Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment, specifically relating to a storage and regulation system. Background Technology

[0002] Rainwater storage tanks temporarily store peak stormwater runoff, allowing it to gradually drain after the maximum flow rate decreases. This not only mitigates stormwater flooding and promotes rainwater recycling but also prevents initial rainwater pollution of receiving water bodies and plays a positive role in drainage scheduling between drainage areas. However, impurities in rainwater easily accumulate in storage tanks, making them difficult to flush out and prone to producing odors. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a regulating system that is less prone to generating odors and has a better cleaning effect on accumulated impurities. The specific technical solution of this invention is as follows:

Detailed Implementation

[0054] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to the accompanying drawings.

[0055] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0057] like Figure 1 , 8 As shown, the storage system in this embodiment includes a storage tank body 10a, a deodorization system 20b, a collection system 30c, a flushing system 40d, a pretreatment system 50e, and a discharge system 60f.

[0058] Among them, such as Figure 2 , 3 As shown in Figures 4, 5, 6, and 7, the main body 10a of the stormwater storage tank includes a storage cavity 101a for holding rainwater and a storage discharge end 104a at the first end of the storage cavity 101a. The bottom wall of the storage cavity 101a slopes downward from the second end to the first end, and the acute angle formed is less than 5°. The bottom wall of the storage cavity 101a is provided with multiple guide walls 102a protruding along its upper surface, and the guide walls 102a are arranged in an array at intervals from the second end to the first end. The flushing system 40d includes multiple water storage chambers 401d, which are located in the storage... The diaphragm valve 402d at the top of the water chamber 401d and the air pump connected to the diaphragm valve 402d have a connected state and a closed state. When it is in the connected state, the water chamber 401d is connected to the air pump. When it is in the closed state, the water chamber 401d is sealed. The water chamber 401d is located at the second end of the accommodating cavity 101a. The bottom of the water chamber 401d is provided with a connecting port 403d that communicates with the accommodating cavity 101a. The connecting port 403d is lower than the guide wall 102a and is spaced apart from the guide wall 102a.

[0059] This embodiment enhances water flow within the storage tank by inclining the flow guide wall 102a and the bottom wall of the accommodating cavity 101a, preventing water quality deterioration and minimizing odor generation. Furthermore, the flushing system 40d, in conjunction with the inclined bottom wall of the accommodating cavity 101a, effectively cleans accumulated impurities.

[0060] like Figure 2 As shown, preferably, the upper end of the connecting port 403d is lower than the bottom wall of the accommodating cavity 101a, and the lower end of the connecting port 403d is connected to a guide slope 404d, the other end of which is connected to the bottom wall of the accommodating cavity 101a. The guide slope 404d allows for better drainage of water stored in the water storage chamber 401d and provides a better cleaning effect for accumulated impurities and sand.

[0061] Preferably, the second end of the main body 10a of the regulating tank is provided with a downwardly recessed outlet collection trough 103a, and the outlet collection trough 103a is provided with a regulating discharge end 104a. Both the outlet collection trough 103a and the regulating discharge end 104a are lower than the bottom wall of the receiving cavity 101a. The arrangement of the collection trough makes it more convenient for accumulated impurities and sand to be discharged from the receiving cavity 101a to the regulating discharge end 104a.

[0062] like Figure 8 ,9 As shown in Figures 1 and 10, this embodiment has an odor control system 20b.

[0063] The deodorization system 20b includes a collection pipe 201b disposed in the accommodating cavity 101a, a delivery pipe 205b connected to the output end of the collection pipe 201b, a filter spray unit 208b connected to the delivery pipe 205b, and an ion deodorization device 219b connected to the filter spray unit 208b. The input end of the collection pipe 201b is disposed in the accommodating cavity 101a and is used to collect odors in the accommodating cavity 101a. The output end of the collection pipe 201b passes through the odor delivery port and is connected to the input end of the filter spray unit 208b.

[0064] In use, the collection pipe 201b collects and transports the odor from the accommodating cavity 101a of the main body 10a of the storage tank to the transport pipe 205b, which then transports it to the filter spray unit 208b. The filter spray unit 208b sequentially performs dust removal filtration and ammonia removal spraying on the odor transported to it, and then transports the dust-filtered and ammonia-removed odor to the ion deodorization device 219b. The ion deodorization device 219b treats the odor and discharges it after it meets the emission standards.

[0065] Because the filter spray unit 208b can spray water that dissolves ammonia, it can spray ammonia to remove odors, effectively removing ammonia that is difficult to deodorize by ions; and because the filter spray unit 208b can also filter out ash and impurities in the odor, it can extend the cleanliness and service life of the ion deodorization device 219b.

