A general system for treating dredged sediments is provided to decrease a dredged sediment-treating process, prevent environmental contamination and to recycle sand separated from the dredged sediments. A general system for treating dredged sediments includes a latticed screen with coarse openings(10), an inflow tank(20), a spindle-less screw conveyor(30), a drum screen for cleaning and separation(40), and a grit washing unit(70). The latticed screen with coarse openings screens the dredged sediment. The inflow tank is installed at a lower part of the screen. The grit washing unit includes an inflow part(72), a washing tank(74), a vent(73), and a sand transfer unit(79). The dredged sediments treating system includes an adulteration carrying-out conveyor(50), a grit pit(60), a level sensor(62) for the grit pit, a grit transfer pump(64), a treated water pit(80), a level sensor(82) for processing water pit, and a processing water feed pump(84). |
