摘要
在垃圾渗滤液原液中,溶解性有机质是总有机质的主要构成部分。溶解性有机质也是造成渗滤液生化处理出水COD较高的主要原因。从溶解性有机质的组成结构、分子量分布、元素组成、可见-紫外光谱和红外光谱特征等方面综述了有关垃圾渗滤液中溶解性有机质的研究进展,并总结了溶解性有机质的理化特性随填埋时间的变化规律。
The total organic matter in the raw landfill leachate is mainly composed of dissolved organic matter, and the dissolved organic matter is the main reason caused high COD of effluent of leachate treated by biological process. The current studies on the composing, molecular weight distribution, elemental composition, UV-visible spectra and FTIR infrared spectra of dissolved organic matter in the landfill leachate, and summarizes the variation rules of dissolved organic matter physical and chemical characteristics changed with the landfill time were reviewed.
