Abstract

Mejoras en el objeto de la patente principal nº 9400299 por proceso y equipo de depuración electrolítica de aguas contaminadas utilizando cátodos de oxígeno. Las mejoras en el procedimiento se caracterizan por el hecho de que el o los ánodos utilizados en la patente principal son inertes, y por el hecho de que comprenden al menos un ánodo adicional de distinto material, permitiendo la oxidación que tiene lugar en el mismo regular dicha depuración electrolítica. El ánodo adicional es de hierro o acero y el pH del agua residual se regula utilizando medios de control que permiten aumentar o disminuir la concentración de iones Fe sup,2+ . Las mejoras en el equipo se caracterizan por el hecho de que comprenden por lo menos un ánodo inerte (1), por lo menos un cátodo de difusión de oxígeno (2), delimitándose entre al menos un cátodo y al menos un ánodo un compartimento (5) por el que circula el agua residual, y por el hecho de que además comprende al menos un ánodo adicional (9) de distinto material situado en el compartimento (5).
