Influencia de la separación de agua residual porcina en fracciones sólida y líquida, en la producción de metano con Iodo anaerobio granular y disperso

Abstract

Las estrategias actuales de tratamiento de efluentes porcinos en México son en muchos casos poco eficientes, que se traduce en la descarga de aguas tratadas parcialmente y no tratadas, así como el desaprovechamiento de un recurso energético. El objetivo de este estudio fue evaluar el impacto de la separación sólida-líquida del agua residual porcina sobre la producción de metano, utilizando lodo granular (LG) y lodo disperso (LD), bajo tres concentraciones. La concentración de DQO en el efluente crudo (EC) fue de 13,640 mg/L, con 69 % correspondiente a la fracción sólida (FS) y el resto para la fracción líquida (FL). Los resultados indican que los cultivos con la FS produjeron una mayor cantidad de metano, incrementándose 1.47, 1.31 y 1.22 veces en comparación al EC, para las concentraciones de 3, 6 y 9 g SSV/L de LD. La estrategia de separación sólida-líquida resultó en incrementos en la producción de metano, evidenciado porque la suma del metano acumulado por la FS y FL fue entre 2.14 y 2.28 veces mayor que la cantidad obtenida por el EC. La aplicación de procesos anaerobios para tratar residuos sólidos y líquidos permitirá recuperar de manera más eficiente la energía a partir de la transformación de la materia orgánica a metano.
