Description

Technical Field

[0001] This application relates to the field of rainwater harvesting and treatment technology, and in particular to an integrated rainwater utilization device. Background Technology

[0002] The construction of a rainwater harvesting system in the park can effectively recycle and utilize natural precipitation, significantly reducing reliance on municipal tap water for greening irrigation, road cleaning, and landscape water replenishment, thus saving water resources and operating costs. Simultaneously, it can effectively collect and regulate rainwater during the rainy season, alleviating waterlogging in the park and reducing pressure on urban drainage networks, thereby lowering the risk of urban flooding. Furthermore, it can reduce runoff pollution through purification treatment, conserve groundwater resources, improve the park's ecological environment, and contribute to creating a green, low-carbon, and water-saving park.

[0003] The park's rainwater collection system primarily gathers rainwater from paved surfaces such as rooftops, roads, and plazas. After initial rainwater with more impurities is removed by a diversion device, it is transported through a dedicated pipeline network to sedimentation tanks and filtration devices for preliminary purification. The treated rainwater is then stored in a reservoir, undergoes further simple filtration or disinfection, and is then pumped to water usage points for landscaping, cleaning, and other purposes. Some areas can be integrated with sunken green spaces, permeable paving, and other ecological facilities to combine rainwater infiltration, retention, and collection for reuse.

[0004] Most existing rainwater harvesting systems first transport rainwater to the collection unit via external pipe networks, and then transport it to different treatment units through various conveying mechanisms for collection and utilization. However, in actual operation, the dispersed layout of equipment in each treatment stage often occupies a lot of space, and the long conveying paths increase energy consumption and the risk of blockages, reducing the efficiency of rainwater collection and utilization and hindering the achievement of efficient and intensive treatment. In addition, existing rainwater harvesting systems often fail to deeply integrate with the park's fire protection system, resulting in significant duplication of investment in municipal fire protection pipe networks and water storage facilities, increasing the burden on urban infrastructure construction, and making it difficult to fully meet the macro-planning requirements of "sponge city" construction regarding on-site water resource utilization and low-carbon reuse. Summary of the Invention

[0006] The purpose of this application is to address the problem in the above-mentioned background technology that, in actual operation, the various processing links often occupy a lot of space due to the dispersed arrangement of equipment, and the long transportation path easily increases energy consumption and the risk of blockage, which reduces the efficiency of rainwater collection and utilization and is not conducive to achieving efficient and intensive treatment. This application provides a rainwater integrated utilization device.

[0007] To achieve the above objectives, this application specifically adopts the following technical solution:

[0008] A rainwater integrated utilization device includes a collection tank. A delivery pipe is fixedly connected to one side of the collection tank, and a centrifugal filter is fixedly connected to one end of the delivery pipe. A water supply pipe is fixedly connected to the middle of one side of the centrifugal filter, and a return pipe is fixedly connected to the bottom of the centrifugal filter. One end of the return pipe is connected to the collection tank. A sedimentation tank is provided on one side of the collection tank. The spray end of the water supply pipe is located at the bottom inner side of the sedimentation tank. An emptying pump is provided on one side of the sedimentation tank, and a lift pump is provided on the other side of the sedimentation tank. The discharge end of the emptying pump is connected to the collection tank, and one end of the lift pump is connected to a fine filter. A drain pipe is connected to one side of the bottom of the fine filter, and one end of the drain pipe is connected to a fire pool. A first delivery pump is installed inside the fire pool, and a second delivery pump is installed on one side of the fire pool. One end of the second delivery pump is connected to a disinfection tank, and a drain pipe is fixedly connected to one side of the disinfection tank. An elastic mounting frame is installed inside the fine filter, and a detachable fine filter element is installed on the elastic mounting frame. A swinging element is installed on one side of the fine filter, and a driving element is installed on one side of the fine filter. The actuating end of the driving element corresponds to the swinging element. An agitator is installed at the bottom of the fine filter, and the driving element is connected to the agitator in a transmission manner.

