Research on the Influence of Oxygen Concentration on Methane and Carbon Dioxide Concentrations in Semi-Aerobic Landfill

  • 摘要: 构建了准好氧填埋模拟装置,在其产气相对稳定期间,测定填埋装置内不同点位的ψ(O2),ψ(CH4)和ψ(CO2),并用数学模型对ψ(O2)与ψ(CH4)和ψ(CO2)之间的关系进行拟合.结果表明:随着ψ(O2)的增加,上层ψ(CH4)呈对数规律下降,而ψ(CO2)呈线性规律下降;中层ψ(CH4)和ψ(CO2)均呈指数规律下降;下层ψ(CH4)呈指数规律下降,而ψ(CO2)先保持在34%左右波动,当ψ(O2)大于1.8%后呈指数规律下降.上层主要为好氧带,ψ(CH4)低于ψ(CO2);中层主要为兼氧带,当ψ(O2)小于5.8%时ψ(CH4)高于ψ(CO2),而当ψ(O2)大于5.8%时ψ(CH4)低于ψ(CO2);下层主要为厌氧带,当ψ(O2)小于2.8%时ψ(CH4)高于ψ(CO2),而当ψ(O2)大于2.8%时ψ(CH4)低于ψ(CO2).
