Disclosed is a method and apparatus for treating water containing soluble COD components, which can sufficiently remove soluble COD components more than when powdered activated carbon is used. After adding a particulate COD component removing material to raw water, an inorganic flocculant, an organic flocculant, or an organic polymer flocculant is added and agglomeration treatment is performed, followed by solid-liquid separation. The COD component removing material is preferably an ion exchange resin, has an average particle diameter of 1 to 200 μm, a specific surface area of 0.05 to 20 m 2 / cm 3 , and an addition amount of 0.1 to 5 g / L. is there.