[0066] The principle of ion deodorization technology is an advanced oxidation technology that combines the direct reaction of ion activation to decompose odor molecules with the indirect reaction of activation of other gas molecules to further decompose odor molecules. It comprehensively utilizes the destructive effect of ions on odorous substances and the oxidative removal effect of oxygen on odorous substances to remove VOCs (volatile organic compounds) such as hydrogen sulfide, ammonia, and methanethiol from odorous gases.

[0067] In a preferred embodiment, the filter spray unit 208b includes a filter device 211b and a spray device. The filter device 211b is used to filter and remove ash and impurities from the odor. Then, the spray device sprays water mist to dissolve and discharge the ammonia in the odor. The spray device includes a water supply pipe 220b, a water storage tank 221b connected to the water supply pipe 220b, a drain pipe 223b connected to the water storage tank 221b, a spray pump 224b connected to the water storage tank 221b, and an atomizing spray head 225b connected to the output end of the spray pump 224b. The atomizing spray head 225b is located above the filter device 211b. The atomizing spray head 225b is positioned so that the ammonia in the odor reacts more fully with the water. The output end of the collection pipe 201b is located below the filter device 211b. The filter device 211b separates the output end of the collection pipe 201b from the atomizing spray head 225b.

[0068] Water supply pipe 220b can be connected to the water supply network to transport water to water storage tank 221b; spray pump 224b draws water from water storage tank 221b and sprays water atomized with atomizing spray head 225b; the final sewage discharged from sewage pipe 223b is either biologically treated by biological treatment system or transported to sewage treatment plant.

[0069] Furthermore, the deodorization system 20b also includes a filter spray tower 209b. The filter spray tower is provided with a filter spray chamber 210b, a liquid outlet 213b connected to the filter spray chamber 210b, and a gas outlet 212b. The gas outlet 212b, atomizing spray head 225b, filter device 211b, the outlet of the collection pipe 201b, and the liquid outlet 213b are arranged at intervals from top to bottom. The filter device 211b is located inside the filter spray chamber 210b and divides the filter spray chamber 210b into upper and lower chambers. The gas outlet 212b and atomizing spray head 225b are located in the upper chamber, and the outlet of the collection pipe 201b and the liquid outlet 213b are located in the lower chamber. 2b is connected to the input end of the ion deodorization device 219b, the output end of the collection pipe 201b is connected to the filter spray chamber 210b, the liquid outlet 213b is located in the water storage tank 221b and is connected to the filter spray chamber 210b. The liquid outlet 213b is lower than the output end of the collection pipe 201b. The liquid outlet 213b discharges the sprayed wastewater from the filter spray chamber 210b to the water storage tank 221b. After being recycled multiple times, the wastewater is discharged from the water storage tank 221b through the sewage pipe 223b. The odor in the conveying pipe 205b is transported from the bottom of the filter spray tower 209b to the filter spray chamber 210b, and then passes through the filter device 211b, the atomizing spray head 225b and the gas output end 212b in sequence.

[0070] In a preferred embodiment, the deodorization system 20b further includes an emission unit 214b, which includes a fan 215b and a first emission pipe 218b connected to the output end of the fan 215b. The first emission pipe 218b is arranged vertically and discharges into the air. The input end of the fan 215b is connected to the output end of the ion deodorization device 219b. A gas detection device may also be installed at the input end of the fan 215b. The gas detection device detects toxic and harmful gases, such as H₂S, CO, and NH₃. After passing the test, the gases are discharged by the emission unit 214b to ensure the safety of surrounding residents.

[0071] Fan 215b is a variable frequency exhaust fan 215b. Fan 215b creates negative pressure to extract the main body 10a of the storage tank. Fan 215b is also equipped with an adjustment knob, which can adjust the operating frequency of fan 215b (between 0 and 50Hz). After adjustment, when fan 215b is started, it will run according to the set operating frequency.

[0072] The emission unit 214b also includes an emission tower 216b, which is covered by the fan 215b and the first emission pipe 218b. The top of the emission tower 216b is provided with a gas emission port. The upper opening of the first emission pipe 218b is located below the gas emission port, and the treated gas is discharged to the gas emission port. The top of the emission tower 216b is provided with a protective cover 217b, which is hinged to the top of the emission tower 216b. When exhausting, the gas is forced open by the wind and discharged from the gas emission port. When the deodorization system 20b is not working, the protective cover 217b covers the gas emission port to prevent dust from entering.

[0073] In a preferred embodiment, the delivery pipe 205b is equipped with a regulating valve 206b and a fire damper 207b; the regulating valve 206b can be adjusted automatically and manually, and is used to regulate the gas flow rate through the air inlet pipe 203b; the fire damper 207b is normally open, and when the fire damper 207b encounters a fire and the closing conditions are met, the entire deodorization system 20b will automatically shut down.

