The present invention relates to a water treatment device in which a nanotube type catalyst fixed to a titanium support rotates alone. The purpose of the present invention is to provide a water treatment device in which a nanotube type catalyst fixed to a titanium support rotates alone so that excellent photochemical reaction is performed in a reactor by using, as a medium, a nanotube structured titania (TiO_2) optical catalyst, which is autonomously grown on the surface of a mesh type titanium (Ti) support through anodizing and heat treatment, so as to overcome the weaknesses of a particle type optical catalyst reacting system. The water treatment device in which a nanotube type catalyst fixed to a titanium support rotates alone according to the present invention comprises: an optical reactor of which the top and bottom sides of one side surface connect with an outlet pipe path and an inlet pipe path, respectively, and which includes a housing having a cylindrical shape of which the top part is opened; an optical catalyst installed inside the housing to be able to rotate with a rotation means as a medium and in which a nanotube titania is formed, which is obtained as the surface of a mesh type metal titanium support is anodized and integrated; a water tank in which hexavalent chromium and aqueous solution having an adjusted concentration of hydrogen ions, which are needed to react the optical catalyst, are stored and which connects with the housing through the outlet pipe path and the inlet pipe path; and a light source part irradiating ultraviolet rays to the side of the optical reactor so that the ultraviolet rays react with the optical catalyst and the hexavalent chromium is reduced. |
