摘要：
The forward osmosis-membrane distillation (FO-MD) coupling process, as a new type of membrane separation process technology, has the characteristics of simple process equipment, high treatment efficiency, and no secondary pollution. The coupling process includes two membrane processes with high rejection rates. It can realize double barrier treatment of wastewater, thereby improving the removal efficiency of organic pollutants, oily substances, surfactants and other pollutants, and has a good application prospect in the treatment of difficult wastewater. In this paper, the working principle and process characteristics of the FO-MD coupling technology were comprehensively analyzes. The future research directions of the process were pointed out that is to improve the processing efficiency and save the processing cost through the development of high-performance membrane materials and the optimization of the processing process. The latest application of FO-MD coupling process in the treatment of high concentration organic wastewater, high concentration ammonia nitrogen wastewater and oil and high salt wastewater were introduced, and the problems to be solved in FO-MD coupling process were discussed. Several future development directions of FO-MD coupling process were summarized, which can provide reference for the further development of this technology. © 2021, Chemical Industry Press Co., Ltd.
