To reasonably plan out the scheme for the sewage discharge outlets of changshu fluorine chemical industry project, the article makes an ana lysis on the water environmental features of changshu section of the yangtze riv e, develops a plan two - dimensional model of coupled water flow - quality for its co mplicated underwater topography and stream flow - field. the model is relatively ac curate and practicable to predict the impact of scheme on water quality. varied s chemes have been compared and demonstrated from multiple angles, such as flow fie ld, impact assessment of water quality, technique and economy. the scheme of sewage discharge outlets away from the shore is recommended. the article provides a sci entific basis for the engineering design and envirommental management of the pro ject
為合理確定常熟氟化工項目排污口布置方案，本文在分析長江常熱段水環境特徵的基礎上，針對其復雜的水下地形和水流流場，建立了較為準確和實用的平面二維水流水質耦合數學模型，預測計算了三套方案污水對重點保護水域影響程度和范圍，並從水流流場、水質影響評價、技術經濟多角度對方案進行了比較論證，最終推薦污水江中排放的方案，為項目的工程設計和環境管理提供了科學依據。
