3 Terms and definitions

The following terms and definitions apply to this standard. 3.1 Continuous deionization continouusdeionizatin, CDI (abbreviation) Taking the potential difference as the driving force, using the anion and cation exchange membrane to selectively permeate the anion and cation in the aqueous solution, and the ion of the ion exchanger Exchange and transfer, as well as the regeneration of ion exchangers by the H+ and OH- generated by hydrolysis under the conditions of concentration polarization, make the aqueous solution The separation process in which the ions in the membrane are continuously transferred from one side of the membrane to the other side. 3.2 The anion and cation exchange membranes, the partitions and electrodes of the fresh and concentrated water chambers are arranged according to certain rules to form a fresh water chamber, a concentrated water chamber and an electrode chamber. The water chamber is filled with ion exchanger, or both the light and concentrated water chambers are filled with ion exchanger, and the electrodeionization is clamped by clamping parts in the form of a plate and frame unit. 3.3 The anion and cation exchange membranes and the partitions and electrodes of the fresh and concentrated water chambers are arranged according to certain rules to form a fresh water chamber, a concentrated water chamber and an electrode chamber. The water chamber is filled with ion exchangers, or both the light and concentrated water chambers are filled with ion exchangers, and they are filled into cylindrical airtight containers in the form of cylinders. The electrodeionization unit. HY/T 120-2008
