摘　　要：以钢铁盐酸酸洗废液和氯化铝为原料,首次制备了系列聚合氯化铝亚铁混凝剂——CPAF(Fe2+)。高岭土模拟水样混凝试验结果表明:n(Al3+):n(Fe2+)=9:1,碱化度=2.0的CPAF(Fe2+)性能最佳。应用于造纸废水的最佳投加量为2.0mmol·L-1,浊度、色度、COD最佳去除率分别为93.09%,78.57%和51.65%。Taking waste liquor from steel-cleaning in hydrochloric acid and aluminum chloride as raw materials,a series of polymerization aluminum-ferrous chloride coagulants were prepared at first.e result of coagulation tests were performed by using synthetic suspension containing kaolinite indicated that when molar ratio of Al 3＋ and Fe 2＋ of 9：1,basicity of 2.0,the property of the products was the best.e best removal rations of turbidity,chromaticity and COD to the papermaking wastewater were 93.09%,78.57%,51.65%under the optimal dosage of 2.0mmol·L-1.
