【摘要】:最近3年,水处理领域出现了高级还原技术(advanced reduction processes,ARPs)的新概念,该技术将紫外光(UV)等活化手段与亚硫酸盐(SO_3~(2-))、连二亚硫酸盐(S2O_4~(2-))等还原剂相结合,从而产生强还原性自由基,如水合电子(e_(aq)~-)、氢原子(H·)等,氯代有机物、氟代有机物等难降解有机污染物和高氯酸盐、溴酸盐、硝酸盐等无机污染物都能得到有效还原去除,在水处理领域有广阔的应用前景。目前,ARPs的研究才刚刚起步,本文在分析其基本原理的基础上,综述了国内外ARPs的研究现状,并就存在问题进行了研究展望,以期促进ARPs的发展。
[Abstract]:In the last three years, a new concept of advanced reduction processes (ARPs) has emerged in the field of water treatment, which combines the activation means such as ultraviolet light (UV) with reductant such as sulfite, so _ 3, S _ 2O _ 2, S _ 2O _ 4, and so on, thus producing strong reductive free radicals. For example, organic pollutants, such as hydrated electronic acidophane, hydrogen atom (H), chlorinated organic compounds, fluorinated organic compounds and other inorganic pollutants such as perchlorate, bromate, nitrate and so on, can be effectively reduced and removed, which has a broad application prospect in the field of water treatment. At present, the research of ARPs has just started. Based on the analysis of its basic principle, this paper summarizes the research status of ARPs at home and abroad, and makes a research prospect on the existing problems in order to promote the development of ARPs.
