【摘要】 通过对上海老港生活垃圾填埋场1991—2004年封场单元填埋垃圾腐殖质组成的分析,考察了填埋垃圾中腐殖质组成随填埋龄的变化规律。研究结果表明,填埋垃圾腐殖质的总可提取率和胡敏酸(HA)与富里酸(FA)比值(HA/FA)分别随填埋龄呈线性下降和上升趋势。因此,填埋垃圾总可提取率和HA/FA可用来有效表征填埋场和填埋垃圾稳定度。更多还原

【Abstract】 Aged refuse at Shanghai Laogang MSW Landfill was sampled from the compartments closed from 1991 to 2004;the humus fractions in samples were determined. The total extractable quantity (by 10% of 0.1 mol/L NaOH, after 4 h of mixing) decreased linearly, while the HA/FA increased linearly,with increasing landfill age;therefore,the two humus composition indices may be employed as simple stabilization indicators for aged refuse and closed MSW landfill compartments.更多还原
