Evaluación de la planta de tratamiento de aguas residuales de la ciudad de Babahoyo.

Abstract

The present study was performed in order to analyze and evaluate the Wastewater Treatment Plant of the city of Babahoyo to determine the state in which it is found and whether the treated water discharged to the Babahoyo River complies with the TULSMA standards. The project focused on three important points: the arrival of waste water from the city to the plant, th e exit of the reactors (UASB) and the exit of the stabilization lagoons. After the field work was prepared, the charts were prepared to establish the efficiency of the plant units and if they were downloading the water treated with the permissible limits of the standard. From the results obtained for each parameter, it was verified that they are under the maximum permissible limit indicated in the TULSMA, this does not mean that the operation and maintenance of the sewage treatment plant of the city of Babahoyo is operating in an optimal way. When calculating the efficiencies with the obtained results it was established that the UASB has a low efficiency in the removal of the selected parameters, while the gaps have a high efficiency. The poor performance of the UASB is due to inadequate operation of the plant, since they ignite the screws of Archimedes in a discontinuous way. In addition, the infrastructure is in poor condition, its metal parts are corrosion and concrete has a layer of mold.
