华北地区土壤中石油类污染物的迁移渗透规律研究

Study On Migration and Penetrating Law of Petroleum Pollutant in Soil in North China

针对华北地区的地理环境,以胜利油田为例,分别采用室内淋滤试验法和野外取样分析法讨论了华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。

The migration and penetrating law of Petroleum Pollutant in Soil in North China produced in the process of oil exploitation,taking Shengli oilfield as an example,was studied by the indoor leaching experiment and the outdoor sampling analysis,and their preventing and controlling measure was discussed.Due to the adsorption of the soil,the Petroleum pollutant mainly exist in the 80cm upper soil layer,which is a great influence on the surface soil.The polluting area could be decreased by the construction of oil-gathering pool and the treatment of anti-seepage and landfill.
