摘要
参照一维河流扩散模型,对污水管道中有害性气体的运动和分布规律进行建模分析,得出管道内有害气体分布的数学模型。采用Mathematica 9对数学模型进行分析,得出模型图像,进而得到3种典型的污水管道中有害性气体分布规律。对某市现有污水管道系统中甲烷气体的浓度进行实测,实测值与所得出的数学模型值吻合度较高,表明数学模型能够较准确地预测管道中有害气体的分布。
Referring to the one--dimensional river diffusion model, the movement and distribu- tion of harmful gases in sewage pipeline were modeled and analyzed, and a mathematical model of harmful gas distribution in pipeline was established. Modelling images were created by using the mathematic model with Mathematica 9, and the distribution of harmful gases in three typical types of sewage pipelines was obtained. The methane gas concentrations in the existing sewer system of a city was measured and compared with the modelled values. The measured data were in good agree- ment with the modelled values, indicating that the mathematical model can accurately predict the distribution of harmful gases in pipelines.
