摘要:

结合低碳氮比污水特点, 评述了以内源提供有机碳源实现反硝化, 以及利用自养菌脱氮的厌氧氨氧化和氢自养型反硝化等新型生物脱氮技术, 介绍了它们在低碳氮比废水处理中的反应机理、应用进展、优势以及需要解决的问题。该项研究为经济高效地处理低碳氮比污水提供了理论依据。

关键词: 低碳氮比, 脱氮, 废水处理

Abstract:

In view of the characteristics of sewage with low C/N, some new types of biological denitrification technologies, such as denitirification realized by supplying organic carbon sources from endogenesis, and denitrification-anammox, hydrogenotrophic type of denitrification being made of autotrophic bacterium are summarized. The reaction mechanism, application progress, advantages and problems to be solved of these technologies applied to the treatment of sewage with low C/N are introduced. The research provides theoretical evidence for the efficient and economic treatment of sewage with low C/N.

Key words: low C/N, denitrification, wastewater treatment
