Abstract/Description: In this study, laboratory experiments were conducted to compare the efficiency of using O3 and O3+H2O2 as precursor to anaerobic biological treatment of the treatment of landfill leachate. Both oxidation systems were proven efficient in increasing the overall biodegradability of the leachate. At an ozone dose of 7.5ppm biodegradability of the leachate was increased by 25%, while a combination of 7.5ppm of ozone with 5ppm of hydrogen peroxide resulted in a 35% increase in biodegradability of the treated leacahte. Furthermore, this study investigated the efficiency of using the mentioned oxidation processes for overall enhancement of landfill leachate water quality and the degradation of endocrine disrupting compounds (EDCs) present in the leachate. The research proved the studied oxidants were able to decrease overall total organic carbon (TOC) concentrations and were responsible for the removal of a fraction of the total ammonia concentration from the studied landfill leachate. Furthermore, the research showed that ozone and the peroxone process had the ability to degrade EDCs that were present in leachate. Second order rate constants for the degradation of EDCs both in water and in leachate were also calculated in this study. The leachate treated in the experiments was categorized as having high ammonia, high TOC concentration, low biodegradability and low UV transmittance. The impact of ammonia, carbonates and other oxidant scavengers on the overall efficiency of the oxidants was also investigated in this study.
