Diseño de una planta de tratamiento de aguas residuales para el laboratorio de control de calidad de la EP. EMAPA-G, Cantón Guaranda, Provincia de Bolívar

Abstract

Design of Treatment Plant Wastewater laboratory Qualily Control in canton Guaranda, Bolivar province, to reduce pollution of the affected area and improve the quality of life of the inhabitants of the area was performed. It began with the measurement of effluent flow laboratory, the volumetric method is used, and the flow rate was measured every 10 minutes from 8:00 until 18:00, for a week from Monday to Friday. 5 wastewater samples were taken, the sample compound was used. HACH methods for characterization and empirical laboratory methods were used. For dosing of chemical jar testing was performed. For the design engineering calculations and design criteria they were used. The results of monitoring the flow noted that is variable and small flow. The parameters resulting from the characterization were compared with the maximum permissible limits of Table 12, Annex 1 of book VI, of the regulations TULSMA, which did not meet the standard were: total dissolved solids, fluorides, cobalt, lead, silver, barium, COD, BOD and fecal coliforms. Grids, storage tank and coagulation, horizontal flocculator, high rate sedimentation, anaerobic filter up loose, tank disinfection and final storage tank: the treatment plant was sized composed. They were considered as the main pollutants to COD and BOD, the theoretical yield of the plant for COD removal was 93%, with a final concentration of 57.58 mg/L. The theoretical yield of the plant for BOD, was 93.1%, with a final concentration of 24. 34 mg/L. Both values are below the limit required by law. It is recommended that the laboratory personnel, use of treated water for washing facilities.
