水分散型阳离子聚丙烯酰胺的絮凝性能研究

通过高岭土模拟废水实验，考察了水分散型聚（甲基丙烯酰氧乙基三甲基氯化铵／丙烯酰胺）（以下简称CPAM）的投加量、阳离子度、分散剂分子量及其与PAC复配对絮凝性能的影响。结果表明，在絮凝过程CPAM表现出两个聚沉点，其适宜阳离子度和分子量范围分别为10％～15％和500×10^4～700×10^4，与PAC复配可显著增强其絮凝效果。

Study on Flocculability of Aqueous Dispersion of Cationic Polyacrylamide

The high molecular weight CPAM is used as flocculant to treat waste water. The effects of concentration, molecular weight, cationic degree and cooperation with PAC on the flocculation efficiency are investigated. It is found that two conglomeration values appear in the flocculation, and the optional molecular weight and the cationic degree are 10% - 15% and 500×10^4 - 700 - ×10^4 ,respectively. Good results could be obtained when they cooperate with inorganic flocculant PAC in the treatment of waste water.