[0009] By adopting the above technical solution, when collecting rainwater, the park's rainwater pipe network is connected to the collection pool. The rainwater undergoes preliminary filtration through a centrifugal filter, then enters a sedimentation tank for further sedimentation and filtration, followed by a fine filter for further filtration. After fine filtration, the rainwater is collected in a fire-fighting pool. Part of the rainwater is used for fire-fighting reserves, while another part is pumped and lifted by a transfer pump. The rainwater then enters a disinfection tank for disinfection, and is subsequently lifted to rooftop water tanks on the roofs of external buildings for domestic use, as well as for landscaping and car washing. This integrated collection and utilization of rainwater maximizes the efficiency of rainwater collection and treatment.

[0010] Furthermore, the collection pool has a diversion well chamber and a collection well chamber on its two sides respectively. A butterfly valve is installed between the diversion well chamber and the collection well chamber. An overflow ditch is connected to one side of the diversion well chamber and the collection well chamber. A sewage pipe is connected to one side of the diversion well chamber, and a collection pipe is connected to the top of one side of the collection well chamber.

[0011] By adopting the above technical solution, rainwater from the external municipal pipe network is transported to the collection well chamber through the collection pipe to replenish the water source. At the beginning of the rainfall, the butterfly valve is in the connected state, allowing the rainwater to flow into the diversion well chamber and be discharged through the sewage pipe. At the middle of the rainfall, the butterfly valve is closed. As the water level in the collection well chamber rises, the rainwater can be transported to the centrifugal filter through the delivery pipe for filtration.

[0012] Furthermore, a partition is fixedly connected in the middle of the interior of the sedimentation tank, and a filter screen is provided at the bottom of the partition. The partition divides the interior of the sedimentation tank into a sedimentation chamber and a clear water chamber. The drain pump is installed inside the sedimentation chamber, and the lift pump is installed inside the clear water chamber.

[0013] By adopting the above technical solution, when the water supply pipe delivers the filtered rainwater to the sedimentation tank, the rainwater can enter the sedimentation chamber for settling. During this period, the rainwater passes through the filter screen and enters the clear water chamber, where it is further filtered by the filter screen.

[0014] Furthermore, the fine filter has a fine filtration chamber inside and an adsorption chamber at the bottom. The elastic mounting frame and the fine filter element are both installed inside the fine filtration chamber, and a sand filter screen box is placed on top of the elastic mounting frame. The adsorption chamber is filled with activated carbon particles. A water pump is fixedly connected to one side of the bottom of the fine filter, and a protective mesh box is fixedly connected to the pump's extraction end.

[0015] By adopting the above technical solution, when rainwater enters the fine filter, it can first enter the sand filter box, where the sand particles inside the sand filter box intercept and filter the impurities in the rainwater.

[0016] Furthermore, the bottom of the elastic mounting bracket is provided with a sliding groove, and a sliding seat is slidably connected inside the sliding groove. Both ends of the sliding groove are fixedly connected with a spring telescopic rod, and the bottom of the sliding seat is installed and connected to the fine filter element.

[0017] By adopting the above technical solution, when the swinging component moves the fine filter element, it can drive the slide to slide inside the slide groove. During this period, the slide is reset by the elastic action of the spring telescopic rod, thus realizing the reciprocating swaying of the fine filter element.

[0018] Furthermore, the fine filter element includes a connecting plate installed at the bottom of the slide, and a plurality of fine filter membrane tubes are fixedly connected to the bottom of the connecting plate. A sealing plate is fixedly connected to the bottom end of the fine filter membrane tube, and the sealing plate is connected to the top end of the adsorption chamber.

[0019] By adopting the above technical solution, rainwater can be filtered by infiltrating into the fine filtration membrane tube, and the filtered rainwater can enter the adsorption chamber along the diameter of the fine filtration membrane tube to achieve fine filtration of rainwater.

[0020] Furthermore, the swinging component includes a slide rail fixedly connected to the inner wall of the fine filtration chamber, a slider slidably connected inside the slide rail, a U-shaped lever fixedly connected to one side of the slider, two spring telescopic rods fixedly connected to both sides of the slider, and a lever fixedly connected to the bottom of the slider.

