Resumen
En este proyecto investigativo, el objetivo principal es la evaluación de la concentración de DBO5 y DQO en los efluentes de la PTARD de la Urbanización Villa Club, y a su vez indirectamente mediremos la eficiencia de los tratamientos biológicos que se aplican en este sistema.
Para llegar a esta evaluación, previamente realizaremos aforos del caudal, caracterización de aguas residuales que ingresan a la planta, del efluente tratado, y la evaluación del funcionamiento de las diferentes etapas de tratamiento del sistema estudiado.
Las etapas de la PTARD incluyen un desbaste, un ecualizador, reactor biológico aireado, digestor de lodos, clarificadores, un filtro de grava ascendente y un sistema de desinfección UV.
Al conocer cada una de las fases de la PTARD, se proceden a desarrollar ensayos de laboratorio de los caudales de entrada y salida, a través de un muestreo simple, que se efectuó cumpliendo la Norma Técnica Ecuatoriana, y en cuatro días diferentes.
En el análisis del efluente tratado observamos que la eficiencia del sistema es óptima, con un promedio de 92.87% y 90.92% de remoción de DBO5 y de DQO respectivamente; además la media aritmética de los valores de concentración de DBO5 es 18.25 mg/l y de DQO es 44.75 mg/l, cumpliendo así con las expectativas planteadas en el diseño inicial o del efluente proyectado.
In this research project, the main objective is evaluating the concentration of BOD5 and COD in the PTARD effluents in Villa Club Urbanization, and indirectly we will measure the biological treatments efficiency we can found in this system. To arrive at this evaluation, we will previously carry out flow capacity, characterization of wastewater entering to the plant, from the treated effluent, and the evaluation of the operation of the different treatment stages of the studied system. The stages of the PTARD include a roughing, an equalizer, aerated biological reactor, sludge digester, clarifiers, an ascending gravel filter and a UV disinfection system. Knowing each PTARD stages, we proceed to develop laboratory tests of the inflow and outflow, through a simple sampling, which is carried out in compliance with the Ecuadorian Technical Standard in four different days. In our treated effluent analysis we could observe that the efficiency of the system is optimal, with an average of 92.87% and 90.92% removal of BOD5 and COD respectively; In addition, the arithmetic average of the concentration values of BOD5 is 18.25 mg/l and COD is 44.75 mg/l, finally our results meet the expectations set in the initial design or the projected effluent.
