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.
