介质阻挡放电处理气态污染物的研究进展

Research Progresses in Treatment of Gaseous Pollutants by Dielectric Barrier Discharge Process

介质阻挡放电(DBD)由于具有分解效率高、能耗低、占地少等特点而逐渐成为研究的热点。介绍了DBD的特点、降解气态污染物的机理及发展历程;阐述了DBD单独处理、DBD-催化、DBD-紫外光、DBD-臭氧、DBD-湿式洗涤协同处理技术在气态污染物处理方面的研究进展;分析了DBD处理气态污染物的影响因素,并提出了今后的研究方向。

Dielectric barrier discharge （DBD） process has become a highlight in research due to its advantages such as higher removal efficiency, lower energy consumption and less ground demand. The characteristics of DBD, its development course and the degradation mechanism of gaseous pollutants are introduced. The research progresses in the treatment of gaseous pollutants by DBD, DBD- catalysis, DBD-ultraviolet light, DBD-ozone and DBD-scrubbing are presented. The factors affecting the treatment of gaseous pollutants by DBD are analyzed and the direction for future research is put forward.
