<P>PROBLEM TO BE SOLVED: To improve a concentration factor for a treatment target material which contains a liquid and is fed together with a flocculant, to a treatment vessel. <P>SOLUTION: A concentrator includes a draining member which is arranged in the concentration section of a treatment vessel and drains the treatment target material through rotation by rotation driving of the rotary shaft of the concentration section, which is arranged in the axial direction of the treatment vessel, and a stirring blade which is arranged in a flocculation section and rotates by rotation driving of the rotary shaft of the flocculation section arranged concentrically with the rotary shaft of the concentration section. The draining member and the stirring blade are rotated at different speeds by making the rotational seed of the rotary shaft of the concentrating section different from that of the rotary shaft of the flocculation section. <P>COPYRIGHT: (C)2012,JPO&INPIT |
