| 中文摘要 |
| 在佛山市五峰山垃圾卫生填埋场安装地下废气监测井,对地下废气的组成与性质进行监测。在位于较迟填埋垃圾区域的监测井内,地下废气CH4、CO2的浓度较高、较稳定。在位于较早填埋垃圾区域的监测井内,地下废气CH4、CO2的浓度较低、变化也较大;且在最后一次监测中,井内的废气已失去了垃圾填埋场废气的特征,说明地下垃圾的厌氧分解过程已经完成或者厌氧环境已被破坏,前后只约持续了4a的时间,远低于预期所需的10-20a.比较了佛山市五峰山垃圾填埋场地下废气与香港船湾堆填区地下废气的差异,分析了引起差异的各种原因。根据地下垃圾有机碳的含量,估算了五峰山垃圾填埋场的废气产量。 |
| 英文摘要 |
| Five landfill gas monitoring wells were installed and the composition of landfill gases were monitored in Wufengshan landfill in Foshan,south China. For the wells located in the late landfilled region,CH4 and CO2 concentrations of landfill gases are high and stable.For the wells located in the early landfilled region,CH4 and CO2 concentrations of landfill gases are low and variable.In the last field measurement,the gases in the well located in early landfilled region has lost the characters or landfill gas. It's implication is that the biological decomposition process of the refuse underground has completed or the anaerobic environment has been destroyed.It just lasted for about 4 years and is much shorter than the expected time of 10-20 years. The differences of landfill gas between Foshan Wufengshan landfill and Hong Kong Shuen Wan landfill were compared and discussed. The yield of landfill gas in Wufengshan landfill was estimated according to the original carbon component of the refuse. |
