Propuesta de tratamiento de aguas residuales descargadas en la quebrada Huizhil de la ciudad de Cuenca

Abstract

The lack of a wastewater treatment system in the Huizhil ravine of Baños of Cuenca has generated pollution problems in the water and backs of the stream. This work aims to propose an adequate treatment method that reduces water pollution and provides a better living standard for the population. A survey to collect information of the Huizhil area was carried out determining design parameters such as population, flow, and water quality through statistical analysis, laboratory test, and field tests, a bibliographic review was applied to evaluate the biodigester and wetland treatment systems, proposing a technical proposal on these methods, hoping that their use will generate a reduction of impacts. The parameters established for the design of wastewater treatment systems are capable of providing a good service to the population, providing reliability and economy for a long time. As a result, a Rotoplas self-cleaning biodigester with a capacity of 3000 liters, and a horizontal subsurface flow wetland with a required area of 175 m^2 were proposed. The same ones that, by working together, guarantee that the wastewater from the Huizhil stream will reduce its degree of contamination, providing adequate social well-being for the residents of the area, and a low budget for construction and maintenance.