[0074] Furthermore, the deodorization system 20b also includes a controller, which is communicatively connected to the deodorization system 20b, gas detection equipment, filter spray unit 208b, regulating valve 206b, and fire damper 207b. The controller receives detection data from the gas detection equipment, controls the collection pipe 201b to collect odorous gas, controls the filter spray unit 208b to spray odorous gas and discharge wastewater, controls the gas flow rate, and controls the operating frequency of the fan 215b.

[0075] In a preferred embodiment, the deodorization system 20b further includes multiple gas detection devices located within the accommodating cavity 101a of the main body 10a of the regulating tank. These devices detect the gas within the accommodating cavity 101a. When the detected level of toxic or harmful gas exceeds a set value, the controller activates the deodorization system 20b. Furthermore, the deodorization system 20b also includes multiple air inlet pipes 203b, which are installed within the accommodating cavity 101a. Each air inlet pipe 203b has a fresh air inlet 204b communicating with the accommodating cavity 101a.

[0076] Furthermore, the collection pipe 201b consists of multiple interconnected pipes, and the collection pipe 201b has multiple air inlets 202b that communicate with the accommodating cavity 101a.

[0077] like Figure 11 , 12 As shown in 13, 14, 15, and 16, the embodiments also involve an air-shield dam 31c:

[0078] It includes: a shield dam assembly 100c, comprising a shield plate 101c, a connecting base 104c hinged to the lower end of the shield plate 101c, and an airbag protective plate 105c. The shield plate 101c forms a water-facing surface 102e and a water-repellent surface 103e opposite to the water-facing surface 102e. The airbag protective plate 105c is located on the water-repellent surface 103e of the shield plate 101c, with its upper end connected to the top of the shield plate 101c and its lower end connected to the connecting base 104c; and an airbag assembly 200c located on the water-repellent surface of the shield plate 101c. 103e, and located within the triangular area formed by the shield plate 101c and the airbag protective plate 105c, the airbag assembly 200c is used to raise and lower the shield plate 101c; the inflation unit, connected to the airbag assembly 200c, includes an inflation device 301c and a drying device 303c connected to the inflation device 301c, the drying device 303c is used to dry the gas supplied to it by the inflation device 301c, the drying device 303c is connected to the airbag assembly 200c, and supplies the dried gas into the airbag assembly 200c.

[0079] In this embodiment, the gas output from the inflation device 301c can be dried by the drying device 303c, and then the dried gas is delivered to the inside of the airbag assembly 200c. The shield dam assembly 100c raises the dam to intercept the river flow. The airbag protective plate 105c rises along with the shield dam 101c. The airbag protective plate 105c is behind the airbag assembly 200c and protects the airbag assembly 200c, preventing debris from entering the area corresponding to the lifting airbag 201c behind the back surface 103e of the shield 101c during use, which would damage the lifting airbag 201c or reduce its service life. The airbag protective plate 105c can be a rubber partition.

[0080] On the other hand, by drying the gas injected into the airbag assembly 200c, the lifespan of the airbag assembly 200c is improved, and the condensate is prevented from clogging the air inlet and outlet pipes 203c of the lifting airbag 201c to form a water seal, thus avoiding affecting the air release volume and time of the lifting airbag 201c, thereby avoiding affecting the collapse and flood discharge of the inflatable rubber dam and the air shield dam 31c.

[0081] In a preferred embodiment, the shield dam assembly 100c further includes a suppression belt 106c located on the backwater surface 103e, with its top connected to the shield plate 101c and its bottom connected to the connecting base 104c; the air shield dam 31c further includes an exhaust unit 400c for discharging gas from the airbag assembly 200c; the airbag assembly 200c includes a lifting airbag 201c and a gas connector 202c with one end connected to the lifting airbag 201c, the other end of which is connected to the exhaust unit 400c and the inflation unit 300c respectively.

[0082] Because the lifting airbag 201c relies on compressed air to support the shield plate 101c, the shield plate 101c vibrates continuously when impacted by water flow. This causes the shield plate 101c to be in a dynamic equilibrium of high-frequency vibration, reducing the service life of the lifting airbag 201c. The damping belt limits the maximum angle of deployment of the shield plate 101c during vibration and suppresses the high-frequency vibration of the shield plate 101c, thereby protecting the lifting airbag 201c.

[0083] In a preferred embodiment, the drying device 303c is a refrigerated dryer, which is a novel technology and belongs to the air source processing element of a pneumatic system. It utilizes refrigerant to exchange heat with compressed air, lowering the temperature of the compressed air to its dew point temperature, thereby achieving gas drying.

