| مستخلص: | The ammonia-oxidizing bacteria were immobilized by copolymer with cell proliferation technology. The effects of NH(4+) -N load, HRT, free ammonia (FA) and organic matter on short-cut nitrification process were studied. The results showed that when influent NH(4+) -N load were 100 mg/L, 150 mg/L and 200 mg/L respectively, effluent NH(4+) -N concentration was less than 10 mg/L. When the system run for 3 h, 6 h and 12 h, corresponding to influent NH(4+) -N concentration of 25.8 mg/L, 51.1 mg/L and 93.3 mg/L respectively, NH(4+) -N concentration was low in effluent with high short-cut nitrification efficiency. The HRT could be adjusted to optimize the system operation with variation of influent NH(4+) -N concentration. The results also indicated that the ammonia-oxidizing bacteria were restrained while free ammonia concentration was over 9 mg/L. The activity of the ammonia-oxidizing bacteria could be enhanced under existence of low-molecular-weight organic compounds, but the short-cut nitrification efficiency was little affected. In addition, the short-cut nitrification and denitrification could be realized with existence of organic compounds during the experiment. |
