[0002] In the field of sewage treatment, especially the treatment and resource recycling of oil-containing sewage, it has always been a technical difficulty in environmental engineering. The traditional treatment methods mainly include gravity separation, chemical demulsification, membrane separation and biological treatment technologies, but all have limitations: gravity separation relies on the density difference between oil and water, and the treatment effect of emulsified oil is poor; chemical demulsification needs to add reagents, which is easy to cause secondary pollution; membrane separation technology has high cost and serious membrane pollution problem; biological treatment has long cycle and poor adaptability to high-concentration oil pollution.
