Evaluación de un reactor de biopelícula aplicado al tratamiento de efluentes del camal municipal de pasaje - El Oro

Abstract

Water being one of the vital points for human beings, forestation, however, the contamination generated by various means is focused on damaging this supply, the municipal slaughterhouse produces this type of waste generated by the slaughter of cattle and pig species without the application of a proper remediation treatment. Here was born the problem with the objective of giving solution this experimentation was to design an aerobic bioreactor system for the removal of pollutant load in the municipal slaughterhouse of the city of Pasaje, El Oro which was applied a qualitative and quantitative study applying three experimental equipment of 10L of volume, each reactor with three different volumetric organic loads (VOL) of 3, 5 and 8 respectively, obtaining as hydraulic retention time (HRT) the values of 19.58 h, 11.75 h and 7.34h for the process, analyzing the necessary operating parameters. Daily sampling was applied before, during and after the contaminated solution passage, considering the effectiveness of the reactors with moving bed biofilm reactor (MBBR) technology, observing the growth kinetics inside the biomass carriers, and observing their efficiency in wastewater remediation. The results indicate that reactor 3, with VOL = 3 kg COD/m3-day presented higher efficiency in pollutant load removal, reaching 86.8% COD removal, being a data of 375 mg/L COD, showing that it is an acceptable value for release into the sewage system according to the environmental quality and effluent discharge standard of Annex 1 of Book VI of the TULSMA detailing a maximum permissible limit of 500 mg/L, avoiding the exuberant contamination in these systems, concluding that the treatments have obtained different values and therefore, by simple analysis, the adequate one was obtained for its implementation, confirming with bibliographies that the lower the VOL, the better the percentage of removal.
