摘要

不同乙醇浓度的汽油组分对含水层介质渗透率有显著影响。由于污染物浓度的不同会改变含水层介质的环境，造成介质孔隙空间的堵塞，影响含水层中污染物的导水能力和生物修复能力。通过四组砂柱试验，研究了污染多孔介质渗透率的环境影响因素。结果表明:影响渗透率的环境因素有溶解氧、温度、PH值和电导率，溶解氧是影响渗透率的主要因素;

Environmental Influencing Factors of Permeability on Contaminative Aquifer Medium by Ethanol Blended Gasoline

Different ethanol concentration of gasoline components have a significant influence on the permeability of aquifer medium. Because the different of pollutant concentrations will change the environment of aquifer medium, bring on jamming the pore space of medium and influence the hydraulic conductivity and bioremediation of pollutants in aquifer. This study focuses the environmental influencing factors of permeability on contaminated porous medium via four sand columns experiments. Results show that environmental influencing factors of permeability are dissolved oxygen, temperature, PH value and conductivity, and the dissolved oxygen is the main influencing factor of permeability.
