[0041] Working principle: When in use, domestic sewage enters the sedimentation tank 2 through the transparent water inlet pipe 3 for sedimentation and filtration. The solar panel 13 and the solar converter 12 cooperate with each other to convert solar energy into electrical energy and store it in the battery 11. The electricity stored in the battery 11 can power the ultraviolet disinfection lamp 10. The ultraviolet disinfection lamp 10 is started by controlling the switch 14. The ultraviolet light emitted by the ultraviolet disinfection lamp 10 can pass through the transparent water inlet pipe 3 to disinfect and sterilize the sewage passing through the transparent water inlet pipe 3, thereby utilizing solar power generation for disinfection power supply, effectively saving electricity resources and reducing electricity costs. The connecting wire 15 can be connected to the mains to prevent it from being used as a backup power supply option when there is insufficient sunlight. After ultraviolet disinfection, the sewage enters the sedimentation tank 2, and the sewage enters the bottom of the tank body 22 through the inlet 23. The multiple triangular sedimentation plates 24 are in a wave structure. When the sewage impacts the triangular sedimentation plates 24, part of the sediment can be blocked in the depressions between the triangular sedimentation plates. When the sewage passes through the filtration When the plate 28 is used, the filter plate 28 can filter solid impurities in the sewage. Since the sewage will be simply filtered before entering the disinfection step, large impurities will not enter the disinfection device, so that the solid impurities in the sewage can be effectively precipitated. Sodium hypochlorite disinfectant is added to the sedimentation tank 2 through the disinfectant addition pipe 20, and the disinfectant can further disinfect the sewage. The sewage in the sedimentation tank 2 flows into the reservoir 7 through the overflow pipe 9. The water in the reservoir 7 can be recycled as irrigation or dust removal spray water. When the device needs to be cleaned, the water supply is stopped, and the sediment and sewage are discharged from the sedimentation tank 2 through the sewage pipe 25. The booster water pump 18 is started, and the booster water pump 18 draws water from the reservoir 7 through the hose 19, and then transports the water to the multiple spray pipes 16 through the serpentine pipe 17. The high-pressure water flow sprayed by the multiple spray pipes 16 can flush the filter plate 28, so that the treated sewage can be used to clean the device, reducing water costs and avoiding the problem of water resource waste.

[0042] When it is necessary to open the sealing cover 5, the motor 33 is controlled to rotate forward, and the motor 33 drives the winch 34 to rotate to reel in the steel rope 36. The steel rope 36 pulls the sealing cover 5, causing the sealing cover 5 to rotate around the hinge, thereby opening the sealing cover 5. The motor 33 can be self-locking, thereby keeping the sealing cover 5 in one position and not moving, thereby releasing the sealing of the sealing cover 5 on the pool body 22, and the provided hose 19 can ensure that the booster water pump 18 does not hinder the deflection of the sealing cover 5. When it is necessary to close the sealing cover 5, the motor 33 is controlled to rotate in the reverse direction, and the pool body 22 is re-sealed under the action of the sealing cover 5's own weight.
