The output end of the first motor 12 is fixedly connected to one end of the rotating shaft 2. By setting the filter screen 8, it is convenient to filter a large amount of impurities contained in the sewage, so that the sewage enters the bottom of the sewage treatment tank 1, and the impurities are retained in the filter screen 8. The first motor 12 is turned on through the control panel 26 to drive the rotating shaft 2 and the special-shaped stirring rod 3 to rotate, and then drive the adapter sleeve 4, the connecting rod 5 and the mounting seat 6 to rotate, thereby driving the filter screen 8 to make a circular motion, so that the impurities in the sewage are evenly filtered in the filter screen 8, avoiding filtering only in one place, causing the filter mesh 10 to be blocked and affecting the filtering efficiency. The special-shaped stirring rod 3 rotates to mix the disinfectant and the sewage, so that the disinfectant and the sewage are fully integrated, so that the sewage inside the sewage treatment tank 1 can be quickly disinfected evenly.

[0025] Four ultraviolet lamps 16 are installed on the inner bottom wall of the sewage treatment box 1, and a bidirectional screw rod 17 and a slide rod 18 are installed on the inner wall of the sewage treatment box 1 respectively. The threads of the bidirectional screw rod 17 on the surfaces of the two ends of the axial direction are opposite, and the rod body of the bidirectional screw rod 17 is respectively threadedly connected with a first moving block 19 and a second moving block 20, and the rod body of the slide rod 18 is slidably connected with a third moving block 21 and a fourth moving block 22. A cleaning wipe 23 is installed on the lower surface of the first moving block 19, the second moving block 20, the third moving block 21 and the fourth moving block 22. The bidirectional screw rod 17 is rotatably connected to the sewage treatment box 1, and the slide rod 18 is fixedly connected to the sewage treatment box 1. A connecting rod 24 is fixed between two adjacent ones of the four cleaning wipes 23, and the output end of the second motor 25 is connected to the bidirectional screw rod 17. One end of the screw rod 17 is fixedly connected, and the first motor 12, the second motor 25 and the four ultraviolet lamps 16 are electrically connected to the control panel 26. By setting up four ultraviolet lamps 16, the sewage inside the sewage treatment tank 1 is further disinfected, thereby improving the efficiency and effect of sewage treatment disinfection. The second motor 25 is regularly turned on through the control panel 26 to drive the bidirectional screw rod 17 to rotate forward and then reverse, thereby driving the first moving block 19, the second moving block 20, the third moving block 21, the fourth moving block 22, the connecting rod 24 and the four cleaning wipes 23, and reset after moving to the middle. In the process of moving to the middle, the four cleaning wipes 23 clean the surface of the four ultraviolet lamps 16 to keep the outer wall of the ultraviolet lamp 16 clean to avoid affecting the disinfection effect.

[0026] A rotating liquid inlet component 13 and a limiting component 14 are respectively installed on the sewage treatment box 1. The rotating liquid inlet component 13 includes a support column 1301 welded to the upper surface of the sewage treatment box 1. The upper surface of the support column 1301 is rotatably connected with a mounting platform 1302. The upper surface of the mounting platform 1302 is installed with a liquid inlet pipe 1303. The lower surface of the mounting platform 1302 is provided with a rectangular groove 15. The limiting component 14 includes a telescopic support cylinder 1401 welded to the upper surface of the sewage treatment box 1. The interior of the telescopic support cylinder 1401 is slidably connected with a telescopic limiting rod 1402. The outer wall of the telescopic support cylinder 1401 is threadedly connected with a fixing bolt 1403. The tail of the fixing bolt 1403 abuts against the telescopic limiting rod 1402. The telescopic end of the telescopic limiting rod 1402 abuts against the inside of the rectangular groove 15. By arranging a rotatable liquid inlet pipe 1303 and a detachable filter screen 8, it is convenient to take out and clean the filter screen 8.

[0027] Working principle: When in use, the sewage is connected through the liquid inlet pipe 1303 to flow into the sewage treatment tank 1. When the sewage passes through the filter screen 8, the filter screen 8 filters a large amount of impurities contained in the sewage, so that the sewage enters the bottom of the sewage treatment tank 1, and the impurities remain in the filter screen 8. The first motor 12 is turned on through the control panel 26 to drive the rotating shaft 2 and the special-shaped stirring rod 3 to rotate, and then drive the adapter sleeve 4, the connecting rod 5 and the mounting seat 6 to rotate, thereby driving the filter screen 8 to make a circular motion, so that the impurities in the sewage are evenly filtered in the filter screen 8, avoiding filtering only in one place, causing the filter mesh 10 to be blocked and affecting the filtering efficiency, pouring the disinfectant into the sewage treatment tank 1, and the special-shaped stirring rod 3 rotates to mix the disinfectant and the sewage, so that the disinfectant and the sewage are fully integrated, so that the sewage inside the sewage treatment tank 1 can be quickly and evenly disinfected, and the four ultraviolet lamps 16 are turned on to the sewage treatment tank 1. The internal sewage is further disinfected, which improves the efficiency and effect of sewage treatment and disinfection. The second motor 25 is regularly turned on through the control panel 26 to drive the bidirectional screw 17 to rotate forward and then reverse, thereby driving the first moving block 19, the second moving block 20, the third moving block 21, the fourth moving block 22, the connecting rod 24 and the four cleaning wipes 23, and they are reset after moving to the middle. In the process of moving to the middle, the four cleaning wipes 23 clean the surfaces of the four ultraviolet lamps 16 to keep the outer walls of the ultraviolet lamps 16 clean to avoid affecting the disinfection effect. When the filter screen 8 needs to be taken out for cleaning, unscrew the fixing bolt 1403, pull the telescopic limit rod 1402 to move into the telescopic support cylinder 1401, thereby releasing the limit on the mounting platform 1302, rotate the mounting platform 1302 so that the liquid inlet pipe 1303 is in a vertical state, and directly take out the filter screen 8 from the mounting seat 6, so as to deeply clean the impurities filtered out from the filter mesh 10.
