Diseño de una planta de tratamiento de agua residual para la Corporación de Productores y Comercializadores Orgánicos Bio Taita Chimborazo – COPROBICH.

Abstract

The purpose of this research work was to design a wastewater treatment plant for COPROBICH. since the residual water generated from the washing and centrifugation of the quinoa was discharged into the environment without some previous treatment. For this, a characterization of the residual water was carried out that allows determining the parameters that do not comply with the current regulations in said water, being the same: oils and fats (9 mg / L), real colour (3520 mg / L), solids sedimentable (13,500 mg / L), total suspended solids (1195 mg / L), total solids (4644 mg / L), total nitrogen (250 mg / L), COD (5000 mg / L), BODs (2990 mg / L). active strains (17,5 mg / L) and faecal coliforms (240). A biological treatment is carried out, which is ratified by a biodegradability index of 0.6 found in the wastewater sample, which means that it is very biodegradable. A primary settler was designed, which served to lower the organic load of the water, since it removes the suspended solids that subsequently settle by gravity in it, then the wastewater enters an aeration process in a biological reactor in which the greatest amount of contaminant load was eliminated, followed by a secondary settler in which the organic mass floccules previously formed by the microorganisms present in the biological reactor will precipitate and finally a filter which finishes lowering the excess contaminant load and achieves have a treated wastewater that complies with environmental legislation, all this thanks to the fact that the technical proposal of the wastewater treatment plant achieves a percentage of removal of pollutant parameters of 97.4% making it clear that the processes sized for said plant they are efficient, this water can be quietly recirculated in the same process or reused to any relevant purpose.
