| Abstract: | The research trend of FA inhibitions on nitrifies were introduced,including the inhibition mechanism and inhibition mathematic model of ammonia-oxidizing bacteria and nitrite-oxidizing bacteria,as well as the strategy to reduce or avoid inhibition effects.In addition,the selective inhibition effects of FA on the start-up and stability of partial nitrification were illuminated.In particular,the combinative effects of FA inhibition and other factors(such as dissolved oxygen and temperature) on short-cut nitrification were presented in the review. |

| Keywords: | high strength ammonia short-cut nitrification free ammonia biological nitrogen removal stability |
