Forecast and Risk Assessment of Groundwater Pollution in a Chemical Plant in Huai'an City, Jiangsu Province
摘要
Abstract
[Objective] The risk of groundwater pollution was evaluated,in order to provide a simple and effective new method for groundwater pollution forecast and risk assessment of both similar construction projects and enterprises' independent environmental impact assessment.[Methods] A solute transport model based on the mathematical model of solute transport was established to predict the pollution levels of CODMn and Ni.And a risk assessment method for groundwater protection was developed to evaluate the groundwater contamination risk.[Results] After 100 d of a sudden accident,the maximum migration distance of CODMn was 11.6 m,for Ni,it was 10.8 m,having 8.8 m and 8.0 m spreads beyond the boundary of this factory,respectively.The monitor well W2 was determined as higher pollution risk level,and W3 as middle pollution risk level.[Conclusion] Pollutants such as CODMn and Ni in the groundwater diffuse rapidly,affect water quality seriously,so that track monitoring should be strengthened and the impermeability should be checked regularly.关键词
