摘要
沸石资源分布广泛、储量大,廉价易得,而且可以通过再生重复利用。沸石结构上的独特性和资源上的分布优势及其可循环利用的特点使其已成为废水处理工艺中常用的水处理剂之一,沸石具有物理吸附和离子交换特性,广泛应用于废水中氨氮、重金属、有机物和放射性物质的去除,是常用水处理剂之一。本文就其在水处理方面的应用、吸附机理、改性方法及再生方法的国内外研究进展进行了综述、分析,对沸石今后的研究工作进行了展望。
Zeolite is widely used in the wastewater treatment for its physical adsorption and ion - exchange property. It is of- ten used for the removal of ammonia nitrogen, heavy metals, organic compounds and radioactive substances. It has become one of the commonly used water treatment agent. In this paper, the latest research progress of the zeolite in wastewater treatment is re- viewed. The modification, adsorption and regeneration mechanisms of zeolite are analyzed and some suggestions for the future re- search on zeolite were also put forward.
