摘要：

介绍了烟台发电厂投入运行的循环冷却排污水的深度处理系统，该系统由预处理、预除盐、一级除盐、深度除盐等部分组成，它以电厂的循环排污水作为水源制取除盐水，与原有的水处理车间的除盐水一起供应烟台市供热管网首站用水和电厂锅炉用水。系统投入运行后降低了循环水的浓缩倍数，改善了循环水的运行工况，解决了电厂中循环水排污水处理难的问题，实现了循环冷却排污水的回收利用，达到了循环水的零排放，提高了水利用率，降低了电厂的水耗。

Abstract:

The system of advanced treatment the circulating cooling discharged water in Yantai Power Plant is introduced. The system which consists of pretreatment, predemineralization, primary demineralization and deep demineralization, makes the circulating cooling discharged water in Yantai Power Plant as aquifer, to yield desalted water. The water, combined with the desalted water which is yielded by water treatment workshop, is supplied to the boiler and primary heat exchanger of heat supply network in Yantai. Since the system has been put into operation, it has diminished the cycles of concentration of circulating water, improved the operational condition of circulating water, solved the problems of circulating water treatment, realized the circulating cooling discharged water recycling, fulfilled the zero discharge of circulating water, enhanced the utilization coefficient of water resources and reduced the water consumption in Yantai Power Plant.

Key words: power plant, circulating water, drainage, reuse
