Discussion of influencing factors in electrochemical oxidation treatment of landfill leachate

Treatment of landfill leachate is a worldwide problem, and electrochemical methods can deal with it effectively. When the landfill leachate is treated by electrochemical methods , besides voltage, current, plate spacing and pH should be controlled , the electrode materials, CI^- concentration , Fe²⁺, Fe³⁺ additive amount and the dosage of aeration should also be controlled These factors on the leachate treatment effect can also have an important impact. According to water conditions , single factor experiments and orthogonal experiments should be used to select the most suitable electrode materials, CI^- concentration, Fe²⁺, Fe³⁺ dosing quantity and the dosage of aeration , in order to achieve the best removal efficiency.
