| 中文摘要 |
| 采用可同化有机碳(AOC)研究某石化地区臭氧氧化自来水的生物稳定性。结果表明,地下水原水AOC含量为413μg/L,不具有生物稳定性,水源遭到有机物污染。臭氧氧化使水中AOC增加7倍,活性炭吸附出水AOC为257μg/L,再经臭氧消毒AOC为258μg/L.某石化地区臭氧氧化结合活性炭吸附能有效减少AOC含量,但原水中过高的AOC使工艺出水仍不具有生物稳定性。 |
| 英文摘要 |
| Assimible organic carbon(AOC)test was used to study the influence on the biological stability of drinking water by ozonation in a water works located in a certain petrochemical industrial area.The results showed that the concentration of AOC in raw water is 413 μg/L,it means that biological unstability exists apparently in the underground source water and the source water is polluted by local industry.The concentration of AOC increases sharply with ozonation and goes up to 3069 μg/L,however,it reduces to 257 μg/L by granular activated charcoal absorption,after disinfection by ozone it maintains at 258 μg/L.Through the treatment process the concentration of AOC can be decreased effectively,there still remains biological unstability in the effluent becouse of the high concentration of AOC in raw water. |
