摘　　要：化石燃料燃烧过程所排放的一氧化氮会对人体健康和生态环境造成巨大的伤害,已经引起了国内外广泛的关注。铁基络合脱硝作为湿法脱硝技术之一,与干法脱硝相比,脱硝效率更高,操作简单,具有很好的应用前景。介绍了铁基络合吸收一氧化氮工作原理,针对目前国内外循环再生研究现状以及实际生产过程中一氧化氮处理方法,将还原再生方法大致分为以下几类:含硫衍生物还原法、催化再生法、金属粉末还原法、微生物再生法等。针对这些方法的工作原理、优缺点以及现有的研究成果进行了介绍。根据当下脱氮发展现状,提出了铁基络合吸收治理发展的新方向。Nitric oxide emitted from the combustion of fossil fuels can cause great harm to human health and the ecological environment, and has attracted widespread attention at home and abroad. Iron-based complex denitrification is one of the wet denitrification technologies. Compared with dry denitrification, the denitrification efficiency is higher, the operation is simple,so it has good application prospects. In this article, the working principle of iron-based complexation to absorb nitric oxide was introduced. Aiming at the current research status of recycling at home and abroad and the nitric oxide treatment methods in the actual production process, the reduction and regeneration methods were roughly divided into the following categories: sulfur-containing derivative reduction method, catalytic regeneration method, metal powder reduction method, microbial regeneration method, etc. The working principles, advantages and disadvantages of these methods, as well as existing research results were introduced. According to the current development status of nitrogen removal, a new direction for the development of iron-based complex absorption treatment was proposed.
