Abstract
PURPOSE: To perform removal of sludge and algae stuck on multiple stages of horizontal sludge settling acceleration plates and prevention of their sticking by irradiating ultrasonic waves to said plates.
CONSTITUTION: When an oscillator 8 is moved on a settling basin 1 by the combination of a traveling carriage 5 and a carriage 6, and settling acceleration plates 2 are moved uniformly, the oscillator 8 connected to an ultrasonic oscillator 7 moves while irradiating ultrasonic waves in a downward direction from said oscillator above the plates 2. At this time, the sludge and algae stuck on the plates 2 are stripped by the irradiation of ultrasonic waves to the plates 2. Further, the stripped sludge is pushed by the velocity of flow and is removed successively in such a way as to spill down gradually from the down flow ends in the down flow direction of the plates 2. The sludge removed from the plates 2 settles into a hopper 3 in the lower part by gravity, from which it is withdrawn and removed.
