Abstract
PURPOSE: To enhance a separation efficiency of a fine powder coal by a method wherein a crude particulate coal containing a binder adhered to a surface thereof is filled in a filter tank and a waste water containing a fine powder coal is passed through said tank.
CONSTITUTION: A packed layer 3 comprising a crude particulate coal containing a binder such as a heavy oil or the like adhered to a surface thereof is provided in the filter tank 1. A waste water containing a fine powder coal is introduced from a supply pipe 2 to be passed through the packed layer 3. The fine powder coal in the waste water is adhered to the binder on the surface of said crude particulate coal of the packed layer 3 as a nucleus to be taken thereinto and, thereby, the waste water is converted to clarified water. Further, the waste water may be introduced from an upper part, a lower part or an intermediate part of the packed layer 3. Moreover, the packed layer may be provided in multiple stages.
