摘要
采用曝气生物滤池(BAF)对受污染水源水进行了除氨氮效果研究,结果表明,当原水氨氮质量浓度在0.240～1.407 mg/L范围内时,氨氮平均去除率为83%,进水氨氮的质量浓度人工增加至0.717～12.455 mg/L时,氨氮平均去除率为88%,具有较好的氨氮去除效率和抗冲击负荷能力;同时探讨了进水氨氮容积负荷对氨氮去除效果的影响。
The ammonia nitrogen in polluted raw water was treated by biological aerated filter （BAF）. The results showed that when the concentration of ammonia nitrogen in the range of 0.240- 1.407 mg/L, the average removal rate of ammonia nitrogen was 83 %, while the concentration increased to 0.717- 12.455 mg/L by manmade, the average removal rate of ammonia nitrogen was 88 %, which had better efficiency of ammonia nitrogen removal rate and resistance to impact load. Meanwhile, the ammonia nitrogen volumetric loading of inlet water to ammonia nitrogen removal efficiency was also discussed.
