Modelación y optimización del reactor biológico de la planta de tratamiento de aguas residuales de la ciudad de Ambato.

Abstract

The objective of this research was to evaluate the removal of organic matter from the biological reactor of the Wastewater Treatment Plant of the city of Ambato in Ecuador. When the base line of the current operation was raised the removal of organic matter was forty-eight percent. An evaluation of the West Lab software specific kit for wastewater modeling was performed. It was determined that the amount of dissolved oxygen, the retention time of the hydraulic, and the amount of biomes were the variables that directly affected the operation of the biological reactor. For the simulations, three scenarios were evaluated by varying the flow, oxygen, and the amount of solids. For all other variables, the results found a seventy-six percent removal of organic matter. An analysis of the best alternatives for optimization obtained an eighty-five percent rate of removal of organic matter which exceeded what was obtained in the simulation. Finally, the results of the discharge into the river with Table 9 of the TULSMA confirmed compliance with the Environmental Legal Regulations which resulted in a recommendation to perform the simulation for the sludge line of the plant facility.
