【Abstract】 The advances in researches on oil/water separation membranes as a class of developing techniques of oily wastewater treatment are reviewed. Following topics are covered. Introductory part: membrane separation methods, advantages and classification. Some funcdamental mechanisms: oil/water separation, phase separation, and mass transfer. Membranes for oil/water separation: characteristics, hydrophobic and hydrophilic organic polymer membranes, ceramic and inorganic oxide membranes, surface hydrophilization modification of organic membranes. Main factors influencing membrane separation: working pressure and time, oil content in wastewater, membrane thickness, temperature, flow rate at surface, membrane manufacturing technology, existance of electrolyte(s) and surfactant(s), surface coarseness.更多还原
