(57) [Abstract] [Purpose] To provide a sludge water solid-liquid separation device which is not clogged and has a long life. [Configuration] A large number of fixing rings 6 are arranged with a gap, In the meantime, while arranging the floating ring 30 in a movable state, While rotating the screw conveyor 31 provided in the internal space S of the fixed ring 6 and the floating ring 30 to convey the sludge water introduced into the space S by the screw conveyor 31, only the water content thereof is moved to the floating ring 30 and the fixed ring 6. Is discharged to the outside through the small gap g between the floating ring 3 and The movement of 0 prevents the minute gap g from being clogged with solids. |
