摘　　要：为分析入河排污口设置对太湖流域水环境的影响,以宜兴市工业污水处理厂为例,考虑排污口三种排放工况(尾水回用30%、未回用直接排放及事故时尾水全部排放),采用一维河网非恒定流水动力模型进行预测。结果表明,正常排放情况下,对各控制断面水质目标影响较小。事故情况排放时,将对下游造成不同程度的水质超标影响。研究成果可为太湖流域环境风险预测分析与评价提供依据,亦对优化排污口设置起到参考借鉴作用。In order to analyze the influence of sewage outlet setting on water environment of Taihu Lake Basin,taking Yixing industrial sewage treatment plant as an example,unsteady hydrodynamic model of one dimensional river network was used to predict the impact on water environment of the discharge outlet uner three working conditions:normal emission with 30%tail water reuse,direct emission without water reuse,and all tail water discharge in accident.The results showed that under normal discharge condition,the water quality target of each control section is less affected.In case of accident emission,the water quality in the downstream will exceed the standard in different degrees.The research results can provide a basis for the analysis and evaluation of the environmental risk prediction of Taihu Lake Basin,and play a reference role in optimizing the layout of sewage outlets.
