摘　　要：对电力行业循环冷却系统排污水现有的深度处理及回用技术进行了介绍和分析。结合北京京西燃气热电有限公司循环冷却排污水深度处理示范工程,针对电厂循环水排污水高盐、高氮低碳的水质特点,采用复合生物滤池+活性砂滤池工艺进行处理,对处理系统的功能设计、结构、性能和试验等进行了详细介绍,提出将循环排污水处理工艺一体化自动控制技术用于电力行业循环系统排污水污染减排工艺,实现了废水达标排放。This article makes an introduction and an analysis of the advanced treatment and reuse technology of circulating cooling sewage water of the power industry. Combined with the engineering example of wastewater treatment demonstration project of Beijing Jingxi Gas-fired Thermal Power Co.,Ltd., to the water characteristics of the power plant＇s wastewater with high N/C and high salt, the treatment process of CBF＋ active sand filter is adopted. The functional design, structure, properties and experiment are introduced in details. A new treatment process for circulating cooling sewage water of the power industry is proposed to guarantee effluent to be up to the discharge standard, through which waste water can be realized to be discharged up to the standard.
