According to the filtration characteristics of sludge, a comparison between a membrane bioreactor (MBR) and a conventional activated sludge process(CAS) was carried out under similar conditions. Experiment results show that the filtration resistance in MBR was 2 to approximately 3 times of that in CAS. The contribution of supernatant resistance to filtration resistance was about 90% both in CAS and in MBR. The test on resistance distribution showed the cake resistance made up 87.30% and 94.18% of total resistance in CAS and MBR, respectively.
根据污泥的过滤特性，在相似条件下对膜生物反应器（MBR）和传统活性污泥法（CAS）进行了比较。实验结果表明，MBR中的过滤阻力是CAS中的2至约3倍。上清液阻力对过滤阻力的贡献在CAS和MBR中均约为90%。阻力分布测试表明，滤饼阻力分别占CAS和MBR总阻力的87.30%和94.18%。
