When the electrolytic solution 8 is introduced into the tank 4 and a direct current is applied, the anions 9 contained in the electrolytic solution 8 move toward the anode 5 and the cations 10 move toward the cathode 6. Then, these ions are separated by the separator 7 between both electrodes.
The alkaline water 11 is taken out from the cathode 6 side and the acidic water 12 is taken out from the anode 5 side.

The high-concentration organic wastewater to be treated in the present invention contains Cl − discharged from the human body.
It contains about 0 mg of Cl − . For this reason, when this treated water is electrolyzed, it is mixed with alkaline water of pH 11 or above.
Acidic water of 3 or less can be obtained.
