The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model.

[0025] Referring to Figure 1 The utility model discloses a rainwater treatment device, including water storage pool 10, clean water pool 20 and filter piece 211, water storage pool 10 is equipped with having first water inlet and first water outlet, and first water inlet is used to import water flow, and first water outlet is used to export water flow, clean water pool 20 is equipped with second water inlet and second water outlet, and second water inlet is communicated with first water outlet through water delivery pipe 21, and second water outlet is communicated with outside, and filter piece 211 is arranged in water delivery pipe 21.

[0026] On the basis of the above structure, water storage pool 10 and clean water pool 20 can be buried underground to save the space position on the ground, then the first water inlet is externally communicated, when raining, rainwater can enter water storage pool 10 through the first water inlet, when the initial rainwater stays in water storage pool 10, larger particle impurities, silt and the like can naturally deposit to the bottom under the action of gravity, and the deposition process can remove most of the solid impurities with larger particle size in rainwater, so that rainwater is preliminarily purified, and the load of subsequent treatment is reduced.

[0027] Then the rainwater preliminarily purified is transported to clean water pool 20 through water delivery pipe 21, since filter piece 211 is arranged on water delivery pipe 21, the filter piece 211 can intercept and remove the residual suspended particles, small particle size impurities and the like in rainwater, further reduce the turbidity of rainwater, and rainwater is more deeply purified.

[0028] Finally, after the rainwater after deposition and filtration enters clean water pool 20, some small impurities that have not been completely removed can continue to deposit during the stay in clean water pool 20, so that the water quality is further purified, and at the same time, since the water in clean water pool 20 has a relatively small contact area with air, the entry of external pollutants can be reduced, the risk of secondary pollution is reduced, and the water quality is further improved.

[0029] Because the rainwater in the clean water pool 20 is purified multiple times, the water quality is relatively better, so it can be applied to diversified recycling needs, such as being used in scenarios with high water quality requirements, such as flushing toilets, washing cars, and landscape water replenishment, thereby indirectly expanding the application range of rainwater recycling.

[0030] It should be noted that the filter 211 in this embodiment can be a filter screen or a filter membrane, which can be installed in the water conveying pipe 21 by screwing or welding to achieve filtration. Alternatively, a filter can be installed inside or outside the water conveying pipe 21 to achieve filtration.

[0033] Specifically, because rainwater may carry various bacteria, viruses, and microorganisms, etc., in the conveying process, suitable conditions can promote the proliferation of these microorganisms, affecting water quality. Therefore, in this embodiment, a dosing device is provided, which is filled with a disinfectant. The dosing device 212 is in communication with the water conveying pipe 21 to release the disinfectant into the water conveying pipe 21. The disinfectant inside the dosing device 212 can be released into the water conveying pipe 21. The dosing device 212 releases disinfectants such as chlorine dioxide and sodium hypochlorite, effectively killing these microorganisms, preventing their growth in the pipeline, ensuring water quality safety during rainwater conveying, reducing the risk of water quality deterioration due to excessive microorganisms, and indirectly improving water quality.

[0034] Of course, the dosing device 212 in this embodiment can also be filled with a coagulant, such as polyaluminum chloride, aluminum sulfate, or polyaluminum ferric chloride, to remove suspended impurities, colloidal substances, etc. in water by releasing coagulants, reduce water turbidity, improve water clarity, and improve water quality.

[0035] It should be noted that the dosing device 212 in this embodiment can be a metering pump dosing device 212, which is composed of a metering pump, a medicine tank, a controller, etc. The medicine tank is filled with a disinfectant, and the metering pump is used to control the output flow of the disinfectant and deliver the disinfectant into the water conveying pipe 21. Of course, other devices for releasing disinfectants can also be used.

[0036] Further, the first water pump 221, the air pressure tank 222 and the drain pipe 22 are further included, and the drain pipe 22 is arranged at the second water outlet, and the first water pump 221 and the air pressure tank 222 are communicated with the drain pipe 22 respectively.

