The oil substances contained in the oily wastewater include natural petroleum, petroleum products, tar and fractions thereof, and edible animal and vegetable oils and fats. The pollution to water is mainly petroleum and tar. Because the oil concentration in the waste water discharged by different industrial departments is greatly different, for example, the oil content of the waste water generated in the oil refining process is about 150-1000 mg/L, the tar content in the coking waste water is about 500-800 mg/L, and the tar content in the waste water discharged by a gas generation station can reach 2000-3000 mg/L. At present, oily wastewater treatment firstly needs to be carried out by standing to separate oil from water, and then floating and heavy oil are recovered by an oil scraping mode, but the treatment mode comprises the following steps:
1. because the existing oily wastewater enables oil and water to be automatically separated through standing, the treatment mode not only consumes a large amount of time and has low efficiency, but also has small effect on the wastewater with low oil content, and a part of oil in the wastewater is emulsified, so that the oil and water cannot be automatically separated through standing at all;
