摘要
随着工业废水和生活污水排放量的迅速增加,水处理问题日益突出,絮凝技术作为一种广泛使用且成本低廉的处理技术受到广泛的重视,它能够极大地提高水处理效率,其中最关键的一个问题是絮凝剂的选择。本文对无机盐类絮凝剂、无机高分子絮凝剂、有机高分子絮凝剂和生物絮凝剂的使用情况以及效果进行了综述,列举了近年来较为常用絮凝剂的应用机理以及研究进展,探讨了其优缺点。
With the rapid increase of emissions of industrial wastewater and domestic sewage,the problem of water treatment is becoming more and more prominent.As a widely used and low cost treatment technology,flocculation technology has been widely paid attention to.It can greatly improve the efficiency of water treatment.And one of the most critical problems is the selection of flocculant.In this paper,the application and effect of inorganic salt flocculant,inorganic polymer flocculant,organic polymer flocculant and biological flocculant are reviewed.The application mechanism and research progress of more commonly used flocculants in recent years are listed,and their advantages and disadvantages are discussed.
