Simulation Study On Actuality And Pollution Of Oil In Groundwater In Qilu Petrochemical Company

Human economic activities are leading to the deterioration of groundwater quality direct incentives. System environment groundwater pollutant type, concentration and distribution of the major sources of pollution depend on the features. In the investigation and mastery of the groundwater system and the main sources of pollution on the basis of this paper, through indoor simulated experiments explore the different nature of pollutants in the soil adsorption, migration and its impact; Discussion of pollutants in the groundwater movement-proliferation and its impact factors. The results showed:1. Oil pollutants to play a major role interception is one of the filling soil, limestone fissures adsorption role would retain more of the weak. Filling soil and limestone fissures of oil pollutants to meet the Langmuir adsorption process monolayer adsorption law.2. Sewage leaching experiments show that the vertical direction soil concentrations with the depth of oil were negatively index decrease. Oil layers of a strong retaining capacity. 117h by the leaching test, the layer of oil interception rate of 87.38%.3. Rainfall soil leaching of residual contamination of groundwater pollution serious and persistent. Seepage under the right soil residue, the average rate of dissolution: 9.2018mg/kg (oily soil)·L (seepage).4. Groundwater flow hydrodynamic conditions on the infiltration of groundwater contaminants have control of movement, but also by the surrounding environmental conditions and the nature of pollutants, the impact of concentration. The same velocity and groundwater pollutants between different density differences to the pollution plume migration have different effects. The higher the concentration of pollutants (greater density difference), the plume of pollution impact. Groundwater flow is, the role of hydrodynamic dispersion more powerful, the density difference between the smaller effects.5. Pollutant density difference will be on pollutants in the groundwater migration, proliferation produce different effects. For more than water density, big or small pollutants, only a concentration greater than 1.0mg/L or 10mg/L only need to consider.
