- 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 UV254 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 UV254>COD>DOC, respectively.
