常熟市洪洞水质净化厂尾水排放环境影响研究OA

The study highlighted the environmental impact model for tail water discharge from a water purification plant in Hongdong County,Changshu.Based on a thorough investigation of the natural hydrometeorological environment,river systems and hydraulic engineering in Changshu,the water quality model of river network was established by using MIKE11,and the model was calibrated and verified based on the accumulated water quality and quantity data.The model was then used to calculate and analyze the impact of the operation of Hongdong County water purification plant on the water quality of the surrounding river network under both normal and accident discharge conditions.The article also analyzes in detail the transport law of pollutants in the Changhu River estuary and the influence of the operation of the purification plant on the Yangtze River water functional zone.Based on the above analysis and calculation,it is clear that the location of the Hongdong County water purification plant is feasible,and that the environmental impact of the project on the water quality of the surrounding river network can be controlled after its operation,which is conducive to the improvement of the water quality of the Yangtze River.
