Abstract
Three dominant bacteria of A-1, B-1 and C-1 for phenol degradation were screened by domestication. Then study on the treatment efficiency of phenol by the three dominant bacteria was carried out under different concentration of phenol wastewater. The results showed that phenol removal efficiency decreased as the phenol concentration increasing. The phenol removal efficiency rates achieved 46.74%, 51.43% and 23.08% by A-1, B-1 and C-1 in24h when phenol concentration was 50 mg•L-1, and 70.22%,75.19% and 20.43% when concentration was 100 mg•L-1. The best degradation efficiency achieved by the bacterium B-1. Lastly, effect of reaction time, pH and temperature on phenol degradation with B-1 was studied. The result showed when reaction time was 48h, pH was 7, temperature was 30¡æ, phenol and COD removal efficiency achieved about 50% and 30%, respectively.
