| 中文摘要 |
| 从厌氧生物膜反应器、异养一好氧生物膜反应器和硝化生物膜反应器三方面,全面考察了进水底物浓度(So)对生物膜反应器稳态出水水质(Se)的影响,发现Se随So的变化呈现半U形曲线。在传统的线性模型基础上,提出了非线性Se-So的模型,该模型能很好地定量描述试验所得数据,并从文献中的数据得到了进一步的验证。所提出的临界进水底物浓度的概念在实际生物膜反应器设计及运行中,具有重要应用意义。 |
| 英文摘要 |
| This paper mainly investigated the effect of influent substrate concentration(So)on steady state effluent quality(Se) for anaerobic, heterotrophicaerobic and nitrifying biofilm reactors.It was found that variation pattern of So as Se changes is subject to a semi-U shaped curve.Based on the known linear model,a nonlinear So-Se,model was developed.It was demonstrated that this model can provide a quantitative description for experimental data,also was confirmed by the data from literature.The proposed concept of critical influent substrate concentration has great importance in future design and operation of biofilm reactor. |
