中文摘要：

室内空气污染直接影响人群健康。传统的空气净化方法已不能满足室内空气净化要求，近年来，等离子体技术、光触媒技术及臭氧技术等空气净化技术开始被关注。该文着重阐述了等离子体技术净化室内颗粒物、挥发性有机污染物、微生物等空气污染物的潜能，分析了净化过程中可能引起的二次污染问题，评价了等离子体空气净化器在实际应用中的环境风险，并提出了等离子体技术在室内空气净化方面需要进一步研究的问题和方向。

英文摘要：

Human health is directly affected by indoor air. Traditional indoor air puntmatlon techniques can not meet me neens of people, in recent years, more attentions have been paid to the techniques of plasma, photocatalytic oxidation and ozone. Purification of indoor air using non-thermal plasma technology was introduced in this paper. Firstly, the applicative ability of non-thermal plasma technology in removing particle matter, volatile organic compounds and microorganism was stated. Secondly, the secondary pollutants and the environmental risk during the purification progress were discussed. Finally, the directions of future development were proposed.
