Abstract
El presente trabajo de investigación evalúa la eficiencia de diferentes densidades celulares de Bacillus subtilis en el tratamiento de aguas residuales del camal municipal de La Esperanza. La investigación es de tipo experimental aplicativa, prospectiva y transversal, utilizando un diseño experimental puro con dos grupos aleatorizados y pruebas pre y post tratamiento, se analizaron dos densidades celulares de Bacillus subtilis: 0.5 y 1.5, la población de estudio fue el volumen diario de agua residual generado por el matadero de La Esperanza, que asciende a 34.5 metros cúbicos por día, la muestra recolectada intencionalmente en momentos de alta contaminación orgánica, consistió en 10 litros de agua de puntos específicos del camal. Los resultados demostraron que el tratamiento con Bacillus subtilis redujo significativamente los niveles de contaminación, alcanzando valores dentro de los límites establecidos por el Decreto Supremo N° 010-2019-VIVIENDA. En particular, la densidad celular de 1.5 mostró mejores porcentajes de biorremediación concluyendo que la densidad celular de Bacillus subtilis es efectiva para tratar aguas residuales del camal municipal de La Esperanza, cumpliendo con los estándares legales y logrando una mayor eficiencia con la densidad de 1.5.
The present research work evaluates the efficiency of different cell densities of Bacillus subtilis in the treatment of wastewater from the La Esperanza municipal sewer. The research is of an applicative, prospective and transversal experimental type, using a pure experimental design with two randomized groups and pre and post treatment tests, two cell densities of Bacillus subtilis were analyzed: 0.5 and 1.5, the study population was the daily volume of residual water generated by the La Esperanza slaughterhouse, which amounts to 34.5 cubic meters per day. The sample intentionally collected at times of high organic contamination, consisted of 10 liters of water from specific points in the slaughterhouse. The results demonstrated that treatment with Bacillus subtilis significantly reduced pollution levels, reaching values within the limits established by Supreme Decree No. 010-2019-HOUSING. In particular, the cell density of 1.5 showed better bioremediation percentages, concluding that the cell density of Bacillus subtilis is effective for treating wastewater from the La Esperanza municipal wastewater, complying with legal standards and achieving greater efficiency with the density of 1.5.
