SLUDGE DEHYDRATION METHOD AND SLUDGE DEHYDRATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a sludge dehydration method capable of effectively reusing removed sludge. SOLUTION: This method is used in a vacuum-precoat-type dehydration treatment using a rotary drum. In this method, the surface layer of sludge adsorbed by a precoat layer and sludge penetrating into the precoat layer are simultaneously cut separately, and each sludge cut separately is recovered separately.
