摘　　要：对富磷污水进行混凝除磷研究,以出水总磷为评价指标,对硫酸铝、氯化铝、硫酸铁、碱式硫酸铁混凝剂进行比较实验。实验表明新型碱式硫酸铁为适合处理富磷污水的混凝剂,且碱式硫酸铁用于处理富磷污水时,去除等量总磷所消耗的药剂更少,利用率更高。Experimental study on dephosphorization of phosphorus-rich sewage by coagulation is conducted in this paper.Comparative experiment of Al2（SO4）3,AlCl3,Fe2（SO4）3,and [Fe（OH）SO4]n is conducted with total phosphorus of the effluent as the evaluation indicator.The results indicate that [Fe（OH）SO4]n is the fittest coagulant to phosphorus-rich sewage.When [Fe（OH）SO4]n is used to dispose phosphorus-rich sewage,reagent consumption per unit weight of total phosphorus is less and the utilization ratio is higher.
