| description | The invention relates to a petroleum wastewater treatment method, and belongs to the technical field of wastewater treatment.The petroleum wastewater is subjected to advanced treatment after being pretreated, the pretreatment process comprises a primary precipitation process, a primary flocculation process and an air flotation process, and the advanced treatment process comprises a bioreactor treatment process and a post-treatment process. The bioreactor treatment process is to treat the petroleum wastewater in a bioreactor by using a bacterial colony co-cultured by a biosurfactant and petroleum degrading bacteria. Petroleum wastewater is treated through biochemical reaction, the biochemical oxygen demand (BOD) can be reduced by 95-99%, the chemical oxygen demand (COD) can be reduced by 95-98%, the biochemical capacity of microorganisms is remarkably improved, and the petroleum wastewater treatment effect is better.
