针对畜禽养殖污染废水传统处理方法效率不高、噪声较大等缺点进行改进,采用＂水解酸化池-塔式膜生物反应器-悬浮澄清池＂工艺进行处理,结果表明：COD、氨氮去除率分别为97.5%和91%,出水水质可达GB 18596—2001《畜禽养殖污染物排放标准》。“,”According to the defects of the traditional methods, such as low efficiency and high noise etc, “hydrolytic acidification-tower biofilm reactor-：suspended clarification” technique was used to treat livestock wastewater in this experiment. The result showed that the removal efficiency of the COD and NH3-N was 97.5% and 91% respectively. The effluent quality could meet the requirements of “Discharge Standard of Pollutants for Livestock and Poultry Breeding” （GB 18596--2001 ）.
