| Abstract: | The ceramic and hollow fiber ultrafiltration membrane bioreactors were separately applied for advanced treatment of the printed circuit board （PCB） wastewater. The results show that ,when concentration of dissolved oxygen （DO） is 4.0-8.0 mg/L, hydrodynamic retention time （HRT） is 5 h, MLSS is 6500 mg/L, COD and ammonia nitrogen are 191.2-270.4 mg/L and 30.0-50.0 mg/L respectively, COD and ammonia nitrogen in the effluent from membrane bioreactors are less 99.2 mg/L and 0.759 mg/L respectively;The quality of treated wastewater can meet the first grade of lntegrated Wastewater Discharge Standard GB8978-1996. |
