摘　　要：利用自然堆肥和2种强化堆肥技术对大庆油田含油污泥进行生物修复处理,比较不同堆肥方式中各理化参数和总石油烃降解的变化趋势,建立最佳的堆肥体系,结果表明,3种堆肥方式均呈现有机碳含量下降而总氮含量上升趋势,2种强化堆肥可延长堆肥高温时间,堆肥结束后石油烃降解率显著高于自然堆肥,其中表面活性剂强化堆肥是最佳的处理方式,对含油污泥降解率高达88%,降解半衰期为14d。The bioremediation of oily sludge in Daqing oilfield was treated by natural compost and two Enhanced Composting Techniques.To compare the change of the physical and chemical paramnters and degradation of total petroleum hydrocarbons（TPHs）and establish optimal composting system.The results show that in the three compostingmethods,the content of organic carbon decreased and the total nitrogen content increased.The strengthened composting can prolong the high temperature time of composting and petroleum hydrocarbon degradation rate is significantlyhigher than that of natural compost.The surfactants compost is the best way to compost,the degradation rate of oilysludge is as high as 88%,and the half-life of the degradation is 14 d.
