| 摘 要： | 用一体浸没式膜生物反应器(SMBR)不同特性膜处理上海市城市内河道水,结果表明,SMBR对氨氮含量较高的富营养化河水,氨氮的去除率在90%以上,但对COD的平均去除率仅为50%.比较两种膜的运行性能,亲水性膜在运行通量和通量恢复能力上,均比疏水性膜优越.两种膜的出水水质几乎没有差异.

| Abstract: | A bench-scale experiment of SMBR(submerged membrane bioreactor)using different characteristic membranes was conducted to treat eutrophic river water of city with high concentration of NH _4-N in Shanghai. The results show that NH _4-N removal efficiency was over 90%,but the average removal efficiency of COD_ cr was only 50%. The comparison of membranes performance indicates that hydrophilic membrane was better than hydrophobic membrane concerning flux and backwashing. There were no apparent differences in effluent quality from the two different characteristic membranes. |
