摘要/Abstract

摘要： 依据厌氧、准好氧填埋原理构建了填埋试验装置,对准好氧填埋CH₄、O₂浓度的动态变化进行了监测,并与厌氧填埋结构CH₄的浓度变化进行了比较.结果表明,准好氧填埋方式下、厌氧填埋方式下CH₄的平均浓度变化范围分别为7%～13%、35%～50%;准好氧填埋结构有利于减少CH₄气体的产生;CH₄浓度在准好氧填埋、厌氧填埋方式下都表现出明显的空间层次效应,呈现出下层>中层>上层的规律性;准好氧填埋结构的O₂浓度呈现上层>中层>下层的规律性.

Abstract: Based on the landfill principles,large scale installations of anaerobic and semi-aerobic landfills were established,with the concentrations of CH₄,O₂ and CO₂ detected regularly.The results showed that the average CH₄ concentration in semi-aerobic and anaerobic landfill installations was 7%～13% and 35%～50%,respectively,indicating the better effect of semi-aerobic landfill in reducing CH₄ production.The CH₄ and O₂ concentrations in the two landfill installations all presented obvious spatial layer effect,i.e.,under-layer > middle layer> upper layer for CH₄,while upper layer > middle level > under-layer for O₂.

Key words: Semi-aerobic, Municipal solid waste, Landfill gas, Methane
