Description

Technical Field

[0001] The invention belongs to the technical field of regulating and storage tanks, and in particular relates to an integrated interception and purification regulating and storage tank. Background Art

[0002] In the construction of sponge cities and the treatment of black and odorous water bodies, regulating and storage ponds are an important component. They can avoid rainwater peaks, reduce the pressure on drainage pipe networks, and prevent urban waterlogging; control non-point source pollution, protect receiving water bodies, and avoid direct discharge of sewage; for combined sewer systems, regulating and storage ponds can store combined sewage that exceeds the design scale of the sewage treatment plant and cannot be accepted, thereby reducing the operating load of the sewage treatment plant; the rainwater stored during the rainfall period is purified through sedimentation, infiltration or filtration to meet different usage needs and realize rainwater recycling.

[0003] Due to issues such as land availability and construction impacts, this sector often resorts to large-scale wastewater storage at the end of the pipe network. This results in a high volume of wastewater mixed with external water (such as rainwater, groundwater, and mountain springs), resulting in a situation where pollutant concentrations are low. The industry consensus is to move from end-of-pipeline storage to source-based storage, i.e., storage at residential exits and roads. This requires integrated storage tanks with high integration and rapid construction. However, the market currently lacks mature, integrated storage tanks that can meet multiple storage functions.

DETAILED DESCRIPTION

[0028] This embodiment provides an integrated interception purification storage tank, such as Figure 1-Figure 5 As shown, it includes an interception area 1, a storage area 2 and a purification area 3 connected in sequence, the interception area 1 includes a water inlet pipe 4, a sewage outlet pipe 5 and a rainwater outlet pipe 6, the interception area 1 is connected to the front end of the storage area 2 through a water inlet 7 and a water outlet 8, so that the water in the interception area 1 can be input into the storage area 2 and returned from the storage area 2 to the interception area 1; the sewage outlet pipe 5, the water inlet 7 and the water outlet 8 are all provided with a flexible intercepting device for controlling the opening and closing of the sewage outlet pipe 5, the water inlet 7 and the water outlet 8 according to the water quality in the interception area 1;

[0029] The rear end of the storage area 2 is connected to the purification area 3 through a first submersible sewage pump 9. The purification area 3 includes a purification device 11 and a second submersible sewage pump 10 arranged in sequence. The purification device 11 is used to purify the water in the purification area 3. The outlet of the second submersible sewage pump 10 is connected to a recovery pipe 12 for outputting the purified water.

[0030] Optionally, a water inlet pipe 4 and a rainwater outlet pipe 6 are provided on both sides of the interception area 1, a sewage outlet pipe 5 is provided at the front end of the interception area 1, and a water inlet 7 and a water outlet 8 are provided at the rear end. The outlet end of the water inlet pipe 4 is provided with a grid 13 for intercepting solid pollutants in the influent water;

[0031] The water inlet end of the sewage outlet pipe 5 is provided with a first flexible intercepting device 14, the water inlet 7 is provided with a second flexible intercepting device 15, the water outlet 8 is provided with a third flexible intercepting device 16, and the rainwater outlet pipe 6 is provided with a control valve;

[0032] A first liquid level meter, a first gas detector and a first water quality detector are provided in the interception area 1 for real-time monitoring of the water quality in the interception area 1 .

[0033] Sewage and / or rainwater are input into the interception area 1 through the water inlet pipe 4, and after filtering the solid pollutants, they are temporarily stored in the interception area 1. At the initial stage of rainfall, the initial rainwater with high pollutant concentration is discharged into the sewage treatment network through the sewage outlet pipe 5, waiting to be sent to the sewage treatment plant for treatment; in the middle and late stages of rainfall, when the pollution concentration is low as detected by the above-mentioned liquid level meter and detector, the first flexible intercepting device 14 is closed and the second flexible intercepting device 15 is opened, and the rainwater with low pollutant concentration enters the regulating and storing area 2 for storage; during continuous rainfall, when the water storage capacity of the regulating and storing area 2 reaches the set value (that is, close to the total water storage capacity of the regulating and storing area 2), the second flexible intercepting device 15 is closed, and the rainwater with lower pollutant concentration in the later stage is directly discharged into the natural water body through the rainwater outlet pipe 6.

[0034] When the stored water in the regulating and storage area 2 needs to be recycled, the water in the regulating and storage area 2 is discharged into the purification area 3 through the first submersible sewage pump 9, and is processed by the purification device 11 to obtain recycled water. The water is then output by the second submersible sewage pump 10 through the recovery pipe 12 to the equipment or pipeline that needs the recycled water.

