摘　　要：电厂循环冷却系统作为最有节水潜力的部门,其循环冷却水的处理是实现电厂节水减排的关键。基于此,从提高循环浓缩倍率和排污水回用两方面综述电厂循环冷却水研究进展,对提高循环冷却水浓缩倍率方法和其排污水的脱盐技术进行归纳,分析了现有技术的优缺点、应用现状和相关实验研究进展。并对技术发展方向进行了展望:研发抗污染、通量大的膜材料,更高效的预处理过程,绿色高效的电化学技术以及不同技术的组合优化将是电厂循环冷却排污水处理的研究方向。The power plant circulating cooling system is the most potentially water-saving department. The treatment of circulating cooling water is the key to realizing water saving and emission reduction in power plants. Therefore, the research progress of circulating cooling water in power plants is reviewed in this paper from the two aspects of increasing concentration ratio and sewage reuse. The method for increasing the concentration ratio of circulating cooling water and the desalination technology of its sewage are summarized. The advantages and disadvantages, application status and experimental research progress of the existing related technologies are analyzed. The future direction of technology development is also forecasted. It is concluded that the development of anti-pollution, high-flux membrane materials, more efficient pretreatment process, green and efficient electrochemical technology, and optimized combination of different technologies will become the research direction of power plant circulating cooling sewage treatment.
