【摘要】：為分析南通市通州區(qū)新江海河地區(qū)不同引水方案下的水質(zhì)改善效果,采用一維圣維南方程組和對流擴(kuò)散方程,以水量模型和水質(zhì)模型間流量、水位資料的信息傳輸廊道為媒介,構(gòu)建水量水質(zhì)耦合模型,通過控制南通閘引水量,模擬分析了不同引水方案對新江海河各斷面CODcr和氨氮濃度變化的影響。結(jié)果表明,由于新江海河水動力條件不足,污染物本底濃度較高,導(dǎo)致工程引水對其水質(zhì)改善效果有限,針對其水質(zhì)污染特點(diǎn),提出了加強(qiáng)控制污染物入河量的建議,為當(dāng)?shù)厮こ陶{(diào)度工作和改善新江海河水體水質(zhì)提供了依據(jù)。
[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.