[0084] The airbag assembly 200c also includes an inlet / outlet pipe 203c and a condensate drain pipe 207c connected to the inlet / outlet pipe 203c. The condensate drain pipe 207c is used to discharge the condensate from the refrigerated dryer through the inlet / outlet pipe 203c. One end of the exhaust pipe 401c is connected to the exhaust unit 400c and the inflation unit 300c, respectively, and the other end is connected to the airbag connector 202c. The condensate drain pipe ensures the continuity of inflation and deflation of the airbag assembly 200c by discharging the condensate.

[0085] In a preferred embodiment, the condensate drain pipe 207c is arranged vertically, with its lower end connection port initially bent into a U-shape along the inner side of the shield plate 101c. The inlet and outlet pipe 203c further includes a vertical section 204c arranged vertically and a horizontal section 205c arranged horizontally. One end of the horizontal section 205c is connected to the airbag connector 202c, and the other end is connected to two of the connection ports of the tee connector 206c, respectively. The lower end connection port of the condensate drain pipe 207c is connected to the other port of the tee connector 206c, and the U-shaped portion of the condensate drain pipe 207c is lower than the horizontal section 205c and the tee connector 206c. With the above arrangement, the separation of coolant and gas can be achieved with a simple structure, reducing the cost of the entire device.

[0086] In a preferred embodiment, the upper end of the condensate drain pipe 207c is provided with a drain port 208c and a condensate valve 209c connected to the drain port 208c. The condensate valve 209c is used to control the discharge and closing of condensate from the drain port 208c, which is oriented towards the backwater surface 103e. The condensate is a relatively clean water resource, and this portion of the water can be reused through the condensate valve 209c, for example, for washing hands, flushing toilets, or cleaning construction tools. Below the drain port 208c, a drain pipe 210c is also provided, through which water used for handwashing or cleaning construction tools is discharged downstream.

[0087] In a preferred embodiment, a wave-breaking plate 107c is also connected to the upper end of the shield plate 101c. The wave-breaking plate 107c extends from the bottom to the top from the connecting end, and the acute angle formed by the wave-breaking plate 107c and the connecting base 104c is greater than the acute angle formed by the wave-breaking plate 107c and the connecting base 104c. The wave-breaking plate 107c can break up and turbulent the flood flow, preventing the entire air shield dam 31c from resonating and improving the safety factor of the air shield dam 31c.

[0088] In a preferred embodiment, the inflation unit further includes an inflation tank 302c. The gas input end of the inflation tank 302c is connected to the gas output end 212b of the inflation device 301c, and the gas output end 212b of the inflation tank 302c is connected to the gas input end of the drying device 303c. The drying device 303c is a refrigerated dryer, and the inflation device 301c is a screw compressor. The inflation tank 302c prevents the inflation device 301c from having a low preparation speed in an emergency, which would affect the raising time of the air shield dam 31c.

[0089] In a preferred embodiment, the inflation unit further includes a one-in-three-out air pipe connector 304c, with the air inlet branch pipe 307c of the air pipe connector 304c connected to the gas output end 212b of the drying device 303c; the airbag assembly 200c further includes a lifting airbag 201c and an air inlet / outlet pipe 203c connected to the lifting airbag 201c, with the air inlet / outlet pipe 203c connected in parallel with the three air outlet branch pipes 309c of the air pipe connector 304c. All are equipped with vent valves; in use, under inflation, the three vent valves of the three outlet branches 309c can be fully or partially opened, the output valve 308c of the inlet branch 307c is open, and the exhaust valve 402c is closed. The inflation device 301c and the gas storage tank 302c deliver the gas to the gas input end of the drying device 303c. After the drying device 303c dries the gas, it is input into the inlet and outlet pipes 203c through the gas pipe connector 304c, thereby realizing the raising of the air shield dam 31c.

[0090] Furthermore, the intake branch pipe 307c is equipped with an output valve 308c connected to the intake branch pipe 307c at the end near the refrigerated dryer. This valve can be either an electric butterfly valve 305c or a manual valve 306c. The air shield dam 31c also includes an exhaust unit 400c, which includes an exhaust pipe 401c and an exhaust valve 402c connected to the exhaust pipe 401c. The gas input end of the exhaust pipe 401c is connected to the intake branch pipe 307c, and this connection end is located on the side of the output valve 308c furthest from the refrigerated dryer. When it is necessary to lower the air shield dam 31c... When the dam collapses, the inflation device 301c, the gas storage tank 302c, and the drying device 303c are all closed. The three air outlet branches 309c can be fully or partially opened. The output valve 308c of the air inlet branch 307c is closed. The exhaust valve 402c is opened. Gas is discharged from the exhaust valve 402c and the exhaust port 403c. The pressure inside the lifting airbag 201c is reduced, thereby causing the air shield dam 31c to collapse. After the air shield dam 31c completely collapses, all three air outlet branches 309c's three air outlet valves are closed, and the exhaust valve 402c is closed.

