| Spanish abstract | El trabajo se desarrolló en la provincia Cienfuegos, a través de un diseño observacional, transversal en el mes julio de 2015, se compararon 6 biodi-gestores de Cúpula Fija y 6 de geomembrana de PVC, ambos de capacidad de 10 m3, establecidos en unidades porcinas de ceba con una capacidad de 50 – 100 animales, para determinar la eficien-cia que mostraban en los sistemas de producción porcina no especializada. Para ello se determinaron indicadores de operación de los biodigestores pH, CE, DQO, DBO5, SS, STV. Se alcanzaron valores de pH de 7,25, CE de 4070 (μ S/cm), DQO de 3833 mg/l, DBO5, 1825,3 mg/l, SS de 78.3 ml/l para los biodigestores de Cúpula Fija y 7,21, 4072 (μ S/cm), 1890 mg/L, 1009.2 mg/l, SS de 76,6 ml/l para los biodigestores de geomembrana respectivamente. No se obtuvieron diferencias significativas entre los de efluentes de los tipos de biodigestores, excepto la DQO. Se obtuvieron porcentajes de remoción de DQO 51,2 y 64,5, DBO5 58,8 y 61,6, SS 57,6 y 55,0 STV 57,0 y 62,0 para los biodigestores de Cúpula Fija y de Geomembrana, respectivamente.Se con-cluyó que los biodigestores muestran baja eficiencia en los sistemas de producción porcina no especiali-zada de la provincia Cienfuegos |
| English abstract | The work was carried out in the province of Cienfuegos, through an observational design, trans-versal in the month of July 2015, 6 biodigesters of fixed dome and 6 of geomembrane of PVC, both with capacity of 10 m3, established in porcine units of Strain with a capacity of 50 - 100 animals, to de-termine the efficiency they showed in non-speciali-zed porcine production systems. For this purpose, the operating indicators of the biodigesters pH, CE, COD, BOD5, SS, STV were determined. PH values of 7.25, CE of 4070 (μ S / cm), COD of 3833 mg / l, BOD5, 1825.3 mg / l, SS of 78.3 ml / l were reached for the Fixed Dome biodigesters and 7 , 21, 4072 (μ S / cm), 1890 mg / L, 1009.2 mg / l, SS of 76.6 ml / l for the geomembrane biodigesters respectively. There were no significant differences between the effluents of the biodigester types, except COD. Percentages of removal of COD 51.2 and 64.5, BOD5 58.8 and 61.6, SS 57.6 and 55.0 STV 57.0 and 62.0 were ob-tained for fixed-dome and geomembrane biodiges-ters, Respectively. It was concluded that biodiges-tors show low efficiency in the non-specialized pig production systems of Cienfuegos province |
