Description

Technical Field

[0001] This invention relates to the field of urban drainage technology, specifically to an intelligent control method for intercepting wells, an automatic intercepting well, equipment, and medium. Background Technology

[0002] With the continuous acceleration of urbanization, urban stormwater drainage and sewage treatment have become important environmental protection and urban management issues. In urban areas, stormwater and sewage interception wells are important facilities used to intercept stormwater and sewage.

[0003] However, the inventors discovered that some urban stormwater and sewage pipe networks were built a long time ago, and some residential areas still have problems with mixed connections between stormwater and sewage pipes. In addition, the weirs in some stormwater and sewage interception wells often cannot close completely, resulting in poor interception efficiency and frequent sewage overflows. During sunny days or the initial stages of rainfall, sewage often overflows into rivers, leading to serious water pollution problems in regional river systems. It also easily causes river backflow, further exacerbating the difficulty of urban sewage treatment and negatively impacting the urban environment and water quality. Summary of the Invention

[0004] In view of this, the present invention provides an intelligent control method for intercepting wells, an automatic intercepting well, equipment and medium to solve the problem of serious river pollution caused by the poor interception effect of intercepting wells in the prior art.

[0005] In a first aspect, the present invention provides an intelligent control method for intercepting wells. The control method is applicable to automatic intercepting wells, which include: a front pool and a rear pool; one side of the front pool is connected to the urban drainage network, and the other side is connected to one side of the rear pool through a partition; the other side of the rear pool is connected to a river; a non-powered baffle weir is provided on the partition; the gate of the non-powered baffle weir is normally in a closed state to prevent river water in the rear pool from flowing into the front pool. Only when the water level in the front pool reaches the overflow level and is higher than the water level in the rear pool, the gate is pushed open under water pressure, allowing sewage in the front pool to flow into the rear pool through the weir opening.

[0006] The forebay is equipped with a first water pump and a second water pump. The flow rate of the first water pump is less than that of the second water pump. The first water pump is used to pump the sewage from the forebay to the sewage treatment plant through the sewage pipe. The second water pump is used to pump the sewage from the forebay to the rear bay through the drainage pipe or to the sewage treatment plant through the sewage pipe.

[0007] Control methods include:

[0008] Obtain the water level in the forebay and the current rainfall;

[0009] When the current rainfall is zero or within the first preset range, and the water level in the forebay is higher than the first water level but lower than the second water level, the first water pump is controlled to operate, and the sewage in the forebay is pumped to the sewage treatment plant through the sewage pipeline using the first water pump; when the water level in the forebay is higher than the second water level but lower than the third water level, the first water pump is controlled to stop operating, and the second water pump is controlled to operate; wherein, the third water level is lower than the overflow water level;

[0010] If the rainfall continues to increase and exceeds the first preset range, and the water level in the forebay is higher than the overflow level, the second water pump will be stopped, the baffle gate will be opened, and the sewage in the forebay will be discharged into the rear bay through the weir, and then discharged into the river from the rear bay.

[0011] If the water level in the forebay is higher than the third water level, determine whether the time when the rainfall is zero exceeds the preset time. If the time when the rainfall is zero exceeds the preset time, control the second water pump to work.

[0012] Based on changes in the forebay water level and current rainfall, precise and reasonable regulation is achieved using small-flow and large-flow pumps and non-powered weirs. This not only allows for the timely removal of mixed rainwater but also automatically discharges sewage, ensuring timely sewage treatment, effectively preventing sewage overflow, and guaranteeing river water quality. By promptly activating pumps and deactivating weirs according to rainfall and forebay water level changes, efficient discharge and interception of sewage within the interception well are achieved, effectively avoiding the problem of poor interception performance in traditional interception wells. Furthermore, this embodiment uses non-powered weirs to prevent backflow of river water, ensuring urban environment and water quality. Moreover, it intelligently determines when to activate pumps and deactivate weirs, achieving automated and intelligent drainage management, reducing manual intervention, lowering management costs, and improving urban sewage treatment efficiency and water resource protection levels. This is of great significance for improving the urban environment and protecting water quality.

[0013] In one alternative implementation, the control method further includes detecting pollution indicators of the wastewater in the forebay.

