摘要
土壤地下水石油类污染依然普遍且严重。季节性冻土区土壤经历冻-融-冻过程,石油类污染物与土壤地下水作用过程更为复杂。文章综述了冻融交替对土壤理化性质的影响,以及由此引起的土壤中石油类污染物吸附解吸、生物降解过程变化,为季节性冻土区石油类污染物迁移转化的研究治理提供支持。
Petroleum pollution in soil and groundwater is still widespread and serious.With the freezing-thawing-freezing process of seasonal frozen soil,the interaction between petroleum pollutants and soil groundwater is more complex.In this paper,the effects of freeze-thaw cycles on soil physical and chemical properties were discussed,meanwhile,the adsorption and desorption of petroleum pollutants in soil and the changes of biodegradation process caused by freeze-thaw cycles were reviewed,which provided supports for the migration and transformation of petroleum pollutants in seasonal frozen soil areas.
