摘要
为了更好的对河流水体污染进行控制和治理,及时了解河流的水质状况是必要的。河流水质预测是了解河流水质污染趋势的重要手段。利用一维水质模型来近似模拟河水的水质状态,采用有限差分法对模型进行求解,从而预测河流中污染物浓度。以淮河淮南段为例进行验证,证明了采用一维水质模型对河流水质进行预测是可行的,利用有限差分法求解一维水质模型完全满足实际应用对误差的要求。
To better control and prevent water pollution in rivers,it is necessary to know the conditions of water quality in rivers in time. The water quality prediction is an important means for understanding the tendency of water pollution. An one-dimensional model is used to approximate and simulate the conditions of water quality,and a finite differential method is deployed to solve the model to predict the concentration of contaminants in rivers. Huainan area in Huaihe River is used for example for proving the water quality. It is demonstrated that the model is feasible for water quality prediction,the differential method for solving the model is satisfied with the errors of application.
