In　order　to　find　out　the　removal　efficiency　of　nutrient　pollution　of　real　saline　sewage　and　the　influence　of　salinity　shock,　a　lab-scale　nutrient　removal　activated　sludge　system,　based　on　the　MUCT　configuration,　is　modified　to　treat　10　g/L　saline　sewage.　The　results　indicate　that　after　domestication　of　microorganism　at　10　g/L　salinity,　the　total　organic　nitrogen　and　phosphorus　average　removal　efficiency　can　achieve　87%　and　72%　respectively.　The　nutrient　removal　efficiency　was　also　changed　under　different　salinity　shock.　The　salinity　shock,　especially　increased　salinity　shock,　influences　phosphorus　removal　efficiency　much　more　than　the　removal　efficiency　of　nitrogen　and　organic　matter.
