Abstract

PURPOSE: To suppress and prevent the floating and concentrating of sludge by charging the sludge after aeration into the concentrating vessel of a sludge concentrating device provided with the sludge concentrating vessel, an inflow means for the charging sludge, a concd. sludge withdrawing means, and a separated liquid discharge means.
CONSTITUTION: The sludge flowing in through a sludge inflow pipe 2 is aerated in a sludge aerating section 16. More specifically, a gas such as air is supplied from a blower 13 through an air diffusion pipe 14, and the air from an air diffuser 15 forms bubbles, thereby aerating the sludge. The waste gas of the aeration is released into the atmosphere through a waste gas pipe 18, or is subjected to a certain deodorization treatment. Thus, the anaerobic gas is removed from the sludge by the aeration operation in the section 16. The sludge after the aeration treatment is supplied through a sludge transport pipe 19 by a sludge pump 29 into a sludge concentrating vessel 3, where it is subjected to solid- liquid separation to the settled and concd. sludge and the separated liquid.
