工业废物处理场地下水污染物运移模拟与预测

Groundwater pollutants migration simulation and prediction for industrial waste treatment site

以枝江市姚家港工业园区拟建的工业废物处理场为例,建立相应的污染物迁移模型,在非正常工况下,选取典型污染物指标Ni,对场区的污水处理厂和填埋区进行污染物迁移预测。模拟结果表明:在非正常状况运营期内,超标污染晕都呈现逐步扩大的趋势,浓度逐渐增高,污染晕向东南部扩散,运移出场界,未到达长江。因此,拟建厂区对区域地下水影响在可接受范围内。

Taking the industrial waste treatm ent site to be constructed in Yaojiagang Industrial Zone of Zhijiang City as example,pollutant migration model was set up correspondingly.Pollutant migration prediction under abnormal operating condition was conducted with a typical pollutant index of Ni for the sewage treatm ent plant and landfill area.The results of simulation demonstrate that excessive pollution halo expands toward southeast with a density in creasing gradually,until moving out of the site border,without reaching Changjiang River.Therefore,it is concluded the waste treatm ent site to be constructed will lead to acceptable influence on regional groundwater.
