In　this　study,　a　novel　integrated　anaerobic　ammonium　oxidization　with　partial　denitrification　process　(termed　as　ANAMMOX-PD)　was　developed　for　advanced　nitrogen　removal　from　high-strength　wastewater,　which　excess　NO3-N　produced　by　ANAMMOX　was　fed　into　PD　reactor　for　NO2-N　production　and　then　refluxing　to　ANAMMOX　reactor　for　further　removal.　Results　showed　that　total　nitrogen　(TN)　removal　efficiency　as　high　as　97.8%　was　achieved　and　effluent　TN-N　was　below　20　mg/L　at　influent　TN-N　of　820　mg/L.　Furthermore,　the　feasibility　of　simultaneously　treating　domestic　wastewater　was　demonstrated　in　ANAMMOX-PD　process,　and　NH4+　-N　removal　efficiency　of　96.7%　was　obtained.　The　nitrogen　removal　was　mainly　carried　out　through　ANAMMOX　pathway,　and　high-throughput　sequencing　revealed　that　Candidatus_　Brocadia　was　the　major　ANAMMOX　species.　The　presented　process　could　effectively　solve　the　problem　of　excess　nitrate　residual　in　ANAMMOX　effluent,　which　hold　a　great　potential　in　application　of　currently　ANAMMOX　treating　high-strength　wastewater　(e.g.　sludge　digestion　supernatant).　(C)　2016　Elsevier　Ltd.　All　rights　reserved.
