Abstract

The work was carried out with the objective of determining the pig effluents properties (digestate) as organic fertilizer; as well as the possibility of their decontamination. The effluents was taken, in three  anaerobic digesters located in the central region of Cuba (Sancti Spíritus and Villa Clara); as well as four samples in the lagoon of oxidation of the pig facility of the Central University "Marta Abreu" of Las Villas. In these last ones the decontaminate effect of a bio-product was proven (CBQ-BioRem) with different dilution dose (1/10, 1/100, 1/1000 and 1/10000). In the effluents, they were determined: physical-chemical and microbiological properties, previous and later to their step for bio-filters; it was valued their effect like organic bio fertilizers, the effluents of the biodigesters were diluted in water (50%, 75% and 90%). It took like indicative cultivation the corn (Zea mays), being evaluated their Morphophysiological parameters; in the soil samples. In most of the effluents, the microbial load could be reduced using bio filters and the bio-product CBQ-BioRem, obtaining values below the Cuban norm. The analysis of the effluents like bio fertilizers showed a positive effect in the dilute ones to 50%, 75% and 90% in water, reaching germination percent of (100%). In the blended effluents with the bio-product, alone a good germinate result was reached in the dilute effluent to 10% achieving (100%) of germination, being the other dilutions investigated below the control.

Keywords: Bio filters, pig efluentes, decontaminate effect, % germination
