Microbe-lift复合菌剂处理油田废水的性能研究

Study on Microbe-lift Capable of Treating High-salt oil Waste Water

探索美国生态实验室Microbe-lift复合菌剂处理高矿化度含油废水的可行性及处理性能。研究结果表明:Microbe-lift菌在pH值5.5~9.5和温度20~40℃的范围内能有效降低废水COD值;在pH值为7.5、温度30℃,接菌量15%时,初始COD值为688 mg·L^(-1)的废水经120 h处理后,COD去除率可达到63.15%。

In the paper,we explore the possibility and efficiency of treatmenting oilfield wastewater by Microbe-Lift inoculums from American ecological laboratory.The result indicated that Microbe-Lift was capable of surviving under the condition of pH value 5.5~9.5 and temperature 20~40℃.The COD removal efficiency achieved to 63.15% from the initial concentration of 688 mg·L^-1 when the pH,temperature,inoculum volume were separately 7.5,30℃ and15%.
