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

Abstract

The main objective of this research is to determine if the plant is operating optimally. The evaluation of the community WWTP began with the gathering of information, a field investigation which was used to take dimensions, inflow flows to determine the design flow to be used. Wastewater samples were also taken, which were analyzed by an accredited laboratory and whose results were compared with the limit parameters established by the TULSMA 2015 regulation for wastewater discharges into freshwater bodies, where it was found that the parameter oils and fats does not comply with the standards, which showed that the WWTP is not working properly. Finally, a diagnosis was made of each of the current treatment processes, where it was found that some of its structures, such as the septic tank, do not meet the criteria and recommendations established in the design manuals. For the reasons mentioned before, it is proposed to incorporate a new treatment process (fat trap) to treat the high value of that parameter. Also, to carry out a structure redesigns that now, currently do not comply with the standards, and finally to incorporate an operation and maintenance plan to ensure the correct operation of the WWTP through the time.