[0035] When the rainy season is low and the water inlet pipe 4 is not flowing, the third flexible intercepting device 16 is opened, and the water in the regulating and storing area 2 can return to the intercepting area 1 through the outlet 8. After the water quality is tested, the water is discharged from the sewage outlet pipe 5 or the rainwater outlet pipe 6, freeing up space in the regulating and storing area 2 and waiting for the next regulation and storage use.

[0036] For source regulation, that is, regulation in locations such as residential areas and roads, the amount of water stored is not large, but rapid turnover is required to promptly empty the storage area 2 so that the next collection of stored water can be done. The present invention uses the interception area 1, the storage area 2, and the purification area 3 in series, which not only adds the functions of interception and purification to the storage pool, but also, when the water inlet pipe 4 is not flowing with water, the interception area 1 can be used in conjunction with the storage area 2, increasing the volume that can accommodate the stored water and improving the storage capacity. The water in the storage area 2 can also be quickly processed by the interception area 1, so that the storage area 2 can be emptied and ready to receive rainwater or sewage next time.

[0037] Further optionally, a first inspection well 17 is provided on the top of the interception area 1 to facilitate inspection and maintenance of the interception area 1.

[0038] Optionally, the first flexible intercepting device 14 includes a circular inflatable base and a plurality of inflatable petals 21, wherein the circular inflatable base includes a circular inflatable bag 20 and skirts on both sides of the inflatable bag 20, the outer side of the inflatable bag 20 is in close contact with the inner wall of the water inlet end of the sewage outlet pipe, and the skirts on both sides of the inflatable bag 20 are fixed to the inner wall of the water inlet end of the sewage outlet pipe by bolts to fix the inflatable bag 20;

[0039] The inflatable flaps 21 are fan-shaped when inflated, and a plurality of inflatable flaps 21 are evenly distributed along the circumference of the inner side of the inflatable bag 20, so that the inflated inflatable flaps 21 form a circle, blocking the circular cross-section of the inflatable bag 20, thereby blocking the water inlet end of the sewage outlet pipe 5.

[0040] Further optionally, the outer side of the inflatable bag 20 is provided with a plurality of inflation and exhaust ports, each of which corresponds to an inflation flap 21. The inflation and exhaust ports can not only evenly inflate the inflatable bag 20 so that the inflatable bag 20 quickly expands to become an annular base, but also inflate the corresponding inflation flap 21 so that the inflation flap 21 quickly expands to block the sewage outlet pipe 5, and exhaust is also carried out through the inflation and exhaust ports.

[0041] Further optionally, a plurality of positioning guide rods 22 are provided at the water inlet end of the sewage outlet pipe 5 and on the upstream side of the first flexible intercepting device 14, each positioning guide rod 22 corresponding to the position of the gap between two adjacent inflatable petals 21, and the root of the positioning guide rod 22 is rotatably connected to the side wall of the pipe opening at the water inlet end of the sewage outlet pipe, and the plurality of positioning guide rods 22 are radially arranged along the radial direction of the circular cross-section of the sewage outlet pipe 5;

[0042] The positioning guide rod 22 is hollow, and a gap parallel to the positioning guide rod 22 is provided on the side facing the inflatable valve 21. The gap is a slide 23, and a slider 24 is clamped in the slide 23. The slider 24 can slide along the slide 23; a flushing pipe 25 is inserted into the interior of the positioning guide rod 22, and the outlet of the flushing pipe 25 is clamped on the slider 24 and extends out of the positioning guide rod 22. An infrared sensor is provided at the outlet of the flushing pipe 25.

[0043] The root of the positioning guide rod 22 is rotatably connected to the side wall of the water inlet end of the sewage outlet pipe, so that the positioning guide rod 22 is free to rotate with the root as a fulcrum. The inlet of the flushing pipe 25 can be connected to the regulating storage area 2 or the purification area 3 or the recovery pipe 12 or other water supply device, and the water supply pipe can be used for water supply.

[0044] Further optionally, the inflation and exhaust ports are connected to branch air paths, and each branch air path is provided with a regulating valve for adjusting the inflation volume and inflation speed of each inflation and exhaust port; several branch air paths are connected in parallel to a main air path, and the main air path is connected to the inflation and exhaust device, and the inflation and exhaust device can be set outside the interception area 1, where it is easy to operate.

