STERILE WATER GENERATION DEVICE AND STERILIZING CLEANING METHOD

摘要

Problem] To provide a sterile water generation device and sterilizing cleaning method with which the sterilizing power and cleaning effects of acidic electrolyzed water can be increased. [Solution] An electrolysis device (11) electrolyzes an electrolyte water solution that includes a chloride and has been previously adjusted to a pH of 3 to 5 by a pH adjuster and generates acidic electrolyzed water. An acidic water vessel (13) is connected to the electrolysis device (11) and collects the acidic electrolyzed water generated by the electrolysis device (11). A chlorine gas circulating means (14) recovers chlorine gas generated from the acidic electrolyzed water in the acidic water vessel (13) and supplies the recovered chlorine gas by bubbling to the acidic electrolyzed water in the acidic water vessel (13). A transition metal supplying means (16) is provided to the interior of the acidic water vessel (13) so as to be able to supply a solution that comprises a transition metal.
