1. A sterilization method which comprises:
- adding ozone to a gas containing microorganisms;
introducing the resulting ozone-containing gas into a discharge zone so as to produce plasma in the gas; and
supplying the resulting treated gas into a catalytic reaction zone at ordinary ambient temperature such that a gas which is substantially free from ozone and microorganisms is obtained.

Abstract
A waste gas in treated by the sequence of discharge treatment and catalytic oxidation. A microbe-containing gas is disinfected by first mixing it with ozone, then subjecting the gas to discharge treatment and catalytic reaction successively.

6. A sterilization method which comprises:
- performing surface sterilization in working space by supplying ozone thereinto;
after completion of the surface sterilization, drawing the ozone-containing gas from the working space and introducing it into a discharge zone so as to produce plasma in said gas;
supplying the resulting treated gas into a catalytic reaction zone at ordinary ambient temperature such that a gas which is substantially free from ozone is obtained; and
returning said ozone-free gas to said working space.
- performing surface sterilization in working space by supplying ozone thereinto;
- 7. A method of treating a noxious component in a waste gas by oxidation which comprises first introducing the waste gas into a discharge zone to form a plasma-containing gas and then introducing said plasma-containing gas into a catalytic reaction zone so as to allow said noxious components to enter into a catalytic oxidation reaction.
