【摘要】 从油田污水中分离到一组可高效降解石油烃的混合菌群F6。室内模拟实验证明,该菌群适于油田含油污水的净化处理。采用粒状活性炭为载体的生物流化床系统处理辽河油田“兴一联”（辽河油田兴隆台第一联合站）污水,可使含油量由45mg/L降至4.1mg/L、CODcr由 470mg/L降至42mg/L。处理后的石油污水达到国家石油污水一级排放标准。更多还原

【Abstract】 A mixed bacteria culture F6 isolated from oil field wastewater can degrade petroleum hydrocarbons efficiently. The bacteria were suitable to treat oil-polluted wastewater of oil field. Simulated result treating oil-polluted wastewater in laboratory showed that after "XingyiLian" wastewater of Liaohe Oil Field was treated by fluidized-bed bioreactor system with the vehicle of activated carbon , the amount of oil and CODcr of the flow out water were decreased from 45mg/L to 4. 1mg/L and 470mg/L to 42mg/L separately , according with first class standards of Chinese Wastewater Discharge Regulation.更多还原
