| 摘要: |
| 针对一体式PAC／UF工艺的重要环节——曝气,通过小试和中试实验,研究曝气方式、曝气量等因素对一体式PAC／UF工艺运行及除污染性能的影响．结果表明:相对于间歇曝气,连续曝气情况下PAC／UF工艺去除有机物效果略好;连续曝气会使出水颗粒数略微增多;同时连续曝气可以更充分发挥粉末活性炭减缓膜污染的作用．增加曝气量也可以减缓膜污染．但是在实验条件下,间歇曝气可以节约电能0221 kW·h／m3．综合考虑PAC／UF工艺膜污染、除污染效能和运行成本,对于PAC／UF工艺,间歇曝气更经济合理． |

| Abstract: |
| Pilot-scale and bench-scale studies were performed to investigate the influence of aeration on hybrid PAC／UF process, in terms of pollutants removal and membrane fouling. The results showed that, compared with intermittent aeration, PAC／UF process had a better organic matter removal under continuous aeration condition. PAC could relieve the membrane fouling, and the function could be improved by the utilization of continuous aeration. Increasing aeration rate could relieve membrane fouling either. While intermittent aeration could save energy about 0221 kW·h／m3. Taking all factors into consideration, intermittent aeration was economical and reasonable for hybrid PAC／UF process. |
