  • Patent number: 9498549
    Abstract: A sterilization method and sterilization processing apparatus having a high sterilization effect and capable of shortening a sterilization time are provided. An electrolysis apparatus 2 electrolyzes water in a reservoir 1 and generates strongly acidic electrolytic water in an anode chamber 11 and generates strongly alkaline electrolytic water in a cathode chamber 12. A first wash container 3 is provided with a drain having an on-off valve and retains the strongly alkaline electrolytic water in the cathode chamber 12. A second wash container 4 is hermetically sealable, provided with a drain having an on-off valve and retains the strongly acidic electrolytic water of the anode chamber 11. A gas jetting apparatus 5 has a collector pipe 51 communicating with the inside of the second wash container 4 and causes air or a chlorine gas collected from the inside of the second wash container 4 through the collector pipe 51 to jet in the strongly acidic electrolytic water inside the second wash container 4.
