摘　　要：采用隔油/气浮/澄清/活性炭过滤联合处理工艺能有效去除含油洗车废水中主要污染物(油类和煤粉),实际运行结果表明,该组合工艺对洗车废水中COD、石油类、悬浮物的平均去除率分别为99.32%、99.87%、89.13%,出水平均COD<40 mg/L,石油类<5 mg/L,SS<15 mg/L,出水水质远优于《煤炭工业污染物排放标准》(GB 20426—2006)排放限值要求。The combined process of oil separation, air floatation, clarification and activated carbon filtration can effectively remove oils and pulverized coal from mine car wash wastewater. The practical running results showed that the average removal rates of COD, oils and SS were 99.32%, 99.87% and 89.13 % respectively, and the average concentrations of COD, oils and SS in the effluent were less than 40 mg/L, 5 mg/L and 15 mg/L respectively. The effluent quality met the emission limits of Emission Standard for Pollutants from Coal Industry （ GB 20426 - 2006 ）.
