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.
实验研究结果表明:本工艺中,短程硝化反应的最佳pH值在8.0~8.5之间,当pH小于6时,整个硝化反应都会受到抑制,当pH在6~7之间时,随着游离氨浓度的降低,在曝气后期,硝化菌将会占据优势;FA浓度对短程硝化反应的影响是通过对亚硝酸菌和硝酸菌的抑制来实现的,在本研究条件下,游离氨对亚硝酸菌的抑制浓度在10mg/L以上,对硝酸菌的抑制浓度在1.0mg/L以下;温度对短程硝化反应的影响是双重的,既影响微生物的生理活性,又影响FA浓度。
