| 摘 要： | 针对现有研究温度设置较少的现状,提出通过5个不同温度的设置来模拟温度对填埋有机垃圾厌氧降解的影响。结果表明,温度控制在41℃和45℃的模拟垃圾柱C4和C5,在实验进行到140d,渗滤液COD浓度分别由最大值86614mg/L和90000mg/L降低到5216.5mg/L和5413.4mg/L,渗滤液中COD浓度分别降低了93.98%和93.99%,同时垃圾柱C4产生的填埋气体中甲烷含量最高且稳定,从而显示了实施温度控制对渗滤液污染防治和填埋气体回收利用的强大优势。该项研究为加速厌氧填埋场中垃圾的稳定化进程提供了参考。

| Abstract: | Five different temperature values were set to study the effect of temperature on anaerobic degradation of organic solid waste in landfill. Results showed that under the conditions of simulated columns C4 and C5 whose operation temperature was controlled at 41℃ and 45℃, COD concentration in the leachate dropped from 86,614mg/L and 90,000mg/L to 5,216.5mg/L and 5,413.4mg/L respectively, with corresponding COD removal efficiency up to 93.98% and 93.99% respectively and the composition of methane in landfill gas in simulated column C4 up to the maximum, which indicated that high temperature had the advantage in COD removal efficiency and recycle of landfill gas. The study is of significance to accelerate solid waste stabilization in landfill. |
