中文摘要：

研究了生物活性炭（BAC）工艺去除含油废水中石油污染物的动力学过程。以物质扩散机理和米氏动力学为基础，建立了BAC处理石油污染物的动力学模型，并对BAC工艺中吸附和生物降解石油污染物效果的实验数据和模型预测值进行了比较。研究结果表明BAC工艺处理含油废水是可行的，BAC工艺运行稳定后，去除率可达80％以上，出水效果良好。BAC模型的预测结果和实验结果基本相符，BAC工艺对石油污染物的降解作用不是简单的活性炭的吸附和石油降解菌生物降解的叠加，而是两者共同协作完成的，并实现了活性炭的生物再生。BAC动力学模型为BAC工艺处理含油废水在工程应用中提供了相关的理论基础。

英文摘要：

The kinetics process of removing oil-contaminant in oil-bearing wastewater by biological activated carbon （BAC） procedure was investigated. Based on the mechanisms of mass diffusion and Monod kinetics, the kinetic BAC-model was established to describe the oil-contaminant treatment process. The kinetic BAC-model predictions and experimental results for simultaneous adsorption and biodegradation of oil-contaminant were compared. This study demonstrated that oil-bearing wastewater treatment by BAC-process is feasible. The oil removal rate could reach over 80% when the BAC procedure is at a steady-state condition. The BAC-model predictions basically are in agreement with the experimental results. It is shown that the fundamental mechanisms of BAC-process in oil remov- al are not simple addition but the synergetic combination of activated carbon adsorption and biodegradation of oil- degrading strains, and at the same time, active carbon is bioregenerated by the oil-degrading strains. This kinetic BAC-model can provide a theoretical foundation for BAC-process to treat oil-bearing wastewater in engineering ap- plication.
