Evaluación del funcionamiento de la planta de tratamiento de aguas residuales del sector Cardo Santo de la parroquia San Andrés perteneciente al cantón Santiago de Píllaro, provincia de Tungurahua

Abstract

An experimental work was carried out with the objective of determining if the Wastewater Treatment Plant (WWTP) is working properly or if its efficiency in the removal of pollutants has decreased throughout its useful life. The evaluation of the WWTP began with the collection of on-site information on the dimensions of the decontamination hydraulic units and the plant's inlet and outlet flow rates. Wastewater samples were taken at the inlet and outlet of the WWTP and a characterization analysis was performed in an authorized laboratory. The results obtained were compared with the TULSMA 2015 regulations, revealing that the levels of pH, COD, BOD5, Suspended Solids and Total Solids are under the maximum limits allowed for wastewater discharge into freshwater bodies. Subsequently, each hydraulic unit was diagnosed, determining that they comply with the parameters established in the design guidelines and manuals for wastewater treatment plants. Finally, it is suggested to implement an operation and maintenance plan to maintain and optimize the correct operation of the WWTP, which includes a cover for each sludge drying bed in order to increase its dehydration and final disposal of the residual sludge, in addition, it includes cleaning and care measures for each hydraulic decontamination unit.
