Method for the preparation of waste solutions containing organic substances and metals in the form of ions, generated during wet chemical cleaning of normal or nuclear technical equipment

摘要

A method is provided for conditioning a waste solution obtained during the wet-chemical cleaning of conventional or nuclear plants and containing organic substances and metals in ionic form. At least a portion of the organic substance is degraded by electrochemical treatment or UV radiation of the waste solution, at least one metal precipitates by the addition of phosphoric acid and a resultant phosphate precipitate is removed from the waste solution.
