生物脱氮新技术探讨

Discussion on New Technology of Biological Nitrogen Removal

废水生物脱氨一直是水污染控制的一个重要研究方向。该文回顾了传统生物脱氮技术的基本原理,介绍了短程硝化反硝化、同时硝化反硝化两种生物脱氮的新技术,指出了一些有待研究的问题;并对这两种技术的结合提出了一些看法,指出了它的研究及应用前景。

Biological Nitrogen Removal of sewage is always an important aspect to be investigated. A review is given to traditional biological technology for Nitrogen removal at first, then it introduces two new technologies： Shortcut Nitrification Denitrification and Simultaneous Nitrification Denitrification, points out some problems that is waited to investigate; it also bring forward some opinions for the combining of the two technologies,points out its foreground of investigating and applying.
