Abstract:

The electro-deionization membrane technology for treating highly concentrated inorganic wastewater containing ammonia nitrogen has been put forward the first time. The recent progress of reverse osmosis，electrodialysis and electro-deionization membrane technologies and their integration membrane technology for the recovery of ammonia nitrogen from inorganic wastewater are introduced，and the characteristics of various membrane technologies in the engineering application are analyzed. The wastewater system works under the condition of close-loop recycling，and at the same time，pure water and inorganic ammonia salt are recovered. It is energy saving and discharges less water， having excellent economic and environmental benefits.

Key words: electro-deionization, electrodialysis, reverse osmosis, integrating membrane, wastewater containingammonia nitrogen
