垃圾焚烧发电已成为我国城市生活垃圾处理的主要方式,随着焚烧烟气污染物排放标准日趋严格,烟气多污染物串联分步净化工艺存在流程长、占地大、设备多、投资和运行成本高的问题.为解决以上问题,垃圾焚烧烟气净化工艺有必要从"单一污染物控制"向"多污染物协同控制"发展,烟气多污染物一体化净化成为新趋势.讨论了垃圾焚烧烟气多污染物一体化协同净化技术的机理、技术特征、关键影响因素、优缺点以及工程应用情况,最后提出了对未来研究的建议和展望,以期为开发一体化净化新技术提供启示,并推动县域小型垃圾焚烧发电厂烟气处理的发展.
STATUS AND DEVELOPMENT TREND OF INTEGRATED TECHNOLOGY FOR MUTI-POLLUTANT CONTROL IN WASTE INCINERATION FLUE GAS
Incineration power generation has become the main way for urban solid waste treatment in China.With the increasingly strict emission standards of incineration flue gas pollutants,multi-pollutant removal through series of step-by-step purification has problems such as long process,large landing area,crowded equipment,high investment and operating costs.To solve the above problems,it is necessary to develop the flue gas purification process from single pollutant control to multi-pollutant collaborative control,and the integrated purification of flue gas multi-pollutants has become the new trend.This paper discusses the mechanism,technical characteristics,key influencing factors,and advantages and disadvantages of the multi-pollutant integrated collaborative purification technology for waste incineration flue gas,and its engineering application progress.Finally,suggestions and prospects for future research are put forward,hoping to provide some enlightenment for developing new integrated purification technology and promote the development of flue gas treatment for the small waste incineration power plants in counties.
