Owing to its properties and composition, landfill leachate is one of the major environmental problems. The optimization of the leachate treatment, in order to completely reduce the negative effect on the environment, is a biggest challenge at the present time. For this purpose, the treatment of leachate by Fenton oxidation was studied. The Fenton oxidation is based on the addition of hydrogen peroxide to the leachate in the presence of ferrous salt as a catalyst. The leachate used in this study was obtained from Erzurum Municipal Solid Waste Landfill. Primarily, the characterization of leachate was determined. Later, the effects of various experimental parameters such as pH, amounts of hydrogen peroxide and ferrous on the leachate treatment were also investigated. During experiments done, changes of chemical oxygen demand (COD) and color were observed. The optimal conditions for treatment of leachate were determined as pH=2.5, Fe2+=2 mgL-1 and H2O2=100 mgL-1. Under the optimal conditions, approximately 90% color (at 620 nm), 84% color (at 525 nm), 74% color (at 436 nm) and 47.8% COD removal efficiency from leachate were achieved after 20 min of reaction. Depending on the results obtained in the experiments, Fenton process has been used successfully in removal of COD and color in landfill leachate.
