Abstract: The Fenton process on landfill leachate was done in a batch reactor. The application of Fenton treatment technology for landfill leachate treatment greatly depends on the optimum Fenton operating conditions. The present study investigated the chemical oxygen demand (COD) and color removal efficiency of a non-biodegradable leachate by Fenton process. Determining optimum Fenton conditions requires multiple experiments using variable reaction parameters (pH, temperature, and H2O2 and Fe2+ doses).The treatment showed that the leachate organics can be broke down by the use of Fenton’s reagent. The result showed that with increasing H2O2 dosage, H2O2/Fe2+ ratio and decreasing the pH and contact time, the COD and color removal increased. The laboratory result determined that the best functional situation to catch the goals _ (i.e., BOD5/COD =0.1) resulted; pH=3, Contact time=30 minutes, H2O2 concentration= 40000 mgL-1 and the favorable H2O2/Fe2+ ratio = 10.
