Description

Technical Field

[0001] This invention belongs to the field of wastewater storage technology, specifically relating to an overflow wastewater storage device and its usage method. Background Technology

[0002] Combined sewer overflow (CSO) pollution, also known as combined sewer overflow, refers to the phenomenon in urban drainage systems where, during dry weather, the sewage flow in the pipes is relatively small and can be transported to downstream wastewater treatment plants for treatment through interceptor pipes. However, during rainy weather, the flow exceeds the design capacity of the pipe network, resulting in overflow. This overflow carries with it pollutants that have accumulated in the pipe system during dry weather, flowing directly into surrounding water bodies without any treatment and causing pollution. Urban non-point source pollution from CSO has become an undeniable indicator in urban water pollution control. The pollutants discharged into water bodies by combined sewer overflows seriously threaten the aquatic ecosystem, significantly impacting the restoration of water body functions and the regulation of ecological balance.

[0003] To effectively address the pollution problem caused by combined sewer overflows, rapid purification facilities such as stormwater storage tanks are needed to achieve both storage and primary treatment. However, existing stormwater storage tanks are generally just simple tanks with only water storage, discharge, and basic wastewater treatment functions. Especially during the initial stages of rainfall, rainwater, sewage from upstream pipes, and pollutants from the atmosphere and surface are all introduced into the storage tanks. These tanks are unable to effectively treat these substances, leading to their direct introduction into wastewater treatment plants and causing an overload on these plants. Furthermore, over long periods of use, a large amount of sludge easily accumulates on the bottom of the storage tanks. If this sludge is not cleaned in a timely manner, it will affect the normal operation of the storage tanks.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide an overflow sewage storage device and its usage method.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide an overflow sewage storage device and its usage method, which can solve the problems of poor storage effect and difficulty in cleaning the sludge at the bottom of existing storage tanks.

[0007] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution:

[0008] An overflow sewage storage device includes: a storage tank body, multiple columns, a suspended capture mechanism, multiple capture-type cleaning mechanisms, and an auxiliary capture mechanism;

[0009] The main body of the storage tank is provided with a first partition and a second partition. A first compartment, a second compartment, and a third compartment are formed between the first partition, the second partition, and the inner wall of the main body of the storage tank. An inlet pipe and an outlet pipe are connected to the main body of the storage tank. The inlet pipe is connected to the first compartment, and the outlet pipe is connected to the third compartment.

[0010] Multiple of the aforementioned columns are installed within the first compartment pool;

[0011] The suspension capture mechanism is located in the first compartment pool and is slidably mounted on the plurality of columns;

[0012] Multiple of the aforementioned capture-type cleaning mechanisms are installed within the suspended capture mechanism;

[0013] The auxiliary capture mechanism is installed on the suspended capture mechanism and covers the capture-type cleaning mechanism;

[0014] During rainfall, the suspended capture mechanism is suspended above the surface of the first compartment pool. Under the combined action of the suspended capture mechanism, the capture-type cleaning mechanism, and the auxiliary capture mechanism, suspended solids and pollutants in the first compartment pool are intercepted. When cleaning the bottom of the first compartment pool, the suspended capture mechanism descends to the bottom of the column and uses multiple capture-type cleaning mechanisms to clean the bottom of the first compartment pool.

[0015] In one or more embodiments of the present invention, a connecting pipe is installed on both the first partition and the second partition, and a control valve is installed on the connecting pipe. The first compartment pool, the second compartment pool and the third compartment pool are connected to each other through the connecting pipe. When the control valve is opened, the liquid in the first compartment pool, the second compartment pool and the third compartment pool will flow to each other to discharge the liquid in the first compartment pool, the second compartment pool and the third compartment pool.

[0016] The main body of the storage tank is equipped with multiple sewage pipes. The first, second, and third compartments are connected to the outside through the sewage pipes, which can discharge the liquid in the first, second, and third compartments and introduce it into the sewage treatment plant.

