To provide a slurry treatment system using an active strainer which efficiently performs solid-liquid separation of slurry, generated in engineering works such as a dredge work, into soil particles and clarified water, or coagulates and precipitates the soil particles.
The active strainer 5 which has a reflection plate 12 and an ultrasonic vibrator 17a for standing wave formation so that they face each other, and is activated and stopped at the prescribed cyclic intervals by starting and stopping the irradiation with an ultrasonic wave 13, is installed in a transport passage 15 of the slurry 14. Flocs are coagulated and precipitated by the strainer, and transferred with time to perform the solid-liquid separation into the soil particles 9 and the clarified water 8. By this method, the slurry is subjected to the efficient solid-liquid separation as designed, and treated as prescribed.
