同步硝化与反硝化研究进展

The Progress of the Researches on the Simultaneous Nitrification and Denitrification(SND)

同步硝化与反硝化工艺同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。结合国内外研究,主要从生物学、生物化学和微环境理论的角度对这一技术进行了综述,对一些同步硝化反硝化新工艺进行了介绍。

In comparison with the traditional method for biological denitrification, the simultaneous nitrification and denitrification（SND）can reduce the consumptions of the oxygen and organic carbon,and thus decrease the operating cost of equipment, therefore it has a great developing prospect. Connecting with the domestic and foreign researches, this paper mainly sums up this technique from the angles of the biology, the bio-chemistry and the microenvironment theory, and introduces several new techniques of SND.
