新型环境友好材料──沸石在水处理中的应用

The Application of Zeolite in the Water Treatment—New Type of Environment-friendly Material

沸石由于具有较好的吸附性、离子交换性、催化性、耐酸性和热稳定性,在水处理中能够有效地去除水中的氨氮、有机污染物、重金属离子、氟、磷和含氧酸阴离子,并且在使用和处理过程中不会对环境造成二次污染,是一种环境友好水处理材料。结合沸石的结构和性能特点,综述了沸石在水处理中的应用,总结了在应用方面存在的问题,并展望了沸石作为曝气生物滤池填料的研究方向。

Zeolite is one kind of new style environment - friendly material with characteristics of absorption, ion exchange, catalysis, acid - resistance and thermal stability, which can effectively remove ammonia nitrogen, organic compounds, heavy metals, fluorides, phosphorus and acid anion containing oxygen and won＇t bring about secondary pollution in the course. In accordance with its structural and property characteristics, the application of zeolite in water treatment is described, the problems existed are summarized and the research orientation of biological filtering medial is prospected.