[0091] Furthermore, the exhaust valve 402c and the ventilation valve include an electric butterfly valve 305c and a manual valve 306c. The electric butterfly valve 305c is used for automated management, and the manual valve 306c is used to prevent gas flow interruption in case of emergencies. The gas shield dam 31c also includes a control unit 500c and a sensor (not shown in the figure) installed on the shield dam assembly 100c. The control unit 500c is connected to the sensor, the electric butterfly valve 305c, the signal, the drying device 303c, and the inflation device 301c. The control unit 500c, the drying device 303c, and the inflation device 301c are located in the control room. The control unit 500c includes a console 501c and a control cabinet 502c. Intelligent management can be achieved through the control unit 500c.

[0092] like Figure 16 , 17 As shown in Figure 18, in this embodiment, an inlet grille 51e is placed:

[0093] It includes: a grating plate 100e, with a water-facing surface 102e formed on one side and a water-returning surface 103e formed on the side opposite to the water-facing surface 102e; a filter section 101e penetrating the water-facing surface 102e and the water-returning surface 103e at the lower end of the grating plate 100e; and a cleaning mechanism 200e, including a cleaning platform 201e located on the water-facing surface 102e and a power unit 205e connected to the cleaning platform 201e, the power unit 205e driving the cleaning platform 201e to move up and down along the water-facing surface 102e. The cleaning platform 201e has a loading state and a transport state. When the cleaning platform 201e is in the loading state, the material to be filtered located in the filter section 101e is placed on the cleaning platform 201e; when the cleaning platform 201e is in the transport state, the material to be filtered is moved upward along the water-facing surface 102e and away from the filter section 101e.

[0094] The filter section 101e of the bar screen 100e filters suspended solids, and the sludge removal mechanism 200e treats the filtered suspended solids and moves the filtered material upwards along the water-facing surface 102e and away from the filter section 101e to avoid the accumulation of suspended solids, which would affect the use and management of the inlet bar screen 51e. The filtered material refers to the suspended solids in the sewage. The suspended solids are intercepted by the filter section 101e, while the water passes through the filter section 101e through the water-facing surface 102e and the back surface 103e.

[0095] like Figure 19 , 20As shown, preferably, the bar screen 100e is provided with two opposing grooves 105e on one side of the water-facing surface 102e. The grooves 105e extend upward from the filter section 101e. The cleaning platform 201e is located between the two grooves 105e. Guide sliders 108e are provided on both sides of the cleaning platform 201e on the grooves 105e. The guide sliders 108e are slidably connected within the grooves 105e. The guide sliders 108e cooperate with the grooves 105e so that the cleaning platform 201e moves up and down in the direction of the bar screen 100e without wobbling. The cleaning platform 201e includes two fan-shaped connecting plates 202e and an arc-shaped transport plate 203e. The arc-shaped portions of the two connecting plates 202e are arranged downwards, and the lower arc-shaped portions of the connecting plates 202e are respectively connected to the two sides of the transport plate 203e located in the chute 105e. The upper ends are respectively connected to the guide slider 108e. The concave surface of the transport plate 203e is arranged upwards. When the cleaning platform 201e is in the loading state, the transport plate 203e is parallel to the water-facing surface 102e to prevent suspended solids from being pressed downwards. When the cleaning platform 201e is in the transport state, the transport plate 203e is perpendicular to the water-facing surface 102e, and its upper surface is used to support suspended solids. When in use, first place the transport plate 203e parallel to the water-facing surface 102e and at the bottom of the water flow channel 500e. Then rotate the transport plate 203e by ° and pull it upwards to collect the suspended matter in the filter section 101e on the upper surface of the transport plate 203e. Then continue to pull it out of the water.

[0096] Preferably, the power unit 205e includes a lifting rope 208e, a lifting machine 207e connected to the upper end of the lifting rope 208e, a tilting rope 210e, and a tilting machine 209e connected to the upper end of the tilting rope 210e. The tilting rope 210e and the two lifting ropes 208e are all located on the water-facing side 102e. The lower ends of the lifting ropes 208e are respectively connected to the guide sliders 108e. The guide sliders 108e are hinged to the connecting plate 202e through the hinge shaft 106e. The two lifting ropes 208e are used to drive the transport plate 203e to move up and down; the lower end of the tilting rope 210e... The conveyor plate 203e is connected to the side away from the water-facing surface 102e. Furthermore, the turning rope 210e is connected to the conveyor plate 203e through the connecting ring 107e. The lower end of the turning rope 210e is connected to the connecting ring 107e, and the connecting ring 107e is connected to the outside of the conveyor plate 203e. The distance between the connecting ring 107e and the water-facing surface 102e is greater than the distance between the hinge shaft 106e and the water-facing surface 102e. The elevator 207e simultaneously winds or lowers two lifting ropes 208e, and the turning rope 210e is used to drive the conveyor plate 203e to realize the up and down movement of the cleaning platform 201e. When the transport plate 203e needs to be flipped, the flipping machine 209e winds or lowers the flipping rope 210e, and the flipping rope 210e lifts or lowers the transport plate 203e, causing the transport plate 203e to rotate around the hinge shaft 106e. When the transport plate 203e rotates and moves away from the water-facing surface 102e, it enters the loading state. When the transport plate 203e rotates and moves closer to the water-facing surface 102e, the decontamination platform 201e is in the transport state.

