| 摘 要： | 以乙醚为溶剂,丙烯酸二甲氨基乙酯与氯化苄进行季铵化反应,合成了新型季铵盐阳离子单体N,N-二甲基-N-苄基-N-内烯酰胺基氯化铵(DBAAC);再以DBAAC和丙烯酰胺(AM)为单体在水相中进行共聚制备了阳离子型絮凝剂DBAAC/AM共聚物(P(DBAAC/AM));用P(DBAAC/AM)处理高岭土模拟废水,采用正交实验,研究了n(DBAAC):n(AM)、聚合时间、聚合温度、引发剂K_2S_2O_8用量对P(DBAAC/AM)絮凝性能的影响;并以P(DBAAC/AM)为絮凝剂对污泥进行脱水处理。实验结果表明,合成P(DBAAC/AM)的最佳条件为:n(DBAAC):n(AM)=1:6,聚合温度60℃,K_2S_2O_8质量分数0.8%,聚合时间3h;用P(DBAAC/AM)对污泥进行脱水处理时,絮凝效果较好,所形成的絮体颗粒粒径大、沉降速率快;絮凝剂P(DBAAC/AM)的适宜加入量为6.0 mg/L。
