简述二噁英降解方法的研究进展

Review on the Degradation Methods of Polychlorinated Dibenzo-p-Dioxins/Furans

二噁英是一类剧毒的持久性有机污染物和一级致癌物质。脱氯降解是降低二噁英毒性的有效途径之一。本文首先介绍了二噁英的种类、来源和危害,其次对二噁英的降解方法包括光降解、光-Fenton降解、生物降解、热降解、化学降解脱氯作了简要评述,比较了各种降解方法的优劣。

Polychlorinated dibenzo--p--dioxins/furans （dioxins） is a kind of important persistent organic pollutants（POPs） and carcinogen. Dechlorination is an efficient means to eliminate the toxicity of dioxins. A review on the degradation methods was given in this paper.These degradation methods include photodegradation, photo--Fenton degradation; thermal dechlorination, biodegradation, chemical dechlorination. The advantage and disadvantage of the degradation methods were introduced.
