| 摘 要： | 采用静态箱-气相色谱法测定了河北省某准好氧填埋场作业台阶表面的温室气体CO2释放通量,分析了填埋时期和导气管距离对CO2释放通量的影响。结果表明:导气管附近区域表面的CO2释放量较大,且不同区域的CO2释放通量存在明显差异(最大值和最小值分别278.6和12.5 g/(m2.d);同一区域上午、中午和下午的CO2释放通量差异相对较小,但中午和下午高于上午。同时,填埋4、8、12和16个月区域的CO2平均释放通量分别为56.9,70.0,110.2和47.0 g/(m2.d),即CO2的释放通量随着填埋龄的增加呈现先增加后逐渐降低的趋势,并在填埋12个月达到CO2释放通量的最大值。此外,各填埋区作业台阶表面CO2释放通量随着距离导气管距离的增加呈指数函数递减的趋势。

| Abstract: | Carbon dioxide emission fluxes from active terrace of municipal solid waste semi-anaerobic landfills were determined by the static chamber-gas chromatographic method,and then the impacts of landfill ages and distances from air pipe on carbon dioxide emission fluxes were analyzed.As the results shown,the carbon dioxide emission fluxes near the air pipe area were higher than the other areas,and the significant differences were found between carbon dioxide emission fluxes in different area(the maximum and the ... |
