摘　　要：采用混凝/ABR填料反应器/推流曝气工艺处理针织印染废水,处理规模为8 400m3/d。运行结果表明此工艺能有效去除废水中的污染物,出水平均COD、BOD5、SS、色度、S2-浓度分别为65 mg/L、15 mg/L、13 mg/L、31倍、0.1 mg/L,出水水质达到广东省《水污染物排放限值》(DB 44/26—2001)第Ⅱ时段一级排放标准,直接运行费<0.9元/m3。Coagulation/anaerobic baffled reactor （ABR）/plug-flow aeration process was used for treatment of knitting printing and dyeing wastewater with a capacity of 8 400 m^3/d. The results show that this combined process has high treatment efficiency of pollutants. The average effluent concentrations of COD, BOD5 , SS, color and S2- are 65 mg/L, 15 mg/L, 13 mg/L, 31 times and 0.1 mg/L respectively. The effluent quality meets the first class criteria （ the second period） of the Guangdong Province local standard Discharge Limits of Water Pollutants （DB 44/26 -2001 ）. The direct operation cost is less than 0.9 yuan/m^3.
