Depuración anaerobia de aguas residuales de granjas porcinas. Ensayos a escala de laboratorio

Abstract

Se estudia la viabilidad de un tratamiento biológico integral de los purines de una granja de cerdos. Previamente, a escala de laboratorio se realiza un estudio anaerobio de la biodegradabilidad de dichas aguas residuales, empleándose soportes micronizados para la retención de los microorganismos en régimen discontinuo a 35ºC, en un intervalo de carga orgánica entre 0,2 y 2,2 g/l, como DQO. La máxima velocidad de producción de metano se obtiene en las primeras 24 horas. El valor medio más elevado del rendimiento en la depuración (% DQO consumida) lo presentan los reactores con saponita, sepiolita natural y sepiolita calcinada.

The viability of an integral biological treatment for the swine wastewater purification in a piggery farm, was studied. Previously, at a laboratory scale, the anaerobic biodegradability of this wastewater was analyzed, using different clayey supports to immobilize the microorganisms in batch regime, at 35ºC, with an organic load ranged from 0,2 to 2,2 g COD/l.
