解析法在地下水环境影响评价中的应用研究

The Application Study of Analytical Method to Environment Impact Assessment of Groundwater

在详细研究当地水文地质条件的基础上,本文利用解析法对泰州市某污水处理厂非正常工况下泄露到地下水中的Ni进行了环境影响预测评价。结果表明,Ni对污水处理厂所在区域地下水目标含水层造成了一定程度的影响,并且存在超标现象,但不会影响污水处理厂附近的保护目标和地下水敏感区域。Ni超标及影响范围总体呈先增大后减小的趋势,该研究成果可为今后的地下水环境影响评价提供相应的参考。

In this paper, analytical method is used to environment impact assessment of groundwater based on a detailed study of the hydrological conditions around a some wastewater treatment plant. The results show that： the Ni causes pollution of the aquifer during the simulation period, and there is excessive phenomenon, but it will not cause obvious impact on the conservation objectives. The exceeding and affected area increases first and then decreases. The paper can provide a few references for the assessment of groundwater in future.
