The aeration tank can have multiple structures, preferably, the aeration tank has the cell body and sets up the drainage cover on the cell body, and the third water inlet is located the top of cell body, and it is sealed with the top of cell body that the drainage cover link up from top to bottom and its outer wall, and in this drainage cover's bottom stretched into the cell body, the bottom top-down of drainage cover was the loudspeaker form that inside wall size is crescent gradually, and the third delivery port is located the top of drainage cover, and the top of packing layer is stretched out at the top of drainage cover. Through setting up the drainage cover, be favorable to rivers to get into the packing layer top from the cell body.

In order to facilitate the wastewater to enter the drainage cover and simultaneously not interfere the process of the wastewater flowing into the pool body, the size of the outer wall of the bottom of the drainage cover is smaller than the size of the inner side wall of the corresponding position of the pool body. Like this, have the interval between the outer wall of drainage cover and the inner wall of cell body, be favorable to waste water to get into the cell body through this interval.

In order to prevent the filler from entering the filler layer through the drainage pipeline, a filter screen is arranged in the drainage cover and used for preventing the filler in the tank from upwards entering the filler layer.

Compared with the prior art, the utility model has the advantages that: through setting up aeration system and anaerobic treatment district in the device main part, have the interval and form the second delivery port in anaerobic treatment district between the inside wall of the top of the outer wall of aeration tank and device main part, waste water from the top gets into behind the anaerobic treatment district, from the bottom and reach the top of aeration tank down after that, again from the bottom and get into inside the aeration tank down, first water inlet like this, anaerobic treatment district, the vertical intercommunication that goes up of aeration tank, thereby area is little, the waste water route is longer and can improve water treatment effect.
