The oily sludge has a wide range of sources and complex composition, the corresponding treatment technology and equipment also show a diversified trend, after the combined treatment of oily sludge, the oily sludge can meet the technical requirements of resource utilization and harmless treatment. Through the actual and literature research, the principle, scope, characteristics and development of the commonly used oily sludge treatment methods at home and abroad are summarized, the application status of several new oily sludge combined treatment technologies in China’s petrochemical enterprises is introduced, including sieving fluidization-tempering-mechanical dehydration technology, electrochemical bio-coupling advanced treatment technology, sludge centrifugal dewatering-superheated steam injection treatment technology, hot-washing coupling treatment technology and microbial-plant combined treatment technology, summarized whether the oil content of the residue after treatment by the existing treatment method meets the standard requirements of HJ 607-2011 “Technical Specifications for Pollution Control of Used Mineral Oil Recovery, Recycle and Reuse” and the resource utilization of the residue goes. The problems and treatment effects of the integrated oil sludge treatment technology in application have not yet been treated in a satisfactory manner to completely treat all oily sludge, and further research is needed.
