Quick treatment method of oily sludge

The invention provides a quick treatment method of oily sludge. The method comprises the following steps: adding a demulsification and dispersion agent to the oily sludge and performing continuous stirring to enable three-phase interfaces of oil, water and mud sand to be clear, and then, performing a sedimentation process to separate out the mud sand; adding an oxidative degradation agent to the oily sludge subjected to demulsification and dispersion treatment, performing full stirring and uniform mixing, then enabling the mixture to stand, and performing maintenance treatment for the first time to enable the oily sludge to be gelatinized; and adding an adsorption and fixation agent to the oily sludge subjected to oxidative degradation treatment, performing full stirring and uniform mixing, then enabling the mixture to stand, and performing maintenance treatment for the second time to finally obtain the oily sludge which has the oil content being 2% or lower and has certain mechanicalstrength.
