【摘要】:最近3年,水處理領域出現了高級還原技術(advanced reduction processes,ARPs)的新概念,該技術將紫外光(UV)等活化手段與亞硫酸鹽(SO_3~(2-))、連二亞硫酸鹽(S2O_4~(2-))等還原劑相結合,從而產生強還原性自由基,如水合電子(e_(aq)~-)、氫原子(H·)等,氯代有機物、氟代有機物等難降解有機污染物和高氯酸鹽、溴酸鹽、硝酸鹽等無機污染物都能得到有效還原去除,在水處理領域有廣闊的應用前景。目前,ARPs的研究才剛剛起步,本文在分析其基本原理的基礎上,綜述了國內外ARPs的研究現狀,并就存在問題進行了研究展望,以期促進ARPs的發(fā)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.
