Diseño e implementación de la planta de Tratamiento de Aguas Residuales de Tenería Núñez

Abstract

The wastewater treatment system was designed to minimize and eliminate pollutants present in the discharges of the leather process at Tenería Núñez. The system is designed to eliminate suspended solid organic substances and organic substances and for this, preliminary treatment processes, physical and chemical processes will be applied, which obtain wastewater suitable for discharge, complying with current regulations. The main processes for use are macro grinding of suspended tissues, effluent homogenization, neutralization, coagulation, flocculation, precipitation, sedimentation, sludge removal, filtration, controlled aeration / oxygenation, and sludge drying for removal. The treated water quality study used statistical tools that facilitate interpretation and decision making. The water quality indices (ICA) have been promoted in order to contribute to the communication of reports on the condition of the water to society, where the results of evaluations of the physical and chemical characteristics of the water corresponding to periods between 2019 and 2020 , whose objective is to compare the conditions of the water of Tenería Núñez before and after the actions taken for its restoration; For this, 17 physical and chemical parameters of the water were analyzed using standardized techniques that include an ISCA. The results reveal that the wet process of Tenería Núñez presents a high degree of contamination, with contributions of organic matter and sediments; Temporal variations in water quality were found that show the effects of the different periods in which the analyzes were carried out.
