(CN212864232-U) NOVELTY - A separation device and water treatment device thereof, bipolar membrane electrodeionization device comprises at least one pair of characteristic electrode group and more than one bipolar membrane located between two electrodes of the characteristic electrode group, the electrode group at least comprises a porous electrode; Each bi-polar membrane is composed of a cation exchange membrane and an anion exchange membrane which are jointed together. The bipolar membrane electrodeionization device uses the structure of porous electrode and bipolar membrane, which can avoid the problem of gas and fouling caused by polar room water hydrolysis in the existing technology; and it can improve the desalting rate; it has high water producing rate and less water resource waste. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the desalination state of a bipolar membrane electrodeionization device for water treatment device (Drawing includes non-English language text).
