| 摘 要： | 考察了Fenton反应对渗滤液中DOM的处理效果,分析了Fenton反应前后DOM各组成成分及其表观分子量的变化.研究表明,Fenton对DOM的去除效果较好,其COD和DOC的去除率均在50%以上,UV_(254)的去除率达到84.5%.处理前,HA和FA为DOM主要组成部分,其COD、DOC及UV_(254)总和质量分数分别为DOM总量的77.5%、76.2%和86.70/0,处理后渗滤液中DOM以FA和Hyl为主,两者的COD、DOC及UV_(254)总和质量分数分别为DOM总量的97.6%、95.2%和95.1%.Fenton反应前,HA中以>4k的有机物为主,FA和Hyl则以<4k的有机物为主,反应后,3组分中均以<4k的有机物为主要组成部分,并且,Fenton对渗滤液中DOM3组分各指标的去除能力总体呈现HA>FA>Hyl的趋势.

| Abstract: | This changes of DOM in landfill leachate by Fenton reaction, and then analyzed the changes of humic acid (HA), fulic acid (FA) and hydrophilic (Hyl) fractions and their molecular weight (MW) in the landfill leachate were analyzed. The results showed that COD and DOC removal rate could exceed 50%, and UV254removal rate was about 84.5%. Before Fenton process, HAand FAfractions was the main parts in DOM, and COD, DOC and UV254of the two parts were 77.5%, 76.2% and 86.7% in total DOM, respectively. But after Fe... |