[0017] In one or more embodiments of the present invention, a first filter screen is installed on the top wall of the first partition, and the first filter screen is used to filter suspended matter in the liquid.

[0018] The height of the first partition and the first filter screen is greater than the height of the second partition. When the liquid in the second compartment is discharged through the second partition, the liquid in the first compartment still enters the second compartment through the first filter screen, so as to ensure the filtering effect of the first filter screen on the liquid.

[0019] A second filter screen is connected between the end of the first filter screen and the side wall of the second partition, and a third filter screen is connected between the second partition and the inner top wall of the regulating tank. Both the second and third filter screens are used to filter suspended solids in the liquid.

[0020] In one or more embodiments of the present invention, a straight pipe is installed on the top wall of the first compartment pool, a plurality of nozzles are installed on the straight pipe, and a cleaning pipe is connected to the straight pipe. The cleaning pipe passes through the main body of the regulating tank. When the cleaning pipe is connected to a clean water supply end, clean water can enter the straight pipe and be sprayed onto the first compartment pool through the nozzles to clean the bottom of the first compartment pool.

[0021] In one or more embodiments of the present invention, the length of the column is less than the height of the first partition plate, which is used to limit the floating height of the suspension plate so as to ensure that some of the liquid in the first compartment pool can enter the mounting platform and the conical groove.

[0022] The column sidewall is fixedly connected to a first support ring for supporting the suspension plate. When there is no liquid in the first compartment pool, the suspension plate contacts the first support ring, and the brush bristles can contact the bottom wall of the first compartment pool so as to clean the bottom of the first compartment pool using the brush bristles.

[0023] The top wall of the column is fixedly connected to a first limiting post, which is used to limit the suspension plate and prevent the suspension plate from sliding completely out of the column.

[0024] In one or more embodiments of the present invention, the suspension capture mechanism includes a suspension plate, a pair of buoyancy-enhancing elements and a mounting platform are mounted on the suspension plate, the pair of buoyancy-enhancing elements are symmetrical about the mounting platform, the suspension plate and the buoyancy-enhancing elements are able to suspend above the liquid, and the mounting platform is used to mount multiple capture-type cleaning mechanisms;

[0025] The mounting platform is embedded with a plurality of evenly distributed oscillating columns, each of which corresponds to a plurality of capture-type cleaning mechanisms. The oscillating columns are used to accommodate oscillating balls.

[0026] A guide tube is connected to the oscillating column. One end of the guide tube passes through the mounting platform and the suspension plate, and the liquid in the conical groove can be discharged through the guide tube.

[0027] Both the suspension plate and the mounting platform are provided with interconnected channels, through which the liquid in the first compartment pool can enter between the mounting platform and the cover plate.

[0028] In one or more embodiments of the present invention, the capture-type cleaning mechanism includes a universal ball, and the suspension plate is provided with a rotating groove that matches the universal ball. When the oscillating ball is impacted by liquid, it can move randomly under the action of the universal ball.

[0029] The omnidirectional ball is fixedly connected to a mounting column and a connecting column. One end of the mounting column passes through the suspension plate. Multiple bristles are staggered and connected to the side wall of the mounting column. The bristles are located on the lower side of the suspension plate. When the oscillating ball moves irregularly, the mounting column and the bristles are driven to swing irregularly through the connecting column and the omnidirectional ball. The irregularly swinging bristles can capture suspended matter in the liquid and are also used to clean the bottom of the first compartment pool.

[0030] In one or more embodiments of the present invention, one end of the connecting column is disposed inside the oscillating column, and the end of the connecting column away from the universal ball is connected to an oscillating ball. The oscillating column is provided with a conical groove that matches the oscillating ball. When the liquid flows in the conical groove, the liquid can impact the oscillating ball and cause the oscillating ball to move randomly.

