A water purification apparatus for purifying an organicnmatter(s) contained in raw water by oxidization thereof with usenof a catalyst, in particular photo-catalyst, such as titaniumndioxide, comprising:n an oxidization processing reservoir (1, 12) for reservingnthe raw water, into which is added an inorganic coagulant and isndispersed with particles of the catalyst; a light source (2) for emitting ultraviolet ray lights insidenthe oxidization processing reservoir so as to activate thencatalyst; a separation reservoir (8, 12) for separating from the rawnwater the catalyst particle by condensing with electrochemicalnfunction of the inorganic coagulant; and a pH adjuster(s) (11, 6) for maintaining the catalystnparticles dispersed in the raw water within the oxidizationnprocessing reservoir to be equal to or less than 0.1 mm in diameternthereof. |
