摘　　要：针对低温低浊水混凝效果差、絮体小不易沉降等问题,遴选效果较好的助凝剂。将聚合氯化铝与聚丙烯酰胺、海藻酸钠、羟丙基甲基纤维素等助凝剂按比例混合进行混凝搅拌实验,以遴选适合低温低浊水的混凝剂。其中,聚合氯化铝+聚丙烯酰胺+海藻酸按一定比例混合作为混凝剂时,去除色度、浊度效果较好且絮体大,沉降速度较快,结过比选,该组合可作为改善低温低浊水混凝效果的备选药剂。In order to solve the problems such as poor coagulation effect of low temperature and low turbid water and small flocculation,a good coagulant was selected. Coagulating agitation experiments were carried out by mixing poly aluminum chloride with PAC,PAM,sodium alginate,hydroxypropyl methyl cellulose and other coagulants,to select the suitable coagulants for low temperature and low water. When polymerization of aluminum chloride,polyacrylamide and alginate were mixed as coagulants,the effect of chromaticity and turbidity was better,the flocculation was large,and the sedimentation rate was faster. Therefore,coagulant and various coagulants were used to treat low temperature and low turbid water,which can improve the coagulation effect.