[0031] In one or more embodiments of the present invention, the auxiliary capture mechanism includes a cover plate that covers the mounting platform and is capable of capturing suspended matter in the liquid;

[0032] The cover plate is connected to a telescopic belt, and the side wall of the telescopic belt is provided with multiple leakage holes. When the cover plate is away from the mounting platform, the telescopic belt is pulled and stretched, the diameter of the leakage holes becomes larger, and the liquid between the mounting platform and the cover plate can be discharged through the leakage holes, while larger suspended particles are intercepted by the cover plate.

[0033] A fixing ring is connected to the telescopic belt. The fixing ring surrounds the mounting platform and is fixedly connected to the suspension plate, which is used to fix the cover plate and the telescopic belt to the outside of the mounting platform.

[0034] The top wall of the cover plate is provided with multiple through holes, through which liquid inside the mounting platform can be discharged, and at the same time, cleaning water can enter the mounting platform through the through holes.

[0035] A method of using the overflow sewage storage device includes the following steps:

[0036] S1. During rainfall, initial rainwater, sewage from upstream pipes, and pollutants from the atmosphere and surface enter the first compartment pool through the inlet pipe.

[0037] S2. If it continues to rain outside, the water level in the first compartment will gradually increase, and the suspension plate will float up along the column and always float on the top of the liquid.

[0038] S3. When the suspension plate moves to the end of the column, the suspension plate stops rising. Some of the liquid in the first compartment pool will enter between the mounting platform and the cover plate through the channel. The cover plate is impacted by the liquid and moves away from the mounting platform. At this time, the telescopic belt is pulled and stretched, the diameter of the leakage hole becomes larger, and the liquid between the mounting platform and the cover plate will be discharged through the leakage hole and the through hole respectively.

[0039] S4. Some of the liquid in the first compartment will also enter the conical groove through the guide pipe and impact the oscillating ball. Under the action of the connecting column and the universal ball, the oscillating ball moves randomly in the conical groove. The randomly moving oscillating ball drives the mounting column and the brush to swing randomly under the suspension plate. The randomly swinging brush can capture suspended matter and pollutants in the liquid. At the same time, since the suspension plate floats on the upper side of the first compartment, the suspension plate can also block suspended matter in the liquid.

[0040] S5. When the liquid level in the first compartment exceeds the first partition, the liquid enters the second compartment through the first filter screen, and the first filter screen is used to further filter the suspended matter in the liquid.

[0041] S6. When the liquid level in the second compartment exceeds the second baffle, the liquid enters the third compartment through the third filter screen. The second and third filters can continue to filter the suspended solids in the liquid. Finally, the liquid in the third compartment enters the sewage treatment plant through the drain pipe.

[0042] S7. If the rainfall stops, the liquid in the first, second and third compartments will be discharged through the sewage pipe and introduced into the sewage treatment plant.

[0043] S8. When it is necessary to clean the bottom of the first compartment pool, connect the cleaning pipe to the clean water supply end. The clean water is sprayed onto the first compartment pool through the nozzle on the straight pipe. Some of the clean water sprayed by the nozzle will fall directly to the bottom of the first compartment pool, and some clean water will enter between the mounting platform and the cover plate through the through hole.

[0044] S9. Some of the clean water inside the installation platform is discharged directly to the bottom of the first compartment tank through the channel, and some of the clean water enters the conical groove and impacts the vibrating ball, which causes the installation column and brush bristles to swing irregularly. The irregularly swinging brush bristles can clean the dirt at the bottom of the first compartment tank. The dirt and sewage at the bottom of the first compartment tank can be discharged through the sewage pipe and introduced into the sewage treatment plant.

[0045] Compared with the prior art, the overflow sewage storage device and its usage method of the present invention can greatly improve the storage capacity of the storage tank, effectively treat the sewage entering the storage tank, reduce the overload impact of sewage on the sewage treatment plant, and thus solve the problem of overload operation of the sewage treatment plant. At the same time, it can also realize the convenient cleaning of sewage at the bottom of the storage tank, and avoid the sewage at the bottom of the tank from affecting the water storage tank.

