摘　　要：本研究选择校园污水作为实验对象,探讨了以聚合硫酸铁(PFS)辅以阴离子型聚丙烯酰胺(PAM)作为助凝剂,对污水进行混凝-絮凝处理,考察其除磷效果及其影响因素,确定最佳投药量。实验结果显示在三种不同磷浓度下单独投加聚合硫酸铁(PFS)和聚合硫酸铁与聚丙烯酰胺(PFS+PAM)联合使用在一定程度上提高了除磷效果,并确定最佳投药量,若为单独投加PFS,则最佳投药比为n(Fe)∶n(P)=5.5;若为PFS和PAM两者联合投加,则最佳投药量为n(Fe)∶n(P)=3下联合投加使用。Taking campus wastewater as the object of study,coagulation-flocculation treatment of wastewater was carried out using polymerized ferric sulfate(PFS)supplemented with anionic polyacrylamide(PAM)as coagulant to investigate the phosphorus removal effect and its influencing factors,and to determine the optimum dosage.The results obtained proved that the conditions for three different phosphorus concentrations of PFS alone and PFS+PAM jointly,to determine the optimal dosage,if the PFS alone,the optimal dosage ratio isn(Fe)∶n(P)=5.5;If the PFS and PAM are jointly dosed,the optimal dosage of n(Fe)∶n(P)=3 under the joint dosage used.
