摘要
活性污泥性能是倒置A2/O-动态膜生物反应器工艺稳定运行的关键因素,研究了活性污泥培养和反应器启动阶段,考察了活性污泥性能及对污染物的去除效果。结果表明,好氧池活性污泥MLSS由3 460 mg/L增加至6 100 mg/L,粒径d50由27.8μm增至59.8μm,活性污泥培养阶段,COD、NH3-N和TP去除率分别达到85.7%,97%,87%;反应器启动阶段,COD、NH3-N和TP去除率分别达到91.9%,99%,96.5%。
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.
