摘要
基于天然沸石的结构及其组成成分,阐述了天然沸石脱氮性能、改性方法及改性沸石脱氮性能、再生方法及其再生沸石脱氮性能,综合对比分析了天然沸石、改性沸石和再生沸石的脱氮效果。结果表明,利用天然沸石进行生物再生并循环利用,不仅节能、避免产生二次污染,又能要脱氮的同时去除其它污染物,而且可长期使用,是一种处理微污染水体的新方法,从而为解决水环境富营养化问题提供了新的思路。
Based on the structure and composition of natural zeolite,effects on nitrogen removal using natural,modified and regenerated zeolite were reviewed in this paper,as well as the methods of modification and regeneration.Furthermore,a comparative study on nitrogen removal by natural,modified and regenerated zeolite was carried out.The results show that nitrogen removal by bio-regenerated zeolite is a new method to treat micropolluted water and offers a new solution to the eutrophication problem.With zeolite suitable for long-term use,the method is energy-saving,pollution-free and highly effective for pollutant removal.
