淮南垃圾填埋场固液气热特性

Characteristics of MSW on solid-liquid-gas-heat in Huainan landfill

    摘要
  • 摘要: 已关闭的淮南大通垃圾填埋场建场24 a，最大堆填高度为15 m，垃圾最大填埋龄期达24 a。通过钻孔获取不同深度的6个垃圾样，土工试验结果表明：填埋场内垃圾最小孔隙比为1.18，最大孔隙比为2.53，塑料和纸张类含量对试样孔隙比影响较大；经过24 a的扩散，渗滤液透过了10 m厚的天然致密粘土层而对地下水体产生了污染；实测填埋场垃圾体内气体中CH4的最高体积分数达2.8654%，CH4/CO2比值在0.773～1.79；填埋体内最高温度大约发生在垃圾进场40 d后，达到56℃。针对垃圾填埋场固液气热特性，提出了填埋场治理措施的建议。

     

    Abstract: The characteristics of MSW(municipal solid wastes) on solid-liquid-gas-heat should be investigated and surveyed before the treatment. Six refuse samples were got by drilling in closed Datong Landfill in Huainan. The height of the filling MSW is about 15.0 meters and the oldest filling age of the refuse is near 24 years in Datong landfill. It was showed that the void ratio of the MSW was influenced by the volume of plastics and papers. The lowest void ratio of the samples is 1.18, while the maximum is 2.53. The 10.0 meters thick compact clay seam failed to prevent effectively the leachate from polluting the underground water. The maximum volume of the CH4was 2.8654%, while the value of CH4/CO2was between 0.739 and 1.79 in the landfill. The highest temperature of the refuse was 56℃, which occurred 40 days after the refuse entered the landfill. Based on the characteristics of MSW, some suggestion was made to treat the landfill.
