摘要/Abstract

摘要： The performance of UV/H2O2, UV/O3, and UV/H2O2/O3 oxidation systems for the treatment of
municipal solid-waste landfill leachate was investigated. Main objective of the experiment
was to remove total organic carbon (TOC), non-biodegradable organic compounds (NBDOC) and
color. In UV/H2O2 oxidation experiment,with the increase of H2O2 dosage, removal
efficiencies of TOC and color along with the ratio of biochemical oxygen demand (BOD) to
chemical oxygen demand (COD) of the effluent were increased and a better performance was
obtained than the system H2O2 alone. In UV/H2O2 oxidation, under the optimum condition H2O2
(0.2 time),removal efficiencies of TOC and color were 78.9% and 95.5%, respectively, and
BOD/COD ratio was significantly increased from 0.112 to 0.366. In UV/O3 oxidation, with the
increase of O3 dosage, removal efficiencies of TOC and color along with BOD/COD ratio of
the effluent were increased and a better performance was obtained than the system O3 alone.
Under the optimum condition UV/O3 (50 mg.min-1), removal efficiencies of TOC and color were
61.0% and 87.2%, respectively, and BOD/COD ratio was significantly increased from 0.112 to
0.323. In UV/H2O2/O3 system, color removal and BOD/COD ratio were improved further and TOC
removal efficiency was found to be 30.4% higher than the system UV/O3 without H2O2.