[0014] In one alternative implementation, when the second water pump is in operation, it is determined whether the wastewater indicators in the forebay are up to standard.

[0015] If the pollution indicators are within acceptable limits, the wastewater from the forepool is pumped to the rearpool through the drainage pipe using the second water pump.

[0016] If the pollution indicators fail to meet the standards, the second water pump is used to pump the sewage from the forebay to the sewage treatment plant through the sewage pipeline.

[0017] Based on the water level and quality in the interception well, the flow direction can be intelligently controlled to adapt to different rainfall conditions and changes in sewage load, thereby improving interception efficiency, reducing the impact of pollutants on the water environment, and providing strong support for urban sewage management and water resource protection.

[0018] In one optional implementation, a second water pump is used to pump the wastewater from the forebay to the rearbay through a drainage pipe, including:

[0019] Controls the opening and closing of drainage pipe valves; the drainage pipe valves are located inside the drainage pipes and are used to control the flow and interruption of drainage.

[0020] The wastewater from the forebay is pumped to the wastewater treatment plant via a second water pump through a wastewater pipeline, including:

[0021] These valves control the opening and closing of sewage pipe valves. They are located inside the sewage pipes and are used to control the flow and interruption of sewage.

[0022] Based on real-time water quality data, the system automatically determines whether the discharge quality requirements are met, dynamically adjusts the discharge direction, and selects to discharge water into rivers or sewage treatment plants, thereby treating sewage more flexibly and reducing the negative impact on the aquatic environment.

[0023] In one alternative implementation, the current rainfall is obtained by detecting a rain gauge located near the city's storm drains.

[0024] Secondly, an automatic interception well is provided, applicable to the above-mentioned control method. The automatic interception well includes:

[0025] The forebay and the rearbay are connected. One side of the forebay is connected to the city's drainage network, and the other side is connected to one side of the rearbay via a partition. The other side of the rearbay is connected to the river. A non-powered baffle is installed on the partition. The gate of the non-powered baffle is usually closed to prevent the river water in the rearbay from flowing into the forebay. Only when the water level in the forebay reaches the overflow level and is higher than the water level in the rearbay will the gate be pushed open by the water pressure, allowing the sewage in the forebay to flow into the rearbay through the weir.

[0026] The first and second water pumps are both located inside the forebay. The first water pump is used to pump the sewage from the forebay to the sewage treatment plant through the sewage pipe. The second water pump is used to pump the sewage from the forebay to the rear bay through the drainage pipe or to the sewage treatment plant through the sewage pipe. The flow rate of the first water pump is less than that of the second water pump.

[0027] The forebay level gauge is installed inside the forebay and is used to detect the water level in the forebay.

[0028] The rear tank level gauge is installed inside the rear tank and is used to detect the water level in the rear tank.

[0029] Water quality monitoring equipment is installed inside the forebay to detect pollution indicators of the wastewater in the forebay;

[0030] Rain gauges are installed near urban storm drains to detect current rainfall.

[0031] Wastewater pipeline valves are installed inside the wastewater pipelines connected to the first and second water pumps to control the flow and interruption of wastewater.

[0032] A drain pipe valve is installed inside the drain pipe connected to the second water pump and is used to control the flow and interruption of the drain pipe.

[0033] The controller is electrically connected to the first water pump, the second water pump, the forepool level gauge, the rearpool level gauge, the water quality monitoring equipment, the rain gauge, the sewage pipe valve, and the drainage pipe valve.

[0034] In one alternative implementation, the controller includes:

[0035] The acquisition module is used to acquire the water level in the forebay and the current rainfall.

[0036] The control module is used to control the first water pump to start when the current rainfall is zero or within a first preset range and the water level in the forebay is higher than the first water level and lower than the second water level; or to control the first water pump to stop working and control the second water pump to start when the water level in the forebay is higher than the second water level and lower than the third water level.

[0037] It is also used to control the second water pump to stop working when the rainfall continues to increase, exceeds the first preset range, and the water level of the forebay is higher than the third water level, so that the sewage in the forebay is discharged into the rear bay through the baffle weir gate, and then discharged into the river from the rear bay.

[0038] The time judgment module is used to determine whether the time when the rainfall is zero exceeds the preset time when the water level in the forebay is higher than the third water level.

