摘　　要：以国外城市生活垃圾焚烧灰渣资源化利用现状为基础 ,讨论了灰渣利用的主要途径 :1石油沥青路面的替代骨料 ;2水泥或混凝土的替代骨料 ;3填埋场覆盖材料 ;4路堤、路基等的填充材料。已有的工程实践证明 ,只要控制处理得当 ,这些灰渣资源化利用可以不对人类健康和环境产生不利的影响。此外 ,也对灰渣资源化利用在环境标准和工程性质要求方面的规定及其采取的处理方法作了简单的分析。底灰经预处理后资源化利用 ,而飞灰经稳定化处理后填埋 。Based on the status quo of beneficial use of municipal waste combustion ash in some countries, the major ash uses are discussed in the paper, including aggregate substitute of asphalt pavement and concrete, landfill cover as well as fill materials of road base and embankment Existing demonstration projects and experiments have showed that, as long as well controlled, applications of beneficial use of bottom ash will not pose unacceptable hazard to human health and environments Engineering and environmental requirements for ash utilization are also analyzed A management strategy (beneficial use of bottom ash after pretreatment and landfill of fly ash after treatment) is proposed to solve ash problems that will occur in the near future in China
