摘要： 以分离得到的两株高效石油降解菌为试验菌种，通过对电场作用方式、电极材料及电场作用强度的筛选及正交试验研究，确定电场强化微生物修复油污土壤的最佳条件。结果表明，对于菌株W\|1，当电场作用方式为平行网格式，电极材料为石墨电极，电场作用强度为150 V·m-1时，电场强化微生物修复油污效果最佳；对于菌株W\|2，当电极材料为石墨，电场作用方式为平行板式，电场作用强度为200 V·m-1时，电场强化修复效果最佳。

Abstract: In the present study， two oil degradation bacteria W\|1， W\|2 were isolated and used to optimize reaction conditions by single\|factor and orthogonal experiments on electric field， electrode materials and electric field strength. It was shown that as for W\|1， when the electric field was parallel grid， electrode material was graphite electrode， and the electric field strength was 150 V·m-1， the oil degradation rate was the highest. As for W\|2， when the electrode material was graphite， electric field was parallel\|plate， and electric field strength was 200 V·m-1， the oil degrading rate was the highest.
