Diseño de una planta de tratamiento de aguas residuales para el cantón Santa Clara, provincia de Pastaza.

Abstract

This research was carried out to make a design a System of Wastewater Treatment in the canton Santa Clara, in province Pastaza, in order to design from plant sampled composite wastewater generated by the population in the discharge area sewer Autonomous Government Decentralized Municipal of Santa Clara, the same as they are evacuated directly from Rio Llandia, it was held without receive no treatment by altering the quality of the different materials collection was used in order to obtain the discharge rate at different time, flow rates obtained varied very little between the two values, therefore it took samples for 6 days, thus reaching a value of 24,14 L/s, and finding the largest amount days effluent discharge are Mondays. Subsequently, these samples were analyzed for physical, chemical and microbiological Laboratory Services ENVIROMENTAL at National University of Chimborazo. The characterization data showed us outside the rules indicated in the Unified Text (TULSMA), Annex 1, Table 12, the values obtained are: Biochemical Oxygen Demand in 5 days 120mg/L, oils and fats 10 mg/L, 2800 fecal coliform CFU/100ml and detergents 0, 21 mg/L. With this background pollution treatment plant was designed with an efficiency of 80,00% based on the Biochemical Oxygen Demand information that provided concentrations in the influent and effluent with influent characterization parameters comply with environmental regulations download to a sweet body, preventing serious acquire surrounding populations. It is recommended to calculate the flow days before starting the construction of the treatment plant so that there are considerable variations and wastewater are in the range considered.
