石油污染对土壤水理性质的影响

【目的】给石油污染土壤水分调节利用以及修复治理提供参考。【方法】系统归纳总结了现有石油污染对土壤水理性质的影响研究成果,同时对污染引起土壤水理性质产生变化的机理进行探讨。【结果】石油污染对生态环境产生了大量负面影响,使生态环境承载了巨大的污染负荷。当石油污染物进入土壤后,会影响了土壤孔隙结构,改变土壤颗粒表面润湿性,同时石油中含有的挥发、半挥发性有机污染物会对土壤水分运移产生阻滞效应,从而会对土壤的持水能力、毛管水运动特征、土壤渗透性能等多方面产生影响。【结论】为准确揭示石油污对土壤水理性质产生影响的作用机理,仍需进一步从微细观上深入开展相关研究。

Effects of Oil Pollution on Soil Water Physical Characteristic

【Objective】In order to provide a basis for the regulation and utilization of oil-contaminated soil moisture, and provide reference for the remediation of oil contaminated soil,【Method】this study starts from the aspects of soil water characteristics, systematically summarized the existing research results, and discussed the mechanism of soil water changes caused by pollution.【Result】Oil pollution had a large negative impact on the ecological environment, causing the ecological environment to carry a huge pollution load. When oil contaminants entered the soil, it would affect the pore structure of the soil and change the surface wettability of the soil particles.At the same time, volatile and semi-volatile organic pollutants contained in oil would have a retarding effect on soil water transport, which would affect soil water holding capacity, capillary water movement characteristics and soil permeability.【Conclusion】In order to accurately reveal the mechanism of the impact of oil pollution on soil water physical characteristics, it is still necessary to further carry out relevant research from a microscopic view.
