The odor generated by decomposing organic matters in the anaerobic tank and the tail gas generated by the aerobic tank are exhausted by the fan and enter the biological filter tank through the exhaust pipe to be purified, so that the direct emission of harmful gases is reduced, and the pollution to the environment is reduced.

Further the biological filter box is respectively a spraying water distribution layer, a packing bracket, an air distribution layer and a backflow water collecting tank from top to bottom, spray nozzles are distributed on the spraying water distribution layer, the backflow water collecting tank is connected with the spray nozzles through a water pump in a pumping mode, and the outlet end of the exhaust pipe is connected with the air distribution layer. The backflow collecting tank is internally filled with a solution for purifying the tail gas, the solution is pumped to a spray head through a water pump, then is sprayed downwards to a packing layer, then falls to a gas distribution layer, and finally flows back to the backflow collecting tank, the tail gas is uniformly distributed from an exhaust pipe to the gas distribution layer, then rises, and is discharged after the packing layer and the falling solution are sufficiently decomposed and purified.

Further the biological filter box front portion is equipped with the spray column, the blast pipe links to each other with the spray column bottom, and the spray column top is equipped with the gas vent, the gas vent passes through the pipeline and is connected with the gas distribution layer in the biological filter box. The spray tower uses water as an absorbent to humidify and remove dust from the tail gas and absorb water-soluble waste gas such as ammonia and the like, and then the water-soluble waste gas is further deodorized and purified through the biological filter box, so that the purification effect is improved.

Further, a stirring device is arranged in the anaerobic tank. Stirring is carried out in the anaerobic tank to push the suspended filler in the anaerobic tank to move, and the device has better effect of decomposing organic matters.

And a check valve is arranged on the exhaust pipe communicated with the anaerobic tank. The tail gas with oxygen in the aerobic box is prevented from entering the anaerobic box to influence the propagation of anaerobic microorganisms and the decomposition of organic matters.

To sum up, the utility model provides a reduce ammonia nitrogen tail gas's emission, reduce the environment-friendly filtration liquid treatment facility to the pollution of environment.