[0039] If the rainfall is zero for more than a preset time, the control module will activate the second water pump.

[0040] In one alternative implementation, the control module further includes:

[0041] The indicator judgment module is used to determine whether the pollution indicators of the sewage in the forebay are up to standard when the second water pump is working.

[0042] The control module is also used to control the opening and closing of the drainage pipe valve and the sewage pipe valve when the pollution indicators are qualified, and to use the second water pump to pump the sewage from the forebay to the rearbay through the drainage pipe; it is also used to control the opening and closing of the sewage pipe valve and the closing of the drainage pipe valve when the pollution indicators are not qualified, and to use the second water pump to pump the sewage from the forebay to the sewage treatment plant through the sewage pipe.

[0043] Thirdly, the present invention provides a computer device, comprising: a memory and a processor, wherein the memory and the processor are communicatively connected to each other, the memory stores computer instructions, and the processor executes the computer instructions to perform the intelligent control method for diversion wells described in the first aspect or any corresponding embodiment thereof.

[0044] Fourthly, the present invention provides a computer-readable storage medium storing computer instructions for causing a computer to execute the intelligent control method for a diversion well according to the first aspect or any corresponding embodiment described above.

Detailed Implementation

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] In many traditional stormwater and sewage interception wells (stormwater and sewage interception wells), the following shortcomings exist:

[0053] 1. Poor interception effect: Due to the continuous inflow of sewage, the baffles in traditional interception wells often cannot be completely closed, resulting in poor interception effect, inability to effectively control the flow direction of sewage, and affecting the water quality of the river.

[0054] 2. Frequent sewage overflows: Due to the unsatisfactory interception effect, sewage often overflows in the interception well, which seriously affects the urban environment and water quality.

[0055] 3. River backflow problem: The weir cannot be completely closed, which may allow external river water to backflow into the interception well, exacerbating the difficulty of urban sewage treatment.

[0056] 4. Inflexible management of rainwater outfalls: Traditional intercepting wells lack intelligent control, relying solely on manual judgment to determine when to start the water pump and close the baffle weir, which cannot adapt to different rainfall conditions and changes in sewage load.

[0057] In view of this, according to an embodiment of the present invention, an embodiment of a smart control method for intercepting wells is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0058] This embodiment provides an intelligent control method for intercepting wells. The control method is applicable to automatic intercepting wells, and the automatic intercepting well refers to... Figure 1 As shown in Figure 2, the automatic interception well includes: a front pool 1 and a rear pool 2; one side of the front pool 1 is connected to the urban drainage network 3, and the other side is connected to one side of the rear pool 2 through a partition 4; the other side of the rear pool 2 is connected to the river channel 5; a non-powered baffle 41 is installed on the partition 4; the gate of the non-powered baffle 41 is normally in a closed state to prevent the river water in the rear pool 2 from flowing into the front pool 1. Only when the water level of the front pool 1 reaches the overflow level and is higher than the water level of the rear pool 2, the gate is pushed open under water pressure, so that the sewage in the front pool 1 flows into the rear pool 2 through the weir opening;

[0059] The forebay 1 is equipped with a first water pump 11 and a second water pump 12. The flow rate of the first water pump 11 is less than that of the second water pump 12. The first water pump 11 is used to pump the sewage from the forebay 1 to the sewage treatment plant through the sewage pipe 13. The second water pump 12 is used to pump the sewage from the forebay 1 to the rearbay 2 through the drainage pipe 14 or to the sewage treatment plant through the sewage pipe 13. The forebay 1 is also equipped with a forebay level gauge 15 for detecting the water level of the forebay 1. The rearbay 2 is equipped with a rearbay level gauge 21 for detecting the water level of the rearbay 2.

[0060] A flowchart of the intelligent control method for intercepting wells according to an embodiment of the present invention is shown below. Figure 3 As shown, the control methods include:

[0061] Step S101: Obtain the water level of the forebay 1 and the current rainfall, and also obtain the water level of the aftbay 2. The water level of the forebay 1 can be obtained by the forebay level gauge 15, and the water level of the aftbay 2 can be obtained by the aftbay level gauge 21.

