生活垃圾焚烧发电中二噁英控制技术研究进展

Research Progress on Dioxin Control Solution in Waste Incineration Power Plants

随着中国生活垃圾焚烧事业的蓬勃发展,垃圾焚烧过程产生的二噁英问题受到社会越来越多的关注,选择合适的控制技术手段来使二噁英的排放达到国家标准,是垃圾焚烧厂必须面对的问题。本文主要从垃圾预处理、炉内燃烧、尾部烟道、烟气净化及飞灰稳定化五个方面综述并总结在生活垃圾焚烧发电厂中二噁英控制技术研究应用进展,并提出了今后二噁英控制技术的研究方向。

With the rapid development of China＇s domestic waste incineration industry,dioxins generated in the waste incineration process receive given more and more attention.The selection of an effective control technology to eliminate dioxin in a bid to meet the national standards becomes an urgent problem needed to be solved by waste incineration plants.In this paper,the research progress of dioxin control technology was reviewed from the perspectives of domestic waste pretreatment,combustion in furnace,tail flue,flue gas purification and fly ash stabilization.Future research directions of dioxin control technology were proposed.
