Evaluación de la planta de tratamiento de aguas residuales de la comunidad Zona Libre, cantón Quero, provincia de Tungurahua

Abstract

In the present experimental work, its main objective is to evaluate the operation and functioning of the unit processes of the Wastewater Treatment Plant of the Zona Libre community, which serves approximately 295 people; The purpose of the study is to determine whether it actually complies with the parameters required by current environmental regulations (TULSMA). In the research, gauges were first developed for 7 consecutive days to determine the current flow into and out of the plant; consecutively, wastewater samples were sent to the laboratory to analyze its physical and chemical characteristics. The evaluation of the plant consisted in the dimensioning of the treatment units until the present year (2021), for this the data obtained in the field and laboratory were used, concluding that the current geometry in each treatment unit is similar to that obtained theoretically. With the exception of the FAFA, which does not have the adequate volume for the filter medium to reduce the pollutant load of the wastewater. In addition, the WWTP in general achieves low removal efficiency percentages: BOD with 1.93 percent and COD with 0.47 percent Once all the aforementioned information has been processed, it is proposed to incorporate a new treatment process and an operation and maintenance manual, which aims to contribute to the improvement of the operation of the units.
