<p><P>PROBLEM TO BE SOLVED: To generate flocculated matter by efficiently mixing turbid water to be treated and a flocculation material, and to facilitate sedimentation and separation of the generated flocculated matter in order to make the discharge water that satisfies the water quality standard of the place where the water is discharged. <P>SOLUTION: The turbid water treatment apparatus includes: a flocculation material supply device 70 which supplies a flocculation material into the water to be treated; a rapid agitation tank 10 which generates flock by stirring the water to be treated in which the flocculation material is supplied; a slow agitation tank 20 which facilitates the growth of the flock by stirring the water to be treated flowed out of the rapid agitation tank 10 at a speed slower than that of the rapid agitation tank 10; a precipitation tank 30 which precipitates and removes the flock in the water to be treated flowed out of the slow agitation tank 20; and a solid-liquid separation tank (the first solid-liquid separation tank 40 and the second solid-liquid separation tank 50) having a filtration device (rotary drums 100 and 110) which generates discharge water by separating the flock which is not removed at the settling tank 30 through filtration. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
