摘要：
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 SO•-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. © 2021, Chemical Industry Press Co., Ltd..