[0097] Preferably, the grating plate 100e has two opposing sliding bosses 104e on its water-facing surface 102e. The sliding bosses 104e protrude from the water-facing surface 102e and extend upwards. Sliding grooves 105e are respectively provided on the opposite sides of the two sliding bosses 104e. Rollers 204e are respectively provided on both sides of the sliding grooves 105e on the cleaning platform 201e. The two rollers 204e abut against the sides of the sliding bosses 104e away from the water-facing surface 102e. The bosses and rollers 204e reduce the friction when the cleaning platform 201e moves up and down.

[0098] like Figure 21 As shown, preferably, the filter section 101e is formed by spaced-apart strip-shaped grids arranged in a vertical direction. The cleaning platform 201e is also provided with shovel teeth 211e that cooperate with the filter section 101e on the side near the water-facing surface 102e. Generally, suspended solids will adhere to the filter section 101e corresponding to the water-facing surface 102e under the action of water flow. In this embodiment, the shovel teeth 211e cooperate with the strip-shaped grids to make the suspended solids better detach from the filter section 101e.

[0099] like Figure 1As shown, the pretreatment system 50e includes an inlet bar screen 51e and a sedimentation tank 52e. The collection system 30c includes an air shield dam 31c, an intelligent diversion well 32c, and an inlet well 33c. The intelligent diversion well 32c is located at Leyuan Road on the left branch of the Tongle River. The intelligent diversion well 32c is equipped with one set each of a 4×1m rotary weir gate and a DN1000 hydraulic flow-limiting gate, along with a control system. The discharge system 60f includes a lift pump 61f, a sand pump 62f, a sand-water separator 63f, a flow meter well, an energy dissipation well, and a municipal sewage pipe. The flushing system 40d is generally a vacuum flushing system.

[0100] like Figure 17 As shown, preferably, the inlet grille 51e includes multiple water flow channels 500e and multiple cleaning ports 300e respectively connected to the water flow channels 500e. The cleaning ports 300e are located at the top of the water flow channels 500e. The grille plate 100e consists of multiple plates inserted into the water flow channels 500e through the cleaning ports 300e. The upper end of the grille plate 100e extends upward relative to the cleaning ports 300e, and the lower end abuts against the bottom of the water flow channels 500e. The filter part 101e of the grille plate 100e is arranged along the cross-section of the water flow channel 500e and faces the water flow direction. Multiple cleaning mechanisms 200e are correspondingly arranged in each water flow channel 500e. The cleaning platform 201e transports the filtered material out from the cleaning port 300e. Furthermore, the lower ends of the lifting rope 208e and the tilting rope 210e are respectively connected to the cleaning platform 201e. The lifting machine 207e and the tilting machine 209e are located above the water flow channel 500e and beside the cleaning port 300e. Furthermore, the power unit 205e also includes a mounting frame 206e, located beside the cleaning port 300e, for mounting the lifting machine 207e and the tilting machine 209e. The inlet screen 51e also includes a control unit 500c, which is electrically and signal-connected to the power unit 205e. The control unit 500c controls the lifting machine 207e to wind or lower the tilting rope 210e, and controls the tilting machine 209e to wind or lower the tilting rope 210e, thereby achieving automated management.

[0101] Preferably, the inlet grille 51e further includes an odor-proof cover 400e that covers the drain outlet 300e. The drain outlet 300e is located at the bottom of the odor-proof cover 400e, and the upper end of the grille plate 100e and the power unit 205e are both located inside the odor-proof cover 400e. The odor-proof cover 400e prevents odors inside the water flow channel 500e from escaping from the drain outlet 300e, thereby ensuring the health and safety of residents.

[0102] like Figure 22 , 23 As shown in Figures 24 and 25, the sand-water separator in this embodiment is as follows:

[0103] It includes a separator body 601f, with an upwardly inclined conveying channel 602f extending from the right end of the separator body 601f. A sand outlet 603f is opened at the bottom of the right end of the conveying channel 602f. The lower surface of the separator body 601f is an inclined surface that slopes upward from left to right. A screw conveyor is installed inside the separator body 601f, with the left end of the screw conveyor located at the bottom of the separator body 601f and the right end located inside the conveying channel 602f. A water inlet pipe 604f and a first drive device 605f are installed at the top of the separator body 601f. The water inlet pipe 604f is located to the left of the first drive device 605f. An agitator shaft 606f is installed inside the separator body 601f. The top end of the agitator shaft 606f is connected to the first drive device 605f. An agitator paddle 607f is installed on the agitator shaft 606f. The drain outlet of the water inlet pipe 604f is directly opposite the agitator shaft 606f.

