Problems solved by technology

[0002] Electrodialysis refers to the purification technology realized by using the selective permeability of the ion exchange membrane under the drive of an external DC electric field. Anions and cations move to the anode and cathode respectively. If the charges are opposite, the ions can pass through; if their charges are the same, the ions will be repelled, and the fresh water and concentrated water will be discharged from the two outlets after the purification is completed; after the electrodialysis device works for a long time, there will be too much adsorption on the ion exchang...

Abstract

The invention discloses a water purification method and system with a pure-mineral double-drinking mode. Water in a water tank is conveyed to an electrodialysis module through a water pump; the electrodialysis module is normally started, the first water purification valve and the first wastewater valve are opened, the second water purification valve and the second wastewater valve are closed, purified water purified by the electrodialysis module reaches the water purification main path through the first water purification branch, and wastewater generated by the electrodialysis module is conveyed back to the water tank through the first wastewater branch and enters the electrodialysis module again for purification. Opening and closing of the pipeline can be flexibly adjusted to cooperate with electrode polarity conversion of the electrodialysis device, the purification efficiency is good, purified water can be subjected to multiple treatments, and multiple purposes of water purification are achieved.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a water purification method and system with pure ore double drinking modes. Background technique [0002] Electrodialysis refers to the purification technology realized by using the selective permeability of the ion exchange membrane under the drive of an external DC electric field. Anions and cations move to the anode and cathode respectively. If the charges are opposite, the ions can pass through; if their charges are the same, the ions will be repelled, and the fresh water and concentrated water will be discharged from the two outlets after the purification is completed; after the electrodialysis device works for a long time, there will be too much adsorption on the ion exchange membrane Impurity ions will gradually affect the follow-up purification efficiency. This problem can be solved by exchanging the polarities of the two electrodes. However, the existing elect...
