Title: Sludge treating method using carbonized sludge
Inventor: MIWA HIROAKI
IPC: C02F11/14
Filed: 2000-06-13
Abstract: PROBLEM TO BE SOLVED: To improve water quality and to improve the treating capability in a thickener and final settling basin by using carbonized sludge as a flocculation assistant in a sewage disposal process. SOLUTION: The settled sludge scraped to a sludge pit 18 of the final settling basin 14 is transferred as excess sludge through a first sludge pump 22 into an agitating box 28 in the thickener 24. At this time, the carbonized sludge supplied from a carbonization furnace device 40 to a feeder 30 is simultaneously supplied to the agitating box 28 in proportion to the inflow rate of the excess sludge. The excess sludge, when flowing into the agitating box 28, induces swirling flow, thereby rising the excess sludge and the carbonized sludge in the agitating box 28 under agitating and mixing, until the excess sludge and the carbonized sludge enters a flow regulating cylinder 28. Both are then thickened by gravity settling on the bottom of the thickener 24.  Since the grain size of the sludge gravity settling in the thickener 24 is large, the settling property thereof is high and the settling and thickening progress efficiently.
