Abstract
Este proyecto se basa en el diseño y construcción de un biodigestor anaerobio de laboratorio, así como su puesta en marcha y aplicación práctica por medio de la realización de un experimento, en el que se analizará la producción de biogás a diferentes temperaturas de digestión, en concreto a 25ºC, 30ºC y 35ºC. De este modo se ha determinado la influencia de la temperatura en la calidad y cantidad del biogás producido, así como su influencia en otros parámetros. Para ello se han realizado una serie de 4 experimentos en los que se han controlado parámetros como el pH, la DQO, los contenidos de fósforo y nitrógeno y volumen de biogás producido, entre otros. Este caso práctico servirá como prueba del correcto funcionamiento del biodigestor, y a su vez servirá en sí mismo como un estudio sobre la producción de biogás en este tipo de digestores con diferentes condiciones de temperatura. De este modo, el proyecto podrá servir como guía para la construcción de biodigestores similares, así como manual para su uso correcto, con recomendaciones y consejos prácticos. Además, las conclusiones obtenidas en los experimentos, servirán para posteriores ensayos. Por otro lado se plantean posibles experimentos y aplicaciones futuras, sirviendo de este modo el biodigestor no solo para la realización de este proyecto, sino para posteriores usos y aplicaciones del mismo. _____________________________________________________________________________________________________________________
This project is based on the design and construction of a laboratory anaerobic digester and its implementation and practical application by conducting an experiment which analyzed the production of biogas during the digestion at different temperatures in concrete at 25°C, 30ºC and 35ºC. This has determined the influence of temperature on the quality and quantity of produced biogas, and its influence on other parameters. For this have been made a series of 4 experiments in which several parameters as pH, COD, phosphorus and nitrogen content and volume of biogas produced, among others, were monitored. This case study will serve as proof of proper functioning of the digester, and in turn serve itself as a study of the production of biogas digesters at different temperatures conditions. Thereby, the project will serve as a guide for building similar digesters, as well as a manual for proper use, with recommendations and tips. Furthermore, the conclusions obtained in the experiments, will serve for further testing. On the other hand, are present possible future experiments and applications, so serving not only the digester for this project but for future uses and applications of it.
