| 摘要: |
| 为考察膜组合工艺处理微污染原水的可行性,研究膜生物反应器(MBR)与膜粉末活性炭生物反应器(PAC-MBR)对低温低浊微污染引黄水库水的处理效果及膜污染状况.两者对浑浊度均能保证稳定的去除效果,去除率保持在97%以上;对有机物去除能力依次为PAC-MBR>MBR>常规处理工艺>单独的超滤膜(UF);单独的超滤膜对氨氮几乎没有截留作用,挂膜后的PAC-MBR和MBR对氨氮的去除效果比较稳定,平均去除率分别为3.39%、65.01%.跨膜压差(TMP)的对比研究表明,以PAC为生物载体形成的活性污泥相对自然形成的活性污泥有较高的生物活性、较好的过滤特性,对膜污染具有一定的延缓作用. |

| Abstract: |
| To investigate the feasibility of hybrid membrane process for treating micro-polluted water,the treatment of micro-polluted reservoir water from Huanghe river,which presented low turbidity and low temper-ature were carried out,and the submerged membrane bioreactors without(MBR)and with(PAC-MBR)pow-dered activated carbon(PAC)were evaluated for drinking water production,while the fouling mechanism of the two membrane were discussed too.Both of the MBR and PAC-MBR guaranteed the turbidity removal a-bove 97%.The ability of organic substances removal were:PAC-MBR>MBR>conventional process>ultra-filtration(UF)alone.No effect of UF alone on NH 3-N removal was observed,while PAC-MBR and MBR gave an average removal rate of 73.39%and 65.01%,respectively.By comparing the trans-membrane pres-sure(TMP)trend of two bioreactors,it could be concluded that activated sludge,with PAC as a carrier,showed higher activity and better filterability than the activated sludge naturally formed,and PAC-MBR ap-peared a slower membrane fouling. |
