水处理无机混凝剂的研究进展

概略评述了国内外无机混凝剂的研究进展。无机混凝剂可分为铝盐类、铁盐类、铁铝复合类、活化硅酸等，聚合氯化铝（简称ＰＡＣ）是目前水处理中广泛应用的无机高分子混凝剂。无机复合类混凝剂是近来年发展十分迅速的水处理剂，聚硅酸铝盐类是其中的代表。文中对无机混凝剂今后的研究工作提出了建议，认为在无机混凝剂的研制开发中，要加强应用基础性研究，产品多样化、专门化，要降低生产成本，提高产品质量，进行优化研究。

The research progress of water treatment of inorganic coagulating agent

This paper reviewed briefly the research progress of water treatment of inorganic coagulating agent worldwide.Inorganic coagulating agent can be divided into aluminate,molysit,aluminum-iron compound,activated silica gel and etc.polyme aluminum chlorid (PAC)is currently a type of inorganic polymer coagulating agent extensively applied in water treatment.Inorganic compound coagulating agent,represented by polysilicate aluminate,is the water treatment agent that is developing very fast recently.It was suggested,as to inorganic coagulating agent research and development in the future,that basic research be enhanced,product types diversified and specified,production cost lowered,product quality improved and optimized.
