Abstract
Process for purifying water polluted by sulphides and/or various organic substances particularly those originating from tanning works, comprising a stage of salt formation to render the water electrolytically conducting, a stage of electrocatalytic oxidation and a stage of separation by settling and/or filtering out solids (protein materials) and if appropriate a stage of recovering the salt by electrodialysis and subsequent recycling; corresponding equipment comprising an oxidation cell equipped with an anode capable of ensuring a high oxygen discharge overvoltage and a cathode capable of ensuring a low hydrogen discharge overvoltage. <IMAGE>
