Estudios y diseños definitivos para la obtención de biol a partir del proceso de compostaje realizado en el relleno sanitario de Porlón, Riobamba

Abstract

The objective of this work was to carry out the final Studies and Designs that allow proposing a technical system for obtaining biol from the composting process in the Porlon Landfill. First- hand information was collected by weighing and identifying the waste destined for composting from the Wholesale Market; nine samples composed of different types of biols were obtained, pure biol was obtained in the ESPOCH and diluted with water using rotating drum-type equipment, and pure biol was obtained directly in Porlón. At the same time the biol was obtained the daily generation rate of the same (leaching) was determined similarly. All the biols' physicochemical and microbiological characteristics were determined using instrumental and laboratory analytical techniques; these characteristics were compared. With the requirements of Ecuadorian technical manuals, based on said characterization, the design of a biol treatment system was proposed, taking into account the future population of the Riobamba canton and the conditions of the free land for construction near the composting platform. The results indicated that the composting platform receives approximately 9 to 12 tons of weekly wastes. For most legumes and vegetables, it was determined with the experiments carried out and the scaling of the same that the highest flow generated was 1.19 m3 / day on day ten after starting the composting; the most significant problem identified after the characterization of the biols was the lack of macronutrients, high presence of total solids, and presence of pathogenic microorganisms. The final proposed design consists of two grating systems, two storage tanks, a Parshall trough, two grease trap settlers, an aeration system, a standardization tank, and two drying beds.
