Oxidation pretreatment of landfill leachate containing organic and inorganic pollutants can greatly enhance water quality while simultaneously increasing energy rich biogas production. Fenton's oxidation pretreatment of leachate was studied in an effort to obtain larger BOD(5)/COD ratios and to increase the BOD(5) value corresponding to higher yields of biogas. The results show that the optimum conditions for Fenton's oxidation were achieved with initial value of 20,000 mg/L H2O2, 180 mg/L Fe2+, pH of 6, and mass ratio of H2O2 to ferrous ion of 30. After pretreatment, the BOD(5) value increased from 69 mg/L to 3,808 mg/L. Biogas production was also increased significantly.
