大沽河干流青岛段水环境容量研究

Study on the Water Environmental Capacity of the Mainstream of the Dagu River(Qingdao Reach)

本文根据大沽河的水流特性和水文、水质实测资料 ,利用 QUAL2 E综合水质模型 ,分析确定了大沽河干流丰水期和平水期的水环境容量。又利用水库水环境容量的计算方法 ,确定了大沽河干流枯水期的水环境容量。大沽河干流水环境容量的确定 ,可用于河流的水质模拟和预测 ,为实施大沽河污染物总量控制提供基础资料 。

In this paper based on the flow characteristics, hy drological data and water quality data of the Dagu River, the water environmenta l capacity of the mainstream of Dagu River is analyzed and calculated in the hi gh water and par water periods using the comprehensive water quality model, QU AL2E, and also has been calculated in the low water periods using a water envir onmental capacity model for reservoirs. The method used in this paper is capabl e of simulating and forecasting the water quality, providing basal data for t otal pollutants control and scientific basis for pollution management.
