摘要/Abstract

摘要： 对不同类型原油污染土壤在实用规模的预制床上采用堆制技术进行生物修复.通过投加肥料、菌剂、控制水分和pH,可使微生物获得较好的生态环境.当稀油、高凝油、特稠油和稠油污染的土壤中原油总量为25.8～77.2g·kg^-1土时,经过近2个月的运行,石油总量的去除率可达38.37%～56.74%.石油中芳烃、沥青和胶质混合物是制约石油快速降解的主要因素.在处理过程中筛选出石油降解的优势菌株,其中有6株真菌、6株细菌和1株放线菌.研究结果为石油污染土壤异位生物修复技术实用化提供了理论依据.

Abstract: The bioremediation of soils contaminated by different types of petroleum were carried out with composting process in a prepared bed. By the measures of nutrient and microbiological agent addition, and moisture and pHcontrol, an ideal environment for microbes was obtained. When total petroleum hydrocarbons, which consist of thin oil, high condensation oil, special viscous oil, and viscous oil, were in the range of 25.8～77.2g·kg^-1 dry soil, the petroleum removal rate could reach 38.37～56.74% by 2 months operation. The contents of aromatic hydrocarbon, asphaltum and resin were important factors controlling the degradation of petroleum. 6 fungi, 6 bacteria and 1 actinomyces were found to be the dominant strains for petroleum degradation.The results could provide theoretical bases for remediation of soil contaminated by petroleum.
