摘　　要：某日用化工企业排放的生产废水表面活性剂浓度较高,针对该类高浓度有机废水,采用气浮-UASB-AO组合工艺进行处理,工程实践表明:当进水COD为6000 mg/L左右的情况下,出水水质达到《污水综合排放标准》(GB 8978-1996)的三级标准要求。The wastewater discharged from daily chemical industry contains a large quantity of organisms, such as surface active agent. It is characterized by complicated components. The combined air flotation-UASB-AO process has been used for its treatment.The practice proves that when the influent COD is about 6000 mg/L, and the system remains relatively stable condition, the effluent water quality meets the requirements for the First Level standard specified in the Integrated Wastewater Discharge Standard(GB 8978—1996).
