METHOD OF CONCENTRATING AND DEHYDRATING SLURRIED SLUDGE.

摘要

A method of efficiently concentrating and dehydrating slurried sludge in a short period of time without requiring a wide area. In an agitating tank, the sludge containing a flocculant is agitated and turned into an aggregate; the aggregate and supernatant water in the agitating tank are fed to the upper part of the inlet side of an endless moving filter cloth of an endless moving filter type dehydrator comprising a dehydrating tank and an inclining endless moving filter cloth disposed in the dehydrating tank; the aggregate thus fed is placed on the endless filter cloth, continuously displaced toward the outlet side of the filter cloth, concentrated at a part under which the filter cloth is positioned to lie in the supernatant water in the dehydrating tank, and dehydrated at a part under which the filter cloth is positioned to lie above the level of the supernatant water in the dehydrating tank.
