Effects of Environmental Factors on Landfill CH4 Oxidation and N2O Emissions in Compounds with Aged Refuse, Cow Dung and Sawdust

  • 摘要: 在垃圾卫生填埋处理技术中,覆土材料的选择对处理成本和技术都至关重要. 探究了新型覆土材料(矿化垃圾+牛粪+木屑)的CH4氧化能力,并进一步分析了温度、含水率、初始φ(CH4)和好氧厌氧等环境因素对CH4氧化能力的影响. 结果表明:①新型覆土中矿化垃圾的填埋龄不同,其CH4氧化能力也有所差异,填埋龄较久的覆土B(10 a)、C(15 a)在培养时间内对CH4去除率和氧化速率均明显高于覆土A(5 a);②当温度为30 ℃、含水率为35%时,新型覆土的CH4氧化能力最高;③用米歇尔-门坦方程表征CH4降解的过程,R2(相关系数)为0.993,CH4氧化速率最大值为5.21 μmol/(g·h),半速常数为5.48%;④厌氧环境中新型覆土具有CH4氧化能力,而厌氧环境中CH4去除率相对好氧环境更慢,培养20 d后,厌氧环境CH4去除率为83%;⑤当土壤孔隙含水率分别为46%、70%时,覆土干湿交替导致的N2O和CO2释放量远小于CH4氧化量,故N2O增温效应可忽略. 由矿化垃圾+牛粪+木屑组成的新型覆土材料的CH4氧化速率最大值比现有覆土材料高1~2个数量级,其可应用于不同类型填埋场,特别是降雨较多的南方垃圾填埋场,可有效减缓垃圾填埋气CH4的释放影响.
