Optimization of Fenton Process for Removal Organic Substance in Landfill Leachate

Abstract:

The treatment of landfill leachate by Fenton process was carried out in a batch mode. The effect of operating conditions such as reaction time, pH, dosage of H2O2 and [H2O2]/[Fe2+] molar ratio and temperature on the efficacy of Fenton process was investigated. It is demonstrated that Fenton’s reagent can effectively degrade leachate organics in 30 min. The optimal conditions were pH was 3, dosage of H2O2 was 2 times of theoretical stoichiometry, [H2O2]/[Fe2+] molar ratio was 5, temperature influence the removal efficency relatively small compared to other factors.
