Document Type and Number:
WIPO Patent Application WO/2021/250745
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an ozone water production apparatus which makes it possible to reduce the ineffective consumption amount of ozone while reducing restrictions on the installation of the apparatus. An ozone water production apparatus (100) according to the present disclosure comprises: an oxygen gas supply unit (30) for supplying a first gas containing an oxygen gas; an another gas supply unit (31) for supplying a second gas containing at least one of a carbon dioxide gas, a nitrogen gas and a nitrogen oxide gas; an ozone gas production unit (32) for subjecting a gas comprising the first gas supplied by the oxygen gas supply unit (30) and the second gas supplied by the another gas supply unit (31) to an electrical discharge treatment to produce a third gas containing an ozone gas; and an ozone water production unit (34) for dissolving the third gas in dissolution water to produce ozone water.
