Evaluación del estado del agua residual doméstica, mediante el monitoreo y análisis de parámetros fisicoquímicos y microbiológicos como insumo para el diseño conceptual del sistema de tratamiento de agua residual en la vereda balcones de Restrepo Meta.

Abstract

The present study evaluates the degree of contamination present in the wastewater of a point discharge located in the southwestern zone of the municipality of Restrepo Meta, which collects all the wastewater from the middle of the urban municipality. To fulfill this purpose, a characterization of the residual water was initially carried out by reviewing primary information and monitoring in situ parameters such as: pH, dissolved oxygen, conductivity, flow and temperature. The ex situ parameters analyzed in the laboratory were: BOD, COD, oils and fats, nitrates, ammonia nitrogen, total phosphorus, fecal and total coliforms as well as total suspended solids. For the monitoring of both in situ and ex situ parameters, the climatic temporality of periods of rain and drought was taken into account, as well as the development of the activities of the population (Business days and not Business days) that corresponded to monitoring four (4) Possible scenarios of wastewater generation, which in turn were validated in triplicate, to finally carry out 12 composite samples of 24 hours in the months of January and May respectively. The characterization of the wastewater showed an inversely proportional behavior of the parameters in relation to the flows, the parameters presented data of greater magnitude in the dry period, with a 45% reduction in the parameters of BOD, COD, total suspended solids and the conductivity in the period of rain. After obtaining the proposed characterization, the information was processed and analyzed statistically, obtaining an evaluation of the contaminant load of the shedding to later define the basic aspects of design, population projection and level of complexity of the system, finally allowed to propose a water treatment system residuals for the southwestern area of the municipality of Restrepo Meta.
