摘要: 采用异位生物修复技术堆式堆制处理方法,对辽河油田原油污染土壤进行了生物修复处理研究.处理工程设4个处理料堆单元,每个处理单元长118.5cm,宽65.5cm,高12.5cm.研究结果表明,当进行处理的石油污染土壤中石油烃总量为5.22g·100g-1土时,利用黄孢原毛平革菌(Phanerochaete chrysosporium),经过55d的运行,石油烃总量去除率达54.2%.堆制处理中影响污染土壤石油烃总量生物降解的主要变化因子为污染土壤的O2和CO2含量、降解石油烃微生物的数量、污染土壤pH的变化.通过监测这些数据的变化,可直接反映该工程的处理石油污染土壤的效果.本处理工程采用定期通风措施,操作简单、运行费用低廉,为石油污染土壤生物修复实用化提供了一种简单易行的污染土壤清洁技术.

Abstract: With composting technology of off-site bioremediation,the bioremediation of soil contaminated by crude oil from Liaohe Oil Field was studied. 4 treatments units were set,each units being118.5 cm in length,65.5 cm in width,and 12.5 cm in height. The results showed that when the soil was contaminated with 5.22 g?100g-1 TPH,the degradation rate of TPHreached 54.2% after 55 days operation by Phanerochaete chrysosporium. The results also indicated that the major factors that effected the TPHbioremediation results were the content of O2 and CO2,the amounts of microorganism that degraded petroleum hydrocarbons,and the changes of pHin contaminated soil. These factors could directly reflect the effect of composting treatment technology,and be used to optimize the operation conditions of composting technology to reach the best result. The treatment engineering adopted periodical aired means,operated very simple,and costed very cheap,whtch provided a practical technology for the bioremediation of petroleum-contaminated soil.
