Evaluación de la planta de tratamiento de aguas residuales de la parroquia Quisapincha, cantón Ambato, provincia de Tungurahua

Abstract

In order to determine whether the wastewater treatment plant (WWTP) of the Quisapincha parish is currently working properly or whether its efficiency in the removal of pollutants has been reduced over the years, a survey of information was carried out to measure the units of the treatment train, the volumetric capacity of the plant's inlet and outlet tanks, the analysis of physical-chemical parameters in the laboratory and the technical diagnosis of each process. The operation of the plant's unit processes was evaluated, which are: Screening, sedimentation and flow sharing tank, biological filter of “lechuguines”, upflow anaerobic filter and sludge drying tank, demonstrating that they work correctly in comparison with guides and manuals for the design of treatment plants; and the outflow affluent complies with the TULSMA standard for discharges into freshwater bodies. After analyzing the information, it was concluded that it is not necessary to implement new processes within the WWTP; however, recommendations were proposed for the system to work better.
