摘要
介绍三级沉淀池(物化预处理)+三级过滤罐(粗滤-细滤-微滤)多级过滤工艺处理洗车废水的回用应用效果。结果表明:出水水质的13项指标已达到《城市污水再生利用城市杂用水水质》(GB/T 18920—2002)车辆冲洗标准,且总大肠菌群、LAS、BOD_5、色度、浊度等5项指标的去除效果较为明显,去除率分别达到了100%、98.82%、95.71%、88.10%、93.15%以上。
Reuse application with three level sedimentation tank （ physicochemical pretreatment） ＋ three level filtration tank （ coarse filter-fine filtration-microfiltration） multistage filtration process of car washing wastewater treatment is introduced reuse application. The results show that the removal effects of total coliform group, LAS, BODs, ehroma, turbidity and other 5 indicators are obvious. Removal ratio reaches to 100%, 98.82%, 95.71%, 88.10%, 93.15%, and the effluent quality has reached to or has been higher than the standard of Municipal Wastewater Reclamation And Reuse Urban Miscellaneous Water Quality（ GB/T 18920 2002）.
