To provide an apparatus and a method setting a position of a slurry filtering means according to a suspension state or level of slurry in a slurry storing tank, and efficiently dewatering slurry.
This slurry filtering means is provided with the slurry storing tank 11 storing slurry, and a slurry filtering apparatus 12 filtering the slurry in the slurry storing tank. The slurry filtering apparatus 12 is provided with a filtering body 13 having a filter 13C, and a depressurizing means 14 depressurizing the inside of the filtering body and sucking and filtering the slurry to discharge filtrate to the outside. The filtering body 13 is connected to floaters 15 (floating means), and suspendedly set in the slurry, being supported by the floaters 15. In the dewatering apparatus and dewatering method of slurry, wires 21 suspending the filtering body 13 and a winch 22 winding the wires 21 are preferably set to the floaters, and the suspending position of the filtering body is variable by adjusting the length of the wires.
