| 摘 要： | 为解决渗滤液直接回灌型垃圾填埋反应器(R1)的酸化问题,利用厌氧污泥复合床(UBF)和卫生填埋反应器组合为垃圾两相厌氧消化系统(R2)对垃圾降解。结果表明,与渗滤液直接回灌的R1生物反应器系统相比,UBF型两相厌氧生物反应器系统对渗滤液中有机物质的去除率更高,COD降至24600mg/L,NH3-N浓度保持在1130mg/L,pH值始终维持在7.26,为垃圾渗滤液的后续处理工艺提供了方便。此外,UBF型两相厌氧生物反应器产气性能更好,累积产气量是R1的3.06倍。

| Abstract: | The objective of this study is to resolve the problems involved in conventional landfill bioreactor with leachate recirculation such as the prohibition due to acid accumulation.UBF(up-flow blanket filter) is thus used as a secondary stage following the landfill bioreactor.The experiment shows UBF,the two-phase anaerobic reactor is better than the conventional landfill system in terms of organic degradation and biogas production. |
