电厂灰场对地下水污染的数值模拟及污染预测——以江苏徐塘电厂炮车灰场F-污染为例

Numerical Simulation and Prediction for Groundwater Pollution near Waste Ash Ponds of Coal fired Power Plant——A Case Study for F - Pollution in Paoche Ash Ponds of Xutang Power Plant,Jiangsu Province.

以江苏徐塘电厂炮车镇灰场为例，建立了炮车镇灰场及邻近地区地下水水质（污染）模型，并选用灰渣溶滤后产生的Ｆ－作为模拟因子，对地下水水位变化和Ｆ－浓度变化进行了数值模拟．最后利用模型对地下水中Ｆ－污染的范围和程度进行了预测．结果表明，模型可靠、合理、实用。

A 2 dimensional pollutant transport model for groundwater pollution in the aquifer near ash ponds of Xutang Coal fired Power Plant was established in this paper,and selecting F - as the simulating factor,the variations of groundwater hydraulic heads and F - concentration were simulated.At last,the polluted area and pollution,degree of F - were predicted by the model.According to the simulating results,the model is reasonable,reliable and practicable.It provides a scientific method to predict the polluted area and pollution degree caused by the waste ash ponds.
