Anaerobic　ammonia　oxidation　(anammox)　has　shown　great　promise　for　nitrogen　removal　in　low　C/N　wastewater　such　as　landfill　leachate.　However,　11%　of　NO3--N　is　stoichiometrically　produced,　which　decreases　the　total　nitrogen　(TN)　removal　efficiency.　In　this　study,　a　strategy　for　post　anammox　was　developed　to　effectively　remove　TN　from　leachate.　A　tandem　conversion　of　NO3--N　to　NO2--N　(partial　denitrification)　was　accomplished　by　supplying　substrate　for　subsequent　anammox,　by　supplementing　the　electron　donor　deficient　condition.　This　process　greatly　improved　NH4+-N　and　TN　removal　from　leachate,　reaching　a　95%　efficiency.　Quantitative　real-time　polymerase　chain　reaction　results　showed　that　a　high　abundance　of　anammox　bacteria,　with　a　titer　of　10(9)　copy　numbers/L,　was　enriched,　accounting　for　9.66%　of　the　total　bacterial　community,　and　indicating　the　success　of　this　novel　strategy　for　the　TN　removal　in　leachate.　(C)　2018　Elsevier　B.V.　All　rights　reserved.
