摘  要：
主要研究草炭土在修复地下水石油烃过程中水化学因子的变化规律,实验选取Fe3+、Mn2+、SO2-4、Ca2+、Mg2+、NH+4、HPO2-4、NO-3离子进行相关研究,实验结果表明草炭土对于水化学因子有一定的改变作用,对Ca2+的去除率稍低在58.77%~66.50%之间,Mn2+、NH+4、Mg2+、NO-3、的去除率均大于80%,而SO2-4、Fe3+、HPO2-4几乎被全部去除,去除率均大于97%。SO2-4、NH+4、NO-3对草炭土吸附石油烃具有促进作用,Ca2+对草炭土吸附石油烃具有抑制作用,较低浓度的HPO2-4不利于草炭土去除石油烃,Fe3+、Mn2+、Mg2+对草炭土吸附石油烃影响不明显,8种离子对草炭土吸附石油烃的影响随浓度改变。

摘  要：
This paper mainly studies the variation law of hydro-chemical factors during repair process of the peat soil for petroleum hydrocarbons in groundwater.In the experiments,the elements of Fe3+,Mn2+,SO2-4,Ca2+,Mg2+,NH+4,HPO2-4,and NO-3 are chosen to conduct the research.The results show that the peat soil has a certain effect on the changes of water chemical factors;the removal rate of Ca2+is between 58.77%to 66.50%,that of Mn2+,NH+4,Mg2+,NO-3 is greater than 80%,while Fe3+,SO2-4,HPO2-4 are almost completely removed and the removal rates are more than 97%.The SO2-4,NH+4,and NO-3 have promotion effect on the adsorption of the peat soil for petroleum hydrocarbons,while Ca2+has the inhibition effect on the adsorption of the peat soil for petroleum hydrocarbons;HPO2-4 with lower concentration is not conducive for the removal of petroleum hydrocarbons,the Mn2+,Mg2+have no significant effects on it.The effects of the eight kinds of ions on the adsorption of the peat soil for petroleum hydrocarbons change with the concentration.
