摘　　要：以可同化有机碳(AOC)和生物可利用磷(MAP)作为水质生物稳定性的评价指标,通过静态试验考察氯胺投量和反应时间对水质生物稳定性的影响.结果表明,氯胺投加量和反应时间均对出水AOC及MAP产生影响,水样中ρAOC及ρMAP变化范围较小,反应速率慢,ρAOC及ρMAP的增减与氯胺投量不成正相关,氯胺消毒对MAP的影响相对AOC较小,但鉴于微生物对碳、磷的需求特点,氯胺消毒对MAP的影响不能忽略.The effects of chloramine dosages and reaction time on the water biological stability were studied by the static test, using assimilable organic carbon （AOC） and microbially available phosphorus （MAP） as evaluation index. The results show that AOC and MAP in the treated water are influenced by chloramine dosage and reaction time. With small varying range of AOC and MAP concentration and slow reaction rate, the change of AOC and MAP concentration were not positively correlated with chloramine dosage, and MAP was less affected by chloramine dosage than AOC. According to the characteristics of the microbial demand for carbon and phosphorus, the influence of chloramine disinfection to MAP should be considered too.
