A stirring frame 24 is fixedly connected to the output end of the second motor 23, and one end of the stirring frame 24 extends into the treatment box 1. When in use, the sewage treatment agent is poured into the treatment box 1 from the liquid inlet hole, and the second motor 23 is turned on to stir the sewage to accelerate the reaction rate.

As shown in Figure 4, a worm gear 10 is fixedly installed on one side of one end of the rotating plate 5, and a worm 11 is meshed at one end of the worm gear 10. A first motor 12 is fixedly installed on one side of the lower end of the processing box 1, and the output end of the first motor 12 is fixedly connected to the worm 11. T-shaped rods 13 are fixedly installed on both sides of the other end of the rotating plate 5. Guide frames 14 are fixedly installed on both sides of the rotating plate 5 at both sides of the lower end of the processing box 1. The T-shaped rods 13 are inserted into the guide frames 14. T-shaped slots 19 are opened on both sides of the rotating plate 5. Magnets 20 are slidably installed in the T-shaped slots 19, and the magnets 20 are adsorbed on the rotating plate 5. One side of the rotating plate 5 is coated with a polytetrafluoroethylene film 21, and both ends of the polytetrafluoroethylene film 21 extend between the magnets 20 on both sides and the rotating plate 5. When in use, the first motor 12 is turned on to drive the rotating plate 5 to rotate downward, thereby pouring out impurities.

As shown in Figure 4, a lifting rod 15 is hinged at one end of the rotating plate 5, and a U-shaped frame 16 is rotatably installed at one end of the lifting rod 15.

Positioning grooves 18 are provided on the inner walls on both sides of the inside of the processing box 1, and the two ends of the U-shaped frame 16 are clamped in the positioning grooves 18. A clamping groove 22 is provided on one side of the inside of the processing box 1, and one end of the second filter screen 7 is clamped in the clamping groove 22. When in use, the rotating plate 5 drives the lifting rod 15 to move downward, so that the rolling brush 17 cleans the first filter screen 6.

When the utility model is in use, firstly, the sewage to be treated is discharged into the treatment box 1 along the water inlet hole 3, and the sewage flows along the rotating plate 5 to the first filter screen 6, and is filtered by the first filter screen 6. Impurities are filtered out and accumulated on the rotating plate 5, and then the hole plug 9 is opened, and the sewage treatment agent is poured into the treatment box 1 from the liquid inlet hole, and then the second motor 23 is turned on to drive the stirring frame 24 to stir the sewage to accelerate the reaction rate. After a period of reaction, the water valve 25 is opened to collect and use the purified sewage, and then the first motor 12 is turned on to make the first motor 12 rotate forward, the first motor 12 drives the worm 11 to rotate, and the worm 11 drives the worm wheel 10 to rotate, so that the rotating plate 5 rotates, and at this time the T-shaped rod 13 slides along the guide frame 14 to prevent the rotating plate 5 from deviating during the rotation process, and the first motor 12 is turned off after rotating to a suitable position. At this time, the impurities accumulated on the rotating plate 5 will flow to the collection box 2 6, because the surface of the rotating plate 5 is coated with a polytetrafluoroethylene film 21, impurities will not remain on the rotating plate 5, so that the filtered impurities are automatically collected and processed, saving manpower. At this time, the rotating plate 5 drives the lifting rod 15 to move downward, thereby driving the rolling brush 17 in the U-shaped frame 16 to move downward, so as to clean the first filter screen 6. The U-shaped frame 16 slides in the positioning groove 18 to limit the rolling brush 17, and then the second filter screen 7 is taken out of the processing box 1 for cleaning or replacement, so as to prevent impurities from blocking the first filter screen 6 and the second filter screen 7, and improve the filtering effect. After the processing is completed, the first motor 12 is turned on, the first motor 12 is reversed, and the rotating plate 5 is reset. When the polytetrafluoroethylene film 21 needs to be replaced, the magnet 20 is manually moved outward. At this time, the magnet 20 no longer adsorbs the rotating plate 5, so that the polytetrafluoroethylene film 21 can be taken out and then replaced with a new one.
