| 摘 要： | 针对给水气浮浮渣,选用阳离子型、阴离子型、非离子型聚丙烯酰胺(PAM)以及聚二甲基二烯丙基氯化铵(HCA)作絮凝剂,调理后进行离心脱水试验,研究絮凝调理的最佳条件。试验结果表明低pH值有利于4种絮凝剂对浮渣离心脱水性能的改善;对于4种絮凝剂,都存在着一个最佳絮凝条件,其中阴离子型和非离子型PAM的最佳絮凝条件较阳离子型PAM和HCA需要更高的混合和反应转速以及更长的混合和反应时间。

| Abstract: | The best coagulation conditions of scum from waterworks were researched by centrifugal dewatering experiments with cationic polyacrylamide(PAM),anionic PAM,non-ionic PAM and polydimethyl diallyl ammonium chloride(HCA).The results showed that the low pH could improve the centrifugal dewatering properties of the scum,and there were best coagulation conditions for the four kinds of flocculants.On the best coagulation conditions,the anionic and non-ionic PAM needed higher mixing and reacting rotational speed as well as longer mixing and reacting time than that of the cationic PAM and HCA. |
