摘要： A sludge treatment process including: adjusting sludge to a particle diameter of more than 2 mm to 45 mm or less; a step of pyrolyzing the adjusted sludge in a low-oxygen or oxygen-free atmosphere and at a temperature of 350° C. to 500° C.; and a step of combusting a gas generated in the pyrolysis. Such process may be used to decompose harmful compounds and maximize the efficiency of the process.