[0104] In a preferred embodiment, the screw conveyor includes a screw body 608f and a second drive device 609f, the second drive device 609f being connected to the screw body 608f in a transmission manner, and the conveying channel 602f being a U-shaped groove, with the screw body 608f matching the U-shaped groove.

[0105] In a preferred embodiment, the stirring shaft 606f is vertically arranged, and the stirring paddle 607f is perpendicular to the stirring shaft 606f.

[0106] In a preferred embodiment, a shaft fixing member 610f is provided on the inner wall of the separator body 601f, and the bottom of the stirring shaft 606f is rotatably connected to the shaft fixing member 610f.

[0107] In a preferred embodiment, the top of the shaft fixing member 610f is provided with a groove, and the bottom of the stirring shaft 606f is inserted into the groove.

[0108] In a preferred embodiment, the shaft fixing member 610f is fixed to the inner wall of the separator body 601f by a plurality of support rods 612f, the plurality of support rods 612f being arranged symmetrically in pairs. Optionally, the shaft fixing member 610f is fixed to the inner sidewall of the separator body 601f by a plurality of support rods 612f.

[0109] In a preferred embodiment, the separator body 601f gradually narrows from top to bottom in the vertical direction, so that the cross-section of the separator body 601f is an inverted triangle.

[0110] In a preferred embodiment, a water outlet pipe 613f is provided on the side wall of the separator body 601f, and the water outlet pipe 613f is located at the upper end of the side wall of the separator body 601f.

[0111] In a preferred embodiment, the position where the separator body 601f connects to the conveying channel 602f is configured as a funnel-shaped transition section.

[0112] Based on the above system, the process regulation flow in this embodiment is as follows:

[0113] The air-shield dam 31c and the intelligent diversion well 32c respectively collect rainwater from the two rivers into the inlet well 33c. After passing through the inlet well 33c, the rainwater is distributed to the inlet screen 51e. The inlet screen 51e filters the rainwater and then sends it to the sedimentation tank 52e. The sedimentation tank 52e settles the sand and gravel in the rainwater and then sends it to the receiving cavity 101a of the main body 10a of the regulating tank. The deodorization system 20b deodorizes the odor in the main body 10a of the regulating tank. When the main body 10a of the regulating tank needs to be cleaned, the flushing system 40d flushes it. The lift pump 61f pumps the rainwater contained in the receiving cavity 101a and sends it to the flow meter well and the energy dissipation well in sequence before discharging it into the municipal sewage pipe. The sand pump 62f sends the pumped sludge to the sand-water separator 63f for sand-water separation. Then the separated sewage is sent to the energy dissipation well and then discharged into the municipal sewage pipe.

[0114] Vacuum flushing system 40d principle:

[0115] A vacuum flushing system is used every 40 days to flush the bottom sludge of the storage tank. After each storage cycle, the accumulated sludge and organic pollutants in the tank are cleaned to prevent the presence of odors and toxic gases. The vacuum water storage chamber is 2.0m wide, with a vacuum valve controlling the water flow at 30m³ / chamber, a water height of 5.4m, and a flushing corridor that is 5.2m wide and 96-102m long.

[0116] 1) When the storage tank starts to fill with water, the liquid level rises to the set value. The control system starts the vacuum pump and uses the vacuum pump to perform vacuum suction on the water storage chamber 401d. The vacuum pump negative pressure pipe performs vacuum suction on the water storage chamber 401d. After a certain degree of vacuum is formed, because the air pressure in the storage tank is higher than that in the water storage chamber 401d, the liquid level in the water storage chamber 401d will be raised to the set liquid level under the action of air pressure. The vacuum flushing system 40d water storage is completed.

[0117] 2) When the storage tank starts to drain, the liquid level in the storage tank gradually decreases until it is empty. Since the water storage chamber 401d is kept in a vacuum and the connection between the bottom of the water storage chamber 401d and the storage tank is a siphon structure, the liquid level inside the water storage chamber 401d remains at a high level.

[0118] 3) After the storage tank is emptied, sludge and solids will accumulate at the bottom, requiring timely flushing to prevent odor and sludge solidification. At this time, the diaphragm valve 402d at the top of the water storage chamber 401d is opened to break the vacuum, allowing the water in the water storage chamber 401d to flush the bottom sludge of the storage tank. The flushing water and bottom sludge are then pumped through the effluent collection trough 103a at the bottom of the storage tank to the sand separator 63f via the sand pump 62f and then discharged into the municipal sewage pipe.

