水库水源水的二次混凝效果分析与讨论

Analysis and Discussion of Secondary Coagulation of Reservoir Water

对聚合氯化铝、三氯化铁等混凝剂处理天然水样的混凝效果进行了系统的研究。结果表明:FeCl3对低温水的净水效果优于聚合氯化铝,FeCl3+PAM高效混凝技术对天然水样具有较好的混凝效果,COD的去除率达90.1%,浊度去除率达到90%以上。

Some coagulators are used to processing natural water such as polyaluminium chloride and ferric chloride etc and the coagulation results are systemiatically studied. The results show that ferric chloride are better than polyaluminium chloride using in processing low temperature water, while using polyaluminium chloride and ferric chloride simultaneously has a good result, 90.1% of COD are removed and more than 90% turbidity are removed.
