摘　　要：大多城市洗车水未经过任何处理就直接排放到城市的污水管网中,加剧了城市供水的紧张状况和环境污染.经分析认定城市洗车水多项指标超标后,进行了单因素和放大实验研究,得出了处理冲洗水的工艺线路和数据.经过处理后水的主要指标为:阴离于洗涤剂含量下降到0 008mg·L-1,悬浮性固体0 2mg·L-1,BOD5、CODCr也远远低于国家生活杂用水指标,可以回用.　Most car washing water in the cities,without being treated and recycled,is directly charged into the sewage network.This situation makes water supply more short and environmental pollution more serious.After analyzing the components of wastewater, the author found the main targets of it beyond the standards.and made a series of experiments and pilot studies in lab, and then obtained the process and data in treating wastewater. Through this process,the quantities of anion wash reach 0.008 mg·L^(-1), SS to 0.2 mg. L^(-1) and BOD_5, COD_(Cr) are mostly lower than the national　standard for miscellaneous.The treated water can be reused.
