Degradation of Landfill Leachate by Combined Three-Dimensional Electrode and Electro-Fenton

Abstract:

Three-dimensional-electrode electro-Fenton is a newly electrochemical oxidation technology to treat landfill leachate. In contrast, the removal efficiencies of COD and color in DSA system are obviously higher than those in iron anode system and the organics can be degraded more thoroughly. Under the optimal operating conditions, the removal efficiencies of COD, NH3-N and color in landfill leachate by DSA system are up to 80.8% ,55.2% and 98.6％. Besides, the reaction mechanism of three-dimensional-electrode electro-Fenton is also discussed.
