摘要
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。
Transient responses of a secondary charifier to changes in simulating several typical input conditions are studied,based on a dynamic model which can trace out sludge thickening process.Results show that the extent,pattern and duration of the input condition changes can affect responses characteristics,and will have a significant effect on the steadystate behiviors after the transient responses.The dynamic simulation demonstrates its capacity to describe sludge consistency distribution along the tank depth and to predict sludge thickening process and time consistency profiles in the clarifier,thus showing the value of applying the dynamic model to process design and operational control study of activated sludge system.
