks, and resulting in initial rainwater overflows. This provides a smart decision-making and control strategy for the coordinated operation of plants, stations, and networks in urban combined sewer systems, improving urban water management and maximizing the protection of the natural aquatic environment.

[0071] As an example, the sewage transmission culvert anti-siltation system further includes: a culvert flushing module;

[0072] The culvert flushing module is used to flush the sewage transmission culvert based on the analysis results of the intelligent analysis module.

[0073] In practice, during the later stages of rainfall, when the intelligent analysis module calculates that the water storage capacity within the culvert will gradually decrease, the gates in one section of the sewage transmission culvert remain open while the gates in other sections are closed. The relatively good water quality from the later stages of rainfall is used to flush each section of the culvert. The flushing velocity and flow rate are determined based on the water quality during the later stages of rainfall: when the turbidity of the incoming water is ≥500 NTU, the flow velocity is ≥1.5 m / s; when the turbidity is ≥200 NTU, the flow velocity is ≥0.75 m / s, ensuring that the culvert does not accumulate sediment. The flushing time for each section is controlled at 5 minutes. Afterwards, another section gate is opened, and the gate of the current section is closed for flushing, and so on.

[0074] In this embodiment, the sewage transmission culvert is flushed according to the analysis results of the intelligent analysis module, so that the silt in the sewage transmission culvert is washed again by the water flow, ensuring that the culvert does not accumulate, thereby greatly improving the sewage transmission capacity of the sewage transmission culvert, reducing the overflow of the culvert caused by siltation and reducing the overflow flow.

[0075] As an example, the intelligent analysis module mainly assesses the inflow of water into the river culvert based on front-end monitoring and prediction data, combined with a hydraulic model, to support the intelligent water management decision-making platform. Its working principle is based on the water balance principle.

[0076] (Q1+Q2-Q3-Q4-Q5)×t≤V;

[0077] Where Q1 is the real-time flow rate (m³) of rainfall calculated by the hydraulic model. 3 / s), Q2 is the wastewater discharge flow rate (m³ / s), 3 / s), Q3 is the influent flow rate of the wastewater treatment plant (m³ / s). 3 / s), Q4 is the sewage transmission culvert flow rate (m³ / s), 3 / s), Q5 is the open channel discharge flow rate (m³ / s), 3 / s), V is the upstream river channel culvert storage capacity (m³ / s), 3 ).

[0078] The intelligent analysis module calculates the activation status of treatment facilities according to the priority order of sewage treatment plants, CSO enhanced treatment facilities, CSO storage tanks, and open channel discharge, and the corresponding treatment facilities for various rainfall strategies.

[0079] As an example, the intelligent decision-making platform in this system is the key to the operation and control of the entire system. Its function is to control the opening and closing of the corresponding gates by analyzing the results of the intelligent analysis system, and further control the discharge of water from the river culvert during rainfall. This fully mobilizes the response capabilities of the plant, station and network to combined sewer system, ensures that the initial rainwater is effectively controlled, and further achieves the goals of water safety and water environment control.

[0080] To achieve the above functional objectives, a wastewater treatment plant will be installed at the beginning of the open channel, and a CSO storage tank and CSO enhanced treatment facilities will be installed at the end, along with a transmission culvert connecting the underground culvert and the end of the open channel. Each facility's inlet will be equipped with a bottom-opening gate. The time from fully opening to fully closing and from fully closing to fully opening of the gates should be controlled within 30 seconds. Simultaneously, the opening degree of each gate should be precisely controlled based on flow balance, with an opening degree error not exceeding 3 cm.

[0081] See Table 1, which is the instruction matrix diagram of the smart water management decision-making platform provided by the present invention. Table 1 shows the relationship between weather and strategy. The rainfall amounts h1, h2 and h3 can be set according to the rainfall data and control standards of each city area.

[0082] Table 1. Command Matrix Diagram of the Smart Water Management Decision-Making Platform

[0083]

[0084]

[0085] The intelligent decision-making and control strategies are as follows:

[0086] Strategy 1: If the current and next hour's weather conditions are both sunny, the combined sewer system will only discharge wastewater, with no rainwater entering. The smart water management decision-making platform will generate a command to keep gate 17 of the wastewater treatment plant open and all other gates 9-16 closed. All wastewater in the area will be treated at the wastewater treatment plant before being discharged.

