摘　　要：选用无机低分子铝盐、铁盐和无机高分子聚合氯化铝（ＰＡＣ）以及无机与有机高分子聚丙烯酰胺（ＰＡＭ）复配等絮凝剂处理高浊度原水，测定了余浊、水体密度与静沉时间的变化曲线；采用多次多因素多水平正交试验进行最佳水力条件选择，并结合矾花大小变化对絮凝过程动力学和机理进行深入研究，为管式絮凝器的研制提供理论依据。The optimum hydrodynamics conditions were obtained in the treatment of highly turbidity water using five different flocculents. The curves of change of the residual turbidity and water density with time of static sedimentation were measured. The study of flocculent process kinetics and mechanism gave useful information for the design of the pipe flow flocculator.
