| 摘 要： | 通过性能测定观察到,菌株Candidasp.对苯酚具有较强的降解能力,因此选取来作为生物强化试验的模式菌株.通过不同接种量、不同苯酚初始浓度的比较实验,发现随着菌体加入量的增加,活性污泥系统获得的生物强化效果逐渐增强,随着初始底物浓度的增加,活性污泥系统的生物强化效果逐渐减弱,同时通过20d的长期实验发现,强化效果没有随时间减弱,而且比单独活性污泥系统经过20d驯化所得的降解能力高60%.图4参7

| Abstract: | Candida sp. was tested and found with strong degrading capacity of phenol, and was selected as model microbe for studying bioaugmentation of the activated sludge system. The experiments with different amounts of inocula and initial concentrations of phenol indicated that the bioaugmentation effect of the activated sludge system was gradually enhanced with increasing of inocula, but weakened with increasing of initial concentration. The bioaugmentation effect remained the same in a long period of 20 days, and the degrading capacity of the activated sludge system was 60% higher than that of single active sludge after domestication for 20 days.
