An electric control valve 16 is installed at the bottom end of the hopper 14, and the bottom end of the electric control valve 16 is communicated with the water collecting tank 18. A water extraction pipe 19 is installed on one side of the water collecting tank 18, and the water extraction pipe 19 is fixedly connected with the first pump 8. A water filter plate 17 is installed inside the water collecting tank 18, and one side of the water filter plate 17 corresponds to the bottom end of the sealing door 7. The water filter plate 17 is arranged in an inclined shape;

[0024] A plurality of limiting blocks 13 are arranged on the inner side wall of the treatment bin 10, and the limiting blocks 13 are annularly distributed on the treatment bin 10. A fixed wire frame 20 is arranged at the top end of the limiting block 13, and a fiber ball filter layer 11 is arranged inside the fixed wire frame 20. A filter screen 12 is installed at the top end of the fixed wire frame 20. The filter screen 12 can block large-diameter dirt in the sewage, and the uniform distribution of the fiber ball filter layer 11 can adsorb small-particle dirt in the sewage;

[0025] Specifically, as shown in the figure, during use, the sewage can be statically precipitated inside the treatment bin 10. With the setting of the feeding hopper 14 and the operation of the electric control valve 16, the sediment at the bottom can be discharged into the inside of the water collecting tank 18, and the water filtering plate 17 can filter the sediment, and the excess water liquid leaks into the inside of the water collecting tank 18. By opening the sealing door 7, the sediment can be removed;

[0028] Working principle: When in use, first, move the sewage treatment circulating purification equipment to the target area for placement and connect it to an external power supply. Inject sewage into the interior of the tank body 1 from the interior of the water inlet 3, and inject the corresponding proportion of medicament according to the volume of the sewage. Inject the medicament into the interior of the treatment chamber 10 from the interior of the chemical addition pipe 4. When the sewage enters the interior of the treatment chamber 10, the filter screen 12 can block large-diameter contaminants in the sewage, and the uniform distribution of the fiber ball filter layer 11 can adsorb small-particle contaminants in the sewage, filter the sewage, and enter the interior of the treatment chamber 10 to be mixed with the medicament. Control the operation of the drive motor 5 to drive the stirring frame 9 to rotate, so that the sewage and the medicament are fully mixed together. Then, control the drive motor 5 to stop operating, so that the sewage stands still in the treatment chamber 10. After standing for a period of time, the contaminants in the sewage will precipitate at the bottom. Subsequently, control the electric control valve 16 to open, and discharge the sediment at the bottom into the interior of the water collecting tank 18. The water filtering plate 17 can filter the sediment, and the excess water liquid leaks into the interior of the water collecting tank 18. Open the sealing door 7 to remove the sediment.

Then, control the second pump 15 to operate, which can convey the clear water precipitated in the treatment chamber 10 into the interior of the tubular ultrafiltration membrane module 6. The membrane module inside the tubular ultrafiltration membrane module 6 will deeply filter the water liquid, and finally complete the use of the sewage treatment circulating purification equipment.
