摘　　要：对淹没式膜生物反应器(SMBR)处理中药废水进行了中试研究,并基于ASM1号模型建立了膜生物反应器内有机物和氮同步处理的数学模型。根据SMBR反应器内污泥的生化特性和污水特性对ASM1号模型进行了修正。采用1阶偏微分方程组表示了SMBR反应器内有机碳和氮的转化过程,并利用MAT-LAB软件应用模型对不同溶解氧浓度条件下的MBR处理过程进行了模拟。结果表明:模拟值和试验值符合较好,模型中采用的参数可较好的描述有机碳和氮的转化过程。模型可用于评价处理效果和模拟操作过程,并为优化SMBR设计和运行参数提供参考。A mathematical model of simultaneous organic carbon and nitrogen removal has been developed for a pilot submerged membrane bioreactor （SMBR） based on the activated sludge model No. 1 （ASM1） for pharmaceutical wastewater treatment. The ASM1 was modified to take account into physicochemical and biological properties of the wastewater and sludge in the SMBR. Ten additional 1st - order linear differential equations were established to describe the organic carbon and nitrogen removal synchronously in SMBR simulation program of SMBR process was compiled using MATLAB mathematics software on a personal computer. And the model developed was applied to the membrane bioreactor process with different dissolved oxygen （DO） concentration under continuous aerobic operational condition. The agreement of simulation results with the experimental data indicated that the coefficients used in the model could successfully describe the organic carbon and nitrogen treatment performance. The most advantage of this modified model over the conventional one was that this model could evaluate treatment performance and simulate the operation of the SMBR. The model developed in this study would provide a useful tool in optimizing operational conditions as well as design parameters for a SMBR system.
