生活垃圾焚烧烟气全过程污染控制技术和进展

Technology and Progress of Flue Gas Pollution Control of Municipal Solid Waste Incineration Whole Process

由于垃圾产量巨大,垃圾焚烧具有最大限度的减量化、无害化、资源化等优势,已成为城市生活垃圾处理处置的主导工艺。然而,垃圾焚烧过程中产生的各种气体污染物包括氮氧化物、硫化物、氯化物、氟化物、颗粒污染物,以及高风险的重金属和二噁英等污染物,需要进行有效控制,满足烟气排放质量要求。本文基于生活垃圾焚烧产生烟气的特点,分析了烟气排放控制和净化处理的技术,介绍了国内外一些新型烟气污染物排放控制及净化技术,并对垃圾焚烧烟气控制和净化技术的发展进行了分析和展望。

Due to the huge output of garbage,garbage incineration has the advantages of maximum volume reduction,harmlessness,and resource utilization,and has become the leading technology for urban domestic garbage treatment and disposal.However,waste incineration will generate various gas pollutants such as NO_(x),SO_(2),HCl,HF,heavy metals,dust,dioxin and so on.Therefore,the effective measures need to be taken to ensure that the flue gas is discharged up to discharge standard.Based on the characteristics of flue gas generated by domestic waste incineration,this paper analyzes the technology of flue gas emission control and purification treatment,introduces some new flue gas pollutant emission control technologies,and analyzes and prospects the development of flue gas control and purification technology for waste incineration.
