Claim 13:
14. A bacteria treatment method comprising:
an initial decontamination process of supplying a decontamination treatment fluid generated by a decontamination treatment fluid supply unit to an air supply duct via an air filter that is provided between the decontamination treatment fluid supply unit and a bacteria treatment unit in the air supply duct and removes at least one of the dirt and dust in a fluid passing through the air supply duct during initial decontamination of the air supply duct;
an initial air supply process of supplying air to the bacteria treatment unit via the decontamination treatment fluid supply unit and the air filter in the air supply duct by an air supply fan that is provided at an air supply port of the air supply duct;
an initial decomposition process of decomposing a fluid containing the decontamination treatment fluid exhausted from the bacteria treatment unit with a catalyst and releasing the fluid to the outside air;
a bacteria treatment process of irradiating the bacteria treatment unit with radiation to perform bacteria treatment of an object;
an aeration process of supplying air to the bacteria treatment unit through the air supply duct after the bacteria treatment, and exhausting the fluid in the bacteria treatment unit;
a decomposition process of decomposing the fluid in the bacteria treatment unit exhausted from the bacteria treatment unit with the catalyst or another catalyst and releasing the fluid to the outside air; and
a take-out process of taking-out the object from the bacteria treatment unit after the decomposition process,
wherein the decontamination treatment fluid flows in an order of the air supply duct, the bacteria treatment unit and an exhaust duct that exhausts molecules in the bacteria treatment unit by an air supply from the air supply fan.