[0062] In some alternative implementations, the current rainfall is obtained by detecting it with a rain gauge located near the city's storm drains. Based on the current rainfall, the current weather conditions can be determined, such as sunny, light rain, moderate rain, heavy rain, torrential rain, extremely heavy rain, or exceptionally heavy rain.

[0063] Step S102: When the current rainfall is zero or within a first preset range, and the water level of the forebay 1 is higher than the first water level but lower than the second water level, the first water pump 11 is started to pump the sewage from the forebay 1 to the sewage treatment plant through the sewage pipe 13. When the current rainfall is zero or within a first preset range, and the water level of the forebay 1 is higher than the second water level but lower than the third water level, the first water pump 11 is stopped, and the second water pump 12 is started; wherein the third water level is lower than the overflow water level.

[0064] Light rain typically amounts to less than 10mm of rainfall, while heavy rain ranges from 50mm to 99.9mm. Therefore, in this embodiment, a first preset range can be set based on the typical rainfall amount in a city. For example, the first preset range can be set to (0, 10) or (0, 50). When the current rainfall is zero, it indicates that there is no rainfall at this time, meaning the current weather is sunny, cloudy, or the rain has just ended.

[0065] In this embodiment, urban stormwater and sewage generally enter the intercepting well forebay 1 through urban stormwater pipes. If the current rainfall is zero, that is, when the current weather is sunny or cloudy, the sewage in the forebay 1 is generally less, mostly accumulated sewage, and the water quality is poor. When the water level in the forebay 1 is higher than the first water level but lower than the second water level, the sewage is directly pumped to the municipal sewage pipe 13 using a first water pump with a smaller flow rate, and then transported to the sewage treatment plant. At this time, the non-powered baffle 41 is in a normally closed state, effectively preventing sewage overflow and river backflow. The first, second, and third water levels can be set according to the capacity of the intercepting well forebay 1. For example, the first water level can be 0.05m above the bottom of the pipe, the second water level can be 0.2m above the bottom of the pipe, and the third water level can be 0.6m above the bottom of the pipe, etc.

[0066] If the rainfall has ended or is about to end, the water in the forebay 1 may be settled sewage. If it is in the initial stage of rainfall, the water in the forebay 1 is mostly sewage from washing the ground. If the water level in the forebay 1 is lower than the second water level, the sewage will still be pumped directly to the sewage treatment plant using the first water pump 11 with a smaller flow rate.

[0067] If the current weather is likely to be a period of continuous light to heavy rain or torrential rain, the sewage in forebay 1 will gradually increase, and the water quality will slowly improve. If the water level in forebay 1 is still higher than the first water level but lower than the second water level, the sewage will still be directly pumped to the sewage treatment plant using the first water pump 11, which has a relatively small flow rate. If the water level in forebay 1 starts to be higher than the second water level but lower than the third water level, and the water volume in forebay 1 is large, the second water pump 12 will be started to perform high-flow drainage, and the first water pump 11 will be shut off.

[0068] When the water level in the forebay 1 is higher than the first water level but lower than the second water level, or when the water level in the forebay 1 is higher than the second water level but lower than the third water level, the weir gate remains closed, which can effectively prevent sewage overflow and river backflow. Furthermore, by using the first water pump 11 and the second water pump 12 to discharge the accumulated sewage in advance, it is beneficial to improve drainage efficiency and the quality of sewage discharged into the river.

[0069] In step S103, when the rainfall continues to increase and exceeds the first preset range, and the water level of the forebay 1 is higher than the overflow level, the second water pump 12 is controlled to stop working, the baffle gate is opened, and the sewage in the forebay 1 is discharged into the rear bay 2 through the weir, and then discharged into the river 5 from the rear bay 2.

[0070] When the water level of the forebay 1 is higher than the second water level but lower than the third water level, the sewage in the forebay 1 is pumped to the sewage treatment plant or the back bay 2 by the high-flow second water pump 12. Therefore, as the water level continues to increase, the water quality in the forebay 1 improves and gradually meets the conditions for discharge into the river channel 5.

[0071] In this embodiment, the overflow water level of the non-powered baffle weir 41 is the water level at which the weir gate can be pushed open. When the rainfall continues to increase and the water level of the forebay 1 exceeds the overflow water level, the first water pump 11 and the second water pump 12 stop working, and the baffle weir gate is opened under the action of water pressure, and the sewage in the forebay 1 is discharged into the rear bay 2 through the baffle weir gate, and then discharged into the river channel 5 from the rear bay 2.

