Obtención de biol a partir de desechos generados en el Mercado Mayorista y en el Camal de Riobamba usando un consorcio microbiano como acelerador.

Abstract

The objective of this study was to produce biol on a laboratory scale, from wastes generated in the Empresa Pública Municipal Mercado de Productores Agrícolas (EP EMMPA) and in Camal Municipal of Riobamba using a microbial consortium as an accelerator. For this purpose, a consortium of Lactic Acid Bacteria (LAB), pure milk and whey, were added to three organic matter mixtures of the same type, respectively, preparing the formulas (T1, T2, T3) respectively, which were subjected to a phase of anaerobic decomposition, with monitoring of PH and temperature and its effect against the T0 control was evaluated, according to some of the physicochemical and microbiological changes, as well as the duration of the process and the obtained yield. The results were analyzed statistically under a completely randomized block design, with analysis of variance and separation of means by the Duncan test. Under the study conditions, the T3 treatment was identified as the best, with significant differences (p> o, OI) and higher in relation to T0, T1 and T2 in most tests applied to the effluents of the biodigesters (0.2579). % P2O5, 0.3440% K2O, 1.1978% MgO, 0.0187% Fe, 3.30% MO), and lower by 0.1965% CaO; 19 300 mg / L BOD; 46 400 mg / L DQO), without d differences in TN (0.26%) and CE (2740 ps / cm). Total and fecal coliforms were absent, the pH oscillated in the range of neutrality and the temperature was mesophilic. For T3 a yield of 67.5% was achieved in a bioprocess that lasted 36 days. A biol that keeps the balance of the carbon and nitrogen matter and is controlled in its functional characteristics guarantees its use in food crops.
