Description
Technical Field
The utility model relates to a water treatment field especially relates to a membrane structure is piled to EDI convenient to installation.
Background
Electrodeionization (EDI) is a novel water treatment method which fills mixed bed resin between ion exchange membranes and realizes continuous desalting under the action of a direct current electric field.
It is believed that the principles of EDI can be divided laterally into ion exchange, selective migration of ions in a direct current electric field, and electrical regeneration of the resin. In high-purity water, the conductivity of the ion exchange resin is 2 to 3 orders of magnitude higher than that of water in contact with the ion exchange resin, so that almost all ion migration from the solution to the lipid surface is completed through the resin. Ions in water are firstly adsorbed on the resin particles due to the exchange effect, and then migrate to the surface of the membrane through an ion propagation channel formed by the resin particles under the action of an electric field and enter the concentrated water chamber through the ion selective membrane. Meanwhile, at the interface where the resin, membrane and water are in contact, polarization in interfacial diffusion causes water to dissociate into hydrogen ions and hydroxide ions. Besides part of them participate in load current, most of them play the role of regenerating resin, so that the 3 processes of ion exchange, ion migration and electric regeneration are accompanied and mutually promoted, and the goal of continuous deionization is reached.
