摘要:

通过FentonSBR组合工艺对渗滤液溶解性有机物处理效果的研究,分析了溶解性有机物分子量分布及其3组份HA、FA及HyI的变化特性.研究发现,组合工艺对渗滤液中以COD、DOC及UV254表示的溶解性有机物总去除率分别为79.1%、73.6%和92.9%；对各分子量分布区间的去除效果较好,除10～4 ku分子量区间外,其余分子量区间COD去除率均在80%以上；同时,组合工艺对渗滤液DOM3组份的去除率为HA>FA>HyI,对3组份以UV254、COD和DOC表征的各指标去除率为UV25

Abstract:

The removal effect of dissolved organic matter（DOM）in landfill leachate by FentonSBR treatment process was investigated. And the changes of DOM molecular weight (MW) and the fractions humic acid (HA), fulvic acid (FA) and hydrophilic (HyI) in combined process was also analyzed. It is shown that the removal of COD 、DOC and UV254 was 79.1% 、73.6% and 92.9% with the combined process, respectively. The removal of COD was above 80% except for those with the molecular of 10～4 ku. The removal order of DOM fractions and three index of each fraction was HA>FA>HyI and UV254>COD>DOC, respectively.
