摘要
洗车废水含有油污,泥沙,表面活性剂及其他可溶性有机物。洗车废水处理回用技术因洗车规模大小不同存在很大差别。该文介绍了目前国内外大型洗车场废水处理回用的主要工艺,概括和比较了洗车点洗车废水回用装置的主要技术,分析了目前小型回用装置存在的问题,并对发展方向作了展望。
Wastewater originating from vehicle washing contains a number of impurities such as free oil, oil/wateremulsion, clay sludge, surfactant and other soluble organic matters. The technologies used in treating and recyclingwastewater are different for the different scale of the vehicle washing sites. In this article, the major treatment processes inla,ge scale vehicle washing sites at home and abroad were introduced and the major methods adopted in recyclingapparatus which are used in small washing sites were presented. Different treating methods were compared, and the problemsexisting and the prospect of the recycling of the washing water were analyzed subsepuently.
