SLUDGE TREATMENT METHOD AND CEMENT PRODUCTION SYSTEM
A sludge treatment method includes: preparing a mixture by mixing dehydrated sludge and cement raw meal; drying the mixture by a dryer that brings the mixture into contact with drying gas; supplying the dried mixture to a pyroprocessing step of a cement production process as a fuel and raw meal; supplying exhaust gas from the dryer to the pyroprocessing step as cooling gas for cooling a pyroprocessed product; and supplying the drying gas to the dryer, the drying gas being either exhaust gas from the cement production process or exhaust gas from a process that utilizes heat thereof, the drying gas having a temperature of not lower than 50°C but lower than 200°C.
