Abstract

PROCESO Y EQUIPO DE DEPURACION ELECTROLITICA EN AGUAS RESIDUALES CONTAMINADAS UTILIZANDO CATODOS DE OXIGENO. EL PROCESO SE LLEVA A CABO EN UNA CELULA ELECTROLITICA CON UN ANODO Y DOS CATODOS ENTRE LOS QUE SE APLICA UNA CORRIENTE CONTINUA DE HASTA 100 V, DIFUNDIENDOSE EL OXIGENO A UNA PRESION ENTRE LA ATMOSFERICA Y 50 ATM Y CIRCULANDO LAS AGUAS EN REGIMEN TURBULENTO A 80 C COMO MAXIMO. LA FIGURA REPRESENTA DICHA CELULA ELECTROLITICA QUE, ADEMAS DEL ANODO Y LOS CATODOS, COMPRENDE LOS MARCOS (3) QUE CON LOS CATODOS DELIMITAN LOS COMPARTIMENTOS (4) POR LOS QUE CIRCULA EL O2 GASEOSO QUE ENTRA POR LAS ENTRADAS (7). A SU VEZ, LOS CATODOS CON EL ANODO DELIMITAN LOS COMPARTIMENTOS (5) POR LOS QUE CIRCULA EL AGUA RESIDUAL QUE ENTRA POR LAS ENTRADAS (7) Y SALE POR LAS SALIDAS (8). APLICACION DE INTERES MEDIOAMBIENTAL PARA LA DESTRUCCION ELECTROLITICA DE CONTAMINANTES ALTAMENTE TOXICOS CONTENIDOS EN LAS AGUAS RESIDUALES, EN LAS CORRESPONDIENTES ESTACIONES DEPURADORAS.
