摘要：
With the rapid development of China's economy and the continuous advancement of modernization and industrialization, environmental protection and sustainable development have become the necessary conditions for resource development and industrial production. In the process of resource development and industrial production, a large amount of heavy metal wastewater and organic wastewater will be produced. Electrodialysis technology has low energy consumption, low sensitivity to water quality, simple operation, and excellent concentration and separation performance, so it is widely used in the separation and extraction of metals and organics in industrial wastewater. This paper summarized the basic principle and research progress of metal and organic recovery in industrial wastewater, introduced the recovery cases of various metals in different systems and organic recovery cases, analyzed the influence and mechanism of different process parameters such as pH, operating voltage and current, solution flow and ion concentration on the electrodialysis effect, and looked forward to the development direction of electrodialysis technology for separation and extraction of metal and organic matter. It provides a theoretical basis for electrodialysis technology to treat heavy metal wastewater and organic wastewater, and realize the separation and extraction of heavy metal and organic matter. © 2023 Chemical Industry Press.
