- A good correlation of ammonia removal efficiency, nitrification rate and TN removal efficiency was found. 氨氮去除率和硝化速率、总氮去除率具有较好的相关性。
- The nitrification rate is obviously increased as the temperature increases from 13 to 20In dissolved oxygen (DO) single factor experiment, the biofilter operates under three DO levels of 0.3mg/L, Img/L and 2mg/L, and ascertain the optimum DO is 1.0mg/L. 随着温度从13℃左右升高到20℃后，活性污泥段的硝化能力明显提高。 在滤池段工况中，首先分别考察了DO为0.;3mg/L(不曝气)、1mg/L及2mg/L三个工况下滤池段的运行性能，确定DO=1
