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．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.
