摘要
论述了天然沸石的吸附、离子交换和催化性能 ,介绍了沸石的超细粉碎、选矿提纯、化学增白、改性或改型、人工合成和再生等加工技术 ,从去除有机污染物、去除氨氮、降低氟含量、去除重金属离子、作污水滤料、消除放射性物质等方面回顾了沸石在水处理中的应用 ,并对应用前景和未来发展进行了展望。
The absorption, ion exchange and catalysis property of natural zeolite are expounded.Processing technology of natural zeolite is introduced from six aspects of ultrafine comminution,mineral purifying,chemical bleaching,modification,synthesizing and regeneration.The applications of zeolite in water treatment are reviewed,including removing organic pollutants,removing ammonia N,reducing fluorides,removing heavy metal ion,making filter media of wastewater and removing radioactive materials.Application prospects and further research are expected.
