环境影响评价中多排口河段水质预测研究

Research on Prediction of Water Quality of River Sections with Multiple Polluted Inflows in Environmental Impact Assessment

环境影响评价导则所推荐的水质预测模型在实际工作中有时显得有些简单,实际情况是要预测拥有复杂结构的多排口的河道污染带分布。因此,通过建立平面二维水质模型数学模型,并以某具体城市河流为例,计算得出了河段污染带分布情况。计算结果有较好的精度,能为环境影响评价工作提供一定的科学依据。

In practice the model for water quality prediction recommended by the Manual for Environmental Impact Assessment is too simple to cover the more complex conditions of the river sections with multiple polluted inflows. So the new model will be needed to forecast water quality in the fiver. Establishing a 2 D water quality model and using it to compute pollute distributing in the urban river. The result can provide scientific gist for city planning.
