【摘要】：为分析南通市通州区新江海河地区不同引水方案下的水质改善效果,采用一维圣维南方程组和对流扩散方程,以水量模型和水质模型间流量、水位资料的信息传输廊道为媒介,构建水量水质耦合模型,通过控制南通闸引水量,模拟分析了不同引水方案对新江海河各断面CODcr和氨氮浓度变化的影响。结果表明,由于新江海河水动力条件不足,污染物本底浓度较高,导致工程引水对其水质改善效果有限,针对其水质污染特点,提出了加强控制污染物入河量的建议,为当地水利工程调度工作和改善新江海河水体水质提供了依据。
[Abstract]:In order to analyze the effect of water quality improvement under different diversion schemes in Xinjianghai River area, Tongzhou District, Nantong City, one-dimensional Saint Venan equations and convection-diffusion equations are adopted. The information transmission corridors between water volume model and water quality model are used as the media. The coupling model of water quantity and water quality was constructed and the influence of different diversion schemes on CODcr and ammonia nitrogen concentration in each section of Xinjiang River was simulated and analyzed by controlling the diversion amount of Nantong sluice. The results show that due to the shortage of dynamic conditions and the high background concentration of pollutants, the effect of engineering diversion on improving water quality is limited. According to the characteristics of water quality pollution, some suggestions are put forward to control the amount of pollutants entering the river. It provides the basis for the local water conservancy project regulation and the improvement of the water quality of Xinjiang River and Haihe River.
