摘　　要：本文在对矿化垃圾的基本性质进行测定的基础上,将其作为填埋场覆盖材料进行室内模拟实验。结果显示:经过筛分后的矿化垃圾细料可作为回灌型准好氧填埋场的日覆盖材料,除了具有日覆盖材料的常规功能外,还有净化渗滤液的能力;矿化垃圾对渗滤液中污染物的净化能力优于普通砂土;矿化垃圾作日覆盖材料的最佳粒度为d≤3mm,最优厚度为13cm,双层结构对污染物的净化能力优于单层结构。所以矿化垃圾是一种性能良好的日覆盖替代材料。Based on the determination of the basic properties,the aged refuse was used as daily cover in indoor simulation experiment.According to the results,sieved fines in aged refuse can be used as daily cover in leachate recycled semi-aerobic landfill sites.It also has the ability of purifying landfill leachate besides the conventional functions.The purification ability of aged refuse is better than normal sand.Particles with a size less than 3mm and thickness of 13cm will be an optimal cover for daily use.Double-layer structure is better than monolayer structure in the ability of removing pollutants.The aged refuse can be used as daily cover due to its good performance.
