摘要
火力发电厂用水量的约70%为对水质要求不高的循环冷却水,城市中水经过简单的处理即可作为循环冷却水使用。介绍了目前中水作为循环冷却水的技术现状及几种成熟的电厂中水回用处理工艺,探讨其存在的问题以及中水作为循环冷却水与其他传统的冷却方式的经济性比较。
Given that circulating cooling water, while taking up 70 percent of the total water use in thermal power plants, is not required to be of high quality, the reclaimed water from the city can serve as cooling water after some simple treatments. Therefore, this paper introduces the present technical conditions in using the reclaimed water as cooling water and presents several mature reclaimed water treatment processes in power plants. The existing technical problems in reclaimed water use are discussed and the methods of the reclaimed water used as cooling water with other traditional cooling systems are compared from a perspective of cost and effectiveness.
