ABSTRACT:
The sludge treatment system is comprised of a dam passage penetrated through a dam (D); an induction pipe (11) for discharging a sediment retained by the dam (D) and having an inlet (11a) toward the floor of the dam (D) and an outlet connected to an inner end of the dam passage; an induction force action pipe (13) connected to an outer end of the dam passage and extended in a height for utilizing an atmospheric pressure as an induction force of the sediment; a U shape air control pipe (14) connected to the induction force action pipe (13), and preventing for an air from coming into the induction force action pipe (13); a drain pipe (15) connected to the air control pipe (14) for discharging the sediment; and an air vent pipe (16) connected to a horizontal flat portion of the air control pipe (14) for dissipating the induction action of both the air control pipe (14) and the drain pipe (15).
