Environmental Impact Assessment of Groundwater in the Waste Lubricating Oil Storage Based on Analysis Method
Groundwater environmental impact assessment is an important work in the environmental impact assessment.Through data collection,hydrogeological survey,hydrogeological drilling,on-site hydrogeological test,water sample collection and testing,constructions of the water level and water quality monitoring well and other work,this paper obtains the hydrogeological conditions,hydrogeological parameters,water-bearing rock group characteristics,and groundwater quality in the study area.Assuming that the project is under abnormal working conditions,using the analytical model,to simulate the migration law of leakage pollutant solute in groundwater,predict the pollution degree of pollutant in groundwater environment,the diffusion influence range and migration trend in a certain time series.The results showed that the concentration of NH3-N and COD in groundwater exceeded the standard when domestic sewage was leaking.After 500 days,the concentration of NH3-N in groundwater does not exceed the standard,After 1 000 days,the concentration of COD in groundwater does not exceed the standard.When the production wastewater is leaking,the concentration of polluta nts such as oil and COD in groundwater exceeded the standard.After 1 000 days,the concentration of COD in groundwater does not exceed the standard.After 10 000 days,the oil pollutants in groundwater showed that they did not exceed the standard.
