摘要
随着当今水资源危机日益突出,实现废水"零排放"是火电厂可持续发展的必经之路。文章分析了实现张家口电厂"零排放"所采取的主要节水技术,介绍了各系统废水处理方式及回用途径,重点介绍了以超滤反渗透为主体工艺的废水回收系统在火电厂节水中的首次应用,并评价了节水效果。
As the water shortage becomes crisis, the zero discharge of waste water is the necessity for sustained devel- opment of thermal power plant. This paper analyzed the major water saving technologies adopted by Zhangjiakou Power Plant in order to achieve the goal of zero discharge. It described the treatment methods of waste water for various systems as well as the recycling use methods, in particular the first application of uhrafiltration reverse osmosis system on the water saving of thermal power plant. The result was evaluated for water saving.
