摘要
絮凝剂在水处理中已广泛应用,它是通过压缩双电层、吸附电中和、吸附架桥和沉淀物网捕等机理达到去除污染物的目的。聚硅酸盐絮凝剂是新型复合无机高分子絮凝剂,它比传统无机絮凝剂效果更优异,比有机高分子絮凝剂价格更便宜。介绍了包括单阳离子、双阳离子、三阳离子及多阳离子等聚硅酸盐絮凝剂的研究进展。对聚硅酸盐絮凝剂的发展方向进行了分析。
Flocculant has been widely used in water treatment, and it can remove pollutants by mechanisms of compressing double electric layer, adsorption electrical neutralization,adsorption bridging, sediment trap and so on. Polysilicate flocculant is a new type of composite inorganic polymer flocculant, it is more excellent than traditional inorganic flocculants, and cheaper than the organic polymer flocculants .In this paper, research progress in polysilicate flocculants was introduced, and the development trend of the polysilicate flocculants were analyzed.
