摘要: 探讨中国淄博地区地下水源石油污染的微生物治理技术.从污染地分离筛选出10株除油菌,经测定单菌株的降油率在20~50%,混合菌群MZ9402的降油率可达71.4%.在含油地下水模拟反应器中,当投菌浓度保持在106个·ml-1时,混合菌群MZ9402的降油率可达53.1%.在地下水石油污染的现场治理时,MZ9402的投菌量为10L·d-1(109个·ml-1),11d后在地下水流段面形成较稳定的微生物带,降油率保持在35%左右.经初步鉴定,所投加的MZ9402菌群未发生变异.

Abstract: The microbial treatment of petroleum-contaminated groundwater was carried out in Zhipo, China. Ten strains of degradation bacteria were isolated from petroleum contaminated land. The experimental result showed that the degradation efficiency of single strain ranged from 20 to 50%; and that of mixed strains MZ9402 was 71.4%. In a simulation reactor contained with petroleum contaminated groundwater, the degradation efficiency of MZ9402 was up to 53.1% when the concentration of injected bacteria was 106 individuals·ml-1 . Field scale experiments showed that when the concentration of injected bacteria MZ9402 was 109 individuals·ml-1, a more stable microbial zone could be formed in the waterflow section after 11 days, and 35% of the petroleum could be degraded. According to the tentative identification. no mutation was occurred for the injected MZ9402 strains.
