摘要
零价铁(ZVI)作为一种具有较强还原性能的无毒氧化铁材料,近年来已经成为了污水脱氮处理领域的研究热点之一。介绍了零价铁脱氮的基本原理,分析了影响零价铁脱氮效果的主要因素,总结零价铁在污水脱氮处理中的研究进展和相关应用。通过零价铁相关脱氮技术目前存在的问题,展望了未来零价铁在污水脱氮处理中的发展方向。
As a non-toxic iron oxide material with strong reduction performance,zero-valent iron(ZVI)has become one of the research hotspots in the field of wastewater denitrification in recent years.This paper introduces the basic principle of zero-valent iron denitrification,analyzes the main factors affecting the denitrification effect of zero-valent iron,and summarizes the research progress and related application of zero-valent iron in wastewater denitrification treatment.Through the current problems of zero-valent iron-related denitrification technology,the future development direction of zero-valent iron in sewage denitrification treatment is prospected.