[0021] By adopting the above technical solution, the internal components of the driving component can intermittently drive the dial block through the operation of the driving component, so that the dial block drives the slider to slide inside the slide rail. During this period, the slider is reset by the elastic action of the spring telescopic rod II, which can drive the U-shaped dial to reciprocate toggle the connecting plate.

[0022] Furthermore, the driving component includes a connecting sleeve plate fixedly connected to the inner wall of the fine filter chamber, a driving disk rotatably connected to the inner top end of the connecting sleeve plate, a servo motor fixedly connected to one side of the fine filter, a rotating shaft fixedly connected to the output end of the servo motor, the rotating shaft being fixedly connected to the driving disk, and a dial plate fixedly connected to one side of the driving disk, the dial plate corresponding to a dial block.

[0023] By adopting the above technical solution, the operation of the servo motor can drive the rotating shaft to rotate, and the rotating shaft can drive the drive disk to rotate, thereby driving the dial plate to rotate, so that the dial plate can intermittently drive the dial block.

[0024] Furthermore, the agitator includes a driven disc rotatably connected to the bottom of the connecting sleeve plate, a turntable fixedly connected to one side of the driven disc, and a plurality of agitating rods fixedly connected to one side of the turntable. The driven disc and the driving disc are connected by a transmission belt.

[0025] By adopting the above technical solution, when the drive disc rotates, the driven disc can be driven to rotate via the transmission belt. The rotating driven disc can drive the turntable to rotate, which in turn drives the stirring rod to rotate, thereby loosening and mixing the activated carbon particles inside the adsorption chamber.

[0026] In summary, this application includes at least one of the following beneficial effects;

[0027] In this application, when collecting rainwater, the park's rainwater pipe network is connected to the collection pool. The rainwater undergoes preliminary filtration through a centrifugal filter, followed by sedimentation and filtration in a sedimentation tank, and then further filtration in a fine filter. After fine filtration, it is collected in a fire-fighting pool, where a portion of the rainwater is used for fire-fighting reserves. Prioritizing the use of deeply purified rainwater for fire-fighting reserves not only meets the park's internal fire emergency needs but also significantly reduces reliance on municipal tap water as a fire-fighting water source, thereby lowering the initial investment in municipal fire-fighting pipe network laying and water supply facilities. This model alleviates the pressure on the city's public pipe network for water supply and drainage, giving government departments greater flexibility in the overall planning of urban water resources and infrastructure. Simultaneously, another portion of the rainwater is pumped and lifted by a second pump, entering a disinfection tank for disinfection. The rainwater is then lifted to rooftop water tanks on external buildings for domestic use, as well as for landscaping and car washing, thus achieving integrated rainwater collection and utilization and maximizing the efficiency of rainwater collection and treatment. This intensive and efficient rainwater resource utilization model truly aligns with the "sponge city" construction concept of infiltration, retention, storage, purification, utilization, and drainage, effectively reducing carbon emissions from long-distance water diversion and helping to achieve the goals of green and low-carbon urban development planning.

[0028] 2. In this application, when rainwater enters the fine filter, it passes through the fine filter element under water pressure, thus performing fine filtration. During the fine filtration, the internal components of the driving component rotate, which in turn drives the oscillating component. This causes the internal components of the oscillating component to reciprocate and push against the upper end of the fine filter element, thereby driving the fine filter element to reciprocate. This causes one end of the fine filter element to sway on the elastic mounting bracket, which in turn causes the fine filter element to shake back and forth, thus shaking off impurities adhering to the fine filter element, maintaining smooth filtration, maximizing filtration efficiency and water quality stability, and ensuring the reliability of subsequent rainwater recycling.

[0029] 3. In this application, when the internal components of the driving component are running, the internal components can simultaneously drive the agitator, so that the internal components of the agitator can run and agitate the activated carbon particles inside the adsorption chamber, thereby loosening and mixing the activated carbon particles, improving the adsorption and purification effect, maximizing the removal effect of impurities in rainwater, realizing multi-stage filtration and efficient utilization of rainwater, and thus improving the reliability of rainwater recycling.

