摘　　要：1,4-二恶烷是一种新型的污染物,广泛存在于地下水、地表水和饮用水环境中,造成了潜在的公共健康风险。然而,1,4-二恶烷独特的化学性质,如高水溶性、低亨利定律常数,以及与氯化溶剂和其他污染物的共存,增加了有效清除1,4-二恶烷的挑战。本文综述了现有的处理水体中1,4-二恶烷的各类技术,重点介绍了化学氧化和生物修复技术的最新进展,为水体中1,4-二恶烷处理技术研究提供参考。1,4-dioxane is a new type of pollutant,which widely exists in groundwater,surface water and drinking water environment,causing potential public health risks.However,the unique chemical properties of 1,4-dioxane,such as high water solubility,low Henry's law constant,and coexistence with chlorinated solvents and other pollutants,increase the challenge of effective removal of 1,4-dioxane.In this paper,the existing technologies for the treatment of 1,4-dioxane in water are reviewed.The latest development of chemical oxidation and bioremediation technology is emphatically introduced,which provides a reference for the research of 1,4-dioxane treatment technology in water.
