| 中文摘要 |
| 数学模拟是污水处理系统教学科研、工艺评估、运行优化和自动控制的重要工具,在污水处理厂中得到了广泛应用. 利用过程数据对ASM2d模型进行校正,并分析评估了校正模型在多模式厌氧/缺氧/好氧(AAO)工艺3个模式15个工况下稳态模拟及AO模式下动态模拟的可靠性. 15个工况的稳态模拟表明,校正模型能准确模拟污泥浓度和出水水质; 在AO模式的动态模拟中,模拟曲线与出水水质以及污泥浓度的变化趋势相一致,模拟结果具有较高的准确度. |
| 英文摘要 |
| Mathematical modeling is a useful tool for professional education, process development, design evaluation, operational optimization and automatic control of the wastewater treatment system, and has been extensively applied in numerous full-scale wastewater treatment plants. The ASM2d model was calibrated by the process data, and used to simulate 15 operational test runs of the multimode anaerobic/anoxic/aerobic (AAO) process. After calibration, the model was capable of simulating the sludge concentrations and effluent data in 15 test runs of the multimode AAO system. The dynamic simulation results showed an overall good agreement between the measured and simulated data, for both effluent data and sludge concentrations, with a good reproduction of dynamic processes in AO test runs. |
