考察C、N、P等饮用水中的限制性营养元素对微生物再生长的影响。结果表明，磷是管网中细菌生长的主要限制因子，饮用水最适合细菌生长的最佳C：P为100：5。另外，对于管网微生物而言，乙酸碳等易降解有机物是一种更容易被利用的有机物。因此，在饮用水处理过程中应尽可能地去除原水中磷，使出厂水TP控制在5μg／L以下，同时要防止饮用水被一些有机物特别是小分子易降解有机物污染，以确保饮用水安全。
攷察C、N、P等飲用水中的限製性營養元素對微生物再生長的影響。結果錶明，燐是管網中細菌生長的主要限製因子，飲用水最適閤細菌生長的最佳C：P為100：5。另外，對于管網微生物而言，乙痠碳等易降解有機物是一種更容易被利用的有機物。因此，在飲用水處理過程中應儘可能地去除原水中燐，使齣廠水TP控製在5μg／L以下，同時要防止飲用水被一些有機物特彆是小分子易降解有機物汙染，以確保飲用水安全。

The impacts of C, N and P on bacteria regrowth in pipe networks were studied. The results showed that P acted as the major restrictive factor for bacteria growth in pipe network; while the drinking water was most suitable for bacterial growth when the C :P ratio is 100:5. In addition, easily biodegradable organic compounds, such as acetic acid carbon were adaptable to the network micro - organisms. Therefore, P in raw water should be removed as much as possible in a bid to keep the total P to less than 5 μg/L in the drinking water treatments process. In order to ensure drinking water safety, drinking water should be pre- vented from contamination by organic compounds, especially easily biodegradable micro -organic compounds.
