【摘要】 地下水环境影响预测是地下水环境影响评价中的重要环节,采取适合的预测方法和模型能够保证预测结果的准确性和环境保护措施的合理性。以某建设场地为研究区,利用GMS软件建立地下水预测模型,考虑风险事故工况条件下,预测了对二甲苯的污染运移范围。结果表明:装置一旦发生事故,污染物泄露将会对建设场地周边区域地下水造成污染,污染影响范围随时间逐渐增大,需采取严格的防范措施,并建立应急机制,保证当地居民的饮用水安全。更多还原

【Abstract】 The prediction of groundwater environment impact is an important link of groundwater environment impact assessment. The comfortable prediction method and model is ensure that accuracy of the prediction results and the rationality of environmental protection measures. GMS software was used to establish groundwater prediction model for a case study on the construction site. It was predicted that pollution transport range of xylene in the condition of the accident. The results show that groundwater in the vicinity area of the construction site will be contaminated,if accident happened in the device, the contaminating coverage will expand gradually with time.It’s ensure that the safety of drinking water to used strict preventive measures and to establish emergency response mechanism.更多还原
