| 中文摘要 |
| 通过小型泥浆反应器的运行,确定了生物泥浆法修复多环芳烃污染土壤的温度、水土比和通气量参数.采用2:1的水土比,控制温度、通气量分别为20℃～25℃,60L/h可以达到较好的修复效果.用从污染土壤中分离出的真菌在纯培养条件下对多环芳烃进行降解,经34d的培养,镰刀菌对芘和苯并蒽的降解率为90%和33.3%,毛霉可以分别降解81.5%和49.2%,青霉可以分别降解52%和46%. |
| 英文摘要 |
| Through the operation of the pilot scale slurry reactor, the operational parameters of bioslurry remediation for soil contaminated with polycyclic aromatic hydrocarbons(PAHs), including temperature, ratio of water to soil, aeration flux, were determined. As the operational condition was that the ratio of water to soil was 2:1, the temperature was 20℃～25℃ and aeration flux was 60L/h, a good result of the remediation could be achieved. With the fungi isolated from contaminated soil as pure culture to degrade PAHs, after 34 days incubation, 90% of pyrene and 33.3% of benz[a]anthracene were degraded by Fusarium 81.5% of pyrene and 49.2% of benz[a]anthracene were degraded by Mucor, 52% of pyrene and of 46% of benz[a]anthracene were degraded by Penicillium. |
