The concentrations of heavy metals Zn and As in acid wastewater from copper smelting are high,and leakage will penetrate into the regional groundwater environment,which will have an adverse impact on the groundwater environment.The one-dimensional convective diffusion model was used to predict the groundwater infiltration environment under the acci-dent state of copper smelting acid wastewater.The pollutants migrated downstream with the groundwater,and the pollution front of the characteristic pollutants As and Zn needed 609 and 751 days to migrate 500 m,respectively.It takes 6 292 days and 7 086 days to migrate 2 300 m,respectively.The prediction conclusions can provide reference for groundwater control in similar enterprises.
