CLARIFICATION OF TURBID WATER IN DREDGING BOTTOM OF DAM, LAKE OR THE LIKE

摘要

PURPOSE:To perform the clarifying treatment of turbid water, when a dam, lake, swamp or the like is dredged, by treating the turbid water containing sediment with the combination of a crude water vessel, a coagulating vassel, a constructional frame, a sediment/turbid water separator, a dehydrator, a floating vessel for collecting turbid water, etc.. CONSTITUTION:Turbid wate containing sediment, which is sucked up on the water surface by dredging the bottom of a dam, lake or the like, is treated with the combination of a purge pump, a purge, a crude water vessel arranged under the water or on the water, a coagulating vessel, a constructional frame surrounding these members for fixing them and acting as a work scaffold, a sediment/turbid water separator arranged on the land or the water, a dehydrator, a floating vessel for collecting turbid water, a tugboat, a hose, a pump, a barge as a base for a crane, a command-commucication means, etc. The clarified water after the treatment is returned to the dam, lake or the like. In order to perform the clarification with high effeciency, a flocculant which offers an effective result shall be selected by a cylinder test or the like.