[0119] The rinsing process of the vacuum rinsing system over 40 days:

[0120] 1) The initial regulating reservoir and water storage chamber were both empty for 401 days, such as Figure 2 As shown;

[0121] 2) The stormwater storage tank begins to fill with water, and sewage from inlet well 33c begins to flow into the stormwater storage tank, causing the tank level to rise. Figure 3 As shown:

[0122] 3) When the storage tank reaches the set liquid level, the vacuum pump starts working, extracting the air from the storage chamber 401d to create a certain degree of vacuum. Because the air pressure inside the storage tank is higher than that in the storage chamber 401d, the liquid level in the storage chamber 401d rises to the set liquid level, such as... Figure 4 As shown;

[0123] 4) When the storage tank begins to drain, the liquid level in the storage tank gradually decreases until it is empty; because a vacuum is maintained inside the water storage chamber 401d, and the connection between the bottom of the water storage chamber 401d and the storage tank is a siphon structure, the liquid level in the water storage chamber 401d remains at a high level. Figure 5 As shown;

[0124] 5) After the storage tank is emptied, sludge and solids will accumulate at the bottom, requiring timely flushing to prevent odor and sludge solidification. At this time, open the diaphragm valve 402d at the top of the water storage chamber 401d to break the vacuum, allowing the water in the storage chamber 401d to flush the bottom sludge. The flushing water and bottom sludge are discharged out of the storage tank through the effluent collection trough 103a at the bottom of the tank. Figure 6 As shown.

[0125] How to use the Collection System 30c:

[0126] 1) On a sunny day (when the rain gauge measures 0 mm)

[0127] During the recent drought, when there is sewage discharge, the rotary weir gate is fully closed and the hydraulic flow restriction gate is fully open; during the long-term dry season, when there is no sewage discharge from the box culvert, the rotary weir gate is fully open and the hydraulic flow restriction gate is fully closed.

[0128] The warning level is set at the crest of the rotating weir (33.10m), with a ground elevation of 35.30m. The bottom of the rotating weir is at an elevation of 32.10m.

[0129] 2) During rainfall: (When the rain gauge measures a cumulative rainfall of more than 2 mm in the past hour, the system enters rainfall mode.)

[0130] ① When the liquid level in the outlet well is less than the warning level of 33.10m: the rotary weir gate is fully closed and the hydraulic flow limiting gate is fully open.

[0131] ② When the water level in the outlet well reaches the warning level: the rotating weir gate is opened 1 / 3 (corresponding to a weir crest elevation of 32.77m), allowing partial flood discharge and preventing pollutants from flowing into the river. The hydraulic flow-limiting gate is half-open (corresponding to a gate bottom elevation of 32.30m).

[0132] ③ When the water level in the regulating reservoir has not reached the design water level of 28.25m and the liquid level in the outlet well reaches the warning water level of 33.10m + 300mm, the rotating weir gate is opened to 2 / 3 (corresponding to the weir crest elevation of 32.44m), allowing partial flood discharge and preventing some pollutants from flowing into the river. The hydraulic flow-limiting gate is opened to 1 / 4 (corresponding to the gate bottom elevation of 32.05m).

[0133] ④ When the water level in the regulating reservoir has not reached the design water level of 28.25m and the liquid level in the outlet well reaches the warning water level of 33.10m + 600mm, the rotating weir gate is fully opened to allow full flood discharge and prevent upstream water accumulation. The hydraulic flow restriction gate is closed.

[0134] ⑤ When the water level in the regulating reservoir reaches the design water level of 28.25m, the rotating weir gate is fully opened to allow full flood discharge and prevent upstream water accumulation, while the hydraulic flow-limiting gate is closed.

[0135] 3) Water quality compliance mode (priority before rainfall mode)

[0136] During the middle and later stages of rainfall, if the water quality meets the standard (NH3-N less than 2mg / L) for 5 consecutive minutes, the rotating weir gate will be fully opened, the hydraulic flow-limiting gate will be closed, and the qualified rainwater will be directly discharged into the river.

[0137] 4) When the rain stops: (when the increase in rainfall measured by the rain gauge within 1 hour is less than 2 mm)

[0138] Enter rain-stop mode, then return to sunny mode.

[0139] 5) Anti-backflow mode: (Priority is higher than normal mode)

[0140] When the liquid level in the downstream collection pipe is 100mm higher than the liquid level in the intelligent diversion well 32c, the hydraulic flow-limiting gate will close unconditionally. When the liquid level in the downstream collection pipe is 100mm lower than the liquid level in the intelligent diversion well 32c, the anti-backflow procedure will be exited, and the normal mode will be restored.
