Process Fundamentals and Field Demonstration of Wheat Straw Enhanced Salt Leaching of Petroleum Contaminated Farmland
麦秸强化石油烃污染耕地水浸洗盐过程及场地试验

A new remediation method for petroleum-salt contaminated soil was proposed,in which wheat straw was applied to enhance salt leaching and meanwhile block salt upmovement along the soil capillary.It was shown that the existence of petroleum increased the surface hydrophobicity of soil and thus hindered the leaching process once the oil content was above 1.5%(mass fraction).The application of 5% (mass fraction) wheat straw into the soil increased the efficiency of salt leaching from 3% to 25%.The effectiveness...
