[ What is claimed is:] [1.]1. A water purification apparatus for purifying water containing an organic matter, comprising:an oxidation processing reservoir for holding water comprising an inorganic coagulant and catalyst particles and for flocculating said catalyst particles;means for activating said catalyst particles inside said oxidation processing reservoir, wherein said catalyst particles comprise a photocatalyst and said catalyst activating means comprises means for emitting light;a separation reservoir for separating the flocculated catalyst particles from the waters means for controlling the pH within said separation reservoir; andmeans for maintaining the diameter of the flocculated catalyst particles in the water in said oxidation processing reservoir to be equal to or less than 0.1 mm, wherein said particle diameter maintaining means comprises means for controlling the pH in the water in said oxidation processing reservoir.
