After the device is placed stably, the wastewater to be treated is injected into the interior of the treatment tank 1 through the water inlet pipe 3, and the valve 31 is closed and the first pipe cap is tightened before water inlet. Then, the wastewater enters the interior of the filter tank 12 through the water inlet pipe 3 and the through hole, and the filter assembly inside the filter tank 12 filters the wastewater. Then, the filtered wastewater enters the interior of the reaction tank 7 through the through slot 11 for precipitation. During precipitation, the second pipe cap is rotated to open the feed pipe 9 to add the reagent required for precipitation into the interior of the reaction tank 7, and the stirring assembly is used to make the reagent and the wastewater react fully, so that the precipitation effect is better. After the precipitation, the precipitate can be discharged by rotating and opening the second pipe cap after the wastewater is discharged.

During operation, the rotating plate 15 is rotatably connected between the two inner grooves 16 through the torsion spring 40 and the third rotating rod 39 and penetrates through the filtering tank 12. Then, the filter screen 18 inside the rotating plate 15 corresponds to the filtering tank 12, and the waste water injected into the filtering tank 12 inside the treatment tank 1 can be filtered through the filter screen 18. Then, through the torsion spring 40 and the third rotating rod 39, the rotating plate 15 and the filter screen 18 can play a certain buffering role when filtering the falling waste water, and the service life of the filter screen 18 can be extended. At the same time, the rotating plate 15 is arranged in an inclined shape, so that some of the filtered impurities can be concentrated on the left side of the filter screen 18 along the inclined surface of the filter screen 18, and the influence of the impurities on the subsequent filtering of the filter screen 18 can be reduced. Then, after the filtering is completed or during the process of the waste water falling for filtering, since the rotating plate 15 can rotate to a certain extent through the third rotating rod 39, and the third rotating rod 39 can be reset through the restoring force of the torsion spring 40, the rotating plate 15 and the filter screen 18 can vibrate up and down to a certain extent during the filtering process, and the impurities filtered on the surface of the filter screen 18 can move and concentrate better to the left, thereby avoiding frequent cleaning of the middle part of the filter screen 18 for filtering and making the device have a better use effect.

[0023] As a preferred embodiment of the present invention, a through slot 13 is provided between the left sides inside the two inner slots 16.

The bottom of the rotating plate 15 is in contact with the top of the rubber pad 19. A handle is fixedly connected to the center of the left side of the collection box 14. During operation, the left side of the rotating plate 15 is inside the collection box 14, so the impurities falling along the rotating plate 15 to the left can be collected by the collection box 14. And the collection box 14 is fixedly installed on the processing box 1 through the mounting bolt 2, so that the mounting bolt 2 can be rotated to disassemble and clean the collection box 14, and the influence of the long-term non-treatment of the collection box 14 on the subsequent collection effect can be avoided. At the same time, the rubber pad 19 arranged between the bottom left side of the rotating plate 15 and the inside of the collection box 14 can increase the buffering effect of the rotation and downward inclination of the rotating plate 15, and can also make the fit between the rotating plate 15 and the collection box 14 closer through the rubber pad 19, and make the falling impurities better enter the collection box 14.

[0024] As a preferred embodiment of the present invention, a support block 17 is fixedly connected inside the inner slot 16.

The guide rod 20 is slidably connected to the cleaning brush 21. During operation, the rotation of the threaded rod 37 is driven by the energization of the first motor 4, and the rotation of the threaded rod 37 drives the cleaning brush 21 to move under the penetration and guidance of the guide rod 20. Then the cleaning brush 21 can clean the surface of the filter screen 18 when it moves. And when the cleaning brush 21 moves the impurities and the like to the left side of the rotating plate 15, it is convenient to take out and process the cleaned impurities and the like through the slot 13. Thus, it is not necessary to disassemble and clean the filter screen 18, and the failure rate and maintenance cost of the device are avoided, and the device is convenient to use. At the same time, the motor can rotate forward and backward, so that the cleaning brush 21 can return to its original position after cleaning for the next cleaning, or the cleaning brush 21 can be used for back-and-forth cleaning.

And when the slider 43 disengages from the extrusion of the fixed block 42, the rotating plate 15 and the filter screen 18 will reset under the action of the torsion spring 40 and the third rotating rod 39. Therefore, during the cleaning process of the cleaning brush 21, the rotating plate 15 and the filter screen 18 will vibrate, and the impurities that are convenient to clean will fall along the inclined filter screen 18, making the cleaning effect of the filter screen 18 better.
