description PROBLEM TO BE SOLVED: To efficiently decompose and remove a volatile org. compd. by photochemical reaction treatment. SOLUTION: In the removing apparatus 100, water sprinkling nozzles 4 are arranged to the upper part of a treatment tank 1 and an ultraviolet lamp 6 is disposed to the central part of the treatment tank 1 and air nozzles 9 are arranged to the lower part of the treatment tank 1. The water to be treated sprinkled from the water sprinkling nozzles 4 becomes descending water streams while the air ejected from the air nozzles 9 becomes ascending air streams and gas-liquid contact is performed at the almost central part (in the vicinity of the ultraviolet lamp 6) in the treatment tank 1 to perform the mass transfer of the volatile org. compd. in the water to be treated from a liquid phase to a gas phase. Further, the mass-transferred volatile org. compd. is irradiated with ultraviolet rays from the ultraviolet lamp 6 to be oxidatively decomposed. By this constitution, treated water from which the volatile org. compd. is sufficiently removed is easily obtained.
