数值法在地下水环评中的应用

Application of Numerical Method in Groundwater Environmental Impact Assessment

利用数值法对鹤壁市某建设项目配套的污水处理站非正常状况下泄露到地下水中氨氮的运移规律进行了模拟研究,结果表明:模拟期内,氨氮泄露后在地下水中有一定的超标现象,但其影响范围在水平方向上仅限于厂区附近,垂向上仅在潜水含水层,该研究结果可为今后的地下水评价提供参考。

In this paper,a numerical method is used to simulate the migration of ammonia nitrogen from a sewage treatment station to groundwater under abnormal conditions in Hebi City.The results show that during the simulation period,ammonia nitrogen leaks out of groundwater to a certain extent,but its influence range is limited in the horizontal direction.Near the factory area,it is vertical only in the phreatic aquifer.The research results can provide reference for groundwater evaluation in the future.
