好氧颗粒污泥处理高浓度氨氮废水的研究

Studying on Waste Water with High Concentration Ammonia-Nitrogen by Aerobic Granular Sludge

通过厌氧-好氧交替工艺培养好氧颗粒污泥,采用成熟好氧颗粒污泥处理高浓度氨氮废水,对不同pH、反应时间、进水浓度条件下好氧颗粒污泥微生物处理高浓度氨氮废水的效果进行了研究。实验结果表明,在进水氨氮浓度较高（460 mg/L）、pH为7~8、温度20℃左右的条件下,稳定运行15天,氨氮的去除率较高。

The paper gives some methods such as training aerobic granular sludge by anaerobic - aerobic interactive process, dealing with high concentration of ammonia nitrogen waste by mature aerobic granular sludge, etc. , to study the effects of dealing with waste water with high concentration Ammonia--Nitrogen in the different PH value, reaction time, concentration of water and the conditions of aerobic granular sludge microbial. The results show that a higher concentration of ammonia in water （460 mg / L）, PH between 7 to 8, the temperature around 20 under the conditions of stable operation of 15 days, the ammonia nitrogen removal rate is higher.
