Resumen

El rápido crecimiento poblacional en el sur de Quito ha incrementado la producción de aguas residuales que generan descargas en cuerpos hídricos y afectan la calidad del agua. En este contexto, caracterizar las aguas residuales es crucial para la toma de decisiones operativas confiables. Esta investigación evalúa el biorreactor de PTAR Quitumbe en relación al fraccionamiento de DQO y nitrógeno, tomando en cuenta la edad del lodo como variable a controlar. Se muestrearon aguas residuales en puntos de entrada y salida del biorreactor, em-pleando métodos fisicoquímicos de fraccionamiento de DQO. Los resultados indican predominancia de DQO lentamente biodegradable (XS) y eliminaciones del 95% en DQO biodegradable y 93% en nitrógeno amoniacal, demostrando la capacidad de biodegradación. Se confirmó la desnitrificación incompleta y un tiempo de reten-ción celular de 20 días. Este estudio proporciona una base sólida para mejorar la gestión operativa de la PTAR Quitumbe.
