Evaluación de la eficiencia de estabilización de los lodos obtenidos a partir de la operación del sistema de Tratamiento Primario Químicamente Mejorado (CEPT), mediante la aplicación del método de digestión anaeróbica de alta tasa.

Abstract

The purpose of this titling work was to evaluate the efficiency of the high-rate digester through the application of chemically improved primary treatment (CEPT) in the domestic wastewater of the city of Guayaquil, within the analyzes performed the removal efficiencies are presented reported biochemical oxygen demand (BOD) and chemical oxygen demand (COD), results of the implementation of chemically improved primary treatment. For the collection of the samples a pilot plant was used, which consisted of pumping the domestic wastewater to the pilot plant, the tributary reaches the rapid mixing tank where the ferric chloride and polymer are dosed, then it passes to the coagulation tank and flocculation and finally passes to the clarifier tank, once the sample is obtained it is stored in a high-rate digester, then the efficiencies obtained for the parameters of biochemical oxygen demand (BOD) and chemical oxygen demand are compared. (COD). Likewise, a comparative analysis with a previous work of anaerobic digestion of low rate.
