置。1. A processing tank, a hollow rotating shaft rotatably supported by the processing tank so that the upper end is outside the tank, and a plurality of nozzles provided around a side wall, and the upper end is the hollow rotating shaft. A hollow rotating body which is connected to a shaft and is located at the center of the upper part in the treatment tank, a waste water supply means for supplying waste water containing an organic halogen compound to the hollow rotating body via the hollow rotating shaft, and the hollow Rotation urging means for rotating the rotating body at a high speed together with the hollow rotary shaft, an exhaust passage having an exhaust port opening on the upper wall of the tank and communicating from the inside of the tank to the outside of the tank, and the organic halogen disposed in the exhaust passage. A packed column tower packed with an adsorbent for adsorbing a compound at an interface, and a disc-shaped baffle plate arranged so as to surround the exhaust port above the hollow rotor and below the tank upper wall. , Introduce outside air into the treatment tank, and pass through the packed column A pressure difference providing means for releasing into the air, the waste water to remove the organic halogen compound is a condensate composed of a treated waste water recovery means for recovering waste water treatment apparatus.
