文摘
Aqueous oxidation treatment of COD and color in landfill leachate with the combination of hydrogen peroxide and ferrous ion, Fenton reagent, has been studied. The effect of variables such as concentration of both reactants and pH has been investigated. Best concentrations seem to be 0.6 and 3.0?mol/L for H2O2 and Fe2+ ion, respectively. The other important variable, pH of landfill leachate should be near 7. From the experimental results can be known the determined process was the generation of hydroxyl radicals involving in advanced oxidation. Oxidation rates are even higher than those of other advanced oxidation systems involving ozone, UV radiation, and hydrogen peroxide.
