Diseño de un sistema de tratamiento de aguas residuales para el camal municipal de la ciudad de Macas cantón Morona provincia de Morona Santiago.

Abstract

A treatment system for wastewater discharges generated in the process of slaughtering the Municipal slaughterhouse in Macas, Morona Santiago Province was designed; type composite samples, including small simple samples collected from 19:00 to 00:00 hours was taken; the initial characterization of the samples, identifies the parameters that are outside the permissible limit in the Standard of Environmental Quality Effluent Discharge: Water Resource, Book VI, Annex 1, Table 10 TULSMA, these being: Chemical oxygen demand (COD), biochemical oxygen demand (BOD), oil and fats, phosphates, total nitrogen, iron, suspended solids, settleable solids, total solids and fecal coliforms. It proceeded to take two points flow based flow measurement structures according to point 1 spill area knockback, bleeding, cut legs, skinning and party channels. To perform treatability tests took into account the level of biodegradability which was 1.68, indicating that the effluent has very biodegradable organic contaminants nature that can be treated in a biological system. equipment for the respective treatment system according to the results of biological degradation are dimensioned effluent having: a system bars before unloading at point 1, channel, porous mesh grease trap moisture using artificial lechuguines (Eichhornia crassipes) and activated carbon filter. Validation sample with the characterization of wastewater obtained after treatability testing and removal percentages of the parameters are: 99.5 % COD, BOD 98.7 %, oils and fats 67.9 %, phosphate 99, 5 % Total nitrogen 95.8 %, 99.2 % suspended solids, settleable solids 100 %, 99.6 % total solids and 99,99 % fecal coliforms. With the proposal, the Municipal Slaughterhouse in Macas complies with the requirements established in environmental legislation. It is recommended that the company implements the study to minimize the environmental impact in Jurambaino river and its surroundings.
