Summary:The invention relates to a pine gum deep processing wastewater treatment method, which comprises that waste oil is separated and recovered from wastewater by an oil-water separation and recovery device; the obtained wastewater enters a cavitation air flotation device, 50-80 ppm of a coagulant and 3-10 ppm of a coagulant aid are respectively and sequentially added to the wastewater, and the waste residue in the wastewater is separated and recovered; the treated wastewater enters a middle tank, and the water amount and the water quality of the wastewater are adjusted; and the obtained wastewater is sucked into an oxidation tower under the action of a sewage lifting pump, and the wastewater is subjected to oxidation treatment by an ozone generator connected to the oxidation tower, such that the wastewater can be discharged after the wastewater achieves the discharging standard. According to the present invention, the method has advantages of short process, stable and reliable treatment effect, stable and reliabl
