Activated sludge model No. 1 (ASM1) and activated sludge model No. 3 (ASM3) can simulate correctly the behaviour of a pilot membrane bioreactor treating old landfill leachates. Both models show similar results, which are consistent with measured data. In this work, a simplified calibration procedure is applied including hydrodynamic and oxygen transfer characterization. The wastewater characterisation was based on a physical–chemical method combined with a BOD analysis for the COD fractions and on standard analysis for nitrogen forms. Default parameters were used for both models; despite this, good simulations were obtained showing the flexibility and accuracy of the well-achieved ASM family models. The sensibility analysis performed allows identification of the most important kinetic, stoichiometric and operational parameters that should be measured to confirm or replace default values. In this specific case, the simulation is most sensitive to heterotrophic yield, particularly under anoxic conditions.

用活性污泥模型 1 和 3 模拟膜生物反应器中试处理旧垃圾渗滤液

活性污泥模型 1 (ASM1) 和活性污泥模型 3 (ASM3) 可以正确模拟中试膜生物反应器处理旧垃圾渗滤液的行为。两种模型都显示出相似的结果，与实测数据一致。在这项工作中，应用了一个简化的校准程序，包括流体动力学和氧气传输特性。废水表征基于物理化学方法，结合 COD 部分的 BOD 分析和氮形式的标准分析。两种模型均使用默认参数；尽管如此，还是获得了良好的模拟，显示了实现良好的 ASM 系列模型的灵活性和准确性。执行的敏感性分析可以识别最重要的动力学，应测量以确认或替换默认值的化学计量和操作参数。在这种特定情况下，模拟对异养产量最敏感，尤其是在缺氧条件下。
