A sludge concentrating apparatus (20) with simple piping arrangement, comprising a tank (5) having a sludge vessel (8) and a reaction vessel (7) isolated from each other by means of a bulkhead (6); an air pump (22) for pressurizing or depressurizing the interior of the tank (5); a suction/discharge operating valve (25) for communication or cutoff between the air pump (22) and the tank (5); a vessel switching valve (45) for communication between a sludge suction pipe (51) for suctioning of raw sludge water and either the sludge vessel (8) or the reaction vessel (7); and a sludge treatment valve (54) for communication between the sludge vessel (8) and the reaction vessel (7). The sludge vessel (8) thereinside is provided with a drum screen (11) for separation of sludge contents from sewage water suctioned from the reaction vessel (7) into the sludge vessel (8).
