| Abstract: | A high efficient novel process of biological treatmenting wastewater with phenols was proposed in this paper, It was researched in a new kind of three-phase jet bubble loop bioreactor with combining the immobilization technology. The influence factors were studied on the degradation of phenols wastewater. Coal powder was chosen as the biological carrier. The optimized continuous degradation conditions were obtained: gas rate=0.017m·s－1, operation temperature=28℃, pH≈7.5, wastewater input flux=20.0L·h－1, the phenol concentration of feed wastewater was 800 mg·L－1, and that of outlet water was lowered to 0.5 mg·L－1. The kinetic equation of phenol waste degradation was experimentally obtained as follows:－dSedt＝7.194XSe0.521＋Se (mg·L－1·min－1） |
