高级氧化技术处理1,4-二烷污染研究进展

随着工业的发展，各种新兴有机污染物不断出现，1,4-二烷作为其中之一，广泛存在于地表水和氯代烃污染的地下水中。由于其稳定的杂环结构及高水溶性，常规的水处理技术很难完全去除1,4-二烷，高级氧化技术利用?OH、\mathrm{S}{\mathrm{O}}_{\mathrm{4}}^{?-}等强氧化性自由基可有效地降解1,4-二烷。本文首先阐述了1,4-二烷的污染现状，重点概述了近年来国内外1,4-二烷降解的高级氧化技术，主要包括光催化氧化法、电化学氧化法和活化过硫酸盐氧化法等，深入分析了这些高级氧化技术对1,4-二烷的降解机理，并总结了这些技术用于处理1,4-二烷的降解效果及影响因素，最后提出了高级氧化技术处理1,4-二烷目前存在的问题及未来的研究和发展方向，以推动1,4-二烷污染处理技术的发展，为实际污染水体的治理奠定理论基础。

A critical review of advanced oxidation technology to treat 1,4-dioxane pollution

With the development of industry, various emerging organic pollutants continue to appear, as an emerging organic pollutant, 1,4-dioxane is widely distributed in surface water and groundwater with chlorinated hydrocarbons contaminated sites. Due to its stable heterocyclic structure and high solubility, it is difficult to completely remove 1,4-dioxane with conventional water treatment technology. Advanced oxidation technology utilizes strong oxidizing free radicals such as OH and \mathrm{S}{\mathrm{O}}_{\mathrm{4}}^{?-} to effectively degrade 1,4-dioxane. This paper describes the current status of 1,4-dioxane pollution, and focuses on the introduction of advanced oxidation technologies for the degradation of 1,4-dioxane at home and abroad in recent years, including photocatalytic oxidation, electrochemical oxidation and persulfate oxidation activation method, etc. Degradation mechanisms of these advanced oxidation technologies on 1,4-dioxane were deeply analyzed, and the degradation rates and its influencing factors for treating 1,4-dioxane were also summarized. Finally, the problems and development directions of advanced oxidation technologies for 1,4-dioxane pollution treatment were proposed, lay a theoretical foundation for the actual treatment of polluted water bodies.
