If this kind of wastewater is directly discharged without effective treatment, it will cause serious pollution to the aquatic ecosystem, affect the survival of aquatic organisms, and possibly endanger human health through the food chain; at the same time, the discharge of oily wastewater does not meet the increasingly stringent environmental protection regulations. Therefore, it is an urgent need for environmental protection and sustainable development of industry to efficiently purify oily wastewater, remove oil substances therein, and ensure that wastewater discharge or reuse meets relevant standards.

[0003] In the existing oily wastewater purification technology, ethanol dilution method has been tried to be used for treating oily wastewater, and its basic principle is to utilize the solubility of ethanol to part of oil substances, to dilute the oil-water mixture in the upper layer of wastewater to a certain extent by mixing ethanol with wastewater. However, this method has significant limitations. Since the mixing of ethanol and oil substances mainly depends on physical stirring and molecular diffusion, for floating oil or dispersed oil in wastewater, the dilution effect of ethanol may be more obvious; but for oil substances in the deep layer of wastewater, especially emulsified oil and dissolved oil, ethanol is difficult to fully penetrate and mix with them, resulting in that the oil-water below cannot be effectively diluted and treated. In addition, the volatility and flammability of ethanol also increase the safety risk in the treatment process, and the addition of ethanol increases the treatment cost, which does not comply with the principles of resource conservation and environmental protection.
