生物活性碳纤维处理苯酚模拟废水的研究

Treatment of Phenol Synthetic Water Using New Water Treatment Technique of Biological Activated Carbon Fiber

实验以预处理和改性的活性碳纤维(AC F)为载体,经菌种筛选、驯化和生物循环挂膜,形成生物活性碳纤维(BAC F),然后将苯酚模拟废水通过BACF柱,检测了BACF去除苯酚模拟废水的性能。实验结果表明,在水样温度为1 6～20℃,pH为6.5左右,碳床接触时间为30 min时,水样流速为4.2 ml/mi n,BACF对苯酚模拟废水的平均去除率高达为97.5%,表明BACF技术对苯酚废水有优异的处理效果,并且出水水质稳定,处理量大。因此作为一种新型的苯酚废水处理技术,BACF技术将具有广阔的应用前景。

Biological Activated Carbon Fiber （BACF）, as new technique of water treatment, was investigated for organics removal from water. Microbes were incubated on ACF by means of flow circulation to form BACF. The resultant BACF bed was used to remove phenol from phenol waste water. After treatment, the average removal efficiency attained as high as 97.5%. It suggests that BACF as an advanced technique has great application potential for phenol synthetic water water treatment.
