SLUDGE TREATMENT FACILITY AND TREATMENT METHOD

摘要

In the present invention, sludge is treated by means of a sludge treatment facility (100) using a cement plant (200). The sludge treatment facility (100) is provided with: a dryer (1) that dries dehydrated sludge; a dried sludge conveyance device (3) that conveys the dried sludge that has been dried by the drier to a calcination furnace (35) and/or a firing furnace (for example, a rotary kiln (40)) for cement starting materials; and a drier exhaust gas conveyance device (4) that conveys the exhaust gas from the drier (1) to the dust collector (66a) of the exhaust treatment device (66) of a cement starting material mill (65). The dust collection process for the exhaust gas from the drier is performed by means of a dust collector (for example, a bag filter (66a)) of the exhaust treatment device (66) of the cement plant.
