Abstract
Se determinó la calidad sanitaria, nitrógeno amoniacal, fósforo y potasio de un
biofertilizante obtenido utilizando un biorreactor anaerobio semicontinuo modelo hindú.
Se preparó un inóculo fermentativo de bovino y como sustrato guano de isla. Este
biofertilizante se obtuvo a los 7, 14, 21 y 28 días, se observó un incremento
significativo de 42,42% ( NH4
+), 8,9% (P2O5) y 30,5% (K2O), siendo la temperatura
promedio en el biorreactor de 22 °C. Se estimó una eficiencia de remoción de 82,1 %
para la DQO y 95,4% para la DBO5 para un tiempo de 28 días, pH de 6,78 y 7,85, de
entrada y salida en promedio respectivamente. Se obtuvo una remoción del 99,9% de
coliformes totales en el tiempo máximo de 28 días.
The sanitary quality, ammoniacal nitrogen, phosphorus and potassium of a biofertilizer obtained using a semi-continuous anaerobic bioreactor, the Indian model, were determined. A bovine fermentative inoculum was prepared and island guano as substrate. This biofertilizer was obtained at 7, 14, 21 and 28 days, a significant increase of 42,42% ( NH4 +), 8,9% (P2O5) and 30,5% (K2O) was observed, with the average temperature in the bioreactor being 22 °C. The removal efficiency of 82,1% for COD and 95,4% for BOD5 was estimated for a time of 28 days, pH of 6,78 and 7,85, and input and output on average, respectively. Removal of 99,9% of total coliforms was obtained in the maximum time of 28 days.
