Modelamiento de la autodepuración de la acequia Pumamaqui, Comunidad de Pesillo, cantón Cayambe.

Abstract

The present investigation is mainly based on modeling the self-purification capacity of the Pumamaqui ditch that is located in the community of Pesillo, Olmedo parish, Cayambe canton, Pichincha province, which has an extension of 12 kilometers by sampling and determining parameters of water quality During the recognition of the place and at the end of it, relevant points were determined which began in the capture of the La Chimba River to the limit with the province of Imbabura. Sampling was carried out five times during the month of November 2019, after taking it, parameters were analyzed that determine water quality such as Chemical Oxygen Demand (COD), Biochemical Oxygen Demand at 5 days (BOD5), Solids Suspended, Nitrates and Phosphates. At the end of the analysis and with the results obtained in the laboratory of the Salesian Polytechnic University - Quito Headquarters - South Campus, the values obtained will be modeled, giving us as a result that the Pumamaqui ditch if self-purification of COD parameters is achieved with 68.19 % and 76.84 %, BOD5 65.42 % and 92.88 %, Suspended Solids 68.43 % and 85.32 %, Nitrates 68.38 % and 93.85 %, and Phosphates 66.38 % and 85.32 %, based on the first order law and Qual2K software, respectively.
