摘要
首先建立太湖流域平原河网区水环境容量模型,然后据此计算苏南地区往复流河道典型水文年的水环境容量COD值,最后结合污染源削减预测,分析太湖流域苏南地区部分河道未来水质的达标情况.结果表明,所计算的太湖流域苏南河道剩余环境容量基本上为负值,其中苏南各运河为苏南河网水域的主要纳污河道.
A water environment capacity model is established for plain river network region in the Taihu Lake Basin. By use of the model, the COD value of water environmental capacity in typical hydrological years is calculated for reversing current channels in the south Jiangsu Province. In combination with the prediction of the reduction of pollution sources, the up-to-standard situation of the water quality of the river channels in the Taihu Lake Basin in the future is analyzed. It is shown that the calculated results of the residual environmental capacity of the river channels are basically negative values, and the canals of the south Jiangsu Province become the main pollutant receiving channels.
