摘　　要：用自制聚铁和硅酸钠制备的聚硅酸氯化铁处理模拟水样。考察了絮凝剂的加入量、处理水样的pH值、搅拌速度和搅拌时间等对絮凝效果的影响,同时对自制絮凝剂与市售聚铁铝絮凝剂对海水的絮凝效果做了比较。结果表明:该絮凝剂在加入量为42mg/L、快搅速度为240r/min、慢搅时间为16min、静置30min、酸碱度为中性或略碱性时絮凝效果较好。对海水的探索性实验中,自制絮凝剂优于其它几种。The coagulant PFSC, prepared with polyferric chloride （PFC） and sodium silicate, was used to treat the simulate wastewater. Test about the content, different pH value of water, the mix rate and time were made. Experimental results showed that the PFSC had better coagulation properties when the content was 42mg/L, the fast mix rate was 240r/min, the slow mix time was 16min and the value of pH was about 7. Also, the performance of PFSC was better than PFC, FC, PASC on the floc shape and performance ,the ability of turbidity removal to the seawater.
