| 摘 要： | 结合给水管网中饮用水微生物再生长现象,分析了AOC作为反映饮用水生物稳定性的替代参数所存在的问题。根据饮用水处理系统中微生物营养的种类及特点,以及磷在微生物生长和代谢过程中的关键作用,提出同时检测和控制磷含量来保证饮用水生物稳定性的观点,并对磷和AOC共同作为饮用水生物稳定性控制指标的可行性进行了探讨。

| Abstract: | The problems caused by using parameter assimilable organic carbon (AOC) as a surrogate indicator for the biological stability of drinking water were discussed combined with the appearance of microbial regrowth inside the drinking water distribution lines. The kinds and characteristics of nutrients used by microorganisms in water were investigated and on the basis of concerning the key effect of phosphorus in growth and metabolism of microorganisms, it was proposed that the bio-stability of the drinking water could be ensured by way of simultaneous monitoring and control of P content and AOC level. The feasibility to use both phosphorus and AOC as control index for drinking water bio-stability has been approached. |
