摘　　要：针对某化工废水高CODcr水质特点选定3种混凝剂:PAC、Al2(SO4)3与PFS。首先分别确定两种药剂的最佳用量,然后找出各自最适宜的pH值,通过实验结果对比,选定了PAC,该混凝剂处理废水后CODcr为349 7mg/L,去除率达到66 7%。Three kinds of coagulants including PAC, Al2(SO4)3 and PFS are chosen to treat wastewater from chemical industry with high concentration of COD. First of all, the optimal use levels of two kinds of coagulants are tested, then the suitable pH value is decided. PAC is the most suitable coagulant through comparing the results. The concentration of CODcr of the wastewater been treated by PAC is 349.7mg/l, and the removal rate of CODcr reaches 66.7%.
