摘要
简述了国内外近几年氨氮脱除的生物技术研究进展情况。近年来出现了短程硝化反硝化、同时硝化反硝化和厌氧氨氧化等生物脱氮的新概念和新技术,为生物脱氮技术开拓了新的发展空间;同时特殊菌株的筛选和培育也是氨氮脱除生物技术发展的热点之一。最近的研究结果表明存在着单细胞细菌好氧代谢过程氨氧化耦合脱除氨氮的可能性与可行性。
There appear many novel technologies and new concepts such as shortcut nitrification denitrification?simultaneous nitrification denitrification and anaerobic ammonium oxidation, which develop the field of biotechnology of ammonia removal in wastewater. Simultaneously the selection and incubation of especial bacteria is also the hotspot of biotechnology of ammonia removal. Recently researches indicated that it was possible to couple aerobic metabolism and ammonia oxidation in single bacteria.
