Evaluación experimental del potencial de producción de biogás a partir de aguas residuales procedentes del Camal Metropolitano de Quito

Abstract

Slaughterhouse wastewater can be revalued energetically through anaerobic digestion and remove organic matter. Therefore, the objective of the present investigation was to experimentally evaluate, through batch reactors, the potential for the production of biogas from wastewater from a pilot plant at the Municipal Slaugtherhouse of Quito. The methodology used batch reactors in triplicate for each sample of the pilot plant of the Metropolitan Camal of Quito. The biomethanization potential was determined experimentally at an optimum temperature of 37 °C and using autochthonous inoculum typical of the microorganisms present in these wastewater. Five samples in total were analyzed corresponding to: E BDG1, S BDG1-E BDG2, S BDG2-E BDG3, S BDG3-E BDG4, S BDG4. The specific methanogenic activity was previously analyzed for each sample at a temperature of 19 and 37 ° C. Finally, the biogas production of the pilot plant of the Municipal Slaughterhouse of Quito at environmental conditions (19 ° C) was theoretically evaluated by applying the Roediger Kinetic Model adjusted to the experimentally obtained kinetic data (37 ° C), to obtain an estimate of the production of biogas on a real scale.