[0041] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0042] This application discloses an integrated rainwater utilization device.

[0043] Reference Figures 1 to 6A rainwater integrated utilization device includes a collection tank 3. A conveying pipe 11 is fixedly connected to one side of the collection tank 3. A centrifugal filter 2 is fixedly connected to one end of the conveying pipe 11. A water supply pipe 13 is fixedly connected to the middle of one side of the centrifugal filter 2, and a return pipe 12 is fixedly connected to the bottom of the centrifugal filter 2. One end of the return pipe 12 is connected to the collection tank 3. A sedimentation tank 1 is provided on one side of the collection tank 3. The spray end of the water supply pipe 13 is located at the bottom inner side of the sedimentation tank 1. An emptying pump 14 is provided on one side inside the sedimentation tank 1, and a lift pump 15 is provided on the other side inside the sedimentation tank 1. The drain end is connected to the collection tank 3. One end of the lift pump 15 is connected to the fine filter 4. One side of the bottom of the fine filter 4 is connected to the drain pipe 16. One end of the drain pipe 16 is connected to the fire pool 5. The fire pool 5 is equipped with a first transfer pump 51, and a second transfer pump 52 is installed on one side of the fire pool 5. One end of the second transfer pump 52 is connected to the disinfection tank 6. One side of the disinfection tank 6 is fixedly connected to the drain pipe 61. The fine filter 4 is equipped with a flexible mounting bracket 44. A detachable fine filter element 10 is installed on the flexible mounting bracket 44. A swinging element 7 is installed on one side of the fine filter 4. A drive component 8 is installed, with its actuating end corresponding to the oscillating component 7. A stirring component 9 is installed at the bottom of the fine filter 4. The drive component 8 and the stirring component 9 are connected in a transmission manner. A diversion well chamber 31 and a collection well chamber 32 are respectively opened on both sides of the inside of the collection tank 3. A butterfly valve 33 is installed between the diversion well chamber 31 and the collection well chamber 32. An overflow ditch 34 is connected to one side of the diversion well chamber 31 and the collection well chamber 32. A sewage pipe 35 is connected to one side of the diversion well chamber 31. A collection pipe 36 is connected to the top of one side of the collection well chamber 32. A partition 17 is fixedly connected in the middle of the inside of the sedimentation tank 1. A bottom end of the partition 17 is provided with The sedimentation tank 1 is divided into a sedimentation chamber and a clear water chamber by a partition 17. An emptying pump 14 is installed inside the sedimentation chamber, and a lifting pump 15 is installed inside the clear water chamber. The fine filter 4 is provided with a fine filtration chamber 41 and an adsorption chamber 42 at the bottom. The elastic mounting frame 44 and the fine filter element 10 are both installed inside the fine filtration chamber 41. A sand filter box 43 is placed on the top of the elastic mounting frame 44. The adsorption chamber 42 is filled with activated carbon particles. A water pump 45 is fixedly connected to one side of the bottom of the fine filter 4. A protective net box 46 is fixedly connected to the extraction end of the water pump 45.

[0044] The rainwater collection system utilizes a collection tank 3, which is divided into a diversion chamber 31 and a collection chamber 32. The connection between the two is controlled by a butterfly valve 33, and both sides are connected to overflow channels 34. A sewage pipe 35 is installed on one side of the diversion chamber 31, and a collection pipe 36 is connected to the top of the collection chamber 32. During operation, the external municipal water supply network replenishes rainwater to the collection chamber 32 through the collection pipe 36. At the initial stage of rainfall, the butterfly valve 33 is open, and the rainwater, containing more impurities, flows to the diversion chamber 31 and is discharged through the sewage pipe 35, achieving initial rainwater diversion and preventing impurities from contaminating subsequent treatment processes. During the middle stage of rainfall, the butterfly valve 33 closes, the water level in the collection chamber 32 rises, and excess rainwater is discharged into the diversion chamber 31 through the overflow channel 34, relieving water pressure in the collection chamber 32 and providing a stable water source for subsequent filtration.

