| Abstract: | The recovery of resource and energy in sewage and wastewater is an important part of building a low-carbon society. Electro-driven membrane separation is an effective way to realize the resource utilization of sewage and wastewater, which combines electrochemistry with membrane separation technology, and enhances membrane separation effect by adjusting electric field or electrode potential. And it is expected to break through the technical bottlenecks of membrane fouling, weak selective separation and trade-off effect. The concept of electro-driven membrane separation was proposed for the first time, and the electro-driven membrane separation was divided into electrical control membrane separation, electrodialysis and membrane capacitance deionization. This paper focused on the recovery of valuable substances in wastewater via selective membrane separation, so as to realize the recycling of wastewater. Firstly, the basic research progress of electro-driven membrane separation technology was introduced. Then, the research progress of electro-controlled membrane separation, electrodialysis and membrane capacitor deionization was reviewed and summarized from the perspectives of membrane/electrode material innovation and process optimization. Finally, the future development direction of the technology was prospected from three aspects:basic research, material innovation and reactor development. |
