基于ASM3模型的一体式MBR出水水质模拟分析

摘要

将活性污泥3号模型(ASM3)与一体式MBR结合,采用Matlab/Simulink自行开发了可视化的仿真模拟程序,构建了活性污泥系统模型.将此程序应用于一体式MBR工艺,对其进行了稳态模拟、灵敏度分析和参数校正,并取得了与实测值较为一致的结果.同时利用模型分析了不同进水水质下反应器的出水水质结果,模拟结果与实际状况吻合较好.%Combined the activated sludge model No. 3( ASM3) with the submerged MBR, an activated sludge system was constructed based on the self-developed simulation program of Matlab/ Simulink. By applying this program to the performance of the submerged MBR, the simulation results were consistent with the measured values in the steady state simulation sensitivity analysis and parameter correction. In addition, using the model to analyze the effluent quality of the reactor under the different condition of the inflow water quality, the simulation results were also fairly coincided with the measurements.
