CONSTITUTION: A sludge collecting apparatus includes wedge type scrapers, connecting bodies, a driving unit(30), and guides(50A, 50B). The wedge type scrapers are arranged at the lower side of a sludge settling bath. The connecting bodies connect respect scrapers. The driving unit includes a motor. A link assembly(40) connects the driving unit and the connecting bodies and generates the reciprocating linear movement of the connecting bodies. The guide is fixed to the wall side of the settling bath and guides the linear movement by being connected with the outermost connecting bodies.