[0072] After overflow, when the water level in the front pool 1 is the same as that in the rear pool 2, the baffle weir automatically closes under the action of the counterweight cylinder. The baffle weir remains in a normally closed state to prevent backflow of water from the external river.

[0073] Step S104: If the water level of the forebay 1 is higher than the third water level, determine whether the time when the rainfall is zero exceeds a preset time. If the time when the rainfall is zero exceeds the preset time, control the second water pump 12 to work.

[0074] Because some surface water flows into the forebay 1 through the city's drainage network 3 after rainfall ends, the water level in the forebay 1 will constantly change. To prevent the weir gate from frequently opening and closing, and the second water pump 12 from frequently switching between starting and stopping, when the water level in the forebay 1 is higher than the third water level, it is necessary to determine whether the time of zero rainfall exceeds a preset time, such as 12 hours or 24 hours. Taking a preset time of 12 hours as an example, if the time of zero rainfall lasts for 12 hours, it is determined that the rainfall has ended. At this time, the second water pump 12 is restarted until it is lower than the second water level, and then the first water pump 11 starts working.

[0075] After the rainfall ends, the second water pump 12 can ensure that the automatic interception well can promptly remove mixed rainwater within a certain period of time after the rainfall, such as 12 to 24 hours, so that the automatic interception well can return to its normal interception state on sunny days.

[0076] In this embodiment, based on changes in the water level of the forebay 1 and the current rainfall, precise and reasonable regulation is achieved using small-flow pumps, large-flow pumps, and a non-powered weir 41. This not only allows for the timely removal of mixed rainwater but also automatically discharges sewage, ensuring timely sewage treatment, effectively preventing sewage overflow, and guaranteeing the water quality of river 5. By promptly activating the pumps and deactivating the weir according to changes in rainfall and the water level of the forebay 1, efficient discharge and interception of sewage within the interception well are achieved, effectively avoiding the problem of poor interception performance in traditional interception wells. Furthermore, the use of a non-powered weir 41 in this embodiment prevents backflow of river water, ensuring the urban environment and water quality. Moreover, the system intelligently determines when to activate the pumps and deactivate the weir, achieving automated and intelligent drainage management, reducing manual intervention, lowering management costs, and improving urban sewage treatment efficiency and water resource protection levels. This is of great significance for improving the urban environment and protecting water quality.

[0077] In some optional implementations, the intelligent control method further includes detecting pollution indicators of the wastewater in the forebay 1. These pollution indicators include COD, NH4, conductivity, and SS.

[0078] In some alternative implementations, when the second water pump 12 is activated, it is determined whether the wastewater indicators in the forebay 1 are up to standard.

[0079] If the pollution indicators are within acceptable limits, the wastewater from the forepool 1 is pumped to the rearpool 2 through the drainage pipe 14 using the second water pump 12.

[0080] If the pollution indicators are not up to standard, the second water pump 12 is used to pump the sewage from the forebay 1 to the sewage treatment plant through the sewage pipe 13.

[0081] If the water level in pool 1 is higher than the second water level but lower than the third water level, the corresponding weather may be that the rainfall has just ended or that it is currently raining but the conditions for opening the weir gate have not yet been met. In this case, it is necessary to assess the water quality in pool 1 to determine whether to discharge it into the sewage treatment plant or into pool 2, in order to alleviate the treatment pressure on the sewage treatment plant and improve the quality of the drainage.

[0082] In this embodiment, the direction of water flow can be intelligently controlled according to the water level and water quality in the interception well to adapt to different rainfall conditions and changes in sewage load, thereby improving interception efficiency, reducing the impact of pollutants on the water environment, and providing strong support for urban sewage management and water resource protection.

[0083] In some alternative embodiments, the wastewater from the forepool 1 is pumped to the rearpool 2 through the drainage pipe 14 using the second water pump 12, including:

[0084] The drain pipe valve 141 is opened and the sewage pipe valve 131 is closed; wherein, the drain pipe valve 141 is installed inside the drain pipe 14 and is used to control the flow and interruption of the drain pipe 14.

