摘　　要：垃圾焚烧飞灰属于危险废物,但只要控制得当,亦可在消除其对人类健康和环境产生的不利影响的前提下进行飞灰的资源化利用。在总结目前国内外飞灰资源化利用途径的基础上,对其中如水泥、混凝土、制砖陶瓷、玻璃陶瓷、沥青路面、路基、堤坝、农业、吸附剂、污泥调理等11种资源化利用途径进行了对比分析。结果表明,飞灰用作路基材料所需技术层次较低,并在使用过程中避免与人直接接触,环境影响较小,且飞灰用量较大,是目前我国进行垃圾焚烧飞灰资源化利用较好途径。Though fly ash from municpal solid waste （MSW） inceneration is a hazardous waste,but so long as it is properly controlled, the utilization of fly ash resource, under prequisite of elimination of its harmful influence upon human health and the environment, can be realized. Based on summarizing ways of utilizing fly ash resource at home and abroad up to the present moment,a comparative analysis of eleven utilizing ways for fly ash resource, such as cement, concrete, brick - making, ceramics, glass - ceramic, bituminous roadsurface, roadbed, dykes and dams, agriculture, absorbent, and sludge - opsonizing etc. ,has been carried out. Results show that the utilization of fly ash resource as roadbed material needs only lower level of technical skill, avoiding direct contact with human body in the process of use, having little influence upon the environment,and the demand amount of fly ash is large, being a better way for utilizing the fly ash resource from MSW inceneration in China at present.
