| 摘 要： | 根据课题组和他人的研究结果,比较了四种常用的消毒剂对饮用水中可同化有机碳(AOC)含量的影响,并得出初步结论:除紫外消毒外,其它几种消毒剂都会不同程度的造成水中AOC浓度的增加,其增加的程度与消毒剂的氧化能力、剂量以及水中有机物的含量、性质密切相关;从去除水中AOC的角度来说,臭氧消毒和臭氧-生物活性炭工艺会在一定程度上增加水中AOC的含量,导致饮用水的生物稳定性降低,而常规处理和强化常规处理则可去除水中一定量的AOC,优于臭氧生物活性炭工艺;我国部分城市的管网中普遍存在着细菌等微生物的再生现象.

| Abstract: | According to the results of the research,the paper presents a specification to the influence of the 4 popular disinfectants on the assimilable organic carbon(AOC) in the drinking water and draws some preliminary conclusions: Except for UV,other disinfectants can increase the concentration of the AOC to some extent,depending on the oxidized ability,dosage,the content and characteristics of the organic matters.Ozonization and O3-BAC can't remove AOC effectively from the water and bring down the biological stability,while coinventional treatment technologies can remove more AOC and microbiology.It is popular that the regrowth of bacteria are in wide distribution in China. |
