Progress of Research on the Application of Electrodialysis Technology in Treatment of Saline Industrial Wastewater
In order to address the problem of high salt pollution in industrial wastewater containing salt,electrodialysis technology has always been a research focus for desalination of industrial wastewater containing salt due to its unique advantages.Three new types of electrodialysis processes,such as electrodeionization,electrodialysis reversal and electrodialysis of bipolar membranes were introduced.Something was elaborated on the application progress of electrodialysis technology in rare earth industrial wastewater,coal chemical wastewater,lithium extraction and processing,and lithium battery recovery in recent years.At present,electrodialysis technology still has shortcomings in terms of desalination cost and desalination performance.Therefore,electrodialysis technology needs to be coupled with other processes,optimize the system structure and process parameters of electrodialysis technology,and optimize ion exchange membranes as key research directions.