[0085] The wastewater from the forebay 1 is pumped to the wastewater treatment plant via the wastewater pipeline 13 using the second water pump 12, including:

[0086] The sewage pipe valve 131 is used to open and close the drainage pipe valve 141. The sewage pipe valve 131 is installed inside the sewage pipe 13 and is used to control the flow and interruption of sewage in the sewage pipe 13.

[0087] The intercepting well control method provided in this embodiment can intelligently control the water level and flow direction in the intercepting well to adapt to different rainfall conditions and changes in sewage load, improve interception efficiency, and reduce the impact of pollutants on the water environment.

[0088] When the water level in the foreground pool 1 is higher than the second water level but lower than the third water level, it generally indicates that rainfall has just ended or is just beginning. At this time, the water quality of the water accumulated in the foreground pool 1 is unknown. Online water quality monitoring equipment can be used to achieve automatic differentiated drainage. That is, when the water quality in the foreground pool 1 meets the discharge standards, the drainage pipe valve 141 opens, discharging the water from the foreground pool 1 into the rear pool 2, and then from the rear pool 2, the water is discharged into the river 5. When the water quality monitoring data does not meet the discharge requirements, the sewage pipe valve 131 opens, discharging the water from the foreground pool 1 into the municipal sewage network, and then from the municipal sewage network to the sewage treatment plant. This automatically adjusts the drainage direction, achieving intelligent drainage management. This intelligent control method can improve drainage efficiency, reduce the impact of pollutants on the water environment, and provide strong support for urban sewage management and water resource protection. This intelligent control method can improve urban sewage treatment efficiency, reduce the impact of pollutants on the water environment, and contribute to the sustainable development of urban water resources.

[0089] In this embodiment, the system automatically determines whether the water quality requirements for external discharge are met based on real-time water quality data, dynamically adjusts the discharge direction, and selects to discharge the water to River 5 or the sewage treatment plant, thereby treating sewage more flexibly and reducing the negative impact on the aquatic environment.

[0090] In some alternative implementations, controlling the first water pump 11 to pump the sewage from the forebay 1 to the sewage treatment plant through the sewage pipe 13 includes: controlling the first water pump 11 to start while simultaneously controlling the sewage pipe valve 131 to open.

[0091] In this embodiment, by controlling the sewage pipeline valve 131, the sewage in the forebay 1 can be discharged into the sewage treatment plant, thereby improving the quality of the urban water environment and also improving the subsequent interception efficiency and drainage efficiency.

[0092] This embodiment also provides an automatic interception well, which is applicable to the above-described intelligent control method for interception wells, referring to... Figure 1 or Figure 2 As shown, the automatic interception well includes:

[0093] Forepool 1 and Rearpool 2; One side of Forepool 1 is connected to the urban drainage network 3, and the other side is connected to one side of Rearpool 2 through partition 4; The other side of Rearpool 2 is connected to the river channel 5; A non-powered baffle 41 is installed on partition 4; The gate of the non-powered baffle 41 is usually in a closed state to prevent the river water in Rearpool 2 from flowing into Forepool 1. Only when the water level of Forepool 1 reaches the overflow level and is higher than the water level of Rearpool 2, the gate is pushed open under water pressure, so that the sewage in Forepool 1 flows into Rearpool 2 through the weir opening;

[0094] The first water pump 11 and the second water pump 12 are both installed inside the forepool 1. The first water pump 11 is used to pump the sewage from the forepool 1 to the sewage treatment plant through the sewage pipe 13. The second water pump 12 is used to pump the sewage from the forepool 1 to the rear pool 2 through the drainage pipe 14 or to the sewage treatment plant through the sewage pipe 13. The flow rate of the first water pump 11 is less than the flow rate of the second water pump 12.

[0095] The forebay level gauge 15 is installed inside the forebay 1 and is used to detect the water level in the forebay 1.

[0096] The rear pool level gauge 21 is installed inside the rear pool 2 and is used to detect the water level in the rear pool 2.

[0097] Water quality monitoring equipment (not shown in the figure) is installed inside the forebay 1 and is used to detect pollution indicators of the wastewater in the forebay 1.

[0098] Rain gauges (not shown in the diagram) are installed near urban storm drains to detect current rainfall.
