摘　　要：生活垃圾焚烧具有占地面积较小、周期短以及资源化利用率高等优点,已被广泛应用;但生活垃圾燃烧产生的飞灰中含有的二噁英和重金属易对环境造成污染,并且在填埋过程中产生的渗滤液不易处理。因此合适的飞灰填埋工艺对环境保护相当重要,本文主要探讨分区填埋飞灰并结合HDPE膜覆盖的协同作用,通过该协同处理可以有效避免飞灰中的二噁英逸出和重金属的渗出及渗滤液的产生,达到几乎零污染处理生活垃圾燃烧产生的飞灰。Domestic waste incineration has the advantages of small occupied area,short cycle,high resource utilization rate,etc.It has been widely used,however,the fly ash produced by the combustion of domestic waste contains dioxins and heavy metals,which can easily pollute the environment and the leachate produced which is not easy to handle during the landfill process.Therefore,a suitable fly ash landfill process is very important for environmental protection.This article mainly discusses the synergistic effect of district landfilling of fly ash combined with HDPE film coverage.Through this cooperative treatment,the escape of dioxins in fly ash,the exudation of heavy metals and the production of leachate can be effectively avoided,and almost zero pollution is achieved in the treatment of fly ash produced by domestic garbage.
