摘　　要：小试和中试研究结果表明 :粉末活性炭在膜生物反应器系统中具有改善泥水混合液的性质和膜表面泥饼层结构的作用 ,从而减小了膜的过滤阻力 ,减缓了膜通量的下降。向膜生物反应器内投加粉末活性炭是提高和维持膜通量的有效途径 。The laboratory scale and pilot scale tests on MBR showed that dosing PAC could improve characteristics of mixed liquor and the structure of cake layer on the surface of membrane, and therefore filtration resistance was reduced and flux in decline was reterded. The experimental results showed that dosing PAC was an effective way to incease membrane flux and decrease the operating cost of MBR.
