Referring to fig. 4 and 5, a schematic winding diagram of a positive electrode membrane 3, a first current guiding net 4, a positive ion membrane 5, a second current guiding net 6, a negative ion membrane 7, a third current guiding net 8, a negative electrode membrane 9 and an insulating membrane 10 in the present invention is given, wherein the positive electrode membrane 3, the first current guiding net 4, the positive ion membrane 5, the second current guiding net 6, the negative ion membrane 7 and the third current guiding net 8 form a group, are stacked in sequence from inside to outside, and are wound on a central rod 1 after being stacked; the negative electrode film 9 and the insulating film 10 are sequentially stacked and wound on the central rod 1, the negative electrode film 9 is arranged inside, the insulating film 10 is arranged outside, and the starting points of the two groups of windings are symmetrically distributed along the central rod.

Raw water enters the positive and negative electrode membranes and the space formed by selectively permeating the negative and positive ion membranes from the liquid inlet at the upper end and flows out from the lower end. When raw water flows between the positive electrode membrane, the negative electrode membrane and the positive ion membrane, under the action of an electric field, negatively charged chloride ions in the water migrate to the positive electrode membrane, and negatively charged ammonium adipate ions migrate to the negatively charged negative electrode membrane, are adsorbed by the electrode membranes and are stored in the double electrode layers. Along with the increase of the adsorbed ions, the ions are enriched and concentrated on the surface of the electrode membrane, so that the separation of ammonium adipate and chloride ions is realized, and a recycled ammonium adipate product is obtained. In the process of electric adsorption, the storage/release of electric quantity is realized by the absorption/desorption of ions instead of chemical reaction, so that the quick charge and discharge can be realized, and the electrode structure can not be changed because the absorption/desorption of ions is only generated during the charge and discharge, so the charge and discharge times are not limited in principle. When raw water containing a certain amount of salts passes through an electro-adsorption module composed of a high-functional electrode material, ions are stored in an electric double layer on the surface of an electrode under the action of a direct current electric field until the electrode is saturated. At this time, the DC power supply is removed, the positive and negative electrodes are short-circuited, and ions stored in the electric double layer are returned to the channel again due to the disappearance of the DC electric field, and the electrodes are regenerated as a result of the discharge of the water flow.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
