| 摘 要： | 以生物可同化有机碳（AOC）作为饮用水生物稳定性的评价指标，对常规处理工艺和臭氧／生物活性炭（O3／BAC）深度处理工艺控制AOC的效果进行了研究。结果表明：两种工艺都会使出厂水的生物稳定性变差，常规处理工艺和深度处理工艺使出厂水的AOC平均浓度分别增加了26％、70％；尽管砂滤和BAC滤池去除AOC的效果良好，但O3氧化和氯胺消毒会大幅度提高AOC浓度。因此，有必要采取减少后臭氧投加量或单独采用BAC、增加生物滤池接触时间以及减少消毒剂投加量等措施来控制AOC浓度，促使出厂水水质达到生物稳定。

| Abstract: | The variation of the AOC control index for water biological stability in traditional and O3/BAC advanced water treatment processes was studied.The results show that both the traditional and advanced treatment processes worsen the biological stability of the finished water,and the AOC concentration is increased by 26% and 70% respectively.Although the sand filter and BAC filter remove AOC effectively,ozonation and chloramine disinfection can increase the AOC concentration prominently.Therefore,the measures s... |
