摘　　要：针对乙二醇生产废水成分复杂,高有机物、高氨氮、高含盐量,处理难度大等特点,采用"微电解—MABR—A/O—高级氧化—混凝沉淀—BAF"组合工艺对其进行中试处理,取得了较佳的处理效果。在进水水质波动较大的情况下,MABR系统仍能达到较好的处理效果,对COD和NH_3-N的去除率分别可达到85%、83%;组合工艺运行稳定,在进水COD和NH_3-N浓度分别为5 000~40 000、450~1 800 mg/L时,最终出水COD≤35 mg/L、NH_3-N≤4 mg/L,主要指标达到了河南省《省辖海河流域水污染物排放标准》(DB 41/777—2013)的要求。Based on the characteristics of wastewater from glycol production, such as complicated composition, high concentrations of organic compounds, ammonia nitrogen and salinity, the combined process of micro-electrolysis, MABR, A/O, advanced oxidation, coagulation and sedimentation as well as BAF was used in pilot-scale treatment. Under the large fluctuation of influent quality, MABR could effectively remove COD and NH3 - N, with the removal rates of 85% and 83%, respectively. The combined process operated stably. When the influent concentrations of COD and NH3 - N were 5 000 to 40 000 mg/L and 450 to 1800 mg/L, the effluent COD and NH3 - N concentrations were less than 35 mg/L and 4 rag/L, respectively. The water quality indexes could meet the Discharge Standard of Water Pollutants in the Haihe River Basin of Henan Province （DB 41/777 -2013）.
