| Abstract: | Reverse osmosis membrane technology is the leading treatment technology for brine wastewater from coal chemical industry. However, its recovery rate is usually only 75 percent. The treatment of the concentrated water from the process is significant for the sustainable development of coal chemical industry and environmental protection. Investigate the desalination-concentration of reverse osmosis drained wastewater from concentration technologies, membrane materials and polyvinylidene fluoride （PVDF） membrane preparation. Introduce its research progress and the membrane materials used in the process. Analyse the influencing factors of PVDF membrane. |
