| 摘 要： | 依据准好氧填埋的原理,构建了大型模拟填埋场。对准好氧填埋结构渗滤液回流情况下填埋气产气过程做了跟踪监测。定期测定填埋气中的组分浓度变化,结合填埋场渗滤液水质变化进行分析。结果表明准好氧填埋条件下进行渗滤液回流有利于减轻渗滤液的排放量且不会造成NH4+-N的累积。渗滤液回流可以加快甲烷的产气速度,渗滤液回流时的甲烷浓度约为不回流时的甲烷浓度的2倍。从而可加快垃圾的稳定化进程。

| Abstract: | A simulated large scale landfill was established according to the semi-aerobic landfilling theory.A tracer monitoring for the landfill gas concentration variation on the condition of leachate recycling as compared with that of the un-recycling in semi-aerobic landfill.The results shows that leachate recycling in semi-aerobic landfill reduces the amount of leachate, and does not cause the accumulation of NH _4-N concentration.On the other hand, leachate recycling in semi-aerobic landfill can cause the velocity of methane production faster.The methane concentration in leachate recycling system doubled than the un-recycling one.So it does good to accelerate the stabilization of landfill. |
