西北地区土壤中石油类污染物的垂直渗透规律

针对西北地区独特的地理环境，讨论了西北地区油田开发过程中产生的石油类污染物在土壤中的迁移渗透规律及防治措施。由于土壤的吸附作用，石油类污染物主要积聚在土壤表层80cm以内，对表层土壤影响较大。可以采用修建收油池、防渗填埋的处理方法，减少其污染范围。

A vertical transfer regularity of oil pollutant in the soil of the northwest

Be aimed at the special geography environment of the Northwest, a transfer regularity of oil pollutants in the soil and how to prevent it during the oil field exploit in the Northwest was studyed. Because of the adsorption of soil, the oil pollutants were main gathered within 80 cm of the soil surface. It quite effected the surface of soil. Therefore we could build the oil pond or fill the oil pollutants to the pond preventing seepage so as to reduce the pollution range.;
