Mathematical Modeling of Operation Process of Dynamic Membrane Bioreactor

Ji-Zhi Lin, Qian Zhang, Jun-Ming Hong
Abstract—The effects of different influent C/N ratios on the removal efficiencies of COD, total nitrogen, ammonia, nitrite and nitrate were investigated in a dynamic membrane bioreactor (DMBR), which was used to treat synthetic domestic wastewater. A simplified activated sludge model(SASM) was proposed, which based on the activated sludge model No.1(ASM1). The results showed the effluent concentrations of COD were less than 50 mg·L-1 in the DMBR. The removal efficiencies of COD were more than 85% in the different C/N ratios. The effluent concentrations of total nitrogen and ammonia were gradually increased as the ratios of C/N decreased. When the ratio of C/N was more than 6.75, the removal efficiencies of total nitrogen and ammonia were more than 50% and 60%, respectively. The SASM was feasible for DMBR simulation and the simulated values of nitrite and nitrate almost equal to the experiment values.

Index Terms—Dynamic membrane bioreactor (DMBR), simplified of activated sludge model (SASM), C/N ratio.
