摘要
电动力耦合技术通过在微生物处理落地油泥基础上施加一定的电场,以增加生物活性,通过耦合作用提高微生物对油污土壤中石油烃的降解速率。结合中试装置及高效复合降解菌种,在安塞油田首次开展了电动力耦合微生物降解落地油泥现场试验,结果表明通过在生物修复基础上施加电场,可将降油率提高15%以上,同时定期翻堆会进一步提高修复效果,添加表面活性剂处理,在电动力-微生物联合修复基础上将降油率再提高约5%。
The electrodynamic coupling technology is adding a certain electric field on the basis of microbial treatment of ground oil sludge to increase the biological activity.By the microbes through coupling,the degradation rate of the petroleum hydrocarbons in the oily soil was improved.Combining with the pilot plant and high-efficiency composite degradation bacteria,the electro-dynamic coupling microbial degradation of ground oil sludge field test was carried out in Ansai Oilfield for the first time.Results showed that by applying an electric field on the basis of bioremediation,the oil reduction rate can be increased above 15%.Meanwhile,regular stacking will further improve the repair effect.Adding surfactant treatment will increase the oil reduction rate by about 5%on the basis of electrodynamic-microbial joint repair.
