摘　　要：通过某钢铁公司废水处理研究试验,采用不同混凝剂和阴阳离子型聚丙烯酰胺(PAM)助凝剂,对不同时间段的废水进行混凝试验,确定最佳加药量和最佳混凝剂。试验表明,硫酸铝对油、全铁和COD等的去除率相对较高,且具有不需投加助凝剂PAM、适用性强等优点。A pilot-scale experiment was made to treat wastewater from steel works by coagulation. Various coagulants and PAM were used to treat wastewater in order to determine the optimum coagulant and dosage, and results indicated that aluminium sulphate obviously enhanced the removal of oil, full iron and COD especially without adding PAM.