[0045] When it is necessary to discharge the highly polluted sewage in the interception area 1 into the sewage outlet pipe 5, the first flexible intercepting device 14 is originally in an inflated and sealed state. The inflatable bag 20 and the inflatable flap 21 are vented through the inflation and exhaust device and the inflation and exhaust port. At the same time, the positioning guide rod 22 rotates away from the pipe mouth position, which will not hinder drainage. As the first flexible intercepting device 14 gradually exhausts, the pipe mouth at the water inlet end of the sewage outlet pipe gradually becomes exposed and expanded, and the sewage in the interception area 1 can be discharged from the sewage outlet pipe 5. The first flexible intercepting device 14 can gradually relax the pipe mouth during the exhaust process, so that the water output of the sewage outlet pipe 5 experiences a process from small to large, providing a buffer for the equipment or devices downstream of the sewage outlet pipe 5.

[0046] When there is no need to drain water to the sewage outlet pipe 5, the inflatable bag 20 and the inflatable flap 21 are inflated through the inflation and exhaust device and the inflation and exhaust port. Since the first flexible intercepting device 14 has been flushed by sewage, solids will remain in its gaps, especially the solid particles in the gaps between the inflatable flaps 21. During the subsequent inflation process, they will be squeezed between the two inflatable flaps 21, and there is a high possibility of puncturing the inflatable flap 21, causing the inflatable flap 21 to suddenly burst. This danger is more likely to occur when the amount of inflation of the inflatable flap 21 is greater.

[0047] To address this issue, the present invention provides positioning guide rods 22 corresponding to adjacent inflation flaps 21 and flushing pipes 25 therein. When inflation begins, the positioning guide rods 22 rotate toward the pipe opening. At this point, there may be water flowing toward the pipe opening. The process of the positioning guide rods 22 rotating around the pipe opening and toward the pipe opening can be aided by the water flow. Alternatively, the water inlet end of the sewage outlet pipe 5 may be submerged, in which case the positioning guide rods 22 rotate without resistance. In short, the positioning guide rods 22 move to the sewage outlet pipe opening and are located radially in the circular cross-section of the sewage outlet pipe opening.

[0048] The slider 24 and the outlet of the flush pipe 25 are located at the root of the positioning guide rod 22. As inflation proceeds, the inflatable bag 20 is first filled, and the slider 24 moves along the slide 23 toward the other end of the positioning guide rod 22. Then, the inflatable flaps 21 gradually inflate from their root to their tip, and the gaps between adjacent inflatable flaps 21 are gradually squeezed in this direction. During this process, the slider 24 continues to move along the slide 23 toward the center of the circular cross-section of the pipe opening. At the same time, water flows through the flush pipe 25, continuously spraying water into the gaps between adjacent inflatable flaps 21 through the outlet of the flush pipe 25, creating additional water flow impact, flushing solid waste in the gaps between adjacent inflatable flaps 21 into the sewage outlet pipe 5, ensuring that the inflatable flaps 21 close smoothly after inflation and block the pipe opening. The flush pipe 25 can penetrate the positioning guide rod 22 from the root of the positioning guide rod 22, or from the free end of the positioning guide rod 22.

[0049] Then, the flush pipe 25 stops spraying water, the infrared sensor starts, and moves back and forth with the slider 24 to patrol and detect whether the gaps of adjacent inflatable flaps 21 remain effectively blocked. When the light of the infrared sensor can pass through the gaps of the inflatable flaps 21, it means that the inflatable flap 21 is not tightly sealed due to air leakage, and there may be water leakage, guiding the staff to carry out timely maintenance.

[0050] The second flexible intercepting device 15 and the third flexible intercepting device 16 have the same structure as the first flexible intercepting device 14, and the operation and working principles are the same as those of the first flexible intercepting device 14. The positioning guide rod 22 of the second flexible intercepting device 15 is arranged on the upstream side of the water inlet 7, that is, on the side close to the intercepting area 1; the positioning guide rod 22 of the third flexible intercepting device 16 is arranged on the upstream side of the water outlet 8, that is, on the side close to the storage area 2.

[0051] Optionally, a first water storage tank 26 is provided at the bottom of the rear end of the regulating and storing area 2, and a first submersible sewage pump 9 is installed in the first water storage tank 26.

[0052] The outlet of the first submersible sewage pump 9 passes through the rear end side wall of the regulating and storing area 2 and enters the purification area 3 , and is used to input the water in the regulating and storing area 2 into the purification area 3 .

[0053] Further optionally, the bottom surface of the first water storage tank 26 is the lowest point of the bottom surface of the regulating and storing area 2, so that the water in the regulating and storing area 2 can naturally flow into the first water storage tank 26 when discharged into the purification area 3, thereby facilitating the discharge of the clean water in the regulating and storing area 2.