[0087] Strategy 2: If the weather is currently sunny and a light rain is forecast within the next hour with a rainfall depth not exceeding h1, the forecast and early warning system will send the forecast rainfall depth to the hydraulic model to calculate the flow rate. The intelligent analysis system will calculate based on the water balance principle that if the storage capacity in the culvert is insufficient during the rainfall period and there is a risk of water stagnation in the area, the CSO enhanced treatment facility needs to be activated to meet water safety requirements. At this time, gates 9-1, 10-1, 11-1, 12-1, and 15 will be opened to activate the CSO enhanced treatment facility in advance, ensuring that the facility can operate at its maximum load during the rainfall.

[0088] Strategy 3: Currently sunny, with a weather forecast predicting moderate rain within the next hour and a rainfall depth not exceeding h2, the intelligent analysis system calculates the need to activate the CSO enhanced treatment facility and CSO storage tank to meet water security requirements. Therefore, prioritizing the opening of gates 9-1, 10-1, 11-1, 12-1, and 15 before rainfall, the CSO enhanced treatment facility will be activated in advance to ensure it operates at maximum capacity during rainfall. When rainfall occurs, gates 9, 10, 11, 12, and 14 will be opened, allowing combined sewage to be collected and treated by the sewage treatment plant, CSO enhanced treatment facility, and CSO storage tank. Once the storage tank is full, gate 14 will be closed and gate 13 will be opened to divert the sewage to the downstream river channel.

[0089] Strategy 4: Currently sunny, with a weather forecast predicting heavy rain within the next hour, and a rainfall depth not exceeding h3, the intelligent analysis system calculates that simultaneously operating the CSO enhanced treatment facility and CSO storage tank will not meet water safety requirements. Therefore, before rainfall, gates 9-1, 10-1, 11-1, 12-1, and 15 should be opened first to activate the CSO enhanced treatment facility ahead of schedule, ensuring it operates at maximum capacity during rainfall. Once rainfall occurs but before the peak flow is reached, gates 9, 10, 11, 12, and 14 should be opened first, allowing combined sewer wastewater to collect initial rainwater to the maximum extent possible through the wastewater treatment plant, CSO enhanced treatment facility, and CSO storage tank. When the peak flow is reached, gate 13 should be opened to transport water from the upstream culvert downstream through a box culvert, preventing overflow and river pollution.

[0090] Strategy 5: Currently sunny, but a heavy rainstorm is forecast within the next hour, with a depth exceeding h3. The intelligent analysis system calculates that simultaneously operating the CSO enhanced treatment facility, CSO storage tank, and culvert cannot meet water safety requirements. Therefore, before the rainfall, gates 9-1, 10-1, 11-1, 12-1, and 15 should be opened first to activate the CSO enhanced treatment facility ahead of schedule, ensuring it operates at maximum load during the rainfall. Once rainfall occurs but before the peak flow is reached, gates 9, 10, 11, 12, and 14 should be opened first, allowing combined sewer wastewater to collect initial rainwater to the maximum extent possible through the wastewater treatment plant, CSO enhanced treatment facility, and CSO storage tank. When the inflow exceeds the treatment facility's collection capacity, gate 13 should be opened to transport water from the upstream culvert to the downstream via the culvert. When the flow exceeds the culvert's transport capacity, to ensure water safety, the opening of gate 16 should be dynamically controlled to minimize overflow into the river channel.

[0091] Strategy 6: The current light rain rainfall is h1. The weather forecast predicts that the rain will stop within the next hour. At this time, the dispatching rules are as follows: keep gates 17, 9-1, 10-1, 11-1, 12-1, and 15 open. In the later stages of the rainfall, close the gates leading to the CSO intensified treatment facility.

[0092] Strategy 7: The current light rain rainfall is h1, and the weather forecast indicates that light rain will continue for the next hour. At this time, the dispatching rules are as follows: keep gates 17, 9-1, 10-1, 11-1, 12-1, and 15 open. In the later stages of the rainfall, close the gates leading to the CSO intensified treatment facility.

[0093] Strategy 8: Current rainfall is light (h1), and the weather forecast predicts moderate rain within the next hour, with a depth not exceeding h2. The dispatching rules are as follows: Keep gates 17, 9-1, 10-1, 11-1, 12-1, and 15 open. When the rainfall increases and the inflow exceeds the treatment capacity of the wastewater treatment plant and the CSO enhanced treatment facility, open gates 9, 10, 11, 12, and 14. Combined sewage will then be collected and treated jointly by the wastewater treatment plant, the CSO enhanced treatment facility, and the CSO storage tank. Once the storage tank is full, open gate 13.

