摘要
以云南某化工厂为研究对象,在详细调查区域水文地质条件和充分分析研究区地下水污染源、污染途径的基础上,利用GMS软件建立地下水水流模型及溶质运移模型。模型预测了硝酸盐在泄露污水总量的1%、5%、10%三种情景下持续泄露120d以及切断污染源后残留污染物运移100d、300d、600d、1 000d污染物的迁移规律、污染范围和浓度分布情况。结果表明:污染物在地下水中迁移缓慢,最大迁移距离100m左右。当污染物泄露浓度持续上升,运移距离及污染面积会增大,危及下游夹马石、白沙坡等村庄饮用水安全。
Taking a chemical plant in Yunnan as the research object,based on the detailed investigation of regional hydrogeological conditions and adequate analysis of groundwater pollution sources and pollution pathways in the study area,using GMS software to establish groundwater flow model and solute transport model.The model predicts the migration of nitrates in the 1%,5%,and 10% of the total leakage of sewage for 120 days and the migration of pollutants after 100,300,600,and 1 000 days of residual pollutants.Pollution range and concentration distribution.The results show that the pollutants migrate slowly in groundwater,and the maximum migration distance is about 100 meters.When the concentration of pollutants continues to rise,the migration distance and the area of pollution will increase,threat the safety of drinking water in villages such as the Jiamashi and Baishapo.
