(CN212864231-U) NOVELTY - a filter element; A separating device and a water treatment device; the filter core comprises at least one pair of electrode groups and a film structure formed by winding more than one bipolar film; the electrode group at least comprises a porous electrode; each bipolar film is composed of a cation exchange membrane and an anion exchange membrane jointed together; there is no flow passage between the cation exchange membrane and anion exchange membrane forming the same bipolar membrane. . using porous electrode and bipolar membrane and bipolar membrane wound into a rolling structure; it can avoid the problem that the polar room water hydrolysis generates gas and fouling 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 view of a roll-type bipolar membrane filter element. Roll-type bipolar membrane filter element (10) Porous electrode (100,200) Bipolar membrane (300)
