| 摘 要： | 导出与分析了不同混合条件下，活性污泥生物反应器的动力学模型。以此为基础，模拟了不同活性污泥法的动力学过程，并讨论了计算结果。研究结果表明，在相同的条件下，推流型反应器性能优于完全混合型反应器，但这一差别随反应时间的增加而减少，4阶以上的CSTR性能与PFR相接近。分析表明，在做CSTR的设计计算时，不能同时设定污泥龄或出水基质浓度。同时，污泥龄不宜直接用于计算PFR。因篇幅所限，全文分为两节，本节主要讨论CSTR和阶式CSTR动力学模型。

| Abstract: | This paper models and analyses the dynamics of activated sludge wastewater treatment reactors in different mixing patterns. It is demonstrated that the performance of PFR (plug flow reactor)is superior to the performance of CSTR (continuous stirred tank reactor),but the difference between them will decrease with HRT (hydraulic retention time) extended and the 4 tages CSTR in series is similar to PFR in performance. It is also demonstrated that MCRT (mean cell retention time) and substrate concentration of effluent can't be set at the same time for designing of activated sludge reactor, and also that the attempt is unsuitable to design PFR by inducing MCRT directly.The full paper is divided to two sections, the dynamic performance of CSTR and multi stage CSTR are discussed in this one mainly. |
