200 立方米每小时水泵提升式调量池建模与设计摘要污水处理要求运行平稳，各种运行参数都好控制，以降低运行成本。在此过程中，调节池的作用尤为突出。调节池是指调节水量和水质的构筑物，它的作用是对水量和水质的调节，调节污水 pH 值、水温，有预曝气作用，还可以用作事故排水。本课题通过改进已建立的泵提升式调量池的数学模型进一步讨论进水量发生变化时调量池水位以与泵的出流量随时间的变化过程。通过实体模型实验讨论数学模型中涉与到的、可能对泵的出流量产生影响的因素，并验证推导的数学模型的可行性。本课题通过实验和模拟得出的结论，对现有池型进行改造和分析，发现可能存在的问题，并提出改进措施，完成泵提升式调量池的优化设计。根据实验结果，得出以下结论：（1）建立了进水量发生变化时调量池水位以与泵的出流量随时间的变化的数学模型；（2）调量池的水位与管道 S 值是影响泵出流量的重要因素；（3）根据数学模型，工程实际中应使泵在其高效段出水；（4）工程实际中泵提升式调量池的池底面积尽可能大一些；（5）根据数学模型表达式是否有意义可以估量泵提升式调量池可以调节的水量围。关键词：泵提升式调量池、水量波动、稳定出流、数学模型、仿真模拟AbstractSewage disposal requires smooth operation and all kinds of operation parameters are under good control in order to reduce operation cost.During the process, the role of regulating pondage is excessively outstanding. Regulating pondage is one kind of structure that can be used to regulate water quality and quantity, sewage pH value, water temperature and preaeration.It also can be used to accident drainage. By improving the mathematical model of pump ascension adjustable volume pool that has been established, we research the change process of water level and pump discharge when the water inflow varies from the time. Through entity model experiment we research factors that possibly affect the pump discharge that is related to the mathematical model. And we also validate feasibility of the mathematical model. According to the conclusion from experim...