[0094] Strategy 9: Current light rain rainfall is h1. Weather forecast predicts heavy rain within the next hour, with a depth not exceeding h3. The dispatching rules are as follows: Open gates 9, 10, 11, 12, 14, and 15 of the box culvert to increase collection and processing capacity and reduce water storage in the culvert to prepare for subsequent heavy rain. During heavy rain, when the inflow exceeds the collection and processing capacity and the culvert water level reaches 80% of its depth, open gate 13 to release water and ensure water safety.

[0095] Strategy 10: Current light rain rainfall h1, weather forecast predicts heavy rain within the next hour, with a depth exceeding h3. The dispatching rules are as follows: Open gates 9, 10, 11, 12, 14, and 15 of the box culvert to increase collection and treatment capacity and reduce water storage in the culvert to prepare for the subsequent heavy rain. When the heavy rain occurs, if the inflow exceeds the collection and treatment capacity and the culvert water level reaches 60% depth, open gate 13 to release water. If the culvert water level continues to rise and reaches 90% depth, dynamically control the opening of gate 16 to control the overflow into the river channel.

[0096] Strategy 11: The current rainfall is moderate (h2), and the weather forecast indicates that the rainfall will stop within the next hour. At this time, the dispatching rules are as follows: keep gates 9, 10, 11, 12, 14, 15, and 17 open. After the storage tank is full or the rainfall ends, gradually close the gates leading to the storage tank and the CSO enhanced treatment facility in conjunction with the culvert flushing procedure.

[0097] Strategy 12: The current rainfall is moderate (h2). The weather forecast predicts light rain within the next hour, with a rainfall depth not exceeding h1. The dispatching rules are as follows: Keep gates 9, 10, 11, 12, 14, 15, and 17 open. If the storage tank is full and the moderate rain has not stopped, open gate 13. If the moderate rain has stopped before the storage tank is full, close gate 14. In conjunction with the culvert flushing procedure, gradually close two of the culvert's separating gates, leaving one gate open to guide the sewage to the CSO enhanced treatment facility.

[0098] Strategy 13: The current rainfall is moderate (h2). The weather forecast predicts that moderate rain will continue for the next hour, with a rainfall depth not exceeding h2. At this time, the dispatching rules are as follows: keep gates 9, 10, 11, 12, 14, 15, and 17 open. At this time, the regulating reservoir and the CSO enhanced treatment facility will collect and treat the water together. After the regulating reservoir is full, open gate 13 and close gate 14. The water from the upstream will be discharged to the downstream of the river.

[0099] Strategy 14: The current rainfall is moderate (h2). The weather forecast predicts heavy rain within the next hour, with a rainfall depth not exceeding h3. At this time, the dispatching rules are as follows: keep gates 9, 10, 11, 12, 14, 15, and 17 open. The regulating reservoir and CSO enhanced treatment facilities will collect and treat the water together. After the heavy rain occurs or the regulating reservoir is full, gate 13 will be opened. After the regulating reservoir is full, gate 14 will be closed, and the upstream water will be discharged to the downstream of the river.

[0100] Strategy 15: Current rainfall is moderate (h2). Weather forecast predicts heavy rain within the next hour, with a depth exceeding h3. The dispatching rules are as follows: Keep gates 9, 10, 11, 12, 14, 15, and 17 open. When a heavy rain is forecast, open gate 13 to fully release upstream water and reduce the water storage in the upstream culvert. When a heavy rain occurs and the culvert water level reaches 90% depth, dynamically control the opening of gate 16 to ensure water safety while controlling the overflow into the river channel.

[0101] Strategy 16: The current heavy rainfall is h3, and the weather forecast indicates that the rainfall will stop within the next hour. At this time, the dispatching rules are as follows: keep gates 9, 10, 11, 12, 13, 14, 15, and 17 open. In the later stages of the rainfall, cooperate with the culvert flushing procedure to gradually close the culvert gates.

[0102] Strategy 17: The current heavy rainfall is h3, and the weather forecast predicts light rain within the next hour, with a rainfall depth not exceeding h1. At this time, the dispatching rules are as follows: keep gates 9, 10, 11, 12, 13, 14, 15, and 17 open. After the peak flow of the rainstorm has passed, close gate 13. When the flow continues to decrease, gradually close the gates of the box culvert in conjunction with the box culvert flushing procedure, leaving one channel for entering the CSO enhanced treatment facility.

[0103] Strategy 18: Current heavy rainfall (h3), weather forecast predicts moderate rain within the next hour, with a depth not exceeding h2. Dispatch rules: Keep gates 9, 10, 11, 12, 13, 14, 15, and 17 open. Close gate 14 after the storage tank is full. After the rainfall ends, gradually close the culvert gates in conjunction with the culvert flushing procedure.

