Active oxygen treatment device, treatment method using active oxygen, and ozone ufb-containing liquid producing device

A treatment method with active oxygen, comprising:

• (1) producing an ozone UFB-containing liquid in which ultrafine bubbles comprising ozone are comprised in a liquid;
• (2) storing the produced ozone UFB-containing liquid in a first reservoir section;
• (3) applying energy necessary to decompose at least a part of the ozone comprised in the ultrafine bubbles into active oxygen to the ozone UFB-containing liquid in a stored state in the first reservoir section, decomposing at least part of the ozone into the active oxygen, and preparing an active oxygen UFB-containing liquid in which the ultrafine bubbles comprising the active oxygen are comprised in a liquid;
• and
• (4) supplying the active oxygen UFB-containing liquid stored in the first reservoir section to a substance to be treated, wherein
• the stored state refers to a state without the ozone UFB-containing liquid flowing into the first reservoir section and the ozone UFB-containing liquid flowing out of the first reservoir section, and
• the energy application is irradiation with ultraviolet rays.

An ozone UFB-containing liquid producing device that generates an ozone UFB-containing liquid in which ultrafine bubbles comprising ozone are comprised in a liquid, the ozone UFB-containing liquid generating device comprising:

• a liquid reservoir section that stores a liquid,
• wherein the liquid reservoir section comprises
• a UFB generating device that produces a UFB-containing liquid in which the ultrafine bubbles are comprised in the liquid stored in the liquid reservoir section, and
• a plasma actuator,
• the plasma actuator is provided with a first electrode and a second electrode with a dielectric body sandwiched therebetween and generates an induced flow comprising the ozone by applying a voltage between the first electrode and the second electrode, and
• the plasma actuator is disposed such that the induced flow flows inside the liquid reservoir section.
