摘　　要：采用模拟试验方法研究PACF、eCl3和Al2(SO4)3混凝剂对马铃薯淀粉废水的混凝预处理效果。通过对废水处理前后各项指标及处理成本等各方面因素进行综合分析,结果得知,Al2(SO4)3作为马铃薯淀粉废水的混凝剂较为合适,此时Al2(SO4)3的最佳投药量为500mg/L,对废水的COD去除率可达到34%左右。The paper mainly discussed the PAC, FeCl3 and M2 （SO4 ）3 coagulant effect on the potato starch wastewater. Al1 of the indexes of the wastewater before and after the treatment, and the costs were analyzed synthetically. The results showed that M2（SO4）3 was the suitable coagulant to concrete the potato starch wastewater. On condition that the optimum dosage of M2（SO4）3 was 500 mg/L, the COD removal rate achieved 34%.
