Treatment of Chemical Synthesis-Based Pharmaceutical Wastewater with Combined ABR and MBR System
The performance of treating chemical synthesis-based pharmaceutical wastewater with combined ABR and MBR system was evaluated under different operating conditions: first, the system was conducted at a medium temperature (23℃-28℃), The average COD removal efficiency of ABR was constantly maintained at around 65％ and the total COD removal rate of the system was from 95％ to 98％. When the influent COD concentration varied from 5161 mg/L to 16740 mg/L, the final effluent COD of membrane bioreactor was 300～500 mg/L. Second, the system was conducted at low temperature (11℃-17℃ ). The average COD removal efficiency of ABR was only 30％-50％. MBR process supplied a large contribution to organic removal, the effluent COD stabilized at about 600mg/L. The effluent NH3-N concentration of ABR was higher than that in the influent obviously if it was fed raw wastewater, but the MBR which was fed the effluent from ABR had a good effect on NH3-N removal.
