When treating sewage, the sewage to be treated can be first poured into the water inlet 6 at the top of the mixing tank body 1, and the sewage can be introduced into the filter screen 9 inside the mixing tank body 1 through the water inlet 6. The sewage can be filtered for the first time through the filter screen 9 inside the mixing tank body 1. Under the action of the filter screen 9, large particles of impurities in the sewage can be filtered to prevent large particles of impurities from affecting the sewage treatment effect. After the sewage passes through the filter screen 9, the drive motor 7 can be turned on to make the motor drive shaft 8 rotate, and then the motor drive shaft 8 can be driven to drive the sewage. The movable scraper 10 rotates in close contact with the filter screen 9, and the impurities on the filter screen 9 are scraped into the collection box 11 by the scraper 10 to avoid clogging of the filter screen 9 during long-term use. After the sewage passes through the filter screen 9, it will fall into the bottom end of the mixing tank body 1. At this time, since the motor drive shaft 8 is rotating, the stirring rod 13 at the bottom will be driven to rotate synchronously. At this time, the sewage evolution agent is poured into the mixing tank body 1, and then the stirring rod 13 is stirred to make the sewage evolution agent and the sewage in the mixing tank body 1 uniformly mixed and reacted. When the rod 13 rotates, it will also drive the first cleaning plate 14 to rotate along the inner wall of the mixing tank body 1. The impurities attached to the inner wall of the mixing tank body 1 will be scraped off by the first cleaning plate 14 to prevent a large amount of impurities in the sewage from adhering to the inner wall of the mixing tank body 1, making it difficult to clean. At the same time, the second cleaning plate 15 at the bottom will also rotate along the inner wall of the bottom end of the mixing tank body 1 to clean the impurities at the bottom end of the mixing tank body 1. When the internal sewage treatment is completed, the internal sewage can be discharged through the outlet pipe 16 by opening the outlet valve 17.
