| 摘 要： | 通过分析上海老港生活垃圾填埋场填埋垃圾的腐殖质组成和光密度,考察了填埋垃圾的腐殖质组成和光学特性随填埋龄的变化规律.研究结果表明,填埋龄在1～14 a间的填埋垃圾中腐殖质组分的有机碳绝对含量的波动幅度很大,而腐殖质组分相对含量具有比较明显的变化规律,其中腐殖质总可提取率和wHA/wFA比值分别随填埋龄增加呈线性下降和上升的趋势.另一方面,填埋垃圾腐殖质光学特性研究表明,填埋垃圾可提取腐殖质和富里酸组分的E4/E6比值随填埋龄变化无明显关系,而胡敏酸的E4/E6比值则随填埋龄的增加呈线性下降趋势.因此,填埋垃圾腐殖质的总可提取率、wHA/wFA比值以及胡敏酸组分的E4/E6比值可有效地表征填埋垃圾和填埋场的稳定化进程.

| Abstract: | Aged refuse at Shanghai Refuse Landfill was sampled from the compartments closed from 1991 to 2004. The composition and light density of Humus fractions in age refuses were determined and their relationship with landfill age were studied. The results showed the following: total extraction rate of humic substance and E_4/E_6 ratio of humic acid fraction linearly decreased with landfill age, while HA/FA ratio of humic substance linearly increases with landfill age. Then these three parameters can be used as stabilization indexes of aged refuse and closed landfill compartments. |
