摘要:

好氧颗粒污泥(AGS)因具有独特的空间结构,可延径向形成氧传质梯度,为不同功能菌的分区定殖提供了必要场所,因而可实现单级脱氮。AGS内主要脱氮途径有同步硝化反硝化(SND)、厌氧氨氧化(Anammox)、异养反硝化、菌藻耦合脱氮等。综述了AGS各种途径的脱氮效果,总结了各途径的优缺点及适用范围,分析了现有研究存在的问题,并提出了相应的建议。

Abstract:

The unique spatial structure of aerobic granular sludge(AGS) can form a radial oxygen mass transfer gradient, which provides necessary habitats for colonization of different functional bacteria, thus achieving single-stage denitrification. The main denitrification pathways in AGS include simultaneous nitrification and denitrification, anammox, heterotrophic denitrification, and coupling denitrification of algae and bacteria. The denitrification efficiency of AGS by different pathways were reviewed, and their advantages, disadvantages and application scope were summarized. The problems existing in existing studies were analyzed, and corresponding suggestions were proposed.

Key words: aerobic granular sludge, simultaneous nitrification and denitrification, anammox, heterotrophic denitrification, coupling denitrification of algae and bacteria
