Abstract

Backgrounds and Objectives: Leachate is one of the landfill products and also a wastewaterbearing the most advers effects on the environment. Biological methods are usually employed forTREATMENT of young leachate (1-2 years) wich is of high concentration of organic compounds withlow molecular weight. However these methods are not approprate for mature leachate (5-10years) due to having high rate of compounds with molecular weight and the presence of materials resistant to biodegradation and toxic compounds. ADVANCED OXIDATION process such as FENTON reagent used in TREATMENT or biodegrability improvement of strong wastewater. In the present study the degrabilityimprovement of mature leachate through oxidation FENTON process in bench scale and in batch reactor has been investigated.Materials and Methods: The samples have been taken from Ahwaz landfill and factors such as initial COD and BOD, pH, BOD5/COD were studies as DEGRADABILITY, the amount of Hydrogen Peroxide, Fe(II), optimal reaction time and optimal pH.Results: The highest amount of COD removal was observed in PH=3-3.5 and 90 minutes of reaction time. H2O2=29700mg/land Fe2+=16500 mg/l in [Fe2+]/[H2O2]=1/14.8 molarity ratio were obtained as optimal amounts BOD5/COD was equal to 0.38.Conclusion: This study indicates that FENTON oxidation enhances the biodegradability of leachate.
