| 摘 要： | 在一体式MBR系统中投加少量的粉末活性炭,运行效果良好,并且可以很好地降低膜污染。粉末活性炭在形成生物活性炭后,对难降解有机物具有很好的降解能力;NH4^ -N的去除率得到进一步提高,NO3^-的含量升高;但反硝化作用不明显,致使总氮去除率不高;生物活性炭很好地吸附并降解了易引起膜污染的有机物,改变了污泥的性质,对膜组件起到了很好的保护作用。

| Abstract: | The running of MBR system with PAC(1g/L) was studied.The PAC-MBR system gave a higher removal of NH_4~ -N,but the removal of TN was lower with a high quantity of NO_3~-.And it could degrade some non-biodegradable organic compounds such as extra-cellular polymeric substances(EPS) and soluble microbial products(SMP),which were major fouling causing substances in the membrane coupled activated sludge system.At the same time,PAC improved the activated sludge's characterizations such as compressibility.These could help to reduce the fouling of membrane. |
