Landfill Leachate Treatment with Electrocoagulation

摘要

Electrocoagulation was applied to leachate treatment. Laboratory scale experiments were conducted with two electrode materials namely, aluminum and iron, Aluminum was selected in these experiments. The optimum working pH was found to be in the neutral condition, allowing leachate to be treated directly without pH adjustmet. The experimental conditions for leachate treatment by electrocoagulation were: electrode distance was 10mm, a current intensity of 60 A/m2 was selected. The removal efficiency of COD and N3H-N was about 46.7% and 76.4% respectively.
