[0019] A rack lifting structure is provided at one end of the power box 2, and the rotating shaft 2 7 extends to the inside of the power box 2 and is connected to the rack lifting structure by power. A matrix layer 10 is installed at the movable end of the rack lifting structure, and the bottom end of the matrix layer 10 is in contact with the top end of the tank body 1. By lifting the matrix layer 10, not only can the changes in the situation inside the stuffing box 3 be intuitively seen so that adjustments can be made at any time, but also subsequent backwashing operations are convenient, effectively preventing dirt accumulation;

[0020] A water pump 11 is installed on the surface of the pool body 1, and a backwash pipe 12 is installed at the bottom of the pool body 1. The water outlet of the water pump 11 is connected to the water inlet of the backwash pipe 12. A plurality of anti-backflow nozzles 13 are installed on the outer surface of the backwash pipe 12. By installing the anti-backflow nozzles 13 in layers, the flushing effect can be greatly improved, and the amount of flushing water can be saved at the same time.

[0021] A sewage pipe 14 is installed on the outer wall of one side of the tank body 1. A sewage treatment tank 15 is arranged at one end of the sewage pipe 14 away from the tank body 1. The sewage treatment tank 15 can effectively remove impurities and pollutants in the water, improve water quality, greatly reduce the degree of water pollution, maintain a good water environment in the city and even the basin, and protect people's health.

[0022] A control button 16 is installed on the surface of the pool body 1, and the output end of the control button 16 is electrically connected to the gear transmission mechanism and the input end of the water pump 11;

[0023] The gear transmission mechanism includes two rotating shafts 501 rotatably mounted on the surface of the pool body 1, and the two rotating shafts 501 are rotatably connected through a gear 5. A motor 4 for driving one of the rotating shafts 501 to rotate is installed on one side of the surface of the pool body 1. The input end of the motor 4 is electrically connected to the output end of the control button 16. The two rotating shafts 501 both drive the rotating shaft 7 to rotate through the belt 6. By turning on the motor 4, the rotating shaft 501 is driven by the motor 4 to rotate. At this time, the gear 5 also rotates synchronously with the movement direction of the rotating shaft 501. At this time, 6 will also drive 7 to move, thereby laying a foundation for the subsequent lifting movement of the matrix layer 10;

[0024] The rack lifting structure includes a gear 2 8 rotatably mounted at one end of the power box 2, one end of the rotating shaft 2 7 extends to the inside of the power box 2 and is fixedly connected to the center point of the gear 2 8, and rack monomers 9 are slidably mounted on the outer walls of both sides of the stuffing box 3. The rack monomers 9 and the gear 2 8 are meshed with each other, and the rotation of the rotating shaft 2 7 drives the gear 2 8 to rotate in the same direction. At this time, the rack monomer 9 meshing with the gear 2 8 makes an ascending or descending action, thereby completing the ascending and descending movement of the matrix layer 10, which is convenient for the subsequent backwashing operation;

[0025] The anti-backflow nozzle 13 includes a water inlet pipe 1301 installed on the outer surface of the backwash pipe 12, a water outlet pipe 1302 is arranged on the outer wall of one side of the anti-backflow nozzle 13, a spring 1303 is installed on the top of the anti-backflow nozzle 13, and a water retaining ball 1304 is installed on the bottom end of the spring 1303, the water retaining ball 1304 is in contact with the water inlet pipe 1301 and the outer diameter of the water retaining ball 1304 is larger than the inner diameter of the water inlet pipe 1301, when water flows into through the water inlet pipe 1301, the water retaining ball 1304 will be lifted up due to the impact force, and the spring 1303 will be compressed and flow out through the water outlet pipe 1302, when the water pump 11 is turned off, the spring 1303 will block the water retaining ball 1304 above the water inlet pipe 1301 due to its elasticity, thereby effectively preventing sewage from flowing back, making the backwash pipe 12 more firm and durable, extending the service life of the backwash pipe 12, and improving energy utilization efficiency;

[0026] A drain valve 1501 is installed at the bottom of the sewage treatment tank 15, and a filter membrane 1504 is installed at one end of the sewage treatment tank 15, and the interior of the sewage treatment tank 15 above the filter membrane 1504 is filled with activated carbon 1503 and coarse sand 1502 in sequence. When sewage enters the sewage treatment tank 15 through the sewage pipe 14, the sewage first flows through the coarse sand 1502, then to the activated carbon 1503, and finally to the filter membrane 1504. At this time, opening the drain valve 1501 can directly discharge the filtered water, which saves water resources while protecting the ecological environment.

[0027] When the embodiment of the present application is in use, first, the staff turns on the gear transmission mechanism through the control button 16. At this time, the belt 6 wrapped around the gear transmission mechanism starts to rotate, and the belt 6 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the rack lifting structure to move. When the rack lifting structure starts to slide upward, the matrix layer 10 installed on the top of the rack lifting structure also moves upward. By lifting the matrix layer 10, it is convenient for the staff to perform backwashing operations, and it is automatic lifting without the need for the staff to lift it manually, saving the staff's time and labor and ensuring the personal safety of the staff. Then, the water pump 11 is turned on, and the water flows along the backwash pipe 12 through the anti-backflow nozzle 13 to start the backwashing operation. In addition, the water retaining ball 1304 installed in the anti-backflow nozzle 13 can effectively prevent the pollutants from flowing back, thereby protecting the safety of 12 and improving the service life. Finally, while flushing, the sewage continuously enters the sewage treatment tank 15 through the sewage pipe 14, and then is filtered through the coarse sand 1502, the activated carbon 1503, and the filter membrane 1504. The drain valve 1501 is opened to discharge the filtered water.
