<P>PROBLEM TO BE SOLVED: To provide a sludge treatment method which can obtain a cost advantage. <P>SOLUTION: In the sludge treatment method where organic sludge is dehydrated by a dehydrator 5 and obtained dehydrated cakes are dried by a dryer 6 to obtain dried sludge, the dehydrating condition of the dehydrator 5 and the drying condition of the dryer 6 are set so that the energy which the dried sludge has is larger than the total value of the energy supplied to the dehydrator 5 and the energy supplied to the dryer 6, and the obtained dried sludge is used as a sludge fuel. As a result, the value of the obtained sludge fuel is made larger than the total dehydrating and drying cost required to obtain the sludge fuel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
