| Abstract: | 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. |
