摘　　要：以超滤为核心工艺处理洗车废水,对比了采用混凝沉淀-砂滤和单独采用砂滤作为预处理时的出水指标,两种工艺对浊度的去除率分别为99.4%和99.1%,对COD的去除率为69.5%和53.4%,对阴离子表面活性剂(Anionic surfactant,AS)的去除率为69.2%和27.6%。结果表明,采用适合的预处理单元,以超滤为核心的处理工艺在洗车废水循环回用方面具有可行性。As pretreatment processes, coagulation and sedimentation-sand filtration and single sand filtration were compared by using uhrafiltration as key treatment process of car washing wastewater. Removal rates of turbidity from both processes were 99.4 % and 99.1%. Removal rates of COD were 69,5 % and 53.4 %. Removal rates of anionic surfactant were 69.2 % and 27.6 %. The resuits showed that the recycling method of car washing wastewater based on uhrafiltration technology was feasible under the condition of reasonable pretreatment processes.
