Evaluación de la planta de tratamiento de aguas residuales del sector Santa Teresita de la parroquia Ciudad Nueva perteneciente al cantón Santiago de Píllaro, provincia de Tungurahua

Abstract

The purpose of this work was to evaluate the current operation of the wastewater treatment plant in the community of Santa Teresita, in the canton of Píllaro, province of Tungurahua, thus improving the quality of life of the inhabitants of the area. The first step was to collect information on the operation of the treatment plant, then the flow rates of the influent and effluent were measured using the volumetric method for thirty consecutive days to reduce the existing error according to the statistical analysis established for the representative sample of the sector, which allowed the maximum hourly flow rate to be determined for the diagnosis of the WWTP. Once the day with the highest flow rate was determined, samples of the influent and effluent wastewater were taken to carry out the pollutant load analysis at the UNACH Laboratory, whose results for COD is 137 mg/l and BOD5 is 70 mg/l, which showed that the WWTP units: desander, upflow anaerobic reactor, upflow anaerobic filter and sludge drying bed comply with the maximum parameters established in the Unified Text of Secondary Legislation of the Ministry of Environment (TULSMA, Book VI, Annex 1 - Table 9). Once the current operation of the WWTP was evaluated, an operation and management plan for the units of the WWTP was made, establishing measures that will improve and increase its useful life, providing plans and budget for its execution.
