Abstract
PURPOSE: To recover high concentrations of sludge as well as to make the scale of a dehydrator small in size by using a system in which a capsule whose lower part is opened is buried in sludge layer, and sludge alone is recovered by a recovery means while sending air into the capsule.
CONSTITUTION: A capsule 1 whose lower part is opened is buried in a given sludge layers, the air-vent valve 4 of the capsule 1 is closed, air is sent into the capsule 1 from a ship, and while collecting sludge in the capusle 1 in the central portion by means of a raking plate 8, the sludge along is discharged through a hose onto the ship. After the recovery of sludge, the capsule 1 is once pulled up to water from the sludge layer S and moved to the next dredging position, the valve 4 is opened to vent air in the capsule 1, the capsule 1 is brought down to the sludge layer S, the valve 4 is closed, and the same operations are repeated.
