In　the　study,　the　salt-tolerant　partial　denitrification　and　Anammox　(ST-PDA)　process　was　established,　meanwhile,　the　feasibility　of　salinity　inhibition　model　as　the　boundary　control　method　and　the　subsequent　operation　performance　were　studied.　Study　indicated　that　the　performance　of　salt-tolerant　PD　sludge　was　the　optimum　under　the　10　g.L-1　salinity,　and　AnAOB　also　maintained　high　activity　at　the　salinity.　Haldane　and　Aiba　models　verified　that　NO3--N　(substrate)　and　FNA　(product)　would　have　negative　consequences　for　performance　of　ST-PDA　system.　However,　the　effect　of　FNA　would　be　eliminated　by　self-alkalization　in　the　denitrification　process.　A　90%　nitrogen　removal　rate　was　achieved　and　the　average　effluent　total　nitrogen　of　17.8　mg.L-1　was　maintained　in　the　system.　The　high　throughput　sequencing　revealed　that　the　species　richness　decreased　with　the　salinity　increased,　while　Thauera　played　a　major　role　in　nitrogen　removal　in　saline　environment.　The　study　provides　a　novel　insights　for　salt-containing　industrial　wastewater.
