氮氧化物污染现状和控制措施

Status and Controlling Measures of Nitrogen Oxides Pollution

氮氧化物(NOx)是大气主要污染物之一,也是目前大气污染治理的一大难题。该文重点对选择性催化还原法(SCR)、选择性非催化还原法(SNCR)和电子束脱硝技术(EBA)等烟气中NOx控制技术的原理、应用现状、优缺点及存在的问题进行了详尽的论述,并最终展望了烟气脱硝技术未来的发展方向。

Nitrogen oxides are one of the main air pollutants,as well as a difficult problem in air pollution control.The removal principle,the advantages and disadvantages,existing problems,the present situation and the application technology of the NOx from the flue gas,such as SCR,SNCR and EBA are introduced in detail,and the development orientation of flue gas gentrification technology is finally presented.