[0045] Rainwater in the collection chamber 32 is transported to the centrifugal filter 2 via a fixedly connected conveying pipe 11 on one side. The centrifugal filter 2, as a primary filtration component, performs preliminary centrifugal filtration of the rainwater, removing larger particulate impurities. The filtered, qualified rainwater is then transported to the sedimentation tank 1 via a water supply pipe 13 in the middle of one side of the centrifugal filter 2. Wastewater generated during filtration is returned to the diversion chamber 31 via a return pipe 12 at the bottom of the centrifugal filter 2, and finally discharged through the sewage pipe 35. This process achieves preliminary purification and impurity separation of the rainwater, laying the foundation for subsequent advanced treatment.

[0046] The sedimentation tank 1 is divided into a sedimentation chamber and a clear water chamber by a partition 17. A filter screen 18 is installed at the bottom of the partition 17, and the spray end of the water supply pipe 13 is located at the bottom of the inner side of the sedimentation chamber. After the rainwater has undergone preliminary filtration, it enters the sedimentation chamber and undergoes natural sedimentation. The silt and some large particles in the rainwater settle at the bottom of the chamber, while the cleaner rainwater in the upper layer passes through the filter screen 18 and enters the clear water chamber for secondary filtration. The emptying pump 14 installed inside the sedimentation chamber can pump out the settled silt and impurities and discharge them to the diversion well chamber 31. The lift pump 15 inside the clear water chamber pumps the purified rainwater to the fine filter 4 for further deep treatment, realizing the graded sedimentation and quality-separated transportation of rainwater.

[0047] The fine filter 4 is internally divided into a fine filtration chamber 41 and an adsorption chamber 42. The fine filtration chamber 41 contains a sand filter box 43, a flexible mounting bracket 44, and a detachable fine filter element 10. The adsorption chamber 42 is filled with activated carbon particles. A water pump 45 is located at one end of the bottom, and a protective mesh box 46 is fixed to the pump's extraction end. After rainwater enters the fine filter 4, it first passes through the sand filter box 43, where the sand particles intercept small impurities. Then, it flows naturally into the fine filtration chamber 41, where it enters the fine filter element 10 under water pressure for further filtration, removing fine impurities. The filtered rainwater then enters the adsorption chamber 42, where it comes into full contact with the activated carbon particles. The activated carbon adsorbs odors, organic matter, and other harmful substances in the rainwater, achieving deep purification. Finally, the water pump 45 transports the deeply purified rainwater to the fire pool 5 through the drain pipe 16. The protective mesh box 46 prevents activated carbon particles from entering the water pump 45, ensuring stable equipment operation.

[0048] To ensure the stability of the fine filtration and adsorption effects, the device is equipped with a drive component 8, a swing component 7, and a stirrer 9. The drive component 8 is installed on one side of the fine filter 4, with its actuating end corresponding to the swing component 7 and connected to the stirrer 9. During the operation of the fine filter 10, the drive component 8 is activated, and its internal components rotate to drive the swing component 7, causing the swing component 7 to reciprocate to move the upper end of the fine filter 10. The fine filter 10 reciprocates and shakes on the elastic mounting frame 44, shaking off impurities adhering to its surface, keeping the filtration channel unobstructed, and improving filtration efficiency and water quality stability. At the same time, the drive component 8 synchronously drives the stirrer 9 to operate, which stirs the activated carbon particles in the adsorption chamber 42, loosening and mixing the activated carbon particles, avoiding local adsorption saturation, improving the adsorption and purification effect, and ensuring efficient removal of impurities from rainwater.

