Claim:
1. A fluid-forwarding sludge-discharge device for settlement basin which moves sludge settled on a bottom of the settlement basin to a sludge-receiving unit formed at a central part of the bottom, comprising: a pressurized water-spraying unit which sprays pressurized water to the sludge settled in the settlement basin to move the sludge to the sludge-receiving unit while one end of the pressurized water-spraying unit is positioned adjacent to the bottom of the settlement basin; a sludge suction cover which is in the form of box with an open lower end and is disposed on the bottom so as to cover an upper part of the sludge-receiving unit, wherein a sludge inflow recess is formed through a side surface of the cover and thus the cover guides the sludge moved by the pressurized water-spraying unit so that the sludge flows in through the sludge inflow recess and thereafter moves to the sludge-receiving unit; and collection guide plates which are disposed on and joined to the bottom of the settlement basin and guide the sludge moved by the pressurized water-spraying unit so that the sludge flows into the sludge inflow recess, wherein a plurality of the sludge inflow recesses are formed in the side surface of the sludge suction cover while being spaced apart from each other, wherein the collection guide plates are disposed on and joined to the bottom of the settlement basin to divide the bottom into a plurality of sections, while being positioned between two adjacent sludge inflow recesses, and wherein an end of each collection guide plate facing the sludge suction cover is positioned adjacent to an outer surface of the sludge suction cover.
