摘　　要：介质阻挡放电(DBD)因其产生的低温等离子体能量密度高且能量体积大,可在温和的反应条件下无选择性地降解废水中大分子污染物,且反应高效、彻底,而被广泛应用于印染、制药、化工、农业等行业废水中难降解物质的实验室研究中。综述了DBD特性以及低温等离子体技术处理废水中污染物的作用过程和机理,总结和分析了影响污染物降解效果的关键因素,提出了尚未解决的技术难点和未来发展方向,以期为此技术的深度优化起到借鉴指导作用。Due to the high energy density and large volume of the non-thermal plasma generated by the dielectric barrier discharge(DBD), it can non-selectively degrade the macromolecular pollutants in wastewater under mild reaction conditions,and the entire reaction is efficient and thorough. Therefore, it is widely used in laboratory research of difficult-to-degrade substances in wastewater from printing and dyeing, pharmaceutical, chemical, agricultural and other industries. The characteristics of DBD and the process and mechanism of non-thermal plasma treatment of pollutants in wastewater were reviewed. The key factors affecting the degradation effect of pollutants were summarized and analyzed. The unsolved technical difficulties and the future development direction of non-thermal plasma were pointed out, in order to play a reference role in the deep optimization of the technology.
