ABSTRACT The objective of the present work was the evaluation of the Fenton and photo: Fenton methods in the variation of the chemical demand of oxygen and demand for the treatment of leachates from the Cajamarca sanitary landfill, since they have been studied as the best alternatives for the treatment of organic materials in water. A solution of Fe and another of hydrogen hydroxide H 2 O 2 constitutes the Fenton reagent, when using Fe 3 + 2 + solutions it is called a Fenton type reagent, in which a highly reactive hydroxyl radical (•OH) is generated that can oxidize in polluting environments organic Both oxidant systems are more recent and need the assistance of energy, such as irradiation of sunlight and UV, these systems are called photo-Fenton processes. The raw leachate used was collected in the sanitary landfill of Cajamarca, Peru. The process was divided into three stages: field phase, laboratory phase and cabinet phase. In the field phase, samples of the leachate were taken before carrying out the previous treatment and parameters such as pH, chemical oxygen demand and biological demand of the possible values were determined: pH (9.1), COD (1051.5 mg O₂/L) and BOD (287 mg O₂/L). With these data it is possible to know the biodegradability index (IB) of 0.272, which indicates that the leachate is moderately biodegradable. The results in the laboratory phase of the treatment reflect favorable values in the application of the Fenton and photo - Fenton method, which presents a decrease of 9.2 mg O₂/L and 7.6 mg O₂/L in the evaluation of biological demand of oxygen, one of 536.6 mg O₂/L and 581.1 mg O₂/L and finally have a pH of 8.32 (Fenton Process) and 7.01 (photo Fenton). Finally, comparisons were made between the authorized users and the treatment giving acceptable results in the decrease of the chemical demand of the use of the Fenton method (although it was not achieved in the future) Permits of the MINAM and a decrease of the biological demand of oxygen and pH very favorable with the photo-Fenton method, reaching concentrations within the range of maximum permissible limits for domestic or municipal wastewater treatment plants.
