Diseño de una Planta de Tratamiento de Aguas Residuales para el cantón Chambo – provincia de Chimborazo.

Abstract

System treatment plant wastewater was designed in Waste Water in the discharge zone, Jesus del Gran Poder, Chambo canton, Chimborazo province, using basic materials for sample collection and measurement of flows in the discharge zone. Subsequently, the physical, chemical and biological characterization of the wastewater taken in situ is performed in the laboratory of analysis. First results refer to the measurement of flow, indicating that there is an increased production of waste water on Sundays and Mondays, with a design flow of 15.44 L/s. It is indispensable data for the realization of the plant design. In this data major factor, the wrong connections and infiltration rate is included. The results of the physical, chemical and microbiological characterization performed in laboratory analyzes indicate that the parameters are off limits. It indicates the Unified Text of Secondary Environmental Legislation (TULAS), Annex 1 - Table 12 are: Demand Chemical Oxygen 250 mg/L, Biochemical Oxygen Demand in 5 days 382.33 mg/L, Suspended Solids 189 mg/L, Oils and Fats 22 mg/L, Surfactants 1,8 mg/L and fecal coliforms 2,2x105 CFU/100ml. As a conclusion, a treatment plant was designed with an efficiency of 87.99%; This percentage is based on the Biochemical Oxygen Demand in five days (DB5) soluble, and reveals if the values of the influent and effluent concentration thereof is correct. So it complies with the environmental regulations. We recommend this wastewater reuse after treatment and irrigation water, as the area is known for agricultural production.
