PROBLEM TO BE SOLVED: To provide an improved-type reaction apparatus for purifying a fibrous suspension dispersed in a liquid, capable of being simply produced at a low cost, and to provide a purifying method. SOLUTION: This reaction apparatus (1, 30) for purifying the fibrous suspension dispersed in the liquid is equipped with an approximately cylindrical container (2), one or more blades (3) arranged in the container, a plurality of supply units (5 to 9) for supplying the inside of the container with the suspension to be purified together with a gaseous material which is dispersed in the suspension by being formed into a bubble shape, suspension-blocking means (14, 16) arranged in the container, and a means (10) for removing/discharging bubbles and the purified suspension. Each of the supply units (6 to 9) is equipped with at least one of supply pipe (6a to 9a) on which a plurality of injectors (6d to 9d) is mounted and which extends into the inside of the container, and further each of the injectors has a spraying direction (Z) facing an inner surface (2a) of the container, for the purpose of starting to supply the suspension to be purified from an inner portion of a cross section (S) of the container.
