同时硝化反硝化(SND)脱氮技术研究

Study on the Technology of Nitrogen Removal by Simultaneous Nitrification and Denitrification(SND)

指出了同时硝化和反硝化工艺与传统的生物脱氮工艺相比,可以节约氧和碳源的耗量,大大降低设备运行费用,具有很大的发展前途。结合近年来国内外脱氮的最新研究成果,从优点、机理、影响因素等方面对同步硝化反硝化进行了探讨。

Comparing with traditional process of biological nitrogen removal, simultaneous nitrification and denitrification（SND） can save the consumption of oxygen and organic carbon, and greatly reduce the cost of equipment operation, thus it has great development potential. In this paper, according to the latest research results on nitrogen removal at home and abroad, it analyses the simultaneous nitrification and denitrification（SND） from the perspectives of advantages, mechanism and the affecting factors of SND.
