Electro-deionization (EDl system) is a scientific water treatment technology, in which dielectric ions in water passing through the partition move directionally under the action of DC electric field, and water quality is purified by selective permeation of ions by exchange membrane. Between a pair of electrodes of electrodialyzer, a plurality of groups of negative membranes, positive membranes and separators (A and B) are aIternately arranged to form a concentrated chamber and a weak chamber (i.e., cations can pass through the positive membrane and anions can pass through the negative membrane). Cations in the light chamber water migrate to the negative electrode and pass through the positive membrane, and are intercepted by the negative membrane in the concentrated chamber; Anions in the water migrate to the cathode direction and are intercepted by the anode membrane in the concentrated chamber, so that the number of ions in the water passing through the light chamber gradually decreases and becomes fresh water, while the concentration of dielectricions in the concentrated chamber continuously rises due to the continuous influx of anions and cations in the concentrated chamber, and becomes concentrated water, thus achieving the purpose of desalination, purification, concentration or refining.
