摘要：
The treatment of landfill leachate by electro-Fenton (E-Fenton) method was carried out in batch recirculation mode. The effect of operating conditions such as reaction time, the Fenton's reagent dosage, Fe(II) to H2O2 molar ratio, electrical current, and initial pH on the efficiency of E-Fenton process was investigated. It was demonstrated that E-Fenton method showed the synergetic effect for COD removal. COD removal efficiency increased as the Fenton's reagent dosage increased at the fixed Fe(II) to H2O2 molar ratio, but further increase of the Fenton's reagent dosage would not improve removal efficiency significantly. The optimal conditions of Fe(II) to H2O2 molar ratio, electrical current and initial pH were determined based on the experimental results.
