摘　　要：低温条件下生物脱氮处理会受到大幅抑制乃至停止,如何保证生物脱氮处理在低温下高效稳定运行是研究热点。通过对低温条件下污水生物脱氮的最新进展进行综述,介绍了不同生物强化手段与脱氮工艺调控手段对于低温污水生物脱氮效果的改善,阐述了目前研究中遇到的问题并展望该方向发展前景。Biological nitrogen removal is significantly inhibited even interrupted under low temperature condition, so how to ensure efficient and stable operation of the biological nitrogen removal process is a research hot spot. The research progress in biological nitrogen removal from wastewater under low temperature condition was reviewed, and the improvement effects of different bioaugmentation and process control means were summarized. Existing problems and development prospect of current research were expounded.
