Abstract
PURPOSE: To dehydrate a part or large parts of contained water in sludge and to concentrate by a simple means in a short time, by settling nonwoven fabric covered the surface of sludge liquid of the sludge dehydrator introduced the sludge and discharging clean water permeated and filtrated on the upper face of the nonwoven fabric.
CONSTITUTION: The nonwoven fabric 2 is provided on the upper face of the sludge A so as to cover said face and the suction hose 4 of the discharge pump 3 is placed on the fabric 2, after introducing the sludge A having about 99.8W95% water content produced by water treatment in the sludge dehydration vessel 1. Then, the fabric 2 is slowly settled down in the sludge A by the empty weight of impregnated fabric 2 and hose 4 and at this time, water of the sludge A is permeated and filtered by the fabric 2 and the clean water B is obtained on the settled nonwoven fabric 2a. Further, the water B is discharged from the suction hose 4a extending downward accompanied by the settlement of the fabric 2a. When the clogging is brought about by sticking the solid matter S of the sludge A to the lower face of the fabric 2 together with the settlement of the fabric 2a and the settlement of the fabric 2 is stopped, the fabric 2 taken out and concentrated fluidizing sludge A is discharged 5 from the lower part of the vessel 1 and then, is sent out for the sludge treatment.
