Description

technical field

[0001] The invention relates to the technical field of garbage disposal, in particular to a method for treating oily sludge. Background technique

[0002] Oily sludge mainly comes from oil exploration, refining and petrochemical industries. With the increase of oil production, the total amount of oily sludge produced is also increasing, and the pollution to the environment is becoming more and more serious. Therefore, whether it is from the perspective of environmental protection, maintenance of normal production or from the perspective of energy recovery, it is necessary to carry out harmless and resourceful treatment of oily sludge.

[0003] At present, the harmless treatment of oily sludge is mainly: oily sludge is heated by microwave under anaerobic conditions and treated by thermal cracking technology, thereby improving the recovery rate of oil and gas resources in oily sludge, reducing environmental pollution and improving economic benefits. . [0004...
