Progress in Research and Application of Circulating Cooling Water Treatment Technologies in Power Plants

Abstract 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.
