天然沸石在环境污染治理中的研究现状和发展趋势

The Application of Zeolite to Treatment of Environmental pollution:Its Status Quo and Tendenay

天然沸石在环境保护领域中的应用研究已成为近年来非金属矿物材料研究的热点之一。在简述中国天然沸石资源概况及其主要物理性能的基础上,对近年来天然沸石在空气净化、水污染处理、除臭抗菌、固体废弃物处理和催化剂载体等环境污染治理中的应用研究现状进行综合评述,并探讨其发展趋势,认为寻找将沸石的吸附作用与其他技术相结合处理污染水源,探讨沸石处理各种水源的最佳工艺条件和参数,确定合理的沸石再生方法以及天然沸石的复合加工,是今后沸石在环境保护领域开发利用中的主要发展趋势。

The natural zeolite which has been applied in environmental protection has become one of the research hot spots of non-metallic mineral materiasl in recent years. The authors reviewed status quo of its application and its main physical properties of natural zeolite. In the past decade, natural zeolite have been widely applied to the control and treatment of environmental pollution, such as air purification, water treatment, deodorization and antibacterial, solid waste disposal and catalysts-loaded media. And the development tendency are also discussed. The authors considered that combining zeolite adsorption with other technologies to deal with pollution water, obtaining the optimal working conditions and parameters of zeolite to deal with all kinds of water source, identifying the reasonable zeolite regeneration method as well as the natural zeolite compound processing, will be the main research topics of natural zeolite in the future.
