Experimental results showed that, in this process, the optimal pH of the shortcut nitrification was 8.0～8.5; when the pH was less than 6,the nitrification is completely inhibited; when the pH was 6～7, at the end of aeration, the Nitrobacteria become the dominant bacteria because of the dropping of the free ammonia concentration. It is known to all, the activity of the Nitrobacteria and Nitrosomonas was affected by FA concentration, so nitrification was affected by FA concentration. According to the author's research results, the FA concentration which inhibit the Nitrobacteria was below 1.0mg/L,which inhibit the Nitrosomonas was above 10mg/L.
