采用描述浓缩过程的动态模型，对二次沉淀池在几种典型输入条件下瞬变过程的特性进行了模拟研究。结果表明，输入的变化幅度、方式和过程都可能影响瞬态响应的特性，并对达到稳态后的工况造成极大影响。模拟结果证实了模型能够描述污泥沿沉淀池深的分布，预测污泥浓缩性能和有关参数的变化，从而显示了它在活性污泥系统的工艺设计和运行控制研究中的应用价值
Using the dynamic model describing the concentration process, the characteristics of the transient process of the secondary sedimentation tank under several typical input conditions were simulated. The results show that the magnitude, mode, and process of the input change may affect the transient response characteristics, and have a great impact on the steady-state conditions. The simulation results confirm that the model can describe the distribution of sludge along the sedimentation tank depth, and predict the change of sludge concentration performance and related parameters, thus demonstrating its application value in the process design and operation control research of activated sludge systems.
