| 摘 要： | 二噁英(PCDD/Fs)是多氯代二苯并二噁英和多氯代二苯并呋喃的总称,因具有生物蓄积性、高毒性、难降解等特点而备受关注。垃圾焚烧是二噁英的重要来源,而其中超过50%的二噁英以飞灰形式排出。文章综述了热分解法、光降解法、机械化学法、生物降解法等飞灰二噁英毒性削减技术的国内外研究进展,并在此基础上对飞灰二噁英削减技术研究和管理提出了建议。

| Abstract: | PCDD/Fs are the general of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzo-furans.It is concerned because of the characteristic of bioaccumulation,highly toxic and non-biodegradation.Municipal solid waste incineration(MSWI) is the main source of PCDD/Fs,and above 50% of PCDD/Fs from MSWI is discharge into fly ash.In this paper,advance of the toxicity reduction technology of PCDD/Fs from MSWI fly ash was summarized,including thermal decomposition,photodegradation,mechanochemical treatment and biodegradation.Abase it,some suggestion was pointed out on study of reduction technology of PCDD/Fs from MSWI fly ash. |
