Abstract：

The　primary　challenge　of　applying　partial　denitrification/anammox　(PD/A)　to　municipal　wastewater　treatment　lied　in　the　enrichment　of　functional　bacteria　with　a　considerable　autotrophic　nitrogen　removal　performance.　The　results　showed　influent　NO3−-N:　NH4+-N,　reaction　time　and　temperature　would　influence　anammox　nitrogen　removal　contribution.　15N　isotopic　tracing　technology　further　revealed　the　average　anammox　contribution　rate　was　up　to　94.8　%.　Extending　reaction　time　was　an　effective　measure　to　improve　simultaneously　PD　and　anammox　activity.　Microbial　community　indicated　partial　denitrifying　bacteria　(Bacillus)　and　anammox　bacteria　(Candidatus　Brocadia)　were　enriched　with　abundance　of　27.27　%　and　7.09　%　at　NO3−-N:　NH4+-N　of　1:1.　The　correlation　analysis　showed　that　NO3−-N:　NH4+-N　ratio　played　the　positive　role　for　Bacillus　enrichment,　and　low　temperature　was　favorable　to　the　enrichment　of　Thauera　and　Candidatus　Jettenia.　Overall,　this　study　demonstrated　the　reasonable　operational　strategy　would　strengthen　anammox　contribution　and　facilitate　enrichment　of　functional　bacteria.　©　2024
