摘要
选取某石油类污染地区为对象,研究地下水阴阳离子浓度不同时凹凸棒石净化石油烃污染地下水的效率,为下一步的PRB修复工作做准备。结论表明:凹凸棒石经过热处理改性后,可提高去除污染地下水中石油烃的能力,凹凸棒石的最佳热处理温度为130℃。除Na+对凹凸棒石净化石油烃去除率在低浓度有抑制作用外,其他离子均在低浓度时对去除率有促进作用,在高浓度时对去除率有抑制作用。
An oil contaminated area was chosen to find the removal efficiency under the condition of different cation-anion concentration in groundwater which was the preparation for the next PRB repair work.Conclusions indicate that the detoxification ability of petroleum hydrocarbons in groundwater can be increased after the modification of attapulgite through heat treatment.The best heat treatment temperature is 130 ℃.All of ions except Na＋can promote the removal rate at low concentration and restrain it at high concentration.
