| 摘 要： | 采用静态通量箱/气相色谱法对河北某准好氧填埋场不同填埋龄作业台阶表面CH4气体的释放通量进行了测定。结果表明,准好氧填埋场作业台阶表面CH4气体的释放通量存在较大差异,其最大值和最小值分别为215.51和0.13g/(m2.d)。各填埋作业区中越靠近导气管的区域CH4气体释放量越大,而相同填埋作业区上午、中午和下午释放的CH4气体通量差异相对较小,但呈下午>中午>上午的趋势。填埋龄为8,12,16和20个月的各填埋作业区中CH4气体的平均释放通量分别为4.79,21.15,81.04和7.44g/(m2.d),并随着填埋龄的增加呈先增加后降低的趋势,在填埋16个月左右达到其释放高峰。此外,准好氧填埋场不同填埋龄作业区表面的CH4气体释放通量随着距离导气管距离的增加呈指数函数递减。

| Abstract: | Methane emission fluxes from active terrace surfaces of different landfilling age of a Municipal Solid Waster(MSW) semi-anaerobic landfill in Hebei Province were determined by the static chamber/gas chromatographic method.The results showed that significant differences were found among methane emission fluxes,with the maximum and the minimum being 215.51 and 0.13 g/(m2.d),respectively.The methane emission fluxes near the air pipe area were higher than the other areas,and the methane emission fluxes in the m... |
