摘　　要：主要研究了有机高分子絮凝剂阴离子聚丙烯酰胺(PAM)和聚合氯化铝(PAC)对净水厂排泥池水絮凝沉淀效果和污泥浓缩池污泥浓缩效果的影响。研究表明,投加阴离子PAM可提高和加快污泥浓缩池污泥浓缩速度;投加PAC不能改善排泥池水絮凝沉淀效果。与单独投加PAM相比,PAM和PAC联合投加可以取得更好的絮凝沉淀效果。In this paper,the effects of organic polymer flocculants anionic polyacrylamide(PAM)and polyaluminium chloride(PAC)on the flocculation and sedimentation effect of water in sludge discharge pond and sludge thickening effect in sludge thickening pond of water purification plant were studied.The research shows that adding anionic PAM can improve and speed up the sludge concentration rate in sludge concentration tank,but adding PAC can’t improve the flocculation and sedimentation effect of sludge discharge tank water.Compared with PAM alone,the combination of PAM and PAC can achieve better flocculation and sedimentation effect.
