The present work evaluates the H2O2 oxidation process of the “Granja Quispe” slaughterhouse wastewater, with a batch bubbling reactor integrated with an airflow, stirrer, and temperature control system; and automated data acquisition for turbidity and pH, implemented with a micro-controller Arduino. The decrease of turbidity with the airflow (F), stirring velocity (V) and H2O2 concentration (C) is studied using a 23 multilevel factorial experimental design. The results show that the higher F, V and C, the greater the decrease in turbidity; being the variable with the greatest effect and statistical significance in the process, the concentration of H2O2 and an empirical model was stablished. At conditions of F = 200 ml / min, C = 90 mg / L and V = 300 rpm, t was possible to decrease 52.65% of turbidity, 83.9% of total organic matter and 72.97% of biodegradable organic matter in a time of 112.5 min, , conditions at which the sample efficiently complies with the established standard for non-domestic effluents; constituting an alternative for the treatment of water with a high organic pollutant load Keyphrases: Oxidación avanzada, Peróxido de hidrógeno, Reactor Batch, Turbidez, efluente de matadero
