Abstract
An intermittent ozone feeding apparatus including an ozonier for producing ozonized oxygen, an adsorption-desorption tower for adsorbing ozone from the ozonized oxygen and desorbing the ozone with oxygen produced from adsorbing ozone in said adsorption-desorption tower being recycled to the ozonizer, adsorption-desorption tower being cooled during an ozone adsorption period and being heated at a temperature higher than that in the adsorption period during the ozone desorption period while the adsorption-desorption tower is subject to suction under a reduced pressure so as to desorb ozone wherein the sucking operation is maintained until the pressure on the suction side of the tower side is lower than that within the adsorption-desorption tower after the desorption period has been completed.
