Evaluación del funcionamiento de la planta de Tratamiento de aguas residuales del sector valle Mulinliví de la parroquia la victoria, perteneciente al Cantón Pujilí, provincia de Cotopaxi

Abstract

The present experimental work is focused on the evaluation of the correct operation of the Wastewater Treatment Plant (WWTP), located in the parish of La Victoria; for which the national and international regulations in force were used, since the treated water flows into a dry creek located in an area that is undergoing population and commercial growth. First, a general information survey was carried out: location, on-site visits, etc. In addition to the aforementioned, flow measurements were taken in the influent and effluent for 30 consecutive days, using the concepts and techniques recommended by Metcalf & Eddy. It was also necessary to collect composite samples in the inflow and outflow using the standards and techniques established in the Standard Methods for the Analysis of Drinking and Waste Water (SMWW); to transport the samples to a laboratory using the NTE INEN 2 169:1998 standard. With the results obtained in the laboratory, which gives us to know the physical, chemical and biological properties of the water under study, we proceeded to compare with the limits allowed by the TULSMA to discharge treated water into a body of fresh water, complemented with a technical analysis of the dimensions of the existing treatment units, with the minimum design parameters recommended by CONAGUA and PAHO, viable alternatives are proposed, which generate a solution to the treatment system, such as implementing: A split tank with bypass, a FAFA and a sludge drying bed.