[0054] Further optionally, a check valve is provided at the outlet of the first submersible sewage pump 9 to prevent the water in the purification area 3 from flowing back into the first water storage tank 26 .

[0055] Further optionally, a second inspection well 18 and several ventilation pipes 29 are provided on the top of the regulating and storage area 2. The regulating and storage area 2 is horizontal, and the several ventilation pipes 29 are evenly arranged along the length direction of the regulating and storage area 2 to discharge the waste gas generated during the long-term storage of water in the regulating and storage area 2; the second inspection well 18 is provided at the rear end of the regulating and storage area 2 to facilitate the inspection and maintenance of the regulating and storage area 2.

[0056] Optionally, the purification area 3 includes a purification device 11, an overflow weir 30, and a second water storage tank 27 arranged in sequence. The overflow weir 30 is provided on the downstream side of the purification device 11. The two sides of the overflow weir 30 are respectively connected to two opposite side walls of the purification area 3, dividing the purification area 3 into two parts, the front and the back. The height of the overflow weir 30 is higher than the height of the purification device 11. The water purified by the purification device 11 overflows through the overflow weir 30 and flows into the second water storage tank 27.

[0057] The second water storage tank 27 is arranged at the bottom of the rear end of the purification area 3. The second submersible sewage pump 10 is installed in the second water storage tank 27. The recovery pipe 12 is vertically arranged and passes through the top surface of the purification area 3 for connecting other equipment or pipes that need to use recycled water.

[0058] Further optionally, the purification device 11 is a purification layer filled with filter material, and the purification layer covers all cross sections from the upstream side wall of the purification zone 3 to the overflow weir 30, so that the influent of the purification zone 3 can all pass through the purification layer;

[0059] Support grids are installed above and below the purification layer to support and restrain the filter material, which is the concave polyhedron streamlined suspended lightweight filter material disclosed in Patent 202210165396.X.

[0060] Further optionally, the second water storage tank 27 is the lowest point of the rear part, and a second liquid level meter, a second gas detector and a second water quality detector are provided in the second water storage tank 27 for real-time monitoring of the water quality in the second water storage tank 27. After the water quality is qualified, it is discharged by the second submersible sewage pump 10 and the recovery pipe 12.

[0061] The first submersible sewage pump 9 inputs the water from the storage area 2 into the purification area 3. Due to the blocking effect of the overflow weir 30, the water accumulates in the front part of the purification area 3 and continuously passes through the purification device 11 from bottom to top. After purification, it overflows from the overflow weir 30 to the rear part of the purification area 3 and accumulates in the second water storage tank 27, waiting for the second submersible sewage pump 10 to output the water.

[0062] Further optionally, a third water storage tank 28 is provided at the bottom of the purification area 3 corresponding to the position of the purification device 11. The third water storage tank 28 is the lowest point of the front part. A third liquid level gauge and a drain pipe are provided in the third water storage tank 28. The drain pipe is connected to the sewage treatment network or sewage treatment plant.

[0063] A cleaning water inlet is provided at the top of the front end of the purification zone 3 , and the cleaning water inlet is connected to the recovery pipe 12 , and the purified recycled water is used as cleaning water to clean the purification device 11 .

[0064] When the purification device 11 needs to be cleaned, the water in the front part is discharged through the drain pipe. Due to the blocking effect of the overflow weir 30, the water in the rear part will not flow back to the front part. The recycled water enters the front part from the cleaning water inlet and reversely flushes the purification device 11 from top to bottom. The cleaned water falls into the third water storage tank 28. When the liquid level of the third water storage tank 28 is too high, the water in the third water storage tank 28 is discharged to the outside through the drain pipe, for example, to the sewage treatment network or sewage treatment plant.

[0065] Further optionally, a third inspection well 19 is provided on the top of the purification area 3 to facilitate inspection and maintenance of the purification area 3.

[0066] Further optionally, vertical ladders 31 are provided in the purification area 3 and the interception area 1 to facilitate entry and exit of staff.

[0068] The controller is also communicatively connected to the filling and exhaust devices of all flexible intercepting devices, the regulating valves of the gas path, the positioning guide rod 22 and the slider 24, the infrared sensor and the flushing pipe 25. When the sewage outlet pipe 5, the rainwater outlet pipe 6, the water inlet 7 and the water outlet 8 need to be opened or closed, the controller controls the corresponding flexible intercepting device to operate in the same manner as the first flexible intercepting device 14 described above.

[0069] The operating parameters of the equipment used are displayed on the monitor for management by the staff. When there is leakage in the flexible shut-off device or other equipment operating failure, the alarm will sound.
