Estudio y diseño del sistema de tratamiento de las aguas residuales provenientes del sector Nor-Este de la Universidad Técnica Particular de Loja.

Abstract

The present study contains: information about the area and identification of existing sewerage networks, the selection of gauging points, recollection and further testing of samples in regards to wastewater, the design of the units conforming the treatment system sewage and economic analysis of the cost of physical infrastructure, operation and maintenance. Previous to the design we evaluated at a laboratory scale -Flocculation physicochemical processes such as coagulation-Flocculation and advanced oxidation processes in Fenton and photo Fenton types.In the coagulation process- we worked on flocculation pH 11.29, this sample provided excellent results aluminum polychloride at an optimal dose of 300ppm with a total COD removal of 51.14%. In the Fenton process we experimented at a pH of 9.55 which was at the amount the sample had been, changing three different concentrations of ferrous sulfate as a catalyst and hydrogen peroxide as oxidizing agent obtaining a biodegradable material removal, measurements such as DQO of 97.33% to a concentration of 150ppm of FeSO4 y 300ppm of H2O2.
