| Abstract: | Activated sludge performance is the key to the stable operation of reverse A2 / O-dynamic mem-brane bioreactor（DMBR）. The performance of activated sludge and the removal effiency of pollutants are investigated in the sludge cultivation and inversed A2 / O-DMBR startup process. The results show that MLSS and particle size of sludge（d50 ）in aerobic pond increased from 3 460 mg / L to 6 100 mg / L,from 27. 8 μm to 59. 8 μm,respectively. The average removal rate of COD、NH3-N and TP reached 85. 7% , 97% and 87% in activated sludge cultivation process,and the average removal rate of COD,NH3-N and TP reached 91. 9% ,99% and 96. 5% in the reactor startup process. |
