摘要
通过太湖的水量水质数学模型,模拟了梅梁湾内主要的入湖污染源———直湖港、武进港和梁溪河排入的污染物质的迁移、转化规律;分析了梅梁湾中梅园、小湾里、闾江口、拖山4个监测点水质浓度受直湖港、武进港和梁溪河排污影响程度的大小;并分别建立了监测点污染物浓度与排污口排污量的响应关系曲线和响应关系表达式。通过这些结论可以方便的定量的计算出在排污口排污量发生变化的情况下监测点水质浓度的变化量,为合理控制外源污染物质的入湖量提供了技术支持。
The law of transfer and conversion of pollutant,which come from the primary pollutant source including Zhihu port,Wujing port and Liangxi river in Meiliang Bay,was simulated using the mathematical model of water flow and water quality of Taihu lake.The incidence proportion between the four monitoring points' concentration and discharge capacity of those pollutant source was analyzed,and the response relation curve and response relation expression were also established in this paper.By using these conclusion,the variation of the monitoring points' concentration can be calcueculated conveniently,which can provide technical support for controlling the extraneous sources pollutant quantity inflowing to Taihu lake.
