摘要
针对农业排水沟渠系统中磷的迁移转化机理不清楚,运移模拟少的问题,本文以沟渠中水体为研究对象,通过分析排水沟渠的生态结构,得出总磷在排水沟渠系统内迁移转化过程。将水流连续方程、污染物迁移转化方程组成模型,运用模型和获得的参数进行了排水沟渠的试验,对总磷的指标进行模拟,最后模拟出的结果与样品实测值吻合比较好,模拟系数更是达到了0.9,构建的模型适合此类封闭式沟渠。
In view of the unclear mechanism of phosphorus migration and transformation,and less migration simulation in agricultural drainage ditch system,this paper takes the water body in the ditch as the study core in order to analyze the ecological stucture of drainage.The migration and transformation process of total phosphorus in the drainage ditch system is obtained,and the model is composed of flow continuity equation and pollutant migration and transformation equation.The experiment of drainage ditch is carried out by using the model and the obtained parameters.The index of total phosphorus is simulated.Finally,the simulated results are in good agreement with the measured values of the sample,and the simulation coefficient is up to 0.9.The model is suitable for this kind of closed ditch.
