摘  要：
含油污泥主要来源于原油的勘探、开采和运输过程,在回收石油过程中由于采用加热后助剂提取方法,使油泥中大量微生物失活,为生物修复处理带来新的困难。针对这种含油污泥,采取投加固体菌剂的方法增加微生物种群,通过投加客土、肥料、水分及改变pH,调控微生物的营养和生存环境。利用正交实验L934方法选择了较理想的含油污泥生物修复条件。实验结果表明,处理含油污泥时投加客土是影响处理效果的重要因素,较理想的处理条件为:在自然温度条件下,客土投加量10%￣20%、肥料5%、菌剂5%(湿重)、水分30%(烘干基)和pH7.0。当TPH初始浓度为20.6￣22.3g·kg-1时,60d后其去除率>49%。在实验过程中,堆料的O2含量的变化能够反映出生物降解过程中微生物的活性及总石油烃(TPH)的处理效果变化趋势。

摘  要：
Mud containing oil mainly resulted from the processes of exploration, extraction and transportation of crude oil, and it is intractable for its treatment in the broad oil fields, especially that obtained from the treatment of heating and using solvent that decreased the activities of microbes and therefore more difficult for bioremediation. The influences of applying fertilizer, changing the amount of soil dressing, moisture and pH value on the bioremediation effect of mud containing oil were studied. The experiment of orthogonal design L934 proved that application of soil dressing was an important factor affecting treatment efficiency. Under natural temperatures, the optimized parameters were as follows: amount of soil dressing 20%, fertilizer 5 %~10%, solid microbial materials 5%, moisture 30% and pH 7. When the original TPH concentrations were in the range of 20.6~22.3g·kg-1, its removal rate was more than 49%. During the composting processes, the contents of O2 in composting piles could reflect the activity of microbe and the treatment efficiency of total petroleum hydrocarbon.
