Evaluación de la planta de tratamiento de aguas residuales comunidad Pilco parroquia Rumipamba, cantón Quero, provincia de Tungurahua

Abstract

The present evaluation project was carried out to the Wastewater Treatment Plant of the sector under study, built in 2015, with the objective of verifying its efficient, adequate and quality operation in the treatment of wastewater. The technical-theoretical verification of the dimensions and physical elements of each of the units that make up the WWTP was performed, finding oversizing in the septic tank. With respect to the decontamination train, simple and composite samples were taken in situ to determine the physicochemical aspects of the wastewater entering and leaving the WWTP, these being indicators of the percentage of pollutant removal efficiency, the following being the highest pollutant load and non-compliance with the TULSMA 2015 regulations: BOD5, COD, Ammonia Nitrogen and Sulfides. In the land where the WWTP is located, an improvement plan was implemented for the conservation of the treatment units with maintenance, cleaning, and safety elements such as fences and signage. In addition, the construction of a metal structure cover is proposed to improve the processes in the sludge drying bed. In conclusion, to improve the efficiency of the Pilco community’s WWTP, it is necessary to carry out adequate maintenance, with the necessary frequency, on each of the treatment units, with the septic tank being the one most in need of control because it is oversized and poorly operated. This produces high emissions of pollutants into the water and the environment.
