摘要： Provided is a solid-liquid-separation processing method in which solids in a slurry are separated and removed by applying multistage washing to the slurry, in which, even in the case where the number of connected thickening-apparatus stages is smaller, the clarity of obtained supernatant liquid can be improved. In the solid-liquid-separation processing method in which thickening apparatuses each equipped with an agitation tank and a sedimentation tank having an overflow unit in a peripheral portion thereof to discharge supernatant liquid and a cylindrical feed well vertically arranged at a central portion thereof are provided in multiple stages, and multistage washing is applied to a slurry to separate solids in the slurry therefrom and obtain a solution from which the solids are removed, when a flocculant configured to flocculate the solids in the slurry is added, a predetermined proportion of the flocculant is added to a feed well in a first-stage thickening apparatus, and the remainder of the flocculant is added to an overflow unit in a second-stage thickening apparatus.

摘要： The invention provides a flotation device including a thickening tank (1) having rightcylindrical sidewalls and a downwardly sloping frusto-conical floor. A drive shaft (2) is centrally rotatably mounted within the tank. Each one of a plurality of rake arms (3) is fixedly connected to the drive shaft and extends radially outwardly, substantially parallel to the tank floor. Each arm supports an array of blades (4) extending axially into the tank. An array of baffles in the form of rectilinear baffle plates (5), fixed relative to the tank, extends axially into the tank in complementary alternate radially spaced relationship with the blades (4). The baffle plates are located within the swept volume of the blades to retard fluid rotation in response to the rotation of the rake. A diametrical service bridge (6) is fixedly connected to the tank for mounting the baffle plates.
