| 摘 要： | 选用NaCl作为示踪剂,对土地处理系统上向流和下向流两种流动方式下的水力特性进行研究,结果发现上向流的水力死区较小为8.77%,且流型更接近推流式。进而对系统实际流态进行数学模拟,研究发现对分散模型进行修正,自行建立的双参数模型能够较好的拟合土地处理系统的流动形态。

| Abstract: | Using NaCl as tracer,the test studied the fluid state of the land treatment system about upward flow and downward flow.It was found that hydraulic dead zone of upward flow was lesser to 8.77% and its fluid state characteristic was closer to plug flow.Actual fluid state of the system was mathematical simulated.It was found that two-parameter model which dispersion model was amended to establish was more effective to simulate fluid state of land treatment system. |
