基于Visual MODFLOW的某制药厂地下水环境预测研究

Prediction of groundwater environment of a pharmaceutical plant based on Visual MODFLOW

制药工业产品种类多,生产工艺复杂,产生的"三废"量大,废物成分复杂,一旦发生泄漏,将对地下水环境造成影响。应用Visual MODFLOW软件模拟了某制药厂运营期可能产生的污染物在地下水环境中的溶质运移情况,结果表明:非正常工况下,污染物会对潜水含水层造成影响,并存在超标现象,但是随着污染物的扩散,超标面积逐渐缩小至零。据此提出防控措施。

As pharmaceutical industry has many kinds of products, the production technology was complicated, large amount of "three wastes" with complex components were produced, which may impact groundwater environment in case of leak. Using Visual MODFLOW software to simulate the solute transport situation which may happens to the pollutants in the groundwater environment during the trial operation period of a pharmaceutical plant. The results showed that, under abnormal operation condition, pollutants would affect unconfined aquifer and exceeded the standard, however, with the pollutants diffusion, overproof area gradually reduced to zero. In view of the above situation, the prevention and control measures were put forward.
