摘　　要：沸石是一种架状结构的硅铝酸盐天然矿物材料,内部含有许多孔穴与通道,具有离子交换、高效选择性吸附及催化等优异的物化性能和良好的环境属性,在水处理研究与实践中得到高度关注。介绍了近年来国内外有关天然沸石在水环境治理领域的研究与开发成果,重点综述了基于吸附剂选择性考虑而出现的天然沸石与活性炭等吸附剂联合使用的技术,以及天然沸石对水处理中生物法及臭氧氧化技术催化作用研究的新进展。分析认为,天然沸石在水处理工程中具有非常广阔的应用前景,探讨了今后值得重点关注的研究方向。Zeolite is a natural aqueous silicate mineral with frame structure and numerous connecting holes. Particular crystal lattice structure makes it have excellent properties such as ion exchange, high efficient preferential adsorption, molecular filtration, dehydration, catalysis, acid resistance, heat resistance and radiation resistance. These specific properties make it possible to be widely used in water treatment. The recent domestic and foreign research achievements on the application of zeolite in water pollution treatment, particularly on complemetary action of zeolite with other ahsorhants, and the potential of zeolite to improve the efficiency of wastewater biotreatement and ozonation are reviewed. The research orientation in the future is also discussed
