Organebentonites have been widely used to treat with polluted water in environmental applications. We use natural soil instead of Organobentonites to sorb pollutants in waste water, remove organic Matters of landfill leachate and control infiltration of landfill leachate.,The soil was modified by octadecyl trimethyl ammonium chloride. This modified soil had on adsorbing-pollutants in polluted water, and landfill leachate, but it was equivalent to natural soil on antiseepage. So it was not applicable in antiseepage project and could be promote use in the sewage treatment. promote use in the Sewage treatment.
