The ammonia-containing tail gas treatment device comprises a treatment tank, supporting rods are fixedly connected to the two ends of the bottom of the inner wall of the treatment tank, an annular pipe is fixedly connected between the tops of the two supporting rods, gas outlet pipes are fixedly connected to the top of the annular pipe at equal intervals, and one-way valves are arranged in the gas outlet pipes. A suction fan is fixedly installed on one side of the bottom of the treatment tank, and the output end of the suction fan extends into the treatment tank and is fixedly connected with one end of the annular pipe. The ammonia-containing tail gas treatment device has the advantages that ammonia-containing tail gas is uniformly introduced into the treatment tank by the aid of the annular pipe and is buffered and decelerated by the aid of the blades, accordingly, the ammonia-containing tail gas can stay in the treatment tank for a longer time, treatment effects can be further improved by spraying the ammon
