反求扩散系数在地下水水质模型计算中的应用

Application of Inversely Derived Diffusion Coefficient in Underground Water Quality Model Calculation

结合灞桥热电厂技术改造工程环境影响评价,利用原有灰场灰水下渗影响的实际水质监测资料,运用地下水水质模型,反求地层的扩散系数。预测电厂技术改造后,灰场灰水下渗对灰场下游地下水水质的影响,实现水环境影响的定量评价。

Combining with the environmental impact evaluation of retrofitting project of Baqiao Cogeneration Power Plant ,by using the practical water quality monitoring data on the ash slurry water infiltration impact of the original ash yard,and utilizing underground water quality model,this paper in versely derives the diffusion coefficient of stratum,and forecasts the impact of ash slurry water infiltration in ash yard on the underground water quality at the downstream of ash yard after the retrofitting of power plant ,thus realizes the quantitative evaluation of water environmental impact.
