摘要
根据NAPL态石油类污染物迁移的特点 ,建立了NAPL态石油类污染物在土壤中迁移的稳态数学模型 ,提出了综合污染系数的概念 ;根据延安黄土高原地区土壤和石油类污染物的特性测定了NAPL态石油类污染物对黄土的综合污染系数S =6～ 8。最后在实验室条件下对模型进行了验证 ,结果表明模型计算值与实验值能够较好吻合。
A transport mathematical model of NAPL petroleum pollutants in yellow soil was set up in term of the transport characteristics of petroleum pollutants in soil. And the concept and definition of comprehensive pollution coefficient was given. Moreover, the value of the comprehensive pollution coefficient was found amid 6～8 by the related experiments. Then transport mathematical model of NAPL petroleum pollutants was testified under the condition of laboratory. The results showed that the transport mathematical model of NAPL petroleum pollutants accorded well with the experiment results.
