  • the improvement of the present invention based on the above technical solution is that the distance between the cathode electrode and the anode electrode is greater than or equal to the thickness of the water permeable membrane and is less than or equal to 20 mm.
  • ozone is produced in large quantities in the passage of oxygen through the discharge area in the form of bubbles.
  • the distance between the electrodes of yin and yang is increased, and the probability of oxygen evolution from the anode into the membrane in the plasma discharge state is reduced, and ozone is reduced in comparison.
  • the oxidative factors produced in water are more represented by hydroxyl-based transient oxidation factors.
  • the pitch is too large, the efficiency is lowered, and even the discharge process in the film cannot be performed.
