摘　　要：通过3种混凝剂和添加助凝剂的对比实验．找出适合的混凝剂和投加量，然后采用混凝过滤的方法处理校园洗涤废水。实验结果表明，在去除浊度、COD和投加量方面，复合高效聚合氯化铝（净水灵）比聚合硫酸铁（PFS）和聚合氯化铝（PAC）用量少、去除率高。投加助凝剂聚丙烯酰胺（PAM）效果不明显。不添加助凝剂，净水灵投加量40mg／L，滤速7．5—10m／h，浊度去除率可以达到90％，COD去除率在80％左右，出水水质达到回用水要求。By comparing three kinds of coagulants and coagulant aids, the suitable coagulant and dosage is selected. The cmntms washing wastewater is treated by the process of coegulation and filtration of no settling. The results indicate： in aspects of turbidity, COD and dosage, performance of compoite high PAC is better than that of PAC and PFS and the effect of coagulant aid of PAM is not obvious. When without adding coagulant aid, 40 mg/L dosage of compte high PAC and 7.5 m/h -10 m/h of filtration velocity, the removal of turbidity and GOD can reach 90% and about g0% respectively and the water quality can meet reuse standard.
