Evaluación de la planta de tratamiento de aguas residuales de la comunidad LLimpe Chico, cantón Quero, provincia de Tungurahua

Abstract

The main objective of this research is to evaluate the operation of the WWTP based on the analysis of the residual water and the operation of each of the components that are part of the treatment train. To carry out the evaluation of the WWTP, it began with a survey and collection of information on the current state, based on field work, the incoming and outgoing flows were determined, with which it was possible to know the peak hours where the WWTP receives greater and lesser amount of pollutants, residual water samples were also taken for evaluation and to determine the load of waste that enters and leaves the WWTP to make a comparison with the TULSMA 2015 standard based on the discharge limits to a body of fresh water. Each component (distributed tank, septic tank, sludge drying bed and ascending biological filter) that intervenes in the treatment of residual water was evaluated based on the standards in force today, where it was known that these components remove approximately 30 percent of the pollutants, for which a new treatment train was incorporated (Screening, Desander, Grease Trap, Septic Tank, Sludge Drying Bed and Upward Biological Filter) and an operation and maintenance plan so that pollutants from the residual water can be removed by 90 percent.
