Abstract
An oil-bearing sludge processing method includes the steps of bringing a processing agent having calcium oxide as its main component into contact with oil-bearing sludge to cause a reaction between a water component of the oil-bearing sludge and the calcium oxide in the processing agent, thereby partially volatizing, dispersing and removing oil component by heat from the reaction and forming porous calcium hydroxide produced by the reaction in a form of a powdery and granular material that has adsorbed the oil component and has been covered with a calcium carbonate layer. The material does not leach out the oil component and is used as a soil fertilizer, a combustion accelerator, a construction material, a road material, etc.
