| 摘 要： | 针对淹没式MBR的工艺特点，以反应器内物料衡算为基础，建立了有机物去除的动力学模型——ROM模型，得出淹没式MBR对有机底物的去除速率Uy不仅与进、出水中的有机底物质量浓度S0、Sc和水力停留对间tH有关，还与膜组件去除的有机底物质量浓度Sm、污泥停留时间ts有关．利用ROM模型，可以预测反应器内活性污泥浓度X，确定污泥停留时间ts和不排泥条件下反应器内的最大活性污泥浓度Xmax,试验中以啤酒厂废水为例，对模型进行了验证，试验结果与模型计算结果基本一致．

| Abstract: | A ROM model, a kinetics model of organic substrate removal for submerged membrane bioreactor was established on the basis of material balance.According to the model, the organic substrate removal rate is determined not only by the organic substrate concentrations of influent and effluent and hydraulic retention time (HRT), but also the organic substrate concentration removed by membrane modules and sludge retention time (SRT). Meanwhile, SRT and the maximum mixed liquor volatile suspended solids (MLVSS) value without discharging sludge can be determined as well as the concentration of MLVSS can be predicted in the reactor. Brewery wastewater was chosen and examined to verify the model and the results showed that the experimental data were coincident with the calculating data. |
