摘　　要：综述了陶瓷膜改性方法,以及在含油废水中的应用,然后对改性陶瓷膜处理含油废水的性能进行了讨论和比较。发现除了传统的溶胶-凝胶法和浸镀方法外,原子层堆积(ALD)在控制层厚和孔径调整方面具有良好的应用前景。纳米级的金属氧化物,如二氧化钛、ZrO_(2)、Fe_(2)O_(3)以及氧化石墨烯被认为是含油废水处理中陶瓷膜改性的潜在候选材料。而带电陶瓷膜在污垢控制、拒油和增加水通量方面有一定潜力,但也有其局限性。The modification of ceramic membrane and its application in oil-containing wastewater are reviewed firstly,and then the performance of the modified ceramic membrane in the treatment of oil-containing wastewater is discussed and compared.In addition to the traditional sol-gel method and dip plating method,atomic layer stacking(ALD)has a good application prospect in controlling layer thickness and pore size adjustment.Nanoscale metal oxides such as titanium dioxide,ZrO_(2),Fe_(2)O_(3)and GO are considered as potential candidates for ceramic membrane modification in oily wastewater treatment.However,charged ceramic membranes have some potential in dirt control,oil exclusion and increased water flux,but they also have their limitations.
