PURPOSE:To obtain a treated fluid of high quality which does not contain an organic material, a bacteria, a harmful material or the like by efficiently executing photochemical reaction treating to the fluid under presence of a photo- catalyst by light irradiation. CONSTITUTION:In photochemical reaction treating such as oxidative decomposition of the organic material, sterilization of the bacteria and decomposition of the harmful material executed under the presence of the photocatalyst in which anatase type titanium or the like has a large contact area and which has a shape excellent in passability by irradiation of a light such as ultraviolet ray or sunlight, photochemical reaction treating is accelerated by adding an oxidizing agent such as BrO3 into the fluid. |
