Progress in Shale Oil Refinery Waste Water Treatment Technology

Shale oil refinery waste water was a kind of high-concentration organic waste water with many types of pollutants and complex components. It contained environmental pollutants such as petroleum, volatile phenols, organic nitrogen, naphthenic acid compounds and fused ring aromatic hydrocarbons. If it is discharged directly without treatment, it will cause serious harm to the environment, and it must be treated before it can be discharged. At present, the treatment methods of shale oil refinery waste water mainly include physical treatment, chemical treatment, physical and chemical treatment and biological treatment. This paper studied the treatment technology of shale oil refinery waste water.
