<P>PROBLEM TO BE SOLVED: To provide a measurement tank which is of a simple structure and has a flocculation function. <P>SOLUTION: On the measurement tank 1, a flow path 10 in which liquid U to be treated and flocculant solution C are blended and agitated is formed. The flow path 10 is formed in a zigzag manner by a barrier 13 provided to be shifted alternately to the right and left of an inner wall thereof. On the floor surface and the top surface of the inner wall of the flow path 10, and on the surface of the barrier 13, a plurality of substantially conical projections 14 with pointed surfaces thereof removed are formed. The projections 14 are formed by extruding the barrier 13 from the rear side. The projections 14 on the floor face and the top face of the flow path 10 are also formed in the same manner. The liquid U to be treated and the flocculant solution C pass through the zigzag-shaped flow path 10 formed by the barrier 13 and the projections 14, thus achieving highly efficient and uniform blending, agitating and reaction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
