英文摘要：

The existing concentration technologies including evaporation pond, multi-effect distillation, mechanical vapor recompression, electrodialysis（ED） and membrane distillation were introduced in the aspects of principles, advantages, disadvantages and the progress of research application.Furthermore, a novel effective brine concentration process based on electricity drive ion exchange membrane was proposed, and an application case was also evaluated. It was believed that the electricity drive ion exchange membrane process has notable advantages in capital cost, energy consumption and operating cost compared with existing technologies, which has broad prospects in future application.