[0037] Specifically, the first water pump 221 in the embodiment is selected from the existing variable frequency water pump, when the water in the clean water pool 20 needs to be pumped out, the first water pump 221 starts to work, and the water is transported to the outside through the drain pipe 22, with the water transportation, the system pressure gradually rises, when the water supply pressure of the first water pump 221 appears instantaneous change or the pressure fluctuation caused by the start and stop of the water using equipment, the air pressure tank 222 can quickly respond, and the pressure change is buffered by releasing or storing water, so that the system pressure is maintained in a relatively stable range, avoiding damage to the system caused by too high or too low pressure.

[0038] As preferred, the air pressure tank 222 in the embodiment can be selected from the existing diaphragm type air pressure tank 222, which divides the tank into a gas chamber and a water chamber by using a rubber diaphragm, when the system pressure rises, the water enters the water chamber, and the gas in the gas chamber is compressed; when the system pressure decreases, the gas in the gas chamber expands, and the water in the water chamber is pressed out, so as to maintain the stability of the system pressure; or a gas bag type air pressure tank 222 is selected, which has a rubber air bag inside, the gas is filled into the air bag, and the water is between the air bag and the tank body, when the system pressure changes, the air bag will expand or contract accordingly, so as to store and release the water, and adjust the system pressure.

[0039] More specifically, the disinfecting member is arranged on the drain pipe 22, and the disinfecting member is communicated with the drain pipe 22, when the water flows through the disinfecting member, the disinfecting member can effectively kill the microorganisms breeding in the water, further improving the water safety; at the same time, it can also avoid the formation of biofilm in the pipeline, causing pipeline blockage and water quality deterioration and other phenomena, further improving the water quality of the rainwater transported to the outside.

[0040] It should be noted that the disinfecting member in the embodiment can be selected from the existing ultraviolet disinfection device, which is communicated with the drain pipe 22, so that the ultraviolet light emitted by the ultraviolet disinfection device can enter the drain pipe 22 to disinfect the water; of course, a chlorine dioxide generator can also be selected, which releases chlorine dioxide gas into the water to quickly kill the microorganisms in the water to achieve disinfection.

[0041] As preferred, the disinfecting member is an ultraviolet disinfection device, compared with other disinfection devices, the ultraviolet disinfection device can achieve very high disinfection efficiency in a short time, and the disinfection is faster; in addition, ultraviolet disinfection is a physical disinfection method, which does not add any chemical substances to the water during the disinfection process, and does not produce harmful disinfection by-products, and does not pollute the water quality and the environment, and at the same time, the water in the drain pipe 22 is disinfected without secondary pollution to the water.

[0042] Further, the water inlet pipe 30 is provided with a guide inlet 31 and a first guide outlet 32, the guide inlet 31 is communicated with the outside, and the first guide outlet 32 is communicated with the water storage pool 10.

[0043] On the basis of the structure, the water inlet pipe 30 provides a flowing track for the rainwater, so that the rainwater can be guided into the water storage pool 10 according to the predetermined channel. Since the water inlet pipe 30 is provided with the sewage interception member 34, the sewage interception member 34 can intercept various impurities such as silt, leaves, garbage and the like carried by the water, so as to preliminarily filter the rainwater entering the water storage pool 10. Meanwhile, the impurities can be prevented from blocking or damaging the water inlet pipe 30, so as to prolong the service life of the water inlet pipe 30.

[0044] It should be noted that the sewage interception member 34 in the embodiment can be a sewage interception basket, which is hung in the water inlet pipe 30 by a lifting rope, so as to intercept larger impurities such as leaves or household garbage, and prevent the impurities from entering the water storage pool 10 with the rainwater. Then, the sewage interception member 34 can be pulled out by the staff for cleaning at regular intervals. Of course, the sewage interception member 34 can also be a grid or a filter screen for garbage, and the sewage interception member 34 can be cleaned at regular intervals, so as to prevent the sewage interception member 34 from being blocked by the impurities for a long time and affecting the normal use.

