Diseño de una planta de tratamiento de aguas residuales para los barrios: Central, El Progreso, Buganvillas, Los Guayabales, de la parroquia de Mindo del cantón San Miguel de los Bancos en la provincia de Pichincha

Abstract

This work includes the design of a wastewater treatment plant for the population of Mindo, located in the San Miguel de Los Bancos canton, belonging to the province of Pichincha. The first chapter contains the relevant general information and the current problems that the Canchupi River presents due to the direct outlet of the sewage from the Central, Progreso, Buganvillas, and Guayabales neighborhoods belonging to the Mindo Parish head, in addition, we find the delimitation and project goals. In the second chapter, a description of the generalities of wastewater, its physical, chemical, and biological is made, this is attributed to define the methodology and the wastewater treatment system to be used, it was concluded that the most viable and economical was a system of certainty gaps which is defined in this chapter. The legal regulations for the parameters that were used and general information about the place and zoning where the present work will be carried out were also applied. Subsequently, in chapters III, IV, and V, the materials and methods used are found, such as the determination of the number of samples for the collection of wastewater based on the INEN 2226 Standard (2013) to evaluate the physical, chemical, and biological residues from the water, the biodegradability index is prolonged using the BOD5/COD ratio, thereby prolonging the conventional secondary treatment method with biological systems as a viable approach, since the water has moderately degradable organic matter. Utilizing the aforementioned methods, the dimensioning of the treatment plant began, which consists mainly of an inlet channel, an anaerobic lagoon, and a facultative one, before this, and with the calculations carried out, the plant is regenerated and is presented in a plan. in AutoCAD. The sections to studies economic, technical, and social.
