Evaluación de la planta de tratamiento de aguas residuales de la comunidad Valle Hermoso Artezón perteneciente al cantón San Pedro de Pelileo, provincia de Tungurahua

Abstract

The Wastewater Treatment Plant from Valle Hermoso Artezón community, surrounded by houses and extensive crop fields, has generated inconvenience to residents due to bad odors and lack of maintenance. Although the plant has shown favorable efficiency in its treatment process, its maintenance has been found to be insufficient. The study of the plant began with the collection of data corresponding to its components (Distributor Tank, Catchment Tank, Septic Tank, Biological Filter, Descending Filter, Sludge Drying Bed). The maximum flows of wastewater were estimated both at the entrance and at the exit of the plant. A composite sample of the influent and the effluent was made, which was tested in the quality control laboratory of the EMAPA Public Company, which allowed determining the pollutant load treated in the plant and was compared with the parameters established in the TULSMA 2015 standard. The analysis of the wastewater treatment procedure at the plant confirmed that it was operating correctly, since the efficiency obtained for each parameter analyzed in the laboratory was positive, indicating that no changes should be made to its treatment train. Additionally, an operation and maintenance plan was established to improve various aspects of the plant, the construction of a cover for the sludge drying bed was proposed, with the aim of guaranteeing its function of dehydrating the sludge that is discharged from the Septic Tank.
