Abstract:

Oily wastewater is difficult to be treated due to the high emulsion stability, and its efficient purification technology has become a research hotspot. Oil-water separation technology by electric demulsification has shown broad application prospects in the field of oil-water separation. In this paper, the principles, research progress, and practical applications of six types of electric demulsification technologies, including electroflotation, electroflocculation, electrophoresis, dielectrophoresis, electrochemical oxidation, and microelectrolysis were extensively discussed. The advantages and disadvantages of each technology were analyzed, and the future research focus and development direction of electric demulsification technology for oily wastewater were summarized. It was proposed that research should be strengthened in the micro mechanism of oil-water separation technology by electric demulsification, system adaptability, materials and equipment, energy consumption and efficiency balance, and the development of joint technologies.

Key words: oily wastewater, electric demulsification, electroflotation, electroflocculation, electrophoresis, dielectrophoresis, electrochemical oxidation, microelectrolysis
