中文摘要：

利用人工配制的2种不同浓度（1000和100μg·kg^-1硝基苯污染底泥,研究了4℃和20℃ 2种温度条件下硝基苯的自然衰减和生物强化降解情况.结果表明,2种浓度的硝基苯在4℃时有氧、缺氧条件下均无降解,20℃时有氧和缺氧条件下均有明显的降解;添加筛选出的混合降解菌可快速降解处于泥浆状的硝基苯.因而,对于受到硝基苯污染的底泥修复可充分考虑其自然衰减能力,降低修复成本.

英文摘要：

Temperature is key factor for natural attenuation of nitrobenzene. The present study investigated the nitrobenzene of natural attenuation and nitrobenzene of bio-argumentation at 4℃ and 20℃. The results showed that two kinds concentration of nitrobenzene （ 1000 and 100μg. kg^-1 ） were not degraded under aerobic and anoxic condition at 4℃ , however they were significantly degraded at 20℃. Applying the screened nitrobenzene degrading microorganisms quickly degraded the high concentration of nitrobenzene （ 1000μg· kg^- 1 ）. Therefore, remediation of mud with nitrobenzene should fully consider ability of natural attenuation.
