Diseño de un Biorreactor para obtención de Biogás y Bioabono a partir de residuos orgánicos del cantón Patate

Abstract

This research stud y was conducted to design a bio reactor to obtain both, bioga s and bio fertilizer from the organic waste in Patate Canton belonging to Tungurahua Province. It was carried out a quantitative and experimental technique for carrying out a sampling of the organic waste generated in the a rea by using a 2 litter sterile j a r, rubber boots and gloves. The process started by t he construction of an experimental model to make it possibl e to measure parameters such as temperature and the volume of bioga s produced in order to determine the optimal retention t ime in order to design the bior eactor under conditions as close as possibl e to reality, so, this time was in 47 subsequent days, when the presence of biog a s was determined at the moment of obtaining a blue flame. The selection of the type of bioreactor was conducted by an economic analysis, amount of waste, in the available are a as well as in the study area, being the Hindu bioreactor type (thin bell) adjusting to the necessary parameters of the canton. The final dimensions gathered from the bioreactor are: volume of the container 97m 3 , bioreactor height: 3.5m, Final height: 5m, Inlet and outlet chambers of the bioreactor: 2.21m, with a production of approximately 492 m 3 of gas daily. The design and subsequent construction of this bioreactor is aimed to reduce the environmental impact caused by organic waste generated, mainly the pollutant vectors generation. It is suggested that the Autonomous Decentralized Government of Patate canton makes the construction of this bioreactor in order to make a better usage os this waste, turning it into usable products for the community.
