COMBINED CDI AND EDI SYSTEM FOR LIQUID RADIOACTIVE WASTE TREATMENT

摘要

The purpose of the present invention is to provide a combined capacitive deionization (CDI) capable of easily removing radiative nuclide inclined in liquid radioactive waste without replacing ion exchange resin, and an electric deionization (EDI) device for liquid radioactive waste treatment. For achieving the purpose, a combined CDI device and an EDI device for liquid radioactive waste treatment according to the present invention includes a reverse osmosis device part which removes a radiative material inclined in liquid radioactive waste by allowing the liquid radioactive waste transferred from the reverse osmosis device part to pass through a reverse osmosis membrane where; a CDI device part which adsorbs the radioactive material included in the liquid radioactive waste to the CDI device by allowing the liquid radioactive waste transferred from the reverse osmosis device part to pass through the CDI device; and an EDI device part which includes a three way value which completely removes ionic materials including radiative nuclide inclined in the liquid radioactive waste by allowing the liquid radioactive waste transferred from the CDI device part to pass through the EDI device, and discharges it.
