Paper Title:
Study on Removal Efficiency and Fluorescence Characteristics of Humus in Landfill Leachate Treated by Combined Process
  Abstract

The removal efficiency and three-dimensional excitation emission matrix(3DEEM) fluorescence spectroscopic characterization of landfill leachate humus (HA and FA) in the Fenton-SBR process was studied. It was concluded that the combined Fenton-SBR process was available for effective removal of leachate humus, and the removal rates for HA and FA was 87.3% and 88.2%, respectively. The major fluorescence peaks observed in the leachate combined process was protein-like fluorescence peak a (Ex/Em=280nm/345nm), humic-like fluorescence peak b (Ex/Em=295/400nm), short excitation wavelength tryptophan-like fluorescence peak c (Ex/Em= 230nm/340nm) and ultraviolet band fulvic acid-like fluorescence peak d (Ex/Em=235nm/400nm). Types of fluorescence peak of HA and FA reduced and the intensities decreased after combined process treatment. The capability for removal of different components of humus was determined by the process units adopted.