Detailed Implementation

[0064] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0065] like Figures 1 to 15 As shown, an overflow sewage storage device according to one embodiment of the present invention includes a storage tank body 1, multiple columns 2, a suspended capture mechanism 3, multiple capture-type cleaning mechanisms 4, and an auxiliary capture mechanism 5.

[0066] During rainfall, the suspended capture mechanism 3 remains suspended on the surface of the first compartment. Through the combined action of the suspended capture mechanism 3, the capture-type cleaning mechanism 4, and the auxiliary capture mechanism 5, it can trap suspended solids and pollutants in the first compartment, reducing their flow into the second compartment, the third compartment, or the wastewater treatment plant. This alleviates the burden on the wastewater treatment plant. Figure 12 The diagram shows a liquid flow.

[0067] Simultaneously, in the initial stage of rainfall, rainwater, sewage from upstream pipes, and pollutants from the atmosphere and surface will first enter the first compartment pool through the inlet pipe 103, resulting in a relatively large amount of sewage at the bottom of the first compartment pool. Therefore, when it is necessary to clean the bottom of the first compartment pool, the liquid in the first compartment pool is emptied using the drain pipe 108, allowing the suspended capture mechanism 3 to descend to the bottom of the column 2. At this time, the capture-type cleaning mechanism 4 can contact the bottom of the first compartment pool. Then, clean water is injected through the straight pipe 109, and with the cooperation of multiple capture-type cleaning mechanisms 4, the bottom of the first compartment pool can be cleaned. Figure 10 The diagram shows the flow of cleaning water.

[0068] like Figures 1 to 15 As shown, the main body 1 of the stormwater storage tank is equipped with a first partition 101 and a second partition 102. The height of the first partition 101 is lower than the height of the second partition 102. A first compartment, a second compartment, and a third compartment are formed between the first partition 101, the second partition 102, and the inner wall of the main body 1 of the stormwater storage tank. The first compartment, the second compartment, and the third compartment are all used to store liquids to achieve rainwater storage and prevent combined sewer overflow pollution.

[0069] The first partition 101 and the second partition 102 are each equipped with a connecting pipe, and a control valve is installed on the connecting pipe. The first compartment pool, the second compartment pool, and the third compartment pool are connected to each other through the connecting pipe. When the control valve is opened, the liquids in the first compartment pool, the second compartment pool, and the third compartment pool will flow to each other to drain the liquids in the first compartment pool, the second compartment pool, and the third compartment pool.

[0070] In addition, the main body 1 of the regulating tank is connected to an inlet pipe 103 and an outlet pipe 104. The inlet pipe 103 is connected to the first compartment and to the upstream pipeline, while the outlet pipe 104 is connected to the third compartment and to the sewage treatment plant pipeline. Liquid in the upstream pipeline can enter the main body 1 of the regulating tank through the inlet pipe 103, and is regulated by the first, second, and third compartments within the main body 1 to avoid combined sewer overflow pollution. If the main body 1 of the regulating tank is full of liquid, it flows to the sewage treatment plant through the outlet pipe 104 to reduce the overload impact on the sewage treatment plant.

[0071] like Figures 1 to 15 As shown, a first filter screen 105 is installed on the top wall of the first partition 101. The first filter screen 105 is used to filter suspended matter in the liquid entering the second compartment from the first compartment.

[0072] Preferably, the height of the first partition 101 and the first filter screen 105 is greater than the height of the second partition 102. When the liquid in the second compartment overflows the second partition 102, the liquid level in the first compartment is still below the first filter screen 105. That is, the first filter screen 105 can still filter the liquid to remove suspended matter from the liquid.

[0073] A second filter screen 106 is connected between the end of the first filter screen 105 and the side wall of the second partition 102, and a third filter screen 107 is connected between the second partition 102 and the inner top wall of the main body 1 of the regulating tank. Both the second filter screen 106 and the third filter screen 107 are used to filter suspended solids in the liquid entering the third compartment from the second compartment, greatly improving the filtration effect of the liquid and reducing the burden on the subsequent sewage treatment plant.

