The application of ozone (O₃) in wastewater treatment is critically limited by O₃ mass transfer and oxidation capacity. An electro-catalytic membrane contactor was designed to improve O₃ performance in these two aspects simultaneously. Electro-catalytic membrane contact ozonation (ECMCO) has a higher removal rate for nitrobenzene than that of the single membrane contact ozonation and electrolysis process due to the high oxidation potential of hydroxyl free radicals (•OH). O₂ mass transfer was promoted through the configuration of the composite membrane; O₃ mass transfer was dominated by the liquid boundary layer. ECMCO produced more •OH than that from other methods, and most of the •OH quenched itself instead of reacting with organic compounds due to the poor mass transfer between the electro-catalytic layer and bulk liquid. The oxidation capacity of the ECMCO process was limited, but a composite membrane with high porosity and thin electro-catalytic layer may significantly mitigate these limits.

臭氧（O ₃）在废水处理中的应用受到O ₃传质和氧化能力的严格限制。设计了一种电催化膜接触器，以同时提高这两个方面的O ₃性能。由于羟基自由基（•OH）的高氧化电位，电催化膜接触臭氧化（ECMCO）对硝基苯的去除率高于单膜接触臭氧化和电解过程。通过复合膜的构型促进了O _2的传质。Ø ₃传质主要由液体边界层决定。ECMCO产生的•OH比其他方法产生的更多•OH，由于电催化层与本体液体之间的传质不佳，大多数•OH会自行淬灭而不与有机化合物反应。ECMCO工艺的氧化能力受到限制，但是具有高孔隙率和薄电催化层的复合膜可能会大大减轻这些限制。
