Aprovechamiento de los residuos sólidos producidos por el ganado, para la producción de biogás y fertilizantes en la estación experimental Tunshi.

Abstract

The present work had the purpose of studying the solid waste produced by cattle through the design and implementation of a tubular biodigester in the Tunshi experimental station located in the Licto parish, in this way, it was decided to take several scientific documents as a reference in order to adapt it to the current situation within the study area, in turn, the analysis of existing species in the study area was carried out, as well as the necessary demand for biogas to determine various parameters such as: daily load, retention time, size of the plastic, the design of the trench to meet the required demand, thus having a dimensioning of the area suitable for the requested requirement, installing it near the place to be used in a water heater and to be able to load the reactor. At the same time, the physicochemical analysis of its variables was carried out; For this, the biodigester was monitored for 40 days, analyzing the ambient temperature, temperature inside the greenhouse, pH, color of the biol, percentage of dry matter and likewise the percentage of nitrogen, phosphorus and potassium. With the data obtained, it was determined that the daily load necessary to solve 1300lt of necessary biogas is 34.21kg of manure with 102.63lt of water, having a volume of 5.47m3 and an average temperature of 29oC, in turn it was obtained 0.18%, 0.36%, 0.22% of NPK respectively and a pH of 6.64 optimal for the use of fertilizer in crops. It is concluded that the use of a biodigester can help us to reuse the waste produced by livestock and generate biol and biogas, however, it is advisable to carry out detailed field studies before installing it.