[0074] Preferably, the mesh ratio of the first filter screen 105, the second filter screen 106, and the third filter screen 107 is 1:2:3, which can achieve a progressive filtration effect.

[0075] In another embodiment of this application, the second filter screen 106 may not be provided, that is, only the first filter screen 105 and the third filter screen 107 are used to filter suspended matter in the liquid.

[0076] like Figure 1 As shown, multiple sewage pipes 108 are installed on the side wall of the main body 1 of the regulating tank. The first compartment, the second compartment, and the third compartment are connected to the outside through the sewage pipes 108. When the rainfall stops, the liquid in the first compartment, the second compartment, and the third compartment can be discharged and introduced into the sewage treatment plant to realize the staggered treatment of the liquid in the main body 1 of the regulating tank by the sewage treatment plant, thereby greatly reducing the load on the sewage treatment plant.

[0077] The first compartment pool has a straight pipe 109 installed on its top wall, with multiple nozzles mounted on the pipe. A cleaning pipe is connected to the straight pipe 109 and passes through the main body 1 of the regulating tank. During the initial stages of rainfall, rainwater, contaminants from upstream pipes, and pollutants from the atmosphere and surface will enter the first compartment pool through the inlet pipe 103, resulting in a high level of contaminants within the first compartment pool. Naturally, the bottom of the first compartment pool will also contain a significant amount of contaminants. Therefore, this application only installs the straight pipe 109 within the first compartment pool for cleaning the bottom of the first compartment pool.

[0078] When the bottom of the first compartment needs cleaning, the liquid in the first compartment is drained using the drain pipe 108. The suspended capture mechanism 3 descends to the bottom of the column 2, at which point the capture-type cleaning mechanism 4 can contact the bottom of the first compartment. When the cleaning pipe is connected to a clean water supply, clean water can enter the straight pipe 109 and be sprayed onto the first compartment through the nozzle. Combined with multiple capture-type cleaning mechanisms 4, the bottom of the first compartment can be cleaned, preventing the long-term accumulation of sludge at the bottom from affecting the normal use of the main body of the regulating tank 1. Figure 10 The diagram shows the flow of cleaning water.

[0079] Of course, straight pipes 109 can also be installed in the second and third compartments. Multiple straight pipes 109 can be connected by connecting pipes for cleaning the bottom of the second and third compartments.

[0080] like Figures 1 to 15 As shown, multiple columns 2 are installed in the first compartment pool, and the columns 2 are used to guide the sliding of the suspension capture mechanism 3.

[0081] The column 2 is shorter than the height of the first partition 101 and is used to limit the floating height of the suspension capture mechanism 3. When the liquid in the first compartment pool overflows the first partition 101, some of the liquid in the first compartment pool can enter the suspension capture mechanism 3 and trigger the capture cleaning mechanism 4 to swing irregularly. The irregularly swinging capture cleaning mechanism 4 is used to capture suspended matter in the liquid to remove suspended matter.

[0082] Preferably, the outer side of the column 2 is provided with an anti-corrosion layer to prevent the column 2 from being corroded by liquid and to improve the service life of the column 2.

[0083] In addition, a first support ring 201 is fixedly connected to the side wall of the column 2 to support the suspension plate 301. When there is no liquid in the first compartment pool, the suspension plate 301 contacts the first support ring 201, and the brush bristles 403 can just contact the bottom wall of the first compartment pool so as to use the brush bristles 403 to clean the bottom of the first compartment pool.

[0084] Specifically, a first limiting post 202 is fixedly connected to the top wall of the column 2 to limit the suspension plate 301 and prevent the suspension plate 301 from sliding completely out of the column 2.

[0085] like Figures 1 to 15 As shown, the suspended capture mechanism 3 is located in the first compartment pool and is slidably mounted on multiple columns 2. The suspended capture mechanism 3 is used to install multiple capture-type cleaning mechanisms 4. At the same time, when the main body of the storage tank 1 is used to store rainwater, the suspended capture mechanism 3 can float on the surface of the liquid in the first compartment pool to block large-volume suspended matter.