[0104] Strategy 19: Current rainfall is h3, and the weather forecast predicts continued heavy rain for the next hour. The dispatching rules are as follows: Keep gates 9, 10, 11, 12, 13, 14, 15, and 17 open. Close gate 14 once the storage tank is full. After the rainfall ends, gradually close the culvert gates in conjunction with the culvert flushing procedure. Simultaneously, control the opening of gate 16 based on the upstream inflow to reduce the amount of water entering the river channel while ensuring water safety.

[0105] Strategy 20: Current rainfall is h3, and the weather forecast predicts heavy rain within the next hour, with a depth exceeding h3. The dispatching rules are as follows: Keep gates 9, 10, 11, 12, 13, 14, 15, and 17 open. Close gate 14 once the regulating reservoir is full. Simultaneously, control the opening of gate 16 based on upstream inflow to reduce the amount of water entering the river channel while ensuring water safety.

[0106] Strategy 21: The current rainfall exceeds h3, and the weather forecast predicts that the rainfall will stop within the next hour. The dispatching rules are as follows: Keep gates 9, 10, 11, 12, 13, 14, 15, and 17 open. Close gate 14 after the regulating reservoir is full. Simultaneously, control the opening of gate 16 based on the upstream inflow, reducing the amount of water entering the river channel while ensuring water safety, until the gate is completely closed.

[0107] Strategy 22: Current rainfall exceeds h3, and the weather forecast predicts light rain within the next hour, with a depth not exceeding h1. Dispatch rules at this time: Keep gates 9, 10, 11, 12, 13, 14, 15, and 17 open. Close gate 14 after the storage tank is full. Simultaneously, control the opening of gate 16 based on upstream inflow, reducing the amount of water entering the river channel while ensuring water safety, until the gate is completely closed. After the heavy rain ends, gradually close the culvert gates in conjunction with the culvert flushing procedure, maintaining one passage to the CSO enhanced treatment facility until the rainfall gradually ceases.

[0108] Strategy 23: Current rainfall exceeds h3, and the weather forecast predicts moderate rain within the next hour, with a rainfall depth not exceeding h2. The dispatching rules are as follows: Keep gates 9, 10, 11, 12, 13, 14, 15, and 17 open. Close gate 14 once the regulating reservoir is full. Simultaneously, control the opening of gate 16 based on upstream inflow, reducing the amount of water entering the river channel while ensuring water safety, until the gate is completely closed.

Dispatch rules: Keep gates 9, 10, 11, 12, 13, 15, and 17 open. Close gate 14 after the storm water reservoir is full. Simultaneously, control the opening of gate 16 based on upstream inflow, reducing the amount of water entering the river while ensuring water safety, until the peak rainfall flow has passed, gradually closing the gate until it is completely shut off.

[0110] Strategy 25: Current rainfall exceeds h3, and weather forecast predicts continued heavy rain for the next hour. Dispatch rules at this time: Keep gates 9, 10, 11, 12, 13, 15, and 17 open. Close gate 14 after the storage tank is full. Simultaneously, control the opening of gate 16 based on upstream inflow, reducing the amount of water entering the river while ensuring water safety, until the peak rainfall flow has passed, gradually closing the gate until it is completely shut off.

[0111] In this embodiment, by solidifying the control strategy and linking it with rainfall and weather, the system can quickly find the corresponding control strategy based on data analysis results, thereby quickly controlling the sewage quality and quantity in each compartment of the box culvert. The box culvert does not accumulate silt, ensuring that the initial rainwater can reach the plant and station to the maximum extent, giving full play to the treatment capacity of each plant and station, improving economic benefits, and creating huge ecological and environmental benefits.

The system includes a prediction and early warning module, a model calculation module, an intelligent analysis module, and an intelligent decision-making module. This invention uses a hydraulic model to calculate process data of combined sewer flow from monitoring data. Based on this process data and predicted meteorological data, it analyzes the data to obtain the analysis results and corresponding control strategies. According to these strategies, it controls the opening and closing of each gate in the sewage transfer culvert, ensuring that the sewage flow velocity within each compartment of the culvert is not lower than the siltation velocity. This minimizes combined sewer overflow pollution, reduces the frequency and volume of sewage transfer culvert overflows, and also reduces the drying and compaction of sediment caused by the alternating wet and dry conditions within the culvert due to intermittent use. This improves the culvert's water conveyance capacity and reduces the occurrence of localized flooding and sewage overflows.
