METHOD FOR TREATING WASTE WATER FROM THE DECONTAMINATION OF A METAL SURFACE, WASTE WATER TREATMENT APPARATUS AND USE OF SAID WASTE WATER TREATMENT APPARATUS

摘要

A method for treating waste water from the decontamination of the metal surface in a primary coolant circuit (12) of a nuclear reactor (14) comprises discharging a predetermined amount of an oxidation solution from the primary coolant circuit (12) into a reduction zone (16) connected to the primary coolant circuit (12) and reacting the oxidation solution with a reducing agent to form a reaction solution that is freed of oxidizing agent, and passing the reaction solution over an ion-exchange resin in order to form a desalinated solution, and returning the desalinated solution to the primary coolant and/or disposing of the desalinated solution. A waste-water treatment device (10) for carrying out the method is also provided.
