摘要/Abstract

摘要：

脱氮是大部分废水处理系统中不可缺少的一环。与物理化学法相比，生物脱氮具有经济有效、操作方便以及无二次污染的优势。综述了各类生物脱氮技术的研究背景、机理及其存在的问题，并作了简单比较。结果表明，全程硝化反硝化应用广泛且稳定可靠。异养硝化-好氧反硝化对碳源需求较高（COD/N>10），而短程硝化反硝化可节约大量能源和碳源。厌氧氨氧化脱氮速率高且无外加碳源，但细菌富集和前期启动较为困难。

关键词: 脱氮, 自养硝化, 好氧反硝化, 厌氧氨氧化

Abstract:

Nitrogen removal is an indispensable aspect of most wastewater treatment systems. Compared with physical and chemical methods, biological nitrogen removal is economically effective, easy to operate, and free from secondary pollution. The research background, mechanisms and deficiency of various nitrogen removal technologies are summarized, and compared briefly. The results show that complete nitrification and denitrification are widely used, and are stable and reliable. Heterotrophic nitrification-aerobic denitrification has higher demand for carbon sources (COD/N>10), while short-cut nitrification-denitrification can save lots of energy and carbon sources. The anaerobic ammonium oxidation(anammox) denitrification rate is high, and does not have exotic carbon source. However, the bacteria enrichment and prophase start-up are difficult.

Key words: nitrogen removal, autotrophic nitrification, aerobic denitrificaiton, anammox
