Abstract
Procedimiento de tratamiento de aguas que contienen sulfitos pro transformación de estos últimos en sulfatos mediante oxidación, caracterizados porque se realiza la oxidación de los sulfitos presentes en las aguas a tratar en una concentración previamente determinada, mediante introducción de oxígeno en el líquido bajo la forma de una fina dispersión, realizándose la reacción de oxidación a un pH ligeramente alcalino, a una temperatura comprendida ventajosamente entre 20ºC y 80ºC y en presencia de un catalizador constituido por hierro metálico que presenta una gran superficie para el contacto de la mezcla de líquido y de oxígeno, teniendo las aguas tratadas vertidas al alcantarillado un contenido máximo de sulfatos que es inferior a 970 ppm de sulfato de metal alcalino por litro de aguas residuales tratadas.
