The oily sludge belongs to hazardous waste,which is difficult to degrade and harmful to the environment and human body.Furthermore,it is one of the research focuses of scholars at home and abroad.At present,the traditional treatment methods have problems such as large residue,incomplete treatment,and easy formation of secondary pollution.In contrast,hydrothermal technology is an efficient and promising harmless treatment technology for hazardous waste,which will further promote the harmless treatment of oily sludge.This paper reviews the research status of oily sludge treatment in China and abroad,the research progress of oily sludge hydrothermal oxidation treatment technology,and the mechanism of petroleum compounds conversion in subcritical/supercritical water,in order to provide a reference for the gradient hydrothermal recovery of oily sludge.
