废气量减排对大气污染控制技术效率的要求

Research on Requirements of Air Pollution Control Technology Efficiency for Waste Gas Volume Reduction

雾霾问题已经成为我国目前面临的主要大气环境污染问题,废气量减排是消除我国雾霾污染的有效途径之一。综述了国内外废气量减排的现状,在此基础上分析了废气量减排对污染物排放浓度的影响。结果表明,废气量减排技术的应用对大气污染控制技术提出了更高的要求,需将除尘效率提高到99.95%,脱硫效率提高到97.5%,脱硝效率提高到75%。

The haze has become a major air pollution problem in China currently, and the waste gas volume reduction is an effective way to eliminate haze pollution.The present situations of the waste gas volume reduction at home and abroad were reviewed.On this base, the impacts of the waste gas volume reduction on the pollutant emission concentration were analyzed.Finally, the requirements of air pollution control technology efficiency were proposed for the waste gas volume reduction.Dust removal efficiency is 99.95%, desulf urzation effiency is 97.5%, and deNOx effiency is 75%.
