摘要
絮凝沉淀法是广泛使用的水处理技术之一,而絮凝剂是絮凝法水处理的核心技术。与无机絮凝剂相比,有机高分子絮凝剂具有用量少、成本低、毒性小等优点,因此它的开发应用越来越受关注。而阳离子有机高分子絮凝剂由于带有可离解的阳离子更适合于水处理应用。本文介绍了阳离子聚丙烯酰胺类、天然高分子改性类、烷基烯丙基卤化铵类和环氧氯丙烷与胺反应类等阳离子有机高分子絮凝剂的研究现状,并对其发展趋势作了简单的展望。
Flocculation is one of technologies that are used in water and wastewater treatment.Flocculant is the core of the technology.Compared with inorganic flocculants,polymeric flocculants have some advantages,including economic,high efficiency,low toxicity and so on.which draw many attentions.Cationic organic polymeric flocculant can be more suitable in water treatment because of it has cationic groups that can be ionized in water.This paper introduces the synthesis and application of the cationic polymeric flocculants,including cationic polyacrylamide,modified cationic high polymer flocculants from natural high polymer,DMDAAC etc.
