In this research, the performance of O3/H2O2 process for the removal the chemical oxygen demand (COD) of raw leachate landfill was studied. The experiments were conducted in a laboratory reactor. This research has been done in Graduate Faculty of Environment, University of Tehran, during the year 2018. In this study, the effects reaction time (0-120 min), pH (3-11), O3 mass flow rate (0-1.21 gr hr-1), and H2O2 dose (1-7 gr L-1) on the treatment of raw leachate landfill was studied. The Maximum removal efficiency of COD  at optimize operational conditions (reaction time: 60 min, pH 8.5, O3 mass flow rate 0.65 gr hr-1 and H2O2 dose 4 gr L-1) was 97% .

Keywords: Ozone, H2O2, COD, Leachate landfill.
