摘　　要：天然斜发沸石是一种廉价矿物,经改性后可有效去除废水中氨氮、有机物、重金属离子、砷及放射性物质,并可用作杀菌剂。文章简述了天然斜发沸石的主要改性技术,并着重论述了近年来天然斜发沸石及各种改性斜发沸石在废水处理中的应用研究动态。同时,展望了其应用前景,探讨了目前应用斜发沸石处理废水时仍亟待解决的一些问题。Natural clinoptilolite is a kind of cheap zeolite mineral. After modification, the modified forms can be used effectively to remove ammonium ion, organic pollutant, heavy metal ion, arsenic and radioactive waste from wastewater, and also can be used as bactericide. Primary modified process of natural clinoptilolite was introduced, with focus on application of both natural and modified clinoptilolite in wastewater treatment. Some problems existed in application of clinoptilolite were discussed and analyzed as well.
