Abstract
PURPOSE: To enable an addition of a flocculant by a method wherein an area for dredging by buckets is surrounded by a protective wall to prevent the outflow of muddy water, a device for the treatment with a flocculant is disposed outside the wall, and muddy water inside the wall is introduced into the device.
CONSTITUTION: A protective wall 2 is arranged around a dredging area by buckets 4, and a flocculating device 3 is arranged outside the wall 2. Charged with muddy water 5 from the inside of the wall 2, the device 3 adds a flocculant to the muddy water to cause flocculation of mud contained in the muddy water. For instance, an inorganic flocculant such as aluminum sulfate, ferric sulfate, and ferric chloride, or an organic polymeric flocculant such as polyacrylamide and polyoxyethylene glycol is used as the flocculant-precipitant. The use of an organic polymeric flocculant is more preferable.
