摘　　要：城市垃圾焚烧飞灰由于其聚集着大量的重金属、二噁英、可溶盐等有害成分,被定义为一种危险废物.现有处置方法是对其进行安全化填埋或资源化利用,前者是目前的主流工艺.然而,随着土地资源的日益紧缺和人们环保意识的提高,更符合可持续发展的飞灰资源化技术近年来得到了广泛的关注.随着人们的持续开发与研究,已形成了多种各具特色的飞灰资源化技术,但总体而言,其仍多处于研究阶段,仅少数技术完成了工业化应用.本文根据最新有关飞灰资源化处理的研究报道,结合相关的行业标准及技术规范,对飞灰资源化处理的技术路线、产品、原理以及其各自存在的优缺点等进行了综述及评述,以期为飞灰资源化处理技术的实际工业化应用提供理论依据和技术参考.Municipal waste incineration(MSWI)fly ash is defined as a kind of hazardous waste due to large amounts of leachable heavy metals,dioxins,soluble salts and other harmful components contained.The main disposal methods of MSWI fly ash are safe landfill and resource reuse,in which the former is currently the dominant process.However,with the increasing shortage of land resources and rising awareness of environmental protection,recycling technologies more in line with the sustainable development have attracted widespread attention in recent years.A variety of recycling technologies for MSWI fly ash have been thus developed and reported.However,most of these technologies are still in the laboratory stage,and only a few of them have achieved industrial applications.This paper mainly reviews the technical routes,products of MSWI fly ash resource recovery,operation principles and the advantages and disadvantages of these technologies on the basis of the latest reports,relevant industry standards and technical specifications.This work can serve as a theoretical basis and technical guidance for the practical industrial applications of the resource reuse technologies for MSWI fly ash.
