摘　　要：实验研究了在不同磷浓度下铁盐、聚丙烯酰胺(PAM)和钢渣三者联合处理水中磷的方法。探索了在不同磷浓度下铁盐、聚丙烯酰胺(PAM)和钢渣三者联合容积絮凝处理水中磷的最佳投药量。在综合考虑各种情况下,原水磷浓度为8 mg/L时,三者联合容积絮凝最佳投加量为n(Fe)∶n(P)=2.5,PAM投加量为0.1 mg/L,钢渣投加量为4 g/L;原水磷浓度为4 mg/L时,三者联合容积絮凝最佳投加量为n(Fe)∶n(P)=3.5,PAM投加量为0.05 mg/L,钢渣投加量为3 g/L;原水磷浓度为2 mg/L时,三者联合容积絮凝最佳投加量为n(Fe)∶n(P)=2.5,PAM投加量为0.1 mg/L,钢渣投加量为3 g/L。最佳投药量下的出水磷浓度均满足《地表水环境质量标准》(GB3838-2002)Ⅲ标准。The combined treatment of phosphorus in water with iron salts,polyacrylamide(PAM) and steel slag at different phosphorus concentrations was studied.The optimal dosage of phosphorus in water treated by combined volume flocculation of iron salt,polyacrylamide(PAM) and steel slag at different phosphorus concentrations was investigated.Under various conditions,when the concentration of phosphorus in raw water is 8mg/L,the optimal dosage of the three combined volume flocculation is n(Fe):n(P)=2.5;the dosage of PAM is 0.1mg/L,and the dosage of steel slag is 4g/L.When the concentration of phosphorus in raw water is 4mg/L,the optimal dosage of the combined volume flocculation is n(Fe):n(P)=3.5;the dosage of PAM is 0.05mg/L,and the dosage of steel slag is 3g/L.When the concentration of phosphorus in raw water is 2mg/L,the optimal dosage of the combined volume flocculation of the three is n(Fe):n(P)=2.5;the dosage of PAM is 0.1mg/L,and the dosage of steel slag is 3g/L.The effluent phosphorus concentration under the optimal dosage met the Ⅲ standard of Surface Water Environmental Quality Standard(GB3838-2002).
