| 英文摘要 | 使用A2O-Mbr工艺处理人工合成的污水,并考察了该工艺对污水中COd、nH4+-n、总氮和PO43--P的去除效果,同时也研究了污泥的形态及变化。结果显示,该系统对COd、nH4+-n、总氮和PO43--P的去除率分别达到95%、98%、68%和70%左右,出水中nO2--n和nO3--n含量平均分别为0.4、4 Mg/l。显微镜的观察结果显示,活性污泥部分已经呈现颗粒化状态,且污泥中含有大量细菌和原生动物等微生物。研究揭示出使用A2O-Mbr工艺处理污水,出水水质比较稳定,运行状态良好。; The anaerobic-anoxic-oxic and membrane bioreactor(A2O-MBR) system was used to treat the synthetic wastewater.Water quality and sludge morphology was also investigated in the system.The results showed that the removal efficiency of COD,NH4 +-N,TN,and PO4 3--P were 95%,98%,68%,and 70%,respectively.In addition,the average concentrations of NO2--N and NO3--N in effluent were correspondingly 0.4 and 4 mg/L.Microscopy images revealed granular sludge was gradually formed from activated sludge,and a lot of microorganisms such as bacteria and protozoa lived in the sludge.The study demonstrates that A2O-MBR process can be successfully operated,and the water quality of effluent is stable.; 国家973计划前期研究专项(2010CB434802); 宁波市重大科技计划项目(2012C5011); 厦门市科技计划项目(3502Z20102017;3502Z20120012) |
