| 中文摘要 |
| 中空纤维膜生物反应器生活污水处理特性的试验研究结果表明:在HRT为1.5h、COD容积负荷为5.76kg/(cm3·d)条件下,均可实现90%以上的COD去除率;对NH3-N的去除率可稳定在90%以上。高MLSS浓度(8000-10000mg·L-1)提供了内部厌氧环境,使膜生物反应器的T-N去除率可达50%-60%.中空纤维膜生物反应器处理高效,不受冲击负荷影响,操作管理方便。其生物反应器体积比常规生物处理方法至少可减少一半。 |
| 英文摘要 |
| Study on domestic wastewater treatment property using Hollow Fiber Membrane Biological Reactor (HFMBR) was carried out in this paper.Research result suggested that under the condition of 1.5 hours HRT and 5.76 kg/(m3·d) COD volumetric load,90% removal rate of COD and NH3-N can be easily achieved.The removal rate of T-N can get to 50%—60% because of the inner anaerobic environment supplied by the high MLSS concentration (8000—10000 mg·L-1).HFMBR possesses the merits of high efficiency,immune to the shock loading and it is easy to manage. The volume of biological reactor can be half of that of traditional activated sludge or less. |
