摘　　要：以我国东北某市市政给水管网为研究对象，采用AOC和BDOC指标共同评价了管网水的生物稳定性。研究结果表明：管网水中AOC为39—379μg/L，BDOC为0．8～2．8mg／L，属于生物略不稳定的饮用水；随着管网的延长，水中的AOC和BDOC浓度总体上处于降低趋势，余氯浓度对AOC和BDOC浓度的变化均有较大影响；冬、夏两季节，管网水中AOC占BDOC的比例分别为5．8％和6．2％。The indexes AOC and BDOC were used to evaluate the biological stability of water in water distribution system in a northeast city of China. The results show that the concentrations of AOC and BDOC are 39 to 379 μg/L and 0.8 to 2.8 mg/L in water which is biologically unstable. The concentrations of AOC and BDOC generally decline with the prolongation of water distribution system. The residual chlorine has heavy influence on AOC and BDOC. The ratio of AOC in BDOC is 5.8% and 6.2% respectively in winter and summer.
