垃圾渗滤液溶解有机质的红外和荧光光谱比较研究
摘要：分析了永川和江津地区的垃圾渗滤液的溶解性有机质（Dissolved Organic Matter, DOM）三维荧光特性，研究了三峡库尾部分地区垃圾渗滤液不同分子量区间的组成和荧光特性随填埋龄的变化规律。垃圾渗滤液的红外和荧光光谱表明，两个地区的主要有机物为含芳环氨基酸结构的有机物和含有羰基和羧基官能团的有机物。垃圾的堆放时间越长，渗滤液中类蛋白质浓度越低，类富里酸浓度越高，说明垃圾中的蛋白类物质在腐殖化进程中易于降解，腐殖化产生各种腐殖质。这对垃圾渗滤液的处理工作具有一定的指导意义。

Abstract: By analyzing the three-dimensional fluorescence characteristics of the landfill leachate dissolved organic matter (Dissolved Organic Matter, DOM) in Yongchuan and Jiangjin area, examining the composition of various molecular weight of landfill leachate and the variation regular pattern of fluorescence with the landfill age in the parts of the Three Gorges Tail and get the infrared and fluorescence spectroscopy, we find that the major organic matters in the two regions were that containing the aromatic amino acid and the structure carbonyl and carboxyl functional groups of organisms. Judge from the variation of three-dimensional fluorescence spectra with the time of garbage piling in two regions, we can conclude that the longer the pile of garbage, the lower concentration of protein in landfill leachate, the higher the concentration of fulvic acid, which indicate that the protein waste humic substances is easily degradable,in the process, and produce a variety of humus by humification. This has certain significance for the processing of landfill leachate.
