| 摘 要： | 根据微生物生长动力学特征以及膜分离特征,建立恒通量下运行的一体式膜生物反应器系统出水COD数学模型,提出膜生物反应器处理效率的数学模型。以实验及模型为基础,分别对进水COD浓度控制在300、400、500 mg/L附近时经过反应器后COD的去除效率进行了比较。通过公式计算的数据和实验数据分析可得:COD去除率的公式计算值与实验结果比较吻合,相对偏差仅为0.0223,为膜系统有机物的去除效果估算提供了基础,可为该类工艺的参数选择与优化提供参考。 |

| Abstract: | To predict the effluent quality in MBR processes,a mathematic model for removal efficiency in MBR processes was established,deriving from models standing for the chemical oxygen demand(COD) of the effluent with constant membrane flux.The model was also based on the dynamics characteristics of microbial growth and membrane separation.The experiment was carried out in a lab-scale to treat oily wastewater in a submerged membrane bioreactor(SMBR).Thereby comparisons between experimental data and imputed value were investigated at COD values of 300,400 and 500 mg/L.The results showed data good match of the COD removal efficiency between models and experiment,with a relative deviation of 0.0223,providing a foundation for estimating organics removing efficiency in membrane system and a recommendation for preferences and optimization of the processes. |
| Keywords: | membrane bioreactor microbial growth characteristics oily wastewater mathematical model |
