城市中水在电厂循环冷却水系统的应用与展望

中水回用对于解决水资源短缺具有其他方法无法比拟的优势，其成功应用将产生巨大的经济效益和社会效益。而城市中水经深度处理后回用于电厂循环冷却水补充水系统，不仅可以解决电厂用水紧缺的状况，而且可减轻污水排放对环境的不利影响。文章阐述了城市中水回用的发展现状，从火电厂循环冷却水系统的对补水的水质要求出发，结合电厂循环冷却水以及城市中水的水质特点，选择相应的中水处理工艺方案。此外就中水回用中存在的问题进行分析，并对其发展前景进行预测。

Application and Prospect of Municipal Reclaimed Water in Circulating Cooling Water System of Power Plant

Reclaimed water reuse has a special predominance to any other methods on solving the shortage of water resources. There will be obvious economic and social benefits if reclaimed water is applied successfully. Municipal wastewater is treated and then reused as make - up water of circulating cooling water system in Power Plant, which not only solves the severe scarcity of water resource but also alleviates the pollution of wastewater disposal to environment. This paper provides an overview about reuse of municipal reclaimed water. On the basis of different demand of water quality of circulating cooling water system in power plant, at the same time, the characteristics of circulating cooling water and reclaimed water are also considered; corresponding treatment processing and technology of reclaimed water were chosen. In addition, the existing problem of wastewater reuse was be analyzed and its promising future was be discussed in this research.
