摘　　要：针对某污水厂的污泥水上清液,采用盐基度不同的聚合氯化铝(PAC)进行除磷小试。结果表明,在n(Al)∶n(P)相同的情况下,低盐基度的PAC对磷的去除效果要优于高盐基度的PAC。要使出水TP小于0.1 mg/L,使用低盐基度和高盐基度PAC时对应的n(Al)∶n(P)分别为3.7和6.1。达到相同的除磷效果,使用低盐基度PAC可以减少用量,降低生产成本。For the supernatant of sludge water of a wastewater treatment plant,the polyaluminium chloride(PAC)with different basicity was used for phosphorus removal.The results showed that when n(Al)∶n(P)was the same,the phosphorus removal effect of PAC with low basicity was better than that of PAC with high basicity.In order to make the effluent TP less than 0.1 mg/L,the corresponding n(Al)∶n(P)were 3.7 and 6.1 respectively when PACs with low and high basicity was used.To achieve the same phosphorus removal effect,the use of low basicity PAC could reduce both the dosage and the production cost.
