[目的]比较各种营养元素对饮用水中细菌再生长的限制作用.[方法] 在碳、磷、氮及各类无机盐投加条件下,测定各水样的细菌再生长潜力.[结果] 添加不同营养元素后,水样的BRP均有增加,饮用水中细菌再生长受到多种营养元素限制作用的影响;各种营养元素对细菌生长限制作用的强弱,将由各营养元素含量间的相对关系决定,并随着净水工艺的变化而变化.[结论] 碳元素(有机物)对各水样细菌生长均表现出明显的限制作用,说明有机碳是太湖流域地区饮用水系统中细菌再生长的主要营养限制因子.

[Objective] The aim of the study was to compare limiting effects of various nutrients on bacterial regrowth in drinking water.[Method] Bacterial regrowth potential (BRP) method was used to investigate the limiting effects of carbon, phosphorus, nitrogen and other minerals on bacterial regrowth in drinking water.[Result] BRP was increased when nutrients was added to the water sample.Bacterial regrowth in drinking water would be limited by various nutrients jointly.The limiting effects of different nutrients was depended on the concentration ratios among various nutrients, and varied with water treatment processes.[Conclusion] Carbon had a stronger limiting effect than other nutrients in the source water, treated water and advanced treatment effluent investigated in the experiment, which indicated that carbon was the primary limiting nutrient on bacterial regrowth in drinking water in Tai Lake district.
