摘要: Abstract: A spiral packed-bed bioreactor inoculated with microorganisms obtained from activated sludge was used to conduct a feasibility study for phenol removal. The reactor was operated continuously at various phenol loadings ranging from 53 to 201.4 g m(-3) h(-1), and at different hydraulic retention times (HRT) in the range of 20-180 min to estimate the performance of the device. The results indicated that phenol removal efficiency ranging from 82.9 to 100% can be reached when the reactor is operated at an HRT of 1 h and a phenol loading of less than 111.9 g m(-3) h(-1). At an influent phenol concentration of 201.4 g m(-3), the removal efficiency increased from 18.6 to 76.9% with an increase in the HRT (20-120 min). For treatment of phenol in the reactor, the maximum biodegradation rate (V (m)) was 1.82 mg l(-1) min(-1); the half-saturation constant (K (s)), 34.95 mg l(-1).
