| 摘 要： | 通过对沸山市五峰垃圾清现场内部部分时段ＣＨ４浓度的监测，分析了在填埋场内部垃圾发酵过程中ＣＨ４浓度随时间的动态变化特征提出了利用某些统计曲线分别模拟或综合模块ＣＨ４浓度随时间的变化过程的方法，应用表明：本方法可以较准确地预测垃圾发酵主要内的ＣＨ４浓度随时间的变化，仅在垃圾发酵的尾声阶段，模拟浓度与实测浓度有少许出人。

| Abstract: | Methane concentration at some points was monitored and its dynamics was discussed in Wufeng Landfill. It is given how to use statistical curves respectively or synthetically to simulate the whole process of dynamics of methane concentration inside a landfill. It is demonstrated that it is more accurate to simulate methane concentration during the main period of degradation of Municipal Solid Waste by means of this method. Only a few simulating errors will occur during the last degradation period. The method is helpful to predict methane concentration at any time or average concentration during a period of time. |
