The invention discloses an electric deionization water purifying device and a method without scaling and recovering anion and cation. The electrodeionization device consists of five compartments, compartments of the order were built in the anode chamber, the anode cathode chamber filled with cation exchange resin, the first light room, room, filled with strong anion exchange resin second light chamber and built-in cathode, both sides of the first light chamber with two cation exchange membrane were separated from the the anode chamber and the concentrated chamber, separated by second light room on both sides with two anion exchange membrane with concentrated chamber and a cathode chamber. The anode water, the cathode water and the concentrated water are respectively recycled and periodically renewed, and the raw water flows through the first light chamber and the second light chamber to produce pure water. The construction of a membrane stack makes the concentrated chamber always maintain the acidic environment, inhibit the fouling of anion membrane surface; polar water from the water diversion, the scaling of the cathode surface is avoided; the raw water in the anion and cation enrichment in concentrated water, using Recyclable.
