摘　　要：由于非平衡等离子体化学过程在增强氧化能力、促进分子离解以及加速化学反应等方面具有很高的效率 ,因此 ,近年来利用非平衡等离子技术对气体污染物的破坏分解研究受到了广泛的关注。本文简述了非平衡等离子体技术对气体污染物的降解原理 ,综述了国内外利用这一技术破坏各种气体污染物的最新进展 ,讨论了放电功率、停留时间、催化剂、化合物结构等因素对放电反应效率的影响 。Non thermal plasma chemical processes have been known to be highly effective in promoting oxidation, enhancing molecular dissociation, and enhancing chemical reaction, therefore, the decomposition of hazardous air pollutants by non thermal plasma has attracted more attention. This article simply describes the foundation of removal of hazardous air pollutants, summarizes the progress in the disposal of a wide variety of gaseous pollutants by different non thermal plasma technologies available. The factors effecting on the efficiency of discharge reaction, such as discharge power, retention time, catalysts, compound structure as well as the prospect of application have been discussed.
