[0039] Air enters the aeration pipe 2205 through the air outlet pipe 7, and is sprayed into the sewage in the purification box 1 through a plurality of groups of air nozzles 2206, thereby increasing the oxygen content in the sewage and prompting the microbial community 24 to purify the sewage. The third gear 2203 is driven to rotate by the second motor 2201, so that the outer gear ring 2204 drives the second rotating joint 2202 to rotate, thereby causing the aeration pipe 2205 to rotate synchronously, allowing air to enter different positions of the sewage and promoting the flow of sewage at the same time, so that the sewage and the microbial community 24 are in more thorough contact, thereby improving the sewage purification efficiency.
