Abstract

Método de purificar biológicamente agua residual, rica en hidratos de carbono o proteínas, mediante tratamiento anaerobio y aerobio combinado, caracterizado porque el agua residual se trata en una etapa anaerobia bajo condiciones adecuadas para la fermentación metánica con la subsiguiente reducción de contaminantes, preferentemente en una concentración muy elevada de lodo, en que se deriva el gas metano originado, se somete el agua con contenido de lodo que se ha formado a una separación del lodo, con lo que se origina un primer concentrado de lodo, con lo que se origina un primer concentrado de lodo, el cual se recircula por lo menos parcialmente a la etapa anaerobia, porque la fase líquida separada se trata en una etapa aerobia con alimentación de gases que contienen oxígeno y se somete a continuación a una separación del lodo para formar un segunda concentrado de lodo, del cual se recircula una parte a la etapa aerobia, mientras que otra parte es recirculada a la etapa anaerobia, y porque, en consonancia con la formación de lodo excedente, se deriva para su eliminación el lodo excedente del primer concentrado de lodo.
