铝盐絮凝剂絮凝性能和机理研究

On the Properties and Mechanism of Alumino- Salt Flocculant

系统研究了无机低分子铝盐、无机高分子铝盐以及无机铝盐和有机高分子絮凝剂ＰＡＭ复配使用处理高浊度原水的絮凝性能和机理，测定了电导率和粘度，并用显微摄影影拍摄了絮凝过程程不同阶段矾花大小的变化。为管式絮凝器的研制和铝盐絮凝剂的选择提供了理论依据。

In this paper, reseraches have been performed on the flocculent properties and mechanism of flocculants such as AlCl3、Al2(SO4)3·18H2O inorganic polyalumino - chloride,mixtures of AlCl3 and high polymers PAM in the water with turbidity>2000. The electroconductivity, the viscosity and the size changes of floes in the process of flocculation have been measured. The results might serve as theoretical basis in designing flocculators and adopting alumino-salt flocculants.
