摘　　要：洗涤废水成分复杂,COD及氮、磷浓度较高,排入水体后易造成水体富营养化。采用好氧接触氧化+混凝沉淀+人工湿地处理洗涤废水,实际运行结果表明,该工艺对洗涤废水的处理效果十分显著,COD平均去除率达到87. 67%,TP平均去除率达到93. 62%,NH_3-N平均去除率达到85%,各项指标均满足《污水综合排放标准》(GB 8978—1996)的一级标准。Washing wastewater,characterized by high COD,nitrogen,and phosphorus,is likely to cause eutrophication when directly discharges into water body.A process consisting of aerobic contact oxidation,coagulation precipitation and artificial wetland was used to treat washing wastewater.The practical operation results showed that the treatment effect of the process was significant.The average removal of COD,TP and NH3-N reached 87.67%,93.62%and 85%respectively.All effluent quality indicators could meet first level criteria specified in the Integrated Wastewater Discharge Standard(GB8978-1996).
