摘要生物强化技术广泛应用于废水生物处理中,而竞争力和适应性强的高效菌株筛选是生物强化技术的决定性
因素。论述了利用具有代谢性能的可移动基因片段强化、基因工程菌强化和常规微生物学手段分离2 菌株的生物强化技术,
并阐述了生物强化技术在废水生物处理过程中去除难降解有机3物,去除过量的2氮、磷等营养物质,维持生物系统稳定性中
的应用。
关键词高效菌筛选基因工程可移动基因组分废水生物处理

Abstract B ioaugmentation technology has been widely used in biological wastewater treatment in recent
years. The screen of high efficient bacteria with stronger adap tability petition in new environment is one of
decisive factors for bioaugmentation technology. The paper elaborates three methods for augmentation of catabolic
mobile ic elements, gene engineering strains and bacteria which were isolated by conventionally m icrobiolog
