Ozone has been widely used in many fields due to its strong oxidation ability. Under the conditions of the experiments, the results are as follows: With an increasing applied voltage, both ozone concentration and ozone generation rate increase, while ozone generation efficiency increases at first, reaching peak value, then decreases slowly; With an increasing gas flow rate, ozone concentration decreases, while both ozone generation rate and ozone generation efficiency increase at first, reaching peak value, then decrease; When power supply frequency is changed in the range from 5.0kHz to 9.9kHz, no apparent laws of ozone concentration, generation rate and generation efficiency are found; When gap spacing is changed in the range from 0.3mm to 0.5mm and dielectric thickness is unchanged, shorter gap doesn’t show better effect.
