摘　　要：通过室内模拟实验,探讨了在非水相硝基苯污染含水层的条件下,其在含水层中的迁移及释放规律。迁移规律表明,非水相硝基苯并非在含水层中直接进行垂向迁移,而是一方面在自身重力作用下向含水层下部迁移,另一方面在地下水流的作用下随地下水同向运移,整体表现为随地下水流的侧向运移,并最终迁移至含水层底部。释放规律表明,非水相硝基苯在含水层迁移的过程中会向地下水大量释放,释放出的硝基苯在水流的作用下随地下水同向运移,污染源及迁移至含水层底部的非水相硝基苯均存在再次释放。A simulated tank experiment was carried out to investigate the migration and releasing rules of non-aqueous nitrobenzene in aquifer.The migration rules indicated that non-aqueous nitrobenzene was not migrating directly in the vertical,on one hand,non-aqueous nitrobenzene migrated to the lower and finally to the bottom of the aquifer,on the other hand,it migrated with the groundwater,in a whole,it was the lateral migration in the groundwater.The releasing rules showed that non-aqueous nitrobenzene would release much nitrobenzene to the groundwater while migrating in aquifer.the released nitrobenzene flowed with the groundwater in the same way,and the non-aqueous nitrobenzene both in the pollution area and in the bottom of the aquifer would release again.
