摘　　要：采用UASB—SBR组合工艺处理阿维菌素废水,考察了UASB反应器和SBR反应器中COD的去除效果。UASB反应器稳定运行阶段,当进水COD为9 210 mg/L、容积负荷为9.21 kg/(m3.d)时,COD去除率稳定在85%左右。SBR反应器稳定运行阶段,当进水COD为1 010 mg/L、容积负荷为1.01 kg/(m3.d)时,出水COD在300 mg/L以下,COD去除率约为75%。出水COD达到GB8978—1996《污水综合排放标准》的二级排放标准。The averrnectin wastewater was treated by UASB-SBR process and the COD removal effects of the two reactors were studied. In the stable running stage of the UASB reactor, when the influent COD is 9 210 mg/L and the volume loading is 9.21 kg/（ m3 d）, the COD removal rate is kept at 85%. In the stable running stage of the SBR reactor, when the influent COD is I 010 mg/L and the volume loading is 1.01 kg/（m3 d）, the effluent COD is 300 mg/L with 75% of removal rate, which can meet the second grade discharge standard of GB8978 - 1966.
