Combined with the aeration holes on the stirring rod assembly, it not only provides aeration and oxygen for biological reactions, but also blows the suspended filter media through the aeration holes, thereby accelerating the floating of the suspended filter media in the suspended packing zone. The faster floating speed of the suspended filter media not only ensures full contact between the suspended filter media and the sewage, improving the water treatment effect, but also increases the speed at which water flows through the suspended filter media, thereby reducing clogging. At the same time, the suspended filter media are more likely to collide with each other, causing the blockage to detach after the collision, further reducing the clogging of the suspended filter media.

[0017] 2. This utility model is designed as an integrated tower structure. Through reasonable design, it combines biological and physical methods to improve the sewage treatment effect, while saving space and being practical. Attached Figure Description
