脱硫高盐废水零排放的电渗析工艺研究

Research on the Electrode Electro-Osmosis Process of Zero Discharge of Desulfurization and High Salinity Wastewater

目前,由于水资源的短缺和污染,电厂废水零排放已引起世界各国的高度重视。本文综述了我国脱硫废水在预处理、浓缩和固化过程中的处理情况,并展望了我国废水零排放的发展趋势,总结了不同零排放技术的性能及特点,其中膜基技术是废水零排放系统回收的有效手段。因此,本文重点研究了双极膜电渗析在脱硫高盐废水处理中的应用,讨论了其局限性和解决方案。

Due to the shortage and pollution of water, the zero discharge of waste water from power plants has attracted the attention in the world. In this paper, it was fi rstly summarized the treatment of desulfurized wastewater in the process of pretreatment, concentration and solidifi cation in China, then prospected the development trend of zero discharge of wastewater in China, and in the end concluded the performance and characteristics of different zero discharge technologies, among which the membrane technology is an effective method for zero discharge system recovery of wastewater. Therefore, this paper focuses on the application of bipolar membrane electrodialysis in the treatment of desulfurization and high-salt wastewater, and discusses its limitations and solutions.
