Diseño de un biodigestor anaeróbico para la obtención de biogás, a partir de las excretas de ganado vacuno en el Rancho Guadalupe, en el Cantón Mocha Provincia de Tungurahua en el año 2015

Abstract

It was made the "Design of an anaerobic biodigester to obtain biogas, draw from the excreta of the beef cattle in ranch Guadalupe, in Mocha Canton Tungurahua province in 2015" to take advantage and give good management to excreta of beef cattle, first it made to recognition of the sector to know the base l ine was performed, data were collected through a survey in which it verified the acceptance of the inhabitants of the place to execute a design of this type in the future to implement it in its properties, It followed this was obtained data by analysis of field and laboratory for microbiological and physicochemical characterization of excreta of livestock, a suitable biodigester to the ranch was selected and finally it was dimensioned the tubular biodigester streaming polyethylene as the most appropriate the needs of Rancho Guadalupe, It also developed a greenhouse design that will cover the biodigester to increase the temperature in the reactions. As results with a daily load of 138,95Kg / day of excretas, the dimensions of the trench are 1m high, 1.5m upper trench width, 1.2m, lower trench width and length 9,63m. We conclude that the biodigester will produce biogas 4,51m3 dia after a retention time of 45 days. It recommend to the owner of the ranch consider implementing biodigester to properly handle excreta and count on sustainable development.
