摘　　要：利用实验室建立的模拟给水管网系统和现场试验 ,对管网中细菌的再生长现象进行了调查 .研究了作为水生物稳定性评价指标的生物可同化有机碳 (AOC)在给水管网中的变化 ,结果表明 :AOC在给水管网中的变化受余氯和细菌活性的双重影响 ,其浓度一般随管网延伸而先减少后增加 .氯化消毒对细菌有灭活作用 .运用纳滤技术 ,并以砂滤、臭氧活性炭组合工艺为预处理工艺 。Bacterial regrowth was investigated in a simulated water distribution system and an actual water supply network with assimilable organic carbon(AOC) used for assessment The variation of AOC is based on the chlorine residual and bacterium activity, and its concentration decreased first and then increased with the extension of water distribution system. The chlorination of water is now usually to limit bacterial growth in the distribution system. The combination of sand filter ,ozone and granular activated carbon was chosen for pretreatment of nanofiltration.The treatment of nanofiltration had a high bacterium removal ratio
