PURPOSE:To efficiently treat sludge containing a high moisture content, by a method wherein dried sludge and sludge not passing through a drying process, are mixed together by a mixing device to feed it to an incinerator. CONSTITUTION:A temperature signal from a furnace temperature transmitting device 28 is fed to a control box 21 providing memory and an instruction signal, and in response to an instruction from the control box, drive motors M19 and M20 for sludge feed screw of a set of sludge feeders 19 and 20, respectively, are controlled, and a feed amount of sludge is controlled. A signal 22, controlling a feed amount of undried sludge 16 by means of the contrl box 21 according to a change in the temperature of a furnace, is sent to the sludge feeder 20 to control a feed amount. A moisture meter is provided with a device 200, a device 216 located on a line for an undried sludge 16, a device 203 situated on a line for a dried sludge 3, and devices 219 and 220 positioned at the outlets of the sludge feeders 19 and 20, and the signal is fed to the control box 21. This permits efficient treatment of sludge containing a high moisture content.
