摘　　要：以硫酸亚铁、硫酸镁和聚二甲基二烯丙基氯化铵(PDMDAAC)为原料,制备了一种新型无机-有机复合絮凝剂PFMS-PDMDAAC,应用于垃圾渗滤液的处理。实验结果表明,PFMS-PDMDAAC对于垃圾渗滤液的絮凝效果良好,PFMS-PDMDAAC复合絮凝剂的絮凝效果不仅优于PFMS,而且优于PFMS+PDMDAAC投加方式,两者复配呈现出显著的协同作用,絮凝效果明显提高。A novel inorganic-organic composite floeculant,PFMS-PDMDAAC,has been synthesized by using FeSO4, MgSO4 and polydimethyl diallyl ammonium chloride （PDMDAAC） as raw materials and has been applied to the treatment of landfill leachate. The coagulation results indicate that PFMS-PDMDAAC has good coagulative effect on the treatment of landfill leachate. Its composite coagulative effect is not only better than that of PFMS, but also better than the kind of adding form of PFMS＋PDMDAAC. When treating the landfill leachate the coagulation efficiency of PFMS-PDMDAAC is higher than that of PFMS and that of PFMS＋PDMDAAC. The composite of PFMS-PDMDAAC plays a synergistic effect of PFMS and PDMDAAC and the coagulation efficiency has been heightened after complex formulation.