[0086] The suspension capture mechanism 3 includes a suspension plate 301, on which a pair of buoyancy-enhancing components 302 and a mounting platform 303 are mounted. The pair of buoyancy-enhancing components 302 are symmetrical about the mounting platform 303. Both the suspension plate 301 and the buoyancy-enhancing components 302 are made of materials capable of floating on the liquid surface, such as polystyrene. Through the combined action of the suspension plate 301 and the buoyancy-enhancing components 302, the suspension capture mechanism 3 as a whole can float on the upper side of the liquid, thus effectively blocking large suspended objects. The mounting platform 303 is used to install multiple capture-type cleaning mechanisms 4.

[0087] Preferably, the horizontal cross-sectional area of ​​the suspension plate 301 is smaller than the horizontal cross-sectional area of ​​the first compartment pool. When the suspension capture mechanism 3 floats on the upper side of the liquid in the first compartment pool, the liquid in the first compartment pool can enter the second compartment pool through the gap between the suspension plate 301 and the side wall of the first compartment pool.

[0088] In addition, the mounting platform 303 is embedded with a plurality of evenly distributed oscillating columns 304, which correspond to a plurality of capture-type cleaning mechanisms 4 respectively. The oscillating columns 304 are used to accommodate the oscillating balls 405. At the same time, the oscillating columns 304 are also used to collect clean water so that the clean water can impact the oscillating balls 405, causing the oscillating balls 405 to move irregularly in the conical groove so that the bristles 403 can clean the bottom of the first compartment pool.

[0089] Specifically, a guide pipe 305 is connected to the oscillating column 304. One end of the guide pipe 305 passes through the mounting platform 303 and the suspension plate 301. The liquid in the conical groove and the first compartment pool can be interconnected through the guide pipe 305. At the same time, the clean water in the conical groove can flow to the brush bristles 403 through the guide pipe 305. When the brush bristles 403 clean the bottom of the first compartment pool, the clean water sprayed by the guide pipe 305 can clean the brush bristles 403.

[0090] In addition, both the suspension plate 301 and the mounting platform 303 are provided with interconnected channels 306 for the flow of liquid and clean water in the first compartment pool.

[0091] Furthermore, a pair of guide posts 307 are fixedly connected to the mounting platform 303, and the guide posts 307 are used to guide the sliding of the cover plate 501. The side wall of the guide post 307 is provided with a second support ring, which is used to support the cover plate 501 so that the cover plate 501 can cover the suspension plate 301. The end of the guide post 307 is provided with a second limiting post, which is used to limit the cover plate 501 and prevent the cover plate 501 from sliding completely out of the guide post 307.

[0092] like Figures 1 to 15As shown, multiple capture-type cleaning mechanisms 4 are installed inside the suspension capture mechanism 3. The capture-type cleaning mechanism 4 can swing irregularly under the impact of liquid or clean water in order to capture suspended matter in the liquid. At the same time, when the capture-type cleaning mechanism 4 comes into contact with the bottom of the first compartment pool, it can also clean the dirt at the bottom of the pool.

[0093] The capture-type cleaning mechanism 4 includes a omnidirectional ball 401, and the suspension plate 301 has a rotating groove that matches the omnidirectional ball 401. When the oscillating ball 405 is impacted by liquid, it can move randomly under the action of the omnidirectional ball 401.

[0094] In addition, a mounting column 402 and a connecting column 404 are fixedly connected to the omnidirectional ball 401. One end of the mounting column 402 passes through the suspension plate 301, and multiple bristles 403 are staggered and connected to the side wall of the mounting column 402. The bristles 403 are located on the lower side of the suspension plate 301. When the oscillating ball 405 moves irregularly, the mounting column 402 and the bristles 403 are driven to swing irregularly through the connecting column 404 and the omnidirectional ball 401. The irregularly swinging bristles 403 can capture suspended matter in the liquid. At the same time, when the bristles 403 come into contact with the bottom of the first compartment pool, they can also clean the dirt at the bottom of the first compartment pool.

