PROBLEM TO BE SOLVED: To provide high-speed coagulation sedimentation equipment increasing the collision number of flocks and increasing the concentration of sludge in a concentrator.SOLUTION: The high-speed coagulation sedimentation equipment comprises: a skirt plate 15 for partitioning the inside of a sedimentation basin 1 into agitation chambers 18 and 19 and a separation chamber 21; a high-speed agitator 2 for forming a circulation flow circulating between the agitation chambers 18 and 19 and the separation chamber 21; a driving device 3 for rotating the high-speed agitator 2; a low-speed agitator 30 for agitating the sludge having deposited on the bottom of the sedimentation basin 1 and carrying the sludge onto a circulating flow; a drive device 34 for rotating the low-speed agitator 30; and a concentrator 5 for depositing a flock to form concentrated sludge. |
