絮凝剂在水处理技术中的应用

水资源污染状况在世界各地均十分严峻，河流及湖泊作为饮用水的主要来源被大量的工业及城市废水所污染。因此，对于污水的有效处理迫在眉睫。絮凝沉降法是目前使用最广泛的水处理方法，而絮凝剂的选择更是处理水污染问题最为关键的一步。本文主要论述了无机、有机、微生物及复合絮凝剂在水处理中的应用，分别对其优缺点进行分析，并探讨了四种絮凝剂在水处理领域的发展前景。

Application of Flocculant in Water Treatment Technology

The water resource pollution was serious all over the world. The main sources of drinking water such as rivers and lakes were contaminated by large amounts of industrial and urban wastewater. Therefore, effective treatment of sewage was urgent. Flocculation was the most widely used method in water treatment technology. The choice of flocculants was the most critical step in dealing with the polluted water. The application of inorganic, organic, microbial and composite flocculants in water treatment were discussed in this paper. The advantages and disadvantages were analyzed, respectively. The development prospects of four flocculants in the field of water treatment were investigated.
