中文摘要：
通过在沉淀池-维分层模型中纳入弥散项和异重流，建立沉淀池-维分层水力模型，并选用Takfcs模型描述沉淀池中悬浮固体的沉降速率．根据沉淀池的运行特性，结合污泥层高度的算法，建立模型参数校核的评价指标．针对模型中参数较多、校正困难的问题，利用经验公式率定结合灵敏度分析的方法，提出了通用的参数校核方案．参数校核后的沉淀池模型，能够很好地模拟中试试验实测的悬浮固体曲线、出水和底流的悬浮固体质量浓度和污泥层高度．
英文摘要：
A one-dimensional （1D） layered and hydraulic settler model with Takdcs settling velocity model was constructed by the incorporation of dispersion item and density current. Evaluation indices for parameter calibration were put forward based on sludge blanket height （SBH） algorithm and the operational characteristics of settlers. A general parameter calibration protocol was advanced by empirical formula estimation together with sensitivity analysis for the settler model with multiple parameters. With parameter calibration, the settler model fits well for SS profile, overflow and underflow SS concentrations, and SBHs measured in three pilot-scale settler tests.
