METHOD FOR SUPPRESSING REDUCTION IN OZONE CONCENTRATION AND APPARATUS FOR GENERATING OZONE WATER AND SUPPRESSING REDUCTION IN CONCENTRATION

摘要

PROBLEM TO BE SOLVED: To provide a method for suppressing reduction in ozone concentration for suppressing reduction in ozone concentration of ozone water.;SOLUTION: A method for suppressing reduction in ozone concentration for suppressing reduction in ozone concentration of ozone water generated by mixing treated water and ozone gas includes: a step of preparing a cylindrical agitation blade 31 in which comb blades projecting in a tip direction are annularly arranged; a step of submerging the cylindrical agitation blade 31 in ozone water that is stored in a bottomed storage tank 9a once; and a step of rotating the cylindrical agitation blade 31 around a central axis in a state in which the tip direction faces the bottom.;EFFECT: Air bubbles of ozone gas in a lower layer confined in a layer (layer close to water surface) on the lower layer are crushed, sheared and agitated by rotation of the cylindrical agitation blade 31 to thereby efficiently refine the air bubbles, and the refined air bubbles of the ozone gas accumulate in the ozone water for a long period of time to thereby effectively suppress reduction in ozone concentration.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
