摘要
本文详细介绍了北京京丰天然气燃机联合循环电厂使用超滤-反渗透膜组合工艺处理循环水排污水。循环水排污水回用系统的最大问题是反渗透膜的污染控制问题。因为循环水排污水相对水质较差,因此对预处理技术要求较高,采用超滤膜作为预处理系统,能够很好地解决这个问题。北京京丰热电厂通过长时间的工业化运行,证明了在处理回用循环水排污水过程中,超滤作为反渗透预处理系统的可行性,也积累了该工艺处理循环水排污水用于电厂循环补充水和锅炉补给水方面的应用经验。
The technological process of dual-membrane (UF an RO system) process for treatment of sewage from power plant is introduced in this paper. The long-term operation of the technological process in Beijing Jingfeng Thermal Power Plant proved ultrafiltration (UF) as the pretreatment of reverse osmosis (RO) to be feasible, and also accumulated applicable experience in treatment of sewage from power plant by the dual-membrane process, having an important significance for water saving in power trade.
