Novel oily wastewater treatment system

The utility model belongs to the technical field of sewage treatment, and particularly relates to a novel oily wastewater treatment system which comprises a separation tank, an oil separation tank, vertical air flotation equipment and an auxiliary treatment system. Aiming at the difficulty in removing the dispersed oil in the oil-containing wastewater, on the premise of combining a common water purification technology, the vertical air floatation equipment is subjected to rotational flow improvement, the micro-nano bubble device is used for spraying bubbles to dissolve air, and the dispersed oil is removed by adopting a micro-nano bubble technology, so that the purification effect meets the set requirement; meanwhile, a follow-up auxiliary treatment system is used for auxiliary treatment, finally, purification treatment of the oily wastewater is completed, and the oily wastewater is discharged after the water quality reaches the first-level A dischargeable standard. 本实用新型属于污水处理技术领域，具体涉及一种新型含油废水处理系统，包括分离槽、隔油池、
