| 摘 要： | 采用超滤与粉末活性炭组合工艺处理某水厂沉淀池出水,对比不同浓度（0、10、20和40mg/L）粉末活性炭对水中污染物的去除及对膜运行性能的影响。结果表明,随着粉末活性炭浓度的增加,粉末活性炭-超滤组合工艺对UV254和CODMn的去除效果也增强。同时,粉末活性炭可以有效延缓膜污染,对维持超滤膜长时间稳定运行起到重要作用,膜在污染后经过化学清洗后可以基本恢复。

| Abstract: | The combined process of the powdered active carbon（PAC） and the ultrafiltration（UF） was used to treat effluent of sedimentation tank in a waterworks.The influences of the PAC dosage（0、10、20 and 40 mg.L-1） on the UF were studied.The results showed that adding PAC to the system could enhance the removal efficiencies of the PAC-UF for CODMn,UV254.The larger amount PAC added,the higher removal efficiency achieved.The addition of PAC could mitigate membrane fouling,and played an important role in the long-time stable operation of the PAC.And the performance of membrane could be recovered after chemical backwashing. |
