| 中文摘要 |
| 针对污泥混合液的过滤性能,在运行条件相同的情况下对膜生物反应器(MBR)与传统活性污泥法(CAS)进行比较.实验结果表明:MBR工艺污泥混合液的过滤阻力是CAS工艺过滤阻力的2～3倍;2种工艺悬浮液过滤阻力占总阻力的90%左右.过滤阻力分布实验表明,沉积层阻力占CAS工艺总阻力的87.30%,占MBR工艺总阻力的94.18%. |
| 英文摘要 |
| 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 2～3 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. |
