Study on Treatment of Landfill Leachate Using an Integrated KMnO₄ Oxidation and Diatomite Adsorption Method

Abstract:

This study focused on the performances of an integrated KMnO₄ oxidation and diatomite adsorption method in the treatment of fresh landfill leachate. The optimal conditions and influential parameters for oxidation and adsorption were determined. The results showed that under optimum oxidation conditions for KMnO₄, the removal rates of COD_Cr and ammonia nitrogen reached 46% and 32% respectively. And the removal rates of COD_Cr and ammonia nitrogen contained in leachate increased up to 98% and 90% after absorbed by diatomite.
