摘要:

新型污染物1,4-二烷广泛分布于地表水、地下水和饮用水环境中。常规水处理手段对1,4-二烷难以奏效,因而其污染处理技术成为了关注的热点。本文主要针对1,4-二烷污染的处理方法进行了综述。首先对1,4-二烷的性质及分布特征进行了总结,比较了国内外已有的污染调查状况和控制标准,然后重点从物理、化学和生物法三个方面介绍了近年来1,4-二烷污染处理技术的最新研究进展,且分析了不同技术的作用机制、优缺点及可行性,并对不同技术的处理效率进行了归纳总结。文中特别指出了生物修复的难题,即氯代烃、重金属对微生物降解1,4-二烷的抑制作用和机理及改进修复技术,最后对今后的研究方向进行了展望。

Abstract:

As an emerging environmental contaminant, 1,4-dioxane is widely distributed in surface water, groundwater and drinking water. It is difficult to remove 1,4-dioxane by conventional water treatment methods, so its treatment technologies have attracted widespread attentions. In recent years, attentions have been paid to the environmental behavior of 1,4-dioxane and its adverse effects on human health. The remediation technologies of 1,4-dioxane were reviewed in this paper. First, the nature and distribution characteristics of 1,4-dioxane were summarized, and the existing pollution investigation and control standards at home and abroad were compared. Then the development of technologies for controlling 1,4-dioxane pollution in recent years were introduced from three aspects including physical, chemical and biological methods. The removal mechanism, advantages and disadvantages of different methods, and feasibility were also introduced. The inhibitory effect and mechanism of bioremediation methods under the coexistence of chlorinated hydrocarbons and heavy metals were pointed out, and the existing methods to deal with mixed pollutants were introduced. Finally, the main directions of future research on 1,4-dioxane pollution treatments were prospected.

Key words: emerging pollutants, environment, adsorption, advanced oxidation processes, bioremediation, 1,4-dioxane
