膜技术处理高盐废水的研究进展

Research Progress of High-salt Wastewater Treatment by Membrane Technology

高盐废水具有含盐量高,有机物浓度高,难降解的特点。膜技术因其无副产物产生、控制简单、设备成熟被广泛应用于高盐废水处理中。介绍了正渗透、反渗透、膜蒸馏、渗透汽化膜技术及膜工艺组合技术处理高盐废水研究进展,对比了不同膜技术的技术特点,为未来高盐废水处理提供参考。

High salt wastewater has the characteristics of high salt content,high concentration of organic matter and difficult degradation.Membrane technology is widely used in the treatment of high-salt wastewater because of its no by-product production,simple control and mature equipment.In this paper,the research progress of forward osmosis,reverse osmosis,membrane distillation,pervaporation membrane technology and membrane process combination technology to treat high-salt wastewater was introduced,the technical characteristics of the different membrane techniques were compared,providing some reference for high-salt wastewater treatment in the future.
