走马塘工程对“引江济太”水源地水环境影响研究
Influence of Zoumatang Project on the Water Environment of Water Source Area of "Water Diversion from Yangtze to Taihu" Project
摘要
Abstract
In order to study the influence of pollution discharge of Zoumatang Channel of Yangtze-Taihu Water Diversion on the water quality of the source area,a three-dimensional fluid hydrodynamic model of Cheng Tong section of Yangtze River was estabhshed based on EFDC model.The model was calibrated and validated by the field measured tidal and velocity data.The simulated result showed that calculated values are consistent with the measured values,and the model has good ability of simulation precision and prediction..This paper simulated the influencing range of the sewage diffused in Zoumatang Channel in dry season and wet season using CODMn as the index.The results indicated that the diffusion range is larger during ebb tide period than that during flood tide period,and in dry season,the diffusion range is larger than that in wet season.Beside,wet season is more conducive to the dilution and diffusion of sewage.Throughout the whole simulation period,the water quality of the diversion intake of Wangyu River meet the requirements in scheduling and planning program stipulated by Taihu Basin Agency,with the concentration of CODMn in water source area not higher than 6 mg/L.关键词