[0049] After deep purification, the rainwater is transported to the fire pool 5 for separate reuse: the first pump 51 inside the fire pool 5 can pump the rainwater to the external fire-fighting equipment for emergency fire water supply; the second pump 52 on the other side of the pool pumps some of the rainwater into the disinfection tank 6, which further disinfects and purifies the rainwater before it is transported to the roof water tank on the roof of the building through the drain pipe 61 for domestic use. It can also be used for non-potable purposes such as landscaping and car washing, thus realizing the integrated collection, deep treatment and multi-scenario utilization of rainwater, maximizing the efficiency of rainwater collection and treatment and the utilization rate of resources.

[0050] Reference Figure 7The bottom of the elastic mounting bracket 44 is provided with a sliding groove 441. A sliding seat 442 is slidably connected inside the sliding groove 441, and spring telescopic rods 443 are fixedly connected to both ends of the sliding groove 441. The bottom of the sliding seat 442 is installed and connected to the fine filter element 10. The fine filter element 10 includes a connecting plate 101 installed at the bottom of the sliding seat 442. Multiple sets of fine filter membrane tubes 102 are fixedly connected to the bottom of the connecting plate 101. A sealing plate is fixedly connected to the bottom end of the fine filter membrane tube 102. The sealing plate is connected to the top end of the adsorption chamber 42. Here, the length of the fine filter membrane tube 102 is greater than the distance between the connecting plate 101 and the sealing plate, which facilitates shaking to remove impurities. The fine filter membrane tube 102 is a polyvinylidene fluoride hollow fiber tube ultrafiltration membrane with high mechanical strength, resistance to gas wiping and forward and reverse washing. It is not easy to break or clog in the rainy season with high turbidity rainwater. It will not cause the membrane fibers to break or break when shaking.

[0051] The flexible mounting bracket 44 is fixedly connected to the fine filter 4 by bolts, and the connecting plate 101 is fixedly connected to the slide 442 by multiple bolts. When maintenance of the fine filter element 10 is required, multiple bolts can be manually removed to disassemble the flexible mounting bracket 44 and the fine filter element 10, thereby enabling quick replacement and cleaning of the fine filter element 10. Rainwater seeps into the fine filter membrane tube 102, filtering out fine impurities in the rainwater. The filtered rainwater can then flow along the internal tube of the fine filter membrane tube 102. The water enters the adsorption chamber 42 to achieve fine filtration of rainwater. When the swinging component 7 moves the connecting plate 101, it can drive the slide 442 to slide inside the slide groove 441. During this period, the slide 442 is reset by the elastic action of the spring telescopic rod 443, which can realize the reciprocating movement of the connecting plate 101, thereby driving multiple sets of fine filtration membrane tubes 102 to swing, which can shake off the impurities adhering to the fine filtration membrane tubes 102, keep the filtration smooth, and maximize the filtration efficiency and water quality stability.

[0052] Reference Figure 8 and Figure 9 The oscillating component 7 includes a slide rail 71 fixedly connected to the inner wall of the fine filter chamber 41. A slider 72 is slidably connected inside the slide rail 71. A U-shaped lever 74 is fixedly connected to one side of the slider 72. Spring telescopic rods 73 are fixedly connected to both sides of the slider 72. A lever 75 is fixedly connected to the bottom of the slider 72. The driving component 8 includes a connecting sleeve plate 85 fixedly connected to the inner wall of the fine filter chamber 41. A driving disk 83 is rotatably connected to the inner top of the connecting sleeve plate 85. A servo motor 81 is fixedly connected to one side of the fine filter 4. A rotating shaft 82 is fixedly connected to the output end of the servo motor 81. The rotating shaft 82 is fixedly connected to the driving disk 83. A lever 84 is fixedly connected to one side of the driving disk 83. The lever 84 corresponds to the lever 75.

[0053] The operation of the servo motor 81 drives the rotating shaft 82 to rotate. The rotating shaft 82 drives the drive disk 83 to rotate, which in turn drives the dial plate 84 to rotate. This causes the dial plate 84 to intermittently drive the dial block 75, which in turn causes the dial block 75 to drive the slider 72 to slide inside the slide rail 71. During this period, the slider 72 is reset by the elastic action of the spring telescopic rod 73, which drives the U-shaped dial 74 to reciprocate toggle the connecting disk 101.

