Abstract

The invention relates to a method and to a device for scrubbing liquid effluents laden with dissolved or undissolved organic and/or inorganic substances and continuously fed at a flow rate Df. After a preliminary effluent-floating operation if required, the method comprises carrying out at least one treatment cycle, the treatment cycle including a first step in which the effluents are subjected to an electrolytic treatment by circulation in a first compartment while generating a very strong turbulence, followed by a second step in which the undissolved elements contained in the effluents are agglomerated by coagulation/flocculation before circulating the effluents in a second free surface compartment, with the scraping of the sludge carried out at the upper portion, while bubbling and maintaining a reduced turbulence in said second compartment.
