RECOVERY OF BORON AND REMOVAL OF METAL IONS FROM PRIMARY COOLING WATER OF NUCLEAR POWER PLANT BY USING ELECTRODEIONIZATION(EDI) PROCESS |
摘要 |
PURPOSE: A recovery of boron and removal of metal ions from primary cooling water of nuclear power plant by using electrodeionization(EDI) process is provided, which can reduce treatment cost of waste drastically by changing packing method of ion exchange resin from the existing electrical deionization equipment, and can protect workers from dangers of exposure to radioactivity. CONSTITUTION: The system comprises a pretreatment device(100) and three electrical deionizing stacks(210) set serially. The electrical deionizing stacks(210) are composed of a cation exchange membrane and an anion exchange membrane, at the both sides of which concentration chambers are equipped and between the exchange chambers a desalting chamber is provided. In the desalting chambers, a cation exchange matter, an anion exchange matter and mixed ion exchange matter of cation and anion are filled serially from the water inlet.
