PAPERMAKING SLUDGE PROCESSING METHOD AND PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a hardened body having high density in mass production level. SOLUTION: Papermaking sludge separated from pulp 84 by a water washer (80) is dehydrated by a screw press 92 to produce a block-like papermaking sludge 11B. Water is added to the block-like papermaking sludge 11B to adjust the consistency and then sheet-making is effected by using filtered water. That is, dehydrating the papermaking sludge separated in a paper mill makes it easier to transport the papermaking sludge to a papermaking sludge processing facility provided with filtered water; thus, a hardened body can be produced from papermaking sludge in a commercially profitable manner.
