The invention discloses a method and a device for processing ethylene oxide waste gas. The method comprises the following steps: step one, employing a vacuum pump to pump the sterilized ethylene oxide waste gas into a chemical combination apparatus for carrying out a chemical combination reaction with concentrated sulfuric acid to produce ethylene glycol, and regularly discharging ethylene glycol to be used as an industrial raw material; step two, allowing remaining ethylene oxide gas to go into a turbulent ball chemical combination tower under the action of a gas-liquid pump, and further carrying out hydration degradation with an aerated water flow of 85-95 DEG C in the turbulent ball chemical combination tower; and step three, allowing hot water discharged by the turbulent ball chemical combination tower to flow into an aeration tank to carry out aeration oxygenation and the like. The method and the device are suitable for harmless treatment of the ethylene oxide waste gas in a large-scale disinfection cent
