合肥市南淝河水环境容量研究

根据南淝河的水文资料,选用一维稳态模型来模拟水质。以河段的功能分区情况为基础,利用已建立一维稳态的模型,选择段首控制法,对南淝河主要污染物CODcr,TP,NH3-N三项指标在不同水情保证率下进行环境容量的计算,并结合实际排放情况计算出削减量。南淝河水环境容量的确定,可用于河流的水质模拟和预测,为实施南淝河污染物总量控制提供基础资料,为南淝河水污染控制的管理和决策提供科学依据。

Research on water environmental capacity in Nanfeihe River in Hefei city

Based on the hydrographic data of Nanfeihe River, the water quality model is established by the use of a one dimensional model. On the ground that environmental function area is sectioned, the environmental capacity for major pollutants such as COD, TP and NH_(3)- N of the Nafeihe river are calculated and analyzed with the established water quality model under the condition of different flow frequencies.The method used in this paper is capable of simulating and forecasting the water quality, providing basal data for total pollutants control and scientific basis for pollution management.
