Abstract: A hydrogen peroxide water manufacturing device includes an ejector unit including an introduction-side diameter-increasing portion to which water to be treated is introduced, a nozzle portion connected to the introduction-side diameter-increasing portion and having an introduction opening to which a source gas containing oxygen gas is introduced from outside, on a side wall, and a discharge-side diameter-increasing portion that is connected to the nozzle portion and from which the water to be treated mixed with the source gas is discharged, and an electrolysis unit disposed downstream of the ejector unit and including electrolytic electrodes to electrolyze the discharged water to be treated mixed with the source gas and generate hydrogen peroxide by using the source gas as a source.

Abstract: A water treatment system includes: a water treatment device; a feed-water pump that feeds water to be treated to the water treatment device; an ozone generator that generates ozone-containing gas containing ozone gas and oxygen gas; and a direct-current power supply that supplies direct-current power. The water treatment device includes: an ejector including an inlet-side wider-diameter part into which the water is introduced, a nozzle in communication with the inlet-side wider-diameter part and including a sidewall including an inlet opening into which the ozone-containing gas is introduced, and an outlet-side wider-diameter part in communication with the nozzle, from which the water mixed with the ozone-containing gas is ejected; and an electrolyzer located downstream of the ejector and including an electrolysis-purpose electrode supplied with the direct-current power to electrolyze the ejected water mixed with the ozone-containing gas.
