Abstract: The present invention provides a low-cost ozone production method and apparatus for carrying out ozone/oxygen separation using an ozone adsorbent, that re-uses the recovered oxygen as a feed for ozone production, and that desorbs and recovers the adsorbed ozone using dry air. In the method and apparatus, a gas containing an ozone and oxygen two-component gas supplied from an ozone generator is pressurized, introduced into an ozone adsorbent-packed adsorption column, and brought into contact with the adsorbent to adsorb the ozone to the adsorbent. Using dry air as a counterflow purge gas for the adsorbed ozone, the ozone is desorbed from the ozone adsorbent-packed adsorption column loaded with adsorbed ozone by depressurizing the adsorption column or air is introduced as a purge gas from the rear of the column into the adsorbent bed, whereby an ozone and air two-component gas is recovered.
