Abstract

|
Recently, sanitary landfill was one of the most widely used for disposal of waste in Korea. With increasing of use and public awareness of this method for disposal. there is an increased concern With respect to the pollution potential by the landfill leachate. Especially, an aged landfill leachate contained relatively large amount of the nonbiodegradable substances which could not be removed by biological treatment processes. So, this study was conducted to the removal of nonbiodegradable substances, such as Humic acid and Fulvic acid with the electrolysis. In this study, electrode materials, electrolyte concentration, electrode distance, current density, and pH value were found to have significant effect on both pollutant removal efficiency and current efficiency in electrochemical oxidation process.
