研究从采出水中分离3株TPHs及SS优势降解菌株，经鉴定分别为枯草芽孢杆菌、多食鞘氨醇杆菌和荧光假单胞菌。通过降解特性研究得出复合菌群处理采出水的最佳曝气时间为6 h ，最适温度35℃，最适pH为7．5。复合菌群处理的采出水，出水水质稳定，其中TPHs去除率维持在95％左右，SS去除率维持在90％左右，出水已不具有腐蚀性，基本达到了油田采出水回注或排放的行业和国家标准。

연구종채출수중분리3주TPHs급SS우세강해균주，경감정분별위고초아포간균、다식초안순간균화형광가단포균。통과강해특성연구득출복합균군처리채출수적최가폭기시간위6 h ，최괄온도35℃，최괄pH위7．5。복합균군처리적채출수，출수수질은정，기중TPHs거제솔유지재95％좌우，SS거제솔유지재90％좌우，출수이불구유부식성，기본체도료유전채출수회주혹배방적행업화국가표준。
Three dominant strains of TPHs and SS are separated from oilfield produced water and they are Bacillus subtilis , Sphingobacterium multivorum and Pseudomonas fluorescens .Characteristics of compound bacteria are studied by indoor ex-periment and it is found that the optimal aeration processing time is 6 h ,optimal degradation temperature is 35 ℃ and opti-mal pH is 7 .5 .After treatment by the compound bacteria ,the effluent water is stable ,TPHs removal rate maintains around 95% ,SS removal rate about 90% and the effluent has no causticity ,which basically reaches the industrial or national stan-dard of water reinjection or discharge of oilfield produced water .
