Detailed Description
The utility model arranges a cathode tube 1 and an anode tube 2 with identical structures in sewage in a sewage tank 12 with higher saline-alkali acid content. The structure of the cathode tube 1 and the anode tube 2 is substantially identical, and only one serves as a cathode and the other serves as an anode, and the ion exchange membrane 8, specifically, a cation exchange membrane or an anion exchange membrane is determined according to the cathode and the anode.
Cathode tube 1 or anode tube 2: since the cathode tube 1 and the anode tube 2 have the same structure, the detailed structure thereof will be described only with one electrode tube. The upper and lower parts of the area (cylindrical area 10) surrounded by the ion exchange membrane 8 are respectively and hermetically installed through an upper sealing component 6 and a lower sealing component 9, the cylindrical ion exchange membrane 8 of the cathode tube 1 adopts a cation exchange membrane, and the cylindrical ion exchange membrane 8 of the anode tube 2 adopts an anion exchange membrane; the cathode tube 1 and the anode tube 2 are directly placed in the sewage tank 12 with higher saline-alkali acid content, and are directly subjected to diaphragm electrowinning with anions and cations such as the saline-alkali acid in the sewage tank 12 with higher saline-alkali acid content through the cation exchange membrane and the anion exchange membrane, so that the anions and cations enter the purified water in the cylindrical region 10.
