摘　　要：以价廉的铝酸钙粉为原料,研制了一种用于市政废水除磷的高效低耗的聚合氯化铝铁(PAFC)无机高分子复合絮凝剂。研究内容包括:PAFC的制备方法研究,PAFC用量对模拟废水和实际废水除磷、除浊效果的影响,废水经PAFC处理后pH值的变化情况,废水酸度对除磷效果的影响,PAFC与常见商品絮凝剂除磷性能的比较研究。试验结果表明:自制的铝铁复合絮凝剂的除磷效果好于传统的铁盐和商品铝铁盐;除浊效果也较好,除浊率可达到95%以上;废水处理后pH值也较稳定。PAFC用于市政废水有较优异的除磷、除浊性能。Polyaluminum ferric chloride （PAFC）, an inorganic polymer compound flocculant with high efficiency and energy saving for phosphorus removal in municipal wastewater treatment, was prepared with cheap calcium aluminate powder, and some researches on the methods for PAFC preparation, the effect of PAFC dosage on phosporus removal in the simulating and practical wastewater were done,and turbidity removal effect was better than that of traditional iron salt and commercial PAFC; turbidity removal rate could reach to over 95%; after treating, pH was more stable; the PAFC had excellent performance of phosphorus and turbidity removal for municipal wastewater treatment.
