摘要：

The degradation rate of phenol-degrading biofilm was studied. The biofilm of the biofilm was a kind of phenol-degrading bacteria. The bacteria was separated from coal chemical industry wastewater. The carbon source adopted four kinds of phenols, including phenol, methyl phenol, 2-methyl phenol and resorcinol. Stenotrophomonas maltophilia K279a was gained. Twelve ratio of artificial phenol mixture was designed. The degradation rate of the twelve groups was all 99.9% in 16 h. The degradation rate from high to low was phenol, resorcinol, methyl phenol, 2-methyl phenol. Phenol improved the degradation of the other phenols. The coal chemical wastewater contained 980 mg/L COD and 805 mg/L phenol. The degradation rate of COD and phenol was 70% and 77%, respectively. The domesticated biofilm (D) and the biofilm without domestication (WD) respectively used 45 h and 56 h. The results showed that the biofilm can be applied to the aerobic treatment process with high proportion of total phenol.
