Abstract
Up to date, the treatment of municipal landfill leachate in VietNam is insolvable. There are many problems have to be researched, especially tertiary COD treatment. Fenton oxidation process is able to treat COD to meet environmental standard. However operation cost is still high. Some results of the kinetics of Fenton process in laboratory condition show that : COD of leachate rapidly reduces because of instant hydroxyl (OH*) generation; After that, COD removal efficiency is low although hydrogen peroxide concentration is still high. The application of three step-by-step Fe2+ catalysis utilizes H2O2 residual, enhances COD removal efficiency and shortens reaction time.
