An aeration tank 3, a secondary sedimentation tank 4, and a filter tank 5 are formed on the outer surface of the housing 1. Several inlet pipes 6 are fixedly connected to the aeration tank 3 through the housing 1. Several outlet pipes 7 are fixedly connected to the filter tank 5 through the housing 1. The aeration tank 3 and the secondary sedimentation tank 4 are fixedly connected through the primary connecting pipes 8. The secondary sedimentation tank 4 and the filter tank 5 are fixedly connected through the secondary connecting pipes 9. A circulation pipe 10 is fixedly connected to the bottom of the secondary sedimentation tank 4.

The air supply pipe 14 is fixedly connected to the aeration tank 3 through the housing 1. Activated sludge is provided on the outer surface of the aeration tank 3.

[0023] Specifically, by using an air pump 13 to supply air into the aeration tank 3, the activated sludge can microbially degrade the odor of the wastewater after sewage treatment. The activated sludge flows to the secondary sedimentation tank 4 through several No. 1 connecting pipes 8, and then returns to the aeration tank 3 through the circulation pipe 10 to circulate and degrade the odor of the sewage, thereby achieving the effect of removing the odor from the sewage and reducing the odor in the treated sewage.
