| 摘 要： | 通过实验室填埋柱模拟实验，研究了生物反应器填埋操作方式对填埋层沉降的影响。结果表明：与传统卫生填埋方式相比，回灌经厌氧生物处理后渗滤液的生物反应器填埋方式能够加速填埋层的沉降，140 d内沉降提高比例达10%以上。我国填埋垃圾高含水率、高易腐有机物含量的特性，使得其填埋层的次沉降系数高于文献值。填埋垃圾有机物降解量及其引起的垃圾水分排出量与填埋层沉降有显著相关性，表明有机物降解是引起填埋层沉降的重要因素，也是造成生物反应器填埋与传统卫生填埋方式初期沉降差异的主要原因。

| Abstract: | The effects of bioreactor landfill operation patterns on the landfill settlement were studied by lab-scale experiments.The results indicated that comparing to the traditional landfill,recirculating the leachate which was pretreated by anaerobic process can increase the settlement of the landfill by more than 10% during the initial 140 days.Because the waste dumped in landfill was of high water content and putrefacient organic matters,the coefficients of secondary compression in this experiment were higher t... |
