摘　　要：在平均温度为-3.9℃的外界环境下,通过引用4株外源微生物以及补充磷酸盐和硝酸盐作为营养源,对炼厂含油污泥用生物堆肥法处理。经过120 d处理后,油泥油含量已经达标,低于GB4284-84所规定的3 000μg/g干泥,硫化物含量大幅度的降低,从28μg/g降到4μg/g。通过色谱-质谱联用分析了各组份降解前后的变化规律。结果表明,利用合适降解石油的外源微生物是必要的,可以明显的增强降解效率和缩短生物修复进程。A phosphate and a nitrate source were provided, the composting of oily sludge in refinery with the designated mixture of four excellent strains in 120 days at the averaged temperature of -3.9°C resulted in TPH (total petroleum hydrocarbon) less than 3000 μg/g dry sludge, which has met GB4284-84. And the mass fraction of sulfide reduces from 28 μg/g to 4 μg/g. The biodegradation of each chemical component was analyzed to probe the rule by the GC-MS. The result demonstrates the importance of utilizing foreign microbes which adapted to the pollutants to enhance the efficiency and productivity of bioremediation process.