[0054] Reference Figure 9 The agitator 9 includes a driven disk 91 rotatably connected to the bottom of the connecting sleeve 85. A turntable 92 is fixedly connected to one side of the driven disk 91, and a plurality of agitating rods 93 are fixedly connected to one side of the turntable 92. The driven disk 91 and the drive disk 83 are connected by a transmission belt 86.

[0055] When the drive disc 83 rotates, it can drive the driven disc 91 to rotate via the transmission belt 86. The rotating driven disc 91 can drive the turntable 92 to rotate, and the rotating turntable 92 can drive multiple stirring rods 93 to rotate. The multiple rotating stirring rods 93 can loosen and mix the activated carbon particles inside the adsorption chamber 42, improve the adsorption and purification effect, and maximize the removal effect of impurities in rainwater.

[0056] Working principle: The collection tank 3 is divided into a diversion chamber 31 and a collection chamber 32, which are connected by a butterfly valve 33. The municipal water supply network supplies water to the collection chamber 32 through the collection pipe 36. At the beginning of rainfall, the butterfly valve 33 opens, and the initial rainwater containing more impurities is discharged through the diversion chamber 31 and the sewage pipe 35. During the middle of rainfall, the butterfly valve 33 closes, and the excess rainwater in the collection chamber 32 is discharged into the diversion chamber 31 through the overflow ditch 34, ensuring a stable water source for subsequent treatment.

[0057] Rainwater from the collection chamber 32 enters the centrifugal filter 2 via the delivery pipe 11 for preliminary filtration to remove large particulate impurities. Qualified rainwater is sent to the sedimentation tank 1 via the water delivery pipe 13. The wastewater produced by filtration is returned to the diversion chamber 31 via the return pipe 12 and finally discharged through the sewage pipe 35, completing the preliminary purification and impurity separation.

[0058] Sedimentation tank 1 is divided into sedimentation chamber and clear water chamber by partition 17, and filter screen 18 is provided at the bottom of partition 17. After rainwater enters the sedimentation chamber and settles, the upper clear water passes through the filter screen 18 and enters the clear water chamber; the empty pump 14 pumps the settled impurities to the diversion well chamber 31 for discharge, and the lift pump 15 pumps the rainwater in the clear water chamber to the fine filter 4 for deep treatment;

[0059] The fine filter 4 is divided into a fine filtration chamber 41 and an adsorption chamber 42. The fine filtration chamber 41 is equipped with a sand filter box 43, a flexible mounting frame 44, and a fine filter element 10. The adsorption chamber 42 is filled with activated carbon. After two stages of fine filtration through the sand filter box 43 and the fine filter element 10, rainwater enters the adsorption chamber 42 and undergoes deep adsorption by the activated carbon. Finally, it is pumped by the water pump 45 through the drain pipe 16 to the fire pool 5. The protective screen box 46 ensures the stability of the equipment.

[0060] After the drive unit 8 is started, the drive swinging unit 7 reciprocates to move the fine filter 10, causing it to shake on the elastic mounting frame 44, shaking off surface impurities and keeping the filtration smooth; at the same time, the drive unit 8 synchronously drives the stirring unit 9 to stir the activated carbon particles in the adsorption chamber 42 to avoid adsorption saturation and improve the purification effect.

[0061] The purified rainwater is stored in fire pool 5, and pump 51 delivers it to fire-fighting equipment for emergency water supply. Pump 52 pumps some rainwater into disinfection tank 6 for disinfection, and then sends it to rooftop water tank via drain pipe 61 for domestic use. It can also be used for landscaping, car washing, and other purposes, realizing multi-purpose utilization of rainwater. This integrated design not only reduces the purchase and operation costs of tap water in the park at the micro level, but also reduces the dependence on municipal fire protection and tap water networks at the macro level, reducing government investment in infrastructure construction. This makes municipal pipeline planning more economical and flexible, deeply aligning with the guiding principles of "sponge city" and contributing to the overall planning of a low-carbon and environmentally friendly modern city.