[0095] Specifically, the surface of the bristles 403 is provided with multiple barbs 4031, which increases the bristles 403's ability to capture suspended matter and improves the bristles 403's ability to clean the sludge at the bottom of the first compartment pool.

[0096] like Figures 5 to 15 As shown, one end of the connecting column 404 is located inside the oscillating column 304, and the end of the connecting column 404 away from the universal ball 401 is connected to the oscillating ball 405. The oscillating column 304 is provided with a conical groove that matches the oscillating ball 405. When liquid or water flows in the conical groove, the liquid or water can impact the oscillating ball 405 and cause the oscillating ball 405 to move randomly.

[0097] The oscillating ball 405 is connected to a floating belt 406, which contains multiple interlayers 4061, each containing multiple activated carbon balls 4062. When the main body of the regulating tank 1 is regulating water flow, liquid enters between the mounting platform 303 and the cover plate 501, impacting the oscillating ball 405 and causing it to move randomly. The floating belt 406 also moves randomly in the liquid, following the oscillating ball 405. The activated carbon balls 4062 within the interlayers 4061 adsorb particulate matter or harmful substances, thereby improving the wastewater treatment capacity of the main body of the regulating tank 1 and reducing the treatment burden on the wastewater treatment plant. Figure 12 The diagram shows a liquid flow.

[0098] like Figures 1 to 15As shown, the auxiliary capture mechanism 5 is installed on the suspension capture mechanism 3 and covers the capture-type cleaning mechanism 4. The auxiliary capture mechanism 5 can also capture suspended objects.

[0099] The auxiliary capture mechanism 5 includes a cover plate 501, which covers the mounting platform 303. When liquid enters between the mounting platform 303 and the cover plate 501, the cover plate 501 can capture suspended matter in the liquid.

[0100] In addition, a telescopic belt 502 is connected to the cover plate 501, and the side wall of the telescopic belt 502 is provided with multiple drainage holes 5021. When the cover plate 501 moves away from the mounting platform 303, the telescopic belt 502 is pulled and stretched, the diameter of the drainage holes 5021 becomes larger, and the liquid between the mounting platform 303 and the cover plate 501 can be discharged through the drainage holes 5021, while larger suspended particles are intercepted by the cover plate 501, thus playing a role in capturing suspended particles.

[0101] Specifically, a fixing ring 503 is connected to the telescopic belt 502. The fixing ring 503 surrounds the mounting platform 303 and is fixedly connected to the suspension plate 301, which is used to fix the cover plate 501 and the telescopic belt 502 to the outside of the mounting platform 303.

[0102] In addition, a pair of connecting ears 504 are connected to the side wall of the cover plate 501. The pair of connecting ears 504 are slidably disposed on a pair of guide posts 307. The connecting ears 504 are disposed between the second support ring and the second limiting post. By sliding the connecting ears 504 on the guide posts 307, the smooth sliding effect of the cover plate 501 can be ensured.

[0103] Furthermore, the top wall of the cover plate 501 is provided with multiple through holes 505, and the liquid between the mounting platform 303 and the cover plate 501 can also be discharged through the through holes 505 to ensure the rainwater storage effect. At the same time, when cleaning the bottom of the first compartment pool, the cleaning water can enter between the mounting platform 303 and the cover plate 501 through the through holes 505 and enter the oscillating column 304 to impact the oscillating ball 405, causing the oscillating ball 405 to swing irregularly.

[0104] Preferably, the through hole 505 is a horn hole, and the diameter of the channel 306 is larger than the minimum diameter of the drain hole 5021 and the through hole 505, so that the liquid suspension entering between the mounting platform 303 and the cover plate 501 can be intercepted by the cover plate 501 and the telescopic belt 502.

[0105] A method for using an overflow sewage storage device includes the following steps:

[0106] S1. During rainfall, initial rainwater, sewage from upstream pipes, and pollutants from the atmosphere and the ground enter the first compartment pool through the inlet pipe 103.

