Patent ID: 7964104

Claim:
A production method for active antiseptic water or an active antiseptic water-based fluid that contains 0.08 to 0.5 mg/L of nitrite ions and/or sulfite ions, and that contains substantially no chlorine, the method comprising: using a treatment apparatus having: a treatment tank, a vibrating stirrer disposed inside the treatment tank and comprising an insulated vibrating stirrer having a vibration generator, a vibration rod connected to the vibration generator or a linkage section between the vibration generator and the vibration rod, at least one vibration vane for vibration and at least one auxiliary vane fixed to the vibration rod, wherein the auxiliary vane is substantially devoid of vibration ability, a vibration vane-fixing member, and an insulation member for electrically separating the vibration rod or a vibration transmission member in a non-immersed position in a treatment bath, near the vibration generator and away from the vibration vane and auxiliary vane, a photocatalyst layer or a layer having a photocatalyst and a bactericidal metal, disposed on any surface inside the treatment tank, and a light irradiator for emitting light to the photocatalyst layer or the layer having a photocatalyst and a bactericidal metal, disposed inside and/or outside the treatment tank; placing water or a water-containing fluid to be treated in the treatment tank; generating a desired vibration between 10 and 200 Hz in the at least one vibration vane by the vibration generator to cause the at least one vibration vane to vibrate at an amplitude of 0.01 to 15 mm; irradiating the photocatalyst layer or the photocatalyst and bactericidal metal with light for 30 minutes or longer; and allowing electric current to flow for 30 minutes or longer in the water or water-containing fluid to be treated to break down, reduce, or remove halogen components in the water, and convert one or more of the nitrogen components contained in the water into nitrite ions, and sulfur components into sulfite ions, wherein the at least one auxiliary vane or a combination of the at least one auxiliary vane and at lease one component selected from a group of the vibration generator, the vibration rod, and the vibration vane-fixing member serves as an anode or a cathode.
