Abstract: The present invention provides an ozonated water generator which can generate highly soluble and highly concentrated ozonated water in an efficient and simple manner. In an ozonated water generator comprising a supply tube for transmitting a treated liquid, a gas/liquid mixing device provided in the path of the supply tube, and an ozone supply structure for supplying ozone to the gas/liquid mixing device. The gas/liquid mixing device is provided with a magnet for creating magnetic force in the interior. Creating magnetic force in both the treated liquid and the ozone makes it possible to generate highly soluble and highly concentrated ozonated water in an efficient and simple manner.

Abstract: By effectively inhibiting ozone escape from ozonized water, a livestock sterilizing method which does not have the possibility of having an adverse effect on man and livestock is provided. Sterilizing of livestock is performed by including an ozonized water producing step of producing ozonized water with a particle size R of a contained ozone bubble satisfying 0<R<50 nm and an ozone concentration of 3 ppm to 20 ppm by a gas-liquid mixing method, and a step of sterilizing livestock by using the ozonized water produced in the ozonized water producing step. Since the particle size R is 0<R<50 nm, the ozone bubbles hardly receive buoyancy of the ozonized water. Therefore, the ozone bubbles do not rise to the water level, but stay in the ozonized water. As a result, ozone escape is effectively inhibited.

Abstract: To provide an ozonized water producing apparatus capable of efficiently and easily producing ozonized water with a high dissolution degree and a high concentration. In an ozonized water producing apparatus constituted by including a pipeline for passing water to be treated through, a gas-liquid mixing structure provided halfway in the pipeline, and an ozone supply structure for supplying ozone into the gas-liquid mixing structure, the gas-liquid mixing structure is provided with a magnet for exerting a magnetic force onto an inside. By causing the magnetic force to act on both the water to be treated and ozone, ozonized water with a high dissolution degree and a high concentration can be efficiently and easily produced.
