Desenvolvimento de um sistema biodigestor para obtenção de biogás durante o inverno na região de Lages-SC.

Abstract

The objective of this project was to develop a biodigestor system for the production of biogas during the winter in the region of Lages, SC. For this, was constructed a biodigestor with total volume of 100 L, supplied with swine wastes in termination phase, without dilution in water, in a total of 80 L of useful volume of substratum. The biodigestor was displayed, at a first moment, the average temperatures that had varied of 24 to 35°C, using itself for such end, a solar collector. To follow, the biodigestor was displayed to a fixed temperature of 35° C, through electric heating. It did not have agitation of the substratum. The analyses of the pr oduction of biogas and the efficiency of the heating system had been carried through in periods of 15 days. The results had demonstrated that the biodigestor reached its bigger level of production of biogas (65,25 L) in the temperature of 35°C with the system of ele ctric heating. With the solar collector the production of biogas arrives 69% of the produced one with the electrical system (45,10 L).