[0045] Further, the water inlet pipe 30 is provided with a second guide outlet 33, the second guide outlet 33 is located between the guide inlet 31 and the first guide outlet 32, and the second guide outlet 33 is provided with a flow discarding filter member 35.

[0046] Specifically, since the end wall of the second guide outlet 33 is lower than the end wall of the first guide outlet 32, the impurities in the initial rainwater are more. At this time, the impurities in the water flow will flow to the second guide outlet 33 with a relatively lower position under the action of gravity and the water flow, and then flow out from the second guide outlet 33 with a lower position. The initial rainwater flowing out from the second guide outlet 33 is guided to the flow discarding filter member 35 for treatment, so as to realize efficient flow discarding, and prevent the initial rainwater with relatively high turbidity from entering the water storage pool 10 through the first guide outlet 32 to pollute the stored rainwater.

[0047] In addition, due to the existence of the flow discarding filter member 35, the initial rainwater flowing out from the second guide outlet 33 can be filtered in time. The rainwater after the filtration has a greatly reduced content of impurities and pollutants, reduces the risk of blocking and corrosion of subsequent pipelines and equipment, and ensures the stable operation of the entire device.

[0048] It should be noted that the flow discarding filter member 35 in the embodiment can be a filter screen, a grid or an adsorption type filter member 211, so as to intercept and filter the impurities at the second guide outlet 33.

[0049] Further, the water storage pool 10 is also provided with a sewage pump 11 and a sewage pipe 12, the sewage pump 11 is arranged at the bottom of the water storage pool 10 and is communicated with the outside through the sewage pipe 12.

[0050] Specifically, during the rainwater collection process, a large amount of impurities such as silt and particulate matter will accumulate at the bottom of the water storage pool 10 over time, at this time, the staff can start the sewage pump 11 at the bottom of the water storage pool 10 regularly, and the impurities deposited at the bottom are sucked up by the sewage pump 11 and discharged to the outside through the sewage pipe 12, so as to prevent the impurities from accumulating too much at the bottom of the pool and affecting the effective volume and water quality of the water storage pool 10.

[0051] It should be noted that the sewage pump 11 can be selected from existing submersible sewage pumps 11, automatic stirring sewage pumps 11, or non-clogging sewage pumps 11.

[0052] More specifically, the water storage pool 10 is also provided with a second water pump 13, and the second water pump 13 is communicated with the water conveying pipe 21, so that the rainwater stored in the water storage pool 10 can be introduced into the clean water pool 20 through the water conveying pipe 21.

[0053] As a preferred, the second water pump 13 can be selected from existing centrifugal pumps, axial flow pumps or mixed flow pumps.

[0054] In addition, the device also includes a device room 40, which is arranged between the water storage pool 10 and the clean water pool 20, and the filter, the disinfection device, the dosing device 212, the first water pump 221 or the air pressure tank 222 and other equipment or pipelines can be arranged in the device room 40 during assembly, so as to facilitate unified maintenance and management.

[0055] In addition, the device room 40 is arranged adjacent to the water storage pool 10 and the clean water pool 20, which shortens the length of the connecting pipeline between the equipment in the device room 40 and the two pools, reduces the pipeline laying cost and land occupation area, and also facilitates the installation, maintenance and repair of the pipeline.

[0056] More specifically, since the bottom wall or the side wall of the water storage pool 10 will have silt or dirt after long-term use, it needs to be cleaned regularly to ensure that the water in the pool is relatively clean during storage, so the embodiment also has a flushing pipe, one end of which is communicated with the clean water pool 20, and the other end is communicated with the water storage pool 10, so that the clean water in the clean water pool 20 can be introduced into the water storage pool 10 through the flushing pipe to clean it regularly, so that the pool is relatively clean, thereby helping to improve the water quality of the rainwater in the water storage pool 10, and also fully utilizing the rainwater recovered in the clean water pool 20 to improve the utilization rate of the rainwater after recovery.
