Sludge treatment device

The invention relates to the field of riverway desilting, and discloses a sludge treatment device which comprises a mud-water separation component and a sludge box, and the sludge box is clamped to one end of the mud-water separation component; a silt suction component is arranged at one end, away from the sludge box, of the outer surface of the sludge-water separation component; the silt suction component is used for sucking silt, flushing the silt in the river channel and conveying the sucked silt into the mud-water separation component; the mud-water separation part is used for carrying out solid-liquid separation on the collected sludge, collecting the filtered water and providing a water source for flushing the sludge for the sludge suction part; according to the dredging device, the silt suction component and the mud-water separation component operate in a matched mode, silt can be sucked, mud and water can be separated, meanwhile, water resources can be recycled, use of a large number of water pipes an
