A process liquid waster treatment apparatus is provided to separate a processing piece from the processing liquid waste by injecting the fine power to a filter bed with a cylindrical shape of a filter. The processing liquid waste is received in a liquid waste tank(2). A pump(3) transfers the liquid waster from the liquid waste tank. The filter filters the transferred process liquid waste. The filter is composed of a filter bed with a cylindrical shape, a bottom plate(43), and an upper plate(44). A cylindrical body covers the circumference of the filter bed. A plurality of openings are formed in the side of the cylindrical body. A liquid waste input unit(441) is formed in the upper plate. The fine powder(40) is injected to the filter bed.
