Document Type and Number:
WIPO Patent Application WO/2022/165932
Kind Code:
A1
Abstract:
Disclosed in the present invention is an electrocatalytic oxidation-electrodialysis coupling treatment system. By constructing a composite electrochemical coupling technology system in which multiple groups of electrocatalytic electrodes and electrodialysis membrane stacks are alternately combined, electrocatalytic oxidation is organically combined with the electrodialysis technology to form an integrated unit; raw wastewater simultaneously enters an electrode area and a membrane stack desalination chamber to generate an electrocatalytic oxidation and electroosmosis migration synchronous synergistic effect, freshwater is formed and discharged, and salt-containing clear water enters a membrane stack concentration chamber; under the action of electrodialysis, inorganic salt ions in the electrode area and the membrane stack desalination chamber enter the concentration chamber to form concentrated water, and after salt accumulation and circulation is performed on the concentrated water in the membrane stack concentration chamber, the concentrated water is subjected to devaporation and desalting treatment, and condensated water is used to be supplemented into the salt-containing clear water. According to the present invention, an electrocatalytic oxidation and electrodialysis mutual synergistic effect is formed, and the efficiency of degrading organic matters by means of electrocatalytic oxidation is enhanced; moreover, electrodialysis performance is improved by means of electrocatalytic oxidation, and high-concentration inorganic salts and hardly degradable organic matters in industrial wastewater are efficiently and synchronously removed.
