The expansion box 2 is connected to the aeration tank 1. The top of the expansion box 2 is provided with a sewage inlet pipe. After the sewage enters the expansion box 2, it will first fall on the screen 21. The screen 21 separates larger impurities. The sewage passing through the screen 21 will enter the aeration tank 1 for aeration operation. A driving mechanism is provided on the other side of the expansion box 2 for driving the drum 8 to rotate. The impurities intercepted by the screen 21 will be transported out of the expansion box 2 and discharged to the outside. A drain port is provided on the inner wall of the aeration tank 1, and the aerated sewage is discharged into subsequent equipment from the drain port.

[0025] In this embodiment, a driving wheel 9 is provided on one side of the lower surface of the rotating plate 3, and the driving motor 5 is connected to the driving wheel 9 through a gear. A driving ring 10 is provided on the top of the aeration tank 1, and a rack 11 is provided on the outer circumference of the driving ring 10. The driving wheel 9 and the rack 11 are meshed.
