Producción De Biogás Mediante Codigestión Anaerobia De Excretas De Borrego Y Rumen Adicionadas Con Lodos Procedentes De Una Planta De Aguas Residuales

Abstract: Palabras clave: biodigestor, excreta, metano, residuos RESUMENHoy en día se necesitan nuevas fuentes de producción de energía. Además, hay un incremento de los residuos agrícolas que representan un problema ambiental. El propósito del presente estudio fue comparar la digestión anaerobia de excretas de borrego con la codigestión anaerobia de excretas de borrego más lodos de aguas residuales y la codigestión anaerobia de excretas de borrego más rumen. Los resultados mostraron que el tratamiento T1 (excretas de b… Show more

“…However, the highest methane production and proportion methane by gas produced in the digester with sheep excreta was possibly due to the fact that the nature of the excrement (encapsulated) conserved better the methane producing microorganisms with respect to the manure of cattle, these microorganisms (methanogenic Archaea) that coexist in the rumen are responsible for producing about 60% enteric methane in ruminants, and that being found in the manure of ruminants could favor the production of methane under conditions of anaerobic fermentation in biodigesters (Alvarez and Lidén, 2009) in relation to other excreta, something observed in this investigation (Table 1). These results are consistent with those reported by Sarabia Méndez et al (2017).…”

“…Usualmente estos residuos se almacenan en pilas cerca de los centros de beneficio y dan origen a malos olores, la contaminación del manto freático y la eutrofización de ríos y lagunas donde son vertidos. Sarabia et al (2017) plantean que la digestión anaerobia es una tecnología con la que se alcanza la disminución de la carga contaminante del residual y la recuperación de energía. Muchos de los residuos agroindustriales son candidatos para la digestión anaerobia por su alto contenido de materia fácilmente biodegradable.…”
