摘要
以不同碱化度 (B)的聚合氯化铝 (PAC)和二甲基二烯丙基氯化铵均聚物(PDMDAAC)制备聚合氯化铝 二甲基二烯丙基氯化铵均聚物复合混凝剂 (PAC PDMDAAC) ,试验了其处理模拟水的除浊效果及水体的残余铝量 .结果表明 :PAC PDMDAAC较PAC具有更低的投加量 ,更好的除浊效果 ,处理后水体具有更低的残余铝量 .B和PDMDAAC质量百分含量 (P % )对PAC
Composite flocculants of polyaluminum(PAC)-ploydimethyldiallylammonium chloride(PDMDAAC)was prepared by using PAC with different basicity(B)and PDMDAAC as raw materials.And the flocculating efficiency of PAC-PDMDAAC treating simulating water was preliminary examined by Jar-test.The experimental results show that the PAC-PDMDAAC is characterized by lower dosage and better coagulation efficiency and lower residual aluminum in treated water compared with PAC.The B value of PAC,the content(P%)of PDMDAAC and pH value effect on the coagulation efficiency and the residual aluminum.
