摘　　要：以黑龙江省佳木斯市傍河地下水源地为主要模拟对象,进行了硝基苯迁移转化的室内模拟实验。结果表明:吸附与生物降解作用是影响硝基苯在含水层中迁移转化的主要因素。淤泥介质对硝基苯的除去能力较高,砂砾介质对硝基苯的除去能力相对较弱。实验过程中,从进水口至出水口的各取样点依次出现硝基苯浓度峰值,并且随着硝基苯迁移路径的延长其浓度峰值相应变小。硝基苯的浓度峰值在含水介质中的持续时间并不很长,但由于硝基苯解吸附作用的存在,在此后相当长的一段时间里都存在较为明显的拖尾现象。Based on indoors experimental research, we discuss the spatial-temporal distribution rules of nitmbenzene transformation and migration in groundwater, under the condition of groundwater recharged by river. The experimental result indicated that adsorption and biodegradation actions are the main effecting factors in this study. The removal capability of nitrobenzene transportation in silt medium is better than that in sand medium. In addition, the peak value of nitrobenzene concentration has appeared in turn and decreased along with its migration path. The duration of peak value of the concentration is not too long, but tailing phenomenon has occurred obviously in a quite long time since nitrobenzene concentration has drawn down to a certain degree according to its desorption.
