摘要:

系统地论述了国外膜生物反应器在污水处理中的研究进展。国外膜生物反应器在污水处理中的应用范围和规模不断增加,然而,膜污染依然是影响其推广应用的主要障碍。值得注意的是,采用空气喷射方式在中空纤维膜内形成活塞流,可有效减轻膜污染和提高膜通量。经济分析表明中小规模的污水处理厂可能采用膜生物反应器更便宜,但大规模的污水处理厂宜采用常规工艺。现代分子生物技术为研究和了解膜生物反应器中的微生物群落提供了新的方法和手段。

Abstract:

Developments of membrane bioreactors (MBR) for wastewater treatment in foreign countrie are thoroughly reviewed. The scale and amount of MBR applied to wastewater treatment are expanding, however, membrane fouling is mainly the abstructive factor of applying MBR further to wastewater treatment. It is noted that air sparging in hollow fibre module is efficient for ameliorating membrane fouling,though there are many countermeasures of membrane fouling in MBR. The cost analysis shows that the application of MBR may be much cheaper in small/midscale wastewater treatment plants, but conventional activated sludge processes are more suitable for largescale wastewater treatment plants. The molecular biological technique allows us to study microbial community of membrane bioreactors at the genetic level.

Key words: membrane bioreactors, wastewater treatment, activated sludge
