Abstract

PURPOSE: To separate dredged slurry into solids and liquid and discharge water processed to high quality by introducing the slurry into a sedimentation area, thickening and accumulating solids in the sedimentation area by sedimenting, and filtering the separated spilling water with long hair filter cloths.
CONSTITUTION: The spilt water from the primary stage of sedimetation processing including low concentration suspended solids which flows out of a sedimentation area, is introduced into a long hair filter 12 through a pipe 13, and is separated into solids and water. The separation is carried out to the SS concentration of less than 10 ppm and the filtered water is discharged from a processed water pipe 21. The solids in the form of slurry are introduced into a long hair filter 18, separation is carried out again, and filtered water is discharged from a processed water pipe 20. The solids caught by the long hair filter 18 are introduced into a thickener 25 through a mud discharge pipe 24 and sedimenting separation is carried out again. The supernatant fluid of the chickener is mixed with the spilt water from a pipe 9 and processed again, and the solids are returned to a sedimentation area 1 through a mud discharge pipe 27 and sedimented.
