Diseño y construcción de un biodigestor hindú anaerobio en la finca “Los Cuencanos” de la Parroquia García Moreno

Abstract

This investigation aims to design and construct a Hindu biodigestor to produce biogas by means of the homogenous-cattle and pig manure characterization using the laboratory physicalchemical analysis for Los Cuencanos farm at Garcia Moreno Parish, Province of Orellana. Two

prototypes

were carried whereby the mixture rate between the two types of manure and 1:0.75 water manure rate were determined. A 6 L plastic container, a xxiv

1 / 2 inch hose and a inch shutoff

valve were used. From the initial results, the approximate biogas production value was known. The engineering formula helped to design the required biodigestor. Its structures are divided into two: 1) concrete was 1.93 m high and 1.86 m wide, an input box, a Biol output box, a mud box and 2) a stainless steel part (gas meter) 1.54 m high and 1.28 m wide to store biogas up to 1.73 m 3 with retaining time of 28 days. The total solid concentration of 19%, C/N rate 11.57%, pH 7 and the substrate temperature 26°C were determined with the pretreatment analysis. Determining 7 day production intervals with the water displacement method and producing 0.0 285 m 3 at 2 2°C in 14 days, 0.038 m 3 at 26°C in 14 days, 0.053 2 m of biogas at 34 C in 21 days and 0.06 27 m 3 at 37 C in 28 days of retention and 74% of efficiency were gotten. It is concluded that the biodigestor produces 0.2 m 3 of biogas/day, that is, the energetic demand for the farm is met. It is recommended to construct this system since it is a good technological alternative to produce biogas and to handle farm animal-raising waste.
