摘　　要：文章对从农药厂、三化厂和焦化厂废水中分离的细菌NYC-1A、SHC-1B和JHC-1C,通过逐步提高苯酚浓度对它们加以驯化,采用模拟SBR工艺对驯化前后三株细菌对含有苯酚的培养液的处理效率进行了比较研究。结果表明:细菌湿重为1 g/L,苯酚培养液经处理16 h后,JHC-1C的苯酚降解率最高为89.59%;其次为NYC-1A,降解率为77.88%;SHC-1B的降解率最低,降解率为53.31%。驯化后三株细菌处理苯酚培养液3 h,NYC-1A降解率最高为76.37%,SHC-1B的降解率为69.29%,JHC-1C的降解率为45.66%。通过本文研究,表明苯酚降解菌经驯化后可有效提高降解苯酚的效率。The three bacterial strains designated NYC - 1A, SHC - 1B and JHC - 1C were isolated from pesticide factory, the third chemical factory and Coking plant, respectively. Phenol - degrading rate was Comparised before and after acclimating of phenol by simulating SBR process. The result indicated Phenol -degrading rate of JHC - 1C, NYC - 1A and SHC -1B were 89. 59%, 77.88% and 53.31% after 16h treatment, respectively before acclimating of phenol. Phenol - degrading rate of three bacterial strains were increased after acclimating, phenol - degrading rate of JHC - 1C, NYC - 1A and SHC - 1B were 76. 37%, 69. 29% and 45. 66% after 3h treatment, respectively. The result showed the phenol -degrading rate can be improved by acclimating.
