| 摘 要： | 采用不同碱化度B(OH/Al)值的聚合铝和AlCl_3对高岭土悬浊液进行凝聚絮凝实验,同时测定电泳度及表面吸附特征,结合不同铝盐的化学形态分布,探讨聚合铝的高效凝聚作用原理.并求得表面吸附覆盖率,电位变化与形态分布间的定量关系,绘出聚合铝的凝聚区域图,对阐明聚合铝的作用机理提供了实验依据.

| Abstract: | Coagulation jar tests were carried out by A1C13 and polyalumi-num of different basicities in kaolinite suspension. The micro-elec-tro-phoretic mobilities and adsorption parameters were also determined. The zeta potential change was related with the surface coverage and chemical species distribution. The coagulation diagram
of polyaluminum was compared with that of A1C13. In the light of experimental results the mechanism for superior coagulation function of polyaluminum was then discussed further. |
