| 摘 要： | 从3种污泥中驯化筛选出10种菌株,研究了各菌株对油制气废水不同污染指标的处理能力差别,以及各菌株对废水中芳烃化合物的降解能力.结果表明,各菌株可在初始阶段提高废水的BOD值,在高低废水浓度条件的降解能力基本一致;酚的去除率可达93.9%,但对废水中氨氮的去除率小于27.3%;实验采用的3种菌株对废水中的芳烃化合物都能降解,但其对芳环数≤3的芳烃化合物的降解能力强于对芳环数为4~6的芳烃化合物的降解能力.图4表2参10

| Abstract: | 10 acclimated bacterial strains isolated from 3 kinds of activated sludge were used to biodegrade different pollutants in MGO wastewater produced in the manufacturing process of gas with heavy oil. The results indicated that all the bacterial strains could increase BOD value at the beginning and their pollutant-biodegrading abilities were nearly the same at different concentrations. The removal rate of phenolic compounds reached 93.9%, but that of NH 4-N was less than 27.3%. The 3 selected bacterial strains could biodegrade nearly all the aromatic compounds in wastewater, but the ability to degrade aromatic compounds with less than 3 aromatic rings was much stronger than that with 4~6 aromatic rings.
