Solution regeneration helps to save resources and protect the environment.Therefore,the princi-ple,structure,characteristics and research status of air regeneration,electrodialysis regeneration,mem-brane distillation regeneration and mechanical vapor compression regeneration among solution regeneration technologies are reviewed.The air regeneration technology can complete the high concentration solution regeneration,processing temperature is not high,can make full use of low-grade waste heat,but this meth-od of processing capacity is small,high energy consumption;electrodialysis regeneration technology can be used for two different salts of solution regeneration;membrane distillation regeneration technology can be low-grade heat or waste heat reuse;mechanical vapor compression regeneration technology can be comple-ted in a higher concentration of solution regeneration,processing capacity is large,compared with the tra-ditional compared with the traditional single-effect evaporation,the energy consumption is greatly re-duced.
