摘　　要：在利用直接过滤法处理大浪淀水库水应用研究的试验中,分别投加硫酸铝、聚合铝、聚合氯化铁、聚硅铝4种絮凝剂后,先根据进入床层前的水中颗粒的粒径分布情况进行了絮凝剂的筛选,同时以筛选的絮凝剂的处理效果作以比较,然后还对滤床各层截污分布情况进行了分析,最终确定了最适合的絮凝剂种类是聚合氯化铁。Four flocculants were put during the purification of the water of the Dalangdian Reservoir with direct filtration technique. The flocculants were selected on the basis of the grain diameter distribution of water before flowing into the filtration bed. Effects of the selected flocculants were compared. The intercept distribution in the different beds was analyzed. It was certained that the most suitable flocculant was polymeric chloride.
