[0040] Embodiment 1, as Figure 1 , 3As shown in Figure 5, medical wastewater is poured into the filter chamber 11 through the inlet frame 14 and the filter screen 15. The servo motor 12 is turned on to drive the threaded rod 13 to rotate. The filter element 17 can filter larger substances and particles in the wastewater. The two sets of filter elements 17 can achieve the effect of filtering wastewater. At the same time, the servo motor 12, in cooperation with the threaded rod 13, drives the cleaning component 2 to move up and down. The mounting plate 201 moves up and down on the outside of the threaded rod 13, driving the cleaning brush 203 to slide on the outside of the filter element 17 to wipe the surface of the filter element 17.

[0041] Example 2, as Figure 1 As shown, ozone is delivered to the interior of the disinfection chamber 1 through the cooperation of the air inlet pipe 5 and the aeration pipe 7 for disinfection. The gas moves inside the wastewater. When the gas moves to the top of the disinfection chamber 1, the ozone is absorbed by the cooperation of the air pump 19 and the first recovery pipe 18. Then, the ozone is delivered to the interior of the air inlet pipe 5 through the second recovery pipe 20 for reuse, reducing gas leakage and reusing resources.

[0042] Working principle: Medical wastewater is poured into the filter chamber 11 through the inlet frame 14 and the filter screen 15. The servo motor 12 is turned on to drive the threaded rod 13 to rotate. The filter element 17 can filter larger substances and particles in the wastewater. The two sets of filter elements 17 can achieve the effect of filtering wastewater. At the same time, the servo motor 12, in cooperation with the threaded rod 13, drives the cleaning component 2 to move up and down, causing the cleaning brush 203 to slide on the outside of the filter element 17 and wipe the surface of the filter element 17. Meanwhile, the gear 208 meshes with the rack 21 and rotates. The worm gear 206 drives the worm wheel 205 to rotate, so that the cleaning brush 203 rotates and moves up and down at the same time, wiping the filter element 17 more thoroughly and with a fast filtration rate. At the same time, a sealing groove is set at the bottom of the filter chamber 1, and a sealing chamber is set inside the sealing groove. The threaded rod 13 passes through the sealing chamber and is connected to the filter chamber 1 and the sealing chamber through the sealing ring.

[0043] The rotation of the threaded rod 13 rotates inside the filter bin 11 through two groups of annular frames 23 and annular sliding rails 22, the annular sliding rails 22 drive the wavy grooves 24 to rotate, the wavy grooves 24 slide relative to the drive rod 303, the drive rod 303 moves up and down, the inner sleeve 305 moves up and down inside the outer sleeve 302 through the support rod 304, the liquid inlet 306 moves to the inside of the liquid storage bin 301, the disinfectant inside the inner sleeve 305 enters the inside of the filter bin 11 to disinfect, then the inner sleeve 305 is pulled down through the cooperation of the drive rod 303 and the support rod 304, the liquid inlet 306 moves to the outer sleeve 301, the piston 307 blocks the inside of the outer sleeve 301, the disinfectant water cannot fall, the inside can be uniformly added, and the waste of disinfectant is reduced

[0044] But after the wastewater disinfection and filtration are completed, the ozone is transported to the inside of the aeration pipe 7 through the connection of the gas inlet pipe 5 and the external gas pipe, the gas in the aeration pipe 7 can be transported to the inside of the filter bin 11 through a plurality of gas nozzles, and the transmission shaft 4 drives the aeration pipe 7 to rotate, so that the aeration pipe 7 drives the nozzles to rotate, improves the full contact of the bubbles and the water, and can disinfect the water again.

[0045] Finally, it should be noted that the above content is only used to illustrate the technical solutions of the present application, and is not a limitation on the protection scope of the present application. Simple modifications or equivalent replacements of the technical solutions of the present application by those skilled in the art do not deviate from the essence and scope of the technical solutions of the present application.
