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．
The bio-stability of ozone in the oxidation of tap water in a petrochemical area was studied using assimilable organic carbon (AOC). The results showed that the AOC content of the groundwater raw water was 413μg/L. It had no biological stability and the water source was polluted by organic matter. Ozone oxidation increased the AOC in water by 7 times, the activated carbon adsorption AOC was 257 μg/L, and the ozone-disinfected AOC was 258 μg/L. Ozone oxidation combined with activated carbon adsorption in a petrochemical area can effectively reduce the AOC content, but the high AOC in the raw water makes the process water still not have biological stability.
