[0025] like Figure 1 As shown, an embodiment of the utility model provides a rainwater purification, treatment and reuse system.

[0026] A rainwater purification, treatment and reuse system includes a sedimentation tank 1, a treatment tank 2, a water reservoir 3 and a water pipe 4. The sedimentation tank 1, the treatment tank 2 and the water reservoir 3 are connected in sequence. A water inlet pipe 5 is provided at one end of the sedimentation tank 1, and a sludge sedimentation part 6 is provided at the bottom of the sedimentation tank 1. A perforated wall 7 is provided between the sedimentation tank 1 and the treatment tank 2, and a plurality of through holes 8 are provided on the perforated wall 7. A quartz sand layer 9 and an activated carbon layer 10 are provided in sequence in the treatment tank 2. A water inlet 11 is provided between the treatment tank 2 and the water reservoir 3. The water pipe 4 extends from the top of the water reservoir 3 to the lower end of the water reservoir 3. A water level monitor 12 is provided in the water reservoir 3, and a drainage pipe 13 is provided at the bottom of the water reservoir 3.

[0027] The utility model is provided with a water inlet pipe 5 at one end of the sedimentation tank 1, and a sludge sedimentation part 6 is provided at the bottom of the sedimentation tank 1. The rainwater entering from the water inlet pipe 5 is first precipitated, and the large particles of mud and sand and other impurities in the water flow are naturally settled by gravity, so as to preliminarily purify the water quality. The quartz sand layer 9 and the activated carbon layer 10 in the treatment tank 2 are used as filter media. The quartz sand layer 9 removes suspended matter and some organic matter, and the activated carbon layer 10 further adsorbs dissolved organic matter and residual chlorine, etc., which significantly improves the water quality. The water reservoir 3 has a built-in water level monitor 12, which displays and controls the water level in real time to avoid overflow or drying up. The utility model realizes the effective collection, purification and reuse of rainwater, can effectively separate solid particles in rainwater, and ensures that the water quality meets the reuse standard through multi-stage purification.

[0028] In the rainwater purification, treatment and reuse system described in this embodiment, the bottom of the sedimentation tank 1 is recessed downward to form the sludge settling section 6, and a sewage outlet 14 is provided on the inner wall of the sludge settling section 6. Specifically, by designing the bottom of the sedimentation tank 1 to be recessed downward to form the sludge settling section 6 and providing the sewage outlet 14 on the inner wall thereof, the centralized sedimentation of solid particles such as silt and sand and subsequent cleaning are facilitated, the sludge removal process is simplified, and the maintenance efficiency of the system is improved.

[0029] In the rainwater purification, treatment and reuse system described in this embodiment, at least two baffles 15 are provided in the sedimentation tank 1. The baffles 15 are staggered and are all arranged between the sludge sedimentation section 6 and the perforated wall 7. A first sewage guide slope 16 is provided at one end of the sludge sedimentation section 6 close to the perforated wall 7. The first sewage guide slope 16 is arranged between the sludge sedimentation section 6 and the perforated wall 7. The first sewage guide slope 16 is inclined toward one end of the sludge sedimentation section 6, and the baffles 15 are all located on top of the first sewage guide slope 16. Specifically, providing multiple staggered baffles 15 and sewage guide slopes 16 in the sedimentation tank 1 can increase the length of the water flow path, extend the hydraulic retention time, and facilitate the removal of suspended matter to a greater extent and improve the sedimentation effect.

[0030] In the rainwater purification, treatment and reuse system described in this embodiment, a second sewage guide slope 17 is provided between the water inlet pipe 5 and the sludge settling section 6. The second sewage guide slope 17 is inclined toward one end of the sludge settling section 6. Specifically, the design of the second sewage guide slope 17 between the water inlet pipe 5 and the sludge settling section 6 can guide the incoming rainwater to be more evenly distributed in the sedimentation tank 1, avoiding the resuspension of settled matter caused by excessive local flow velocity, thereby improving sedimentation efficiency.

The quartz sand layer 9 is disposed between the sedimentation zone 18 and the filtration zone 19, and the activated carbon layer 10 is disposed between the filtration zone 19 and the outlet zone 20. Specifically, the treatment pool 2 is divided into the sedimentation zone 18, the filtration zone 19, and the outlet zone 20, each of which performs a different purification task. In particular, the combined use of the quartz sand layer 9 and the activated carbon layer 10 can significantly improve the water purification level and ensure that the outlet water meets the usage standards.

[0032] In the rainwater purification, treatment and reuse system described in this embodiment, an electrically controlled valve 21 is provided in the water inlet 11. Specifically, when the valve 21 is opened, rainwater purified by the treatment tank 2 flows into the water storage tank 3. When the water level reaches a set value, the valve 21 is automatically closed to stop water storage.

[0033] In the rainwater purification, treatment and reuse system described in this embodiment, the volume of the water reservoir 3 is larger than the volume of the sedimentation tank 1 and the volume of the treatment tank 2. Specifically, the larger volume of the water reservoir 3 than the other components means that it can store more purified rainwater, increasing the system's water storage capacity and ensuring sufficient water supply even during rainless periods.

[0034] In the rainwater purification and reuse system described in this embodiment, the shell of the water storage tank 3 is made of stainless steel. Specifically, stainless steel is corrosion-resistant, durable, and easy to clean, and is suitable for long-term storage of rainwater.

[0035] In the rainwater purification and reuse system described in this embodiment, the water pipe 4 is connected to a water pump 22. Specifically, the water pump 22 is turned on to pump water out of the water reservoir 3 using its suction force. Furthermore, the start and stop of the water pump 22 can be automatically controlled based on actual demand and water level changes.

[0036] In the rainwater purification, treatment and reuse system described in this embodiment, a plurality of sensors 23 are provided within the treatment tank 2. Specifically, the plurality of sensors 23 provided within the treatment tank 2 can monitor changes in water quality, such as pH value and dissolved oxygen content, in real time, and promptly feed back the data to the control system so that corresponding adjustments can be made to ensure stable operation of the entire system.
