NOVELTY - Purifying iodine-containing salt waste water comprises using flow electrode capacitance deionization device for adsorption treatment of iodine containing salt waste water, where the flow electrode capacitance de-ionizing device comprises anode flow electrode chamber, water inlet chamber and cathode flow electrode chamber. The cathode flow electrode chamber contains cathode flow electrode liquid. The cathode flow electrode liquid comprises electrolyte, conductive agent, redox active material and solvent. USE - The method is useful for purifying iodine-containing salt waste water. ADVANTAGE - The method: has simple operation, low processing cost, low processing energy consumption, wide application range, high desalting efficiency, excellent desalting effect, stable operation, continuous desalting, and no secondary pollution; does not increase energy consumption, and causes secondary pollution; and realizes better purification effect of iodine-containing salt waste water.
