摘要：
Oily wastewater is generated in many industrial processes, such as petroleum refining, petrochemicals, food, leather and metal processing, and has always been the focus of industrial pollution control. With the continuous development of industrial production technology, the types of characteristic pollutants in oil-containing wastewater and their discharges have also continued to increase, posing challenges to the deep removal and recovery of oil from industrial wastewater. Due to the variety of organic matters in the oily wastewater, the different environments, and the complex internal reactions, it not only affects the production efficiency of the multi-stage process, but also has an environmental risk. Therefore, the efficient and advanced treatment and utilization of industrial oily wastewater is an inevitable requirement for industrial pollution control, and has an important role in promoting the sustainable development of industrial production. In view of this, on the basis of systematic analysis of the characteristics of industrial oily wastewater, this article reviews the latest research progress at home and abroad on the treatment of emulsified oil and dissolved oil from the perspective of separate processes and combined processes, and focuses on principle and characteristics, degreasing potential, application benefits and its advantages compared with the other degreasing technologies. Finally, the perspective for resin degreasing technologies is presented. © 2021, Chemical Industry Press Co., Ltd. All right reserved.
