Abstract

Additional phosphorus will be introduced to water sample if the conventional procedure is used to measure assimilable organic carbon (AOC) in drinking water. It has been shown that there are the cases that phosphorus is the limiting nutrient for microbial growth in drinking water. The measured value of AOC would not be able to indicate appropriately the regrowth potential of bacteria in this case. The conventional procedure used to measure AOC was modified to avoid the introduction of additional phosphorus to water sample in this study. It was shown that it was feasible to measure AOC in water using the modified procedure. Furthermore, the measured value of AOC determined by the modified procedure could indicate appropriately the regrowth potential of bacteria in drinking water despite either organics or phosphorus was the limiting nutrient for bacterial regrowth.

摘要

如果采用常规方法测量饮用水中的可同化有机碳（AOC），会向水样中引入额外的磷。研究表明，存在磷是饮用水中微生物生长的限制营养物的情况。在这种情况下，AOC的测量值无法准确指示细菌的再生长潜力。本研究对用于测量AOC的常规方法进行了改进，以避免向水样中引入额外的磷。结果表明，使用改进后的方法测量水中的AOC是可行的。此外，无论有机物还是磷是细菌再生长的限制营养物，通过改进方法测定的AOC测量值都能准确指示饮用水中细菌的再生长潜力。
