摘要:AbstractPresent study has the aimed to assess the percentage of removal of chemical oxygen demand (COD) of non-biodegradable leachate from the landfill in the city of Loja (Ecuador) to be subjected to a Fenton process. Different concentrations of H 2 O2 and FeSO4 were combined in acidic pH values, obtaining removals close to 80% with a concentration of 500 ppm of H2O2 and 1000 ppm of FeSO4 at pH 4, thus establishing an optimum working radius H2O2/FeSO4 equal to 0.5. Through Box-Behnken stat istical analyses were determinates the significant factors, which correspond to the concentration of H2O2 and FeSO4 employed. With this information the process was optimized, reaching a theoretical removal of 81% at concentrations of 312 ppm of H2O2 and 1087 ppm of FeSO4 at pH 4. It was observed in this process removal of 79% of turbidity, 33% of Nitrates and 89% of Phosphates.
