Flocculation basin in water treatment process |
摘要 |
The fluidizing speed of water inside a flocculation basin of a water treatment process plant is adjusted in accordance with the state of flocculation inside the flocculation basin. The state of flocculation is determined by taking a plurality of pictures within a predetermined period by an ITV disposed inside the basin, recognizing a sufficiently large number of flocs from the pictures thus taken, calculating the particle diameters of the flocs and determining the particle diameter distribution from the result of calculation. The judgement signal is used as a signal for adjusting the water fluidizing speed.
