COMPLEX DEHYDRATION APPARATUS

摘要

PURPOSE: A complex dehydration apparatus is provided to automatically improve driving efficiency, and to reduce the amount of medicine input and percentage of the water content while improving sludge processing efficiency. CONSTITUTION: A complex dehydration apparatus comprises a dehydration unit including a centrifugal dehydrator(30) and a controller(50), and a sludge pre-processing unit(10). The centrifugal dehydrator separates sludge into cake and filtrate with centrifuge. The sludge pre-processing unit pre-processes the sludge before supplying the sludge to a dehydration unit. The sludge pre-processing unit includes a limewater feeder(11) or a crusher(15). The centrifugal dehydrator includes a bowl(31), a scroll(33), a driving motor(32), and a sub-motor(38). The dehydration unit further includes a sludge supplier(20A) and a polymer inputting unit.
