摘要
以珠海市洗车废水为样本,以浊度、色度、化学需氧量(COD)和阴离子表面活性剂(LAS)为污染指标,选用硫酸铝(Al_2(SO_4)_3)、聚合硫酸铁(PFS)、聚合氯化铝铁(PAFC)为试验混凝剂。最终确定洗车废水的最佳混凝剂为PAFC,其最佳投加量为450 mg/L,对COD、LAS、浊度、色度去除率分别为64.55%,63.27%,98.75%,97%。
Taking Zhuhai City as a sample of car washing wastewater,turbidity,color,chemical oxygen demand（COD） and anionic surfactant（LAS） were used as indicators of pollution.The aluminum sulfate（Al2（SO4）3）,polyferric sulfate（PFS） and polyaluminum ferric chloride（PAFC） were used as the test coagulant.The optimum coagulant for car washing wastewater was PAFC,the optimum dosage was 450 mg/L,COD,LAS,turbidity and color removal rate were 64.55%,63.27%,98.75%,97%,respectively.
