When in operation, the DC power supply 8 is connected, and the working voltage of the device is controlled between 0 and 10V according to different water quality conditions. Under the action of the external electric field, a part of charged ions in water are adsorbed in the gaps of the particle electrode 4, and the other part of charged ions migrate to the electrode surface opposite to the charge of the charged ions and are stored in an electric double layer formed on the electrode surface, so that charged particles, dissolved salts and the like in the water between the electrode plates are obviously reduced due to adsorption in the electrode gaps and enrichment of the electrode surface, and the water purification and desalination effects are achieved.
As the reaction proceeds, the ions adsorbed on the electrode reach saturation, the adsorption capacity is reduced, and the effluent quality does not reach the standard and needs to be regenerated. At the time of regeneration, the direct current power supply 8 is turned off, a reverse voltage is applied, and water is simultaneously introduced to perform washing, at which time charged ions are released into the washing water to form concentrated water.
