Research Progress of High-salt Wastewater Treatment by Membrane Technology
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.