[0107] S2. If it continues to rain outside, the water level in the first compartment will gradually increase, and the suspension plate 301 will float up along the column 2 and always float on the top of the liquid.

[0108] S3. When the suspension plate 301 moves to the end of the column 2, the suspension plate 301 stops rising. Some of the liquid in the first compartment pool will enter between the mounting platform 303 and the cover plate 501 through the channel 306. The cover plate 501 is impacted by the liquid and moves away from the mounting platform 303. At this time, the telescopic belt 502 is pulled and stretched, and the diameter of the drain hole 5021 becomes larger. The liquid between the mounting platform 303 and the cover plate 501 will be discharged through the drain hole 5021 and the through hole 505 respectively.

[0109] S4. Some of the liquid in the first compartment pool will also enter the conical groove through the guide pipe 305 and impact the oscillating ball 405. Under the action of the connecting column 404 and the universal ball 401, the oscillating ball 405 moves randomly in the conical groove. The randomly moving oscillating ball 405 drives the mounting column 402 and the bristles 403 to swing randomly under the suspension plate 301, and drives the floating belt 406 to swing randomly between the mounting platform 303 and the cover plate 501. Figure 12 The schematic diagram of liquid flow shown shows that the irregularly swaying bristles 403 can capture suspended matter and pollutants in the liquid below the suspension plate 301, and the activated carbon balls 4062 in the irregularly swaying floating belt 406 can adsorb smaller particles and harmful substances between the mounting platform 303 and the cover plate 501. At the same time, since the suspension plate 301 floats on the upper side of the first compartment pool, the suspension plate 301 can also block large suspended matter in the liquid.

[0110] S5. When the liquid level in the first compartment tank exceeds the first partition 101, the liquid enters the second compartment tank through the first filter screen 105, and the first filter screen 105 is used to further filter the suspended matter in the liquid.

[0111] S6. When the liquid level in the second compartment exceeds the second baffle 102, the liquid enters the third compartment through the third filter 107. The second filter 106 and the third filter 107 can continue to filter the suspended solids in the liquid. Finally, the liquid in the third compartment enters the sewage treatment plant through the drain pipe 104. The first, second and third compartments in the main body of the regulating tank 1 are used for rainwater regulation to avoid combined sewer overflow pollution.

[0112] S7. If the rainfall stops, the liquid in the first, second and third compartments will be discharged through the sewage pipe 108 and introduced into the sewage treatment plant through the sewage pipe 108, so as to realize the staggered treatment of the liquid in the main body of the regulating tank 1 by the sewage treatment plant, thereby greatly reducing the load on the sewage treatment plant.

[0113] S8. When it is necessary to clean the bottom of the first compartment pool, the liquid in the first compartment pool is drained using the drain pipe 108. The suspension capture mechanism 3 will descend to the bottom of the column 2. At this time, the capture cleaning mechanism 4 can contact the bottom of the first compartment pool. The cleaning pipe is connected to the clean water supply end. The clean water is sprayed onto the first compartment pool through the nozzle on the straight pipe 109. Some of the clean water sprayed by the nozzle will fall directly to the bottom of the first compartment pool, and some of the clean water will enter between the mounting platform 303 and the cover plate 501 through the through hole 505.

[0114] S9. Some of the clean water between the mounting platform 303 and the cover plate 501 is discharged directly to the bottom of the first compartment pool through the channel 306. Some of the clean water enters the conical groove and impacts the vibrating ball 405, thereby causing the mounting column 402 and the brush bristles 403 to swing irregularly. Figure 10 The diagram showing the flow of cleaning water indicates that the irregularly swaying bristles 403 can clean the dirt at the bottom of the first compartment pool, and the clean water in the conical groove flows to the bristles 403 through the guide pipe 305 to clean the bristles 403.

[0115] S10. After the bottom of the first compartment is cleaned, the sludge and sewage can be discharged through the sewage pipe 108 and introduced into the sewage treatment plant.
