The Experiment Research of BAF in Treatment on Pharmaceutical Wastewater

Abstract:

This research has discussed the biofilm formation on the treatment of pharmaceutical wastewater in BAF. The removal rate of COD and NH3-N and law of the performance on the temperature and height of fillers are studied here. The results show that the BAF can still maintain a higher COD removal rate in the 13°C-25°C, the average removal rate reaches 86.9%. The denitrification is impacted by low temperature that the average removal rate of 74.7%. Experiment shows that, from 0cm to 65cm part, the removal rate of COD reachs 86.3%. The good performance of NH3-N removal rate mainly concentrates in the height of 35cm ~ 95cm.
