NOVELTY - Circulating water (4) and ozone are supplied to a horizontal ejector from storage tank (3) and the ozonizer respectively. The ozonized water is then reacted with the odorous gas supplied from the nozzle (14). The water gets separated, drops into the tank, and the treated gas is ejected outside.    USE - For deodorizing odor gas in organic refuse processing apparatus.    ADVANTAGE - Enables efficient deodorization of odorous gas. Apparatus structure is simplified. Enables uniform maintenance of the temperature of circulating water. Enables repeated usage of the circulating water, and therefore reduces the running costs.    DETAILED DESCRIPTION - The circulating water and the ozone are supplied to the ejector from the storage tank and the ozonizer. The ozonized water is then reacted with the odorous gas supplied from the nozzle, to separate and discharge water into the tank and eject the treated gas outside. The water is supplied to the horizontal ejector at the upstream side of the primary venturi portion (8). The temperature of the circulating water in the tank is uniformly maintained, even when the high temperature odor gas is discharged from nozzle into the tank. The connection portion of the horizontal ejector (5) with the vertical ejector (6) is made larger than the circulating water inlet (7) and the primary venturi downstream portion.    An INDEPENDENT CLAIM is included for deodorizing apparatus which has ejectors above the circulating water tank. The internal diameter (c) of connection portion (9) is larger than the internal diameter (D) of the ejector (6). The diameter (E) of discharge portion (11) of ejector (6) is equal to the internal diameter (B), diameter of primary venturi downstream portion (8a) and the internal diameter (A).
