摘要
高效混凝剂聚合氯化铝是目前水处理研究开发的热点,它具有用量少、污泥少、除浊高,对出水pH影响小等优点,是污水处理中的理想絮凝剂。因而对国内外聚合氯化铝制备技术的研究进行了评述,归纳了不同原料生产聚合氯化铝工艺技术,分析了各类聚合氯化铝混凝剂的优点,并介绍了聚合氯化铝生产工艺的主要改进技术。
High quality polyaluminum chloride (PAC) coagulants are the research focus of water treatment at present. It reviews briefly the research progress of the preparation of polyaluminum chloride in recent years. The process and technological conditions of manufacturing polyaluminium chloride from some different raw materials are introduced. In addition the improvements of technological conditions are put forward.
