Study on Removal of Nitrogen and Phosphorus by the Integrated Intermittent-aeration Membrane Biological Reactor
Pollutants removal efficiency of the Integrated Intermittent-aeration Membrane Biological Reactor (MIBR) was investigated in this paper. And four different working conditions were researched by the laboratory-scale experiment. The results showed that the working condition III in which the periods of aeration and agitation are 2h and 2h was considered optimal for under this condition the pollutants removal efficiency of MIBR were better. Under the condition of the optimal working condition, the concentrations of COD, TN, NH4 +-N and TP in the effluent of MIBR were 12.55-40.92 mg/L, 3.66-10.10 mg/L, 0.50-6.89 mg/L and 0.18-0.98 mg/L respectively. It indicated that effluent quality of MIBR could meet the standard of the reused water quality criterion (CJ/48-1999).
