主流部分亚硝化-厌氧氨氧化工艺脱氮功能菌群的控制策略研究

部分亚硝化-厌氧氨氧化（partial nitrification-anammox，PN/A）工艺低耗高效，被视为最有可能替代传统硝化-反硝化并成为实现污水处理厂（WWTP）能源自给的主流脱氮技术。基于PN/A主流脱氮工艺现存部分亚硝化不稳定、功能菌种富集难的瓶颈与挑战，总结了PN/A反应器的应用现状，重点综述了氨氧化细菌、厌氧氨氧化细菌的持留、富集方法，分析了亚硝酸盐氧化细菌的有效抑制策略，并针对现状问题提出未来发展建议，为主流PN/A工艺实现工程化、规模化提供科学参考。

RESEARCH ON CONTROL STRATEGY OF NITROGEN REMOVAL FUNCTIONAL BACTERIA IN MAINSTREAM PARTIAL NITRIFICATION-ANAMMOX PROCESS

Partial nitrification-anammox(PN/A)process is considered to be a viable alternative to traditional nitrification-denitrification technology and become the mainstream nitrogen removal technology to achieve energy self-sufficiency in wastewater treatment plants(WTTPs), because of its low consumption and high efficiency. Based on the existing bottlenecks and challenges of mainstream PN/A process, such as partial nitrification instability and difficulties of enriching functional bacteria, the current application status of the PN/A reactor was summarized, the retention and enrichment methods of ammonia oxidizing bacteria (AOB) and anaerobic ammonia oxidizing bacteria (AnAOB) were reviewed in this article. Strategies for effective nitrite oxidizing bacteria (NOB) inhibition were also analyzed, while future development suggestions were put forward for the current problems, to provide scientific reference for the mainstream PN/A process to realize engineering and scale-up.
