生物修复技术减少垃圾填埋场甲烷气体排放的研究

Research on Reduce Landfill Methane Gas Emissions by Bioremediation Technology

垃圾场的甲烷释放是全球变暖的主要因素.本文通过分析垃圾填埋场的甲烷释放因素,提出了通过生物修复技术是减少垃圾填埋场甲烷排放,主要是通过先卫生填埋后植物覆盖的方式.地上部分通过对不同植被类型的筛选,确定出利于甲烷氧化的树种;地下部分通过卫生填埋和生物反应器方法相结合,有效地提高甲烷氧化分解能力,降低甲烷的释放量.对温室气体减排及改善垃圾填埋场卫生环境状况是良好契机.

Landfill methane release is a major cause of global warming.Factors,based on the analysis of the landfill methane emission is put forward through bioremediation technology is to reduce the landfill methane emissions,mainly by sanitary landfill before plant cover.Above ground through the screening of different vegetation types,determine the good for methane oxidative species.Underground part by sanitary landfill and combined bioreactor methods,effectively improve the decomposition of methane oxidation ability,reduce the amount of methane release.It is a good opportunity on greenhouse gas emissions and improve health conditions of landfill site.
