摘　　要：通过室内槽子模拟地下环境,用化学法和生物法相结合的方法,对已污染的地下水进行原位修复,污染水中硝基苯为300mg·L-1,苯胺为82.67mg·L-1。结果表明,利用零价铁还原以及微生物降解作用对被硝基苯和苯胺污染的地下水进行修复,10d后体系运行稳定,对硝基苯和苯胺的去除率分别达到了99.4%和99%,运行效果良好,为以后示范工程原位修复高浓度硝基苯地下水提供了依据。This paper simulated the surroundings of the underground where the groundwater was polluted by nitrobenzene （300 mg·L^-1） and aniline （82.67 mg·L^-1）in the trough in lab. The results indicated that nitrobenzene could be transformed into aniline by the deoxidization of the zero valent iron, and aniline would be degraded by microbe. Together with the chemical and microbial methods, the system was stable after operating 10 days, and the nitrobenzene and aniline could be well degraded, the removal rates being up to 99.4% and 99%. These results can provide some basis for the demonstrational project of nitrobenzene in-situ remediation at high concentrations.
