| 摘 要： | 为解决洗车废水回用问题,采用混凝沉淀方法去除洗车废水中的泥砂、有机物及洗涤剂类污染物质,去除率均在40%以上.未被去除的溶解性小颗粒物质则可通过砂滤、活性炭吸附、膜过滤进行去除,从而使出水浊度满足在5 NTU以下.其中超滤对浊度的去除率接近于100%,活性炭对阴离子洗涤剂的去除率在70%以上,同时活性炭对有机物也有很好的去除效果.试验结果表明:出水完全满足我国生活杂用水水质标准对洗车废水回用水质的要求.

| Abstract: | There are mud, sand, organic substances and detergent in car wash wastewater. Coagulation and sedimentation are adopted to remove the three kinds of pollutants. The removal rate is up to 40% . Remanent matters can be removed by sand filtration, active carbon filtration and membrane filtration. As a former process, sand filtration can remove most turbidity and some of organic matters. Most anionic detergents are removed by active carbon absorption. Up to 100% turbidities is removed by ultrafiltration to satisfy the water quality criteria of Peoples' Republic of China. |
