Abstract
En la presente investigación, se estudió la influencia de la densidad de corriente y la distancia entre electrodos, sobre el porcentaje de reducción de la DBO5 y la DQO del agua residual del camal del Distrito El Porvenir, mediante el método de electrocoagulación; para lo cual se construyó una celda electrolítica y se utilizó láminas de aluminio como electrodos en número de 3 ánodos y 2 cátodos, la cual se mantuvo constante, variando la diferencia de potencial, distancia entre electrodos de 1; 1,5 y 2 cm, densidad de corriente de 30, 50 y 100 A/m2 y tiempo de 40, 60 y 90 min. El pH antes de la electrocoagulación se mantuvo entre 3-4. Los mayores porcentajes de remoción de DBO5 y DQO alcanzados fueron de 96,92% y 97,36% respectivamente, a una densidad de corriente de 30 A/m2, distancia de electrodos, 1 cm, y tiempo de 90 minutos. Por consiguiente, se concluye que la electrocoagulación es una técnica eficiente para el tratamiento de agua residual de camal.
In the present investigation, the influence of the current density and the distance between electrodes was studied on the percentage reduction of the BOD5 and COD of the residual water from the El Porvenir District reservoir, using the electrocoagulation method; for which an electrolytic cell was built and aluminum sheets were used as electrodes in a number of 3 anodes and 2 cathodes, which remained constant, varying the potential difference, distance between electrodes of 1; 1.5 and 2 cm, current density of 30, 50 and 100 A/m2 and time of 40, 60 and 90 min. The pH before electrocoagulation was maintained between 3-4. The highest removal percentages of BOD5 and COD achieved were 96.92% and 97.36% respectively, at a current density of 30 A/m2, electrode distance, 1 cm, and time of 90 minutes. Consequently, it is concluded that electrocoagulation is an efficient technique for the treatment of bed wastewater.
