摘要
Microorganisms from activated sludge were immobilized by attachment to microporous plastic sheets [MPS(TM)]. Biodegradation of phenol was accomplished by pumping a phenol solution through a reactor containing microorganisms attached to the MPS(TM) sheet. Biodegradation was the primary removal mechanism, with only 5% removal by abiotic means. Experiments were conducted in batch recirculation flow and continuous flow configurations. In batch mode biodegradation rates showed a strong dependency on recirculation flow rates. In continuous mode, a residence time of 1.4 hours was needed for 50% conversion at a steady state. Consumption of phenol and dissolved oxygen showed parallel trends throughout the experiments. The polymeric membrane developed is biocompatible since the attached microorganisms were active for over 6 weeks without any toxic or harmful effects. The spiral reactor configuration developed in the study is shown to be a better design for using membranes in both laboratory and industrial scale bioreactors.
