Evaluación de la planta de tratamiento de aguas residuales del sector Jesús del Gran Poder de la parroquia Píllaro del cantón Santiago de Píllaro de la provincia de Tungurahua

Abstract

Currently, one of the most important environmental problems and of great interest to society is wastewater without prior or adequate treatment, therefore, an experimental work was carried out to evaluate and determine whether the Wastewater Treatment Plant of the sector under study works optimally and meets the minimum parameters for removal of pollutants and pathogens. The evaluation of the WWTP was carried out with a field survey, in which the maximum inlet and outlet flow rates were determined, resulting in 1.27 lts/sec in the influent and 1.26 lts/sec in the effluent, in addition, the different hydraulic units were measured and diagnosed, responding correctly and complying with the parameters established in the design guides and manuals. With the results obtained, the physicochemical characteristics of the wastewater were analyzed, where it was verified that the basic parameters: pH, COD, BOD5, Suspended Solids and Total Solids comply with the established in the regulations, however there is the presence of ammonia nitrogen and phosphate that are not being removed, for which it is recommended the implementation of the species of Lechuguín "Eichhornia carssipes" in one of the upflow anaerobic filters, with the purpose of absorbing the excess nutrients through the roots of these plants. Finally, the use of an operation and maintenance plan and the implementation of a metal cover are recommended in order to better maintain the operation of the PTAR.
