Abstract
PURPOSE: To enable the re-circulation use of primary processed water and to simplify processing of muddy water by the use of a circulation high-pressure muddy water injection pump.
CONSTITUTION: With a circulation high-pressure muddy water injection pump 3 and an air compressor started, a mixture gas, water injection pump 1 and an underwater gas feeding device 2, which are lowered by a hydraulic lifting device 13, are actuated through high-pressure hoses 8 and 9, and sediment, sand sludge in water and at the bottom is processed in a dredging amount of 0.2m3W1m3 per minute, being pumped up from a maximum depth of 200m, normally a depth of 30m. Dust in the sludge is processed by means of a dust remover 12, and earth, sand, sludge are separated by a slurry pump 10 and an earth and sand selector 7. Sludge muddy water is processed primarily, and the operation is repeated again by means of a circulation high-pressure muddy water injection pump 3. This permits dredging of the sand sludge without contaminating water quality.
