摘　　要：为了考察进水磷缺乏对活性污泥系统的影响,采用4个序批式反应器(SBR),按照缺氧/好氧的方式运行,通过调节不同的进水COD/TP值,考察了磷缺乏状态下活性污泥的沉降性、絮体形态、胞外聚合物含量以及出水水质。结果表明,当进水COD/TP值≥100/0.4时,活性污泥系统发生非丝状菌膨胀;当进水COD/TP值≤100/0.4时,活性污泥系统具有良好的硝化能力。当进水COD/TP值≥100/0.2时,系统硝化过程受到抑制,出现亚硝酸盐积累。在进水COD/TP值为100/0.2和100/0.1的条件下,亚硝酸盐积累量分别高达5.40和4.66 mgN/gVSS。在进水磷缺乏状态下,活性污泥系统去除COD的能力并未受到明显的影响。In order to study the influence of phosphorus shortage on activated sludge system, 4 se- quencing batch reactors （SBR） were operated with an anoxic-oxic pattern in parallel under different de- grees of phosphorus deficiency. The sludge settleability, floc morphology, EPS content and effluent quali- ty were investigated. The results showed that when the influent COD/TP was more than or equal to 100/ 0.4, non-filamentous activated sludge bulking occurred. When the influent COD/TP was less than or e- qual to 100/0.4, the activated sludge system had good nitrification ability. When the influent COD/TP was more than or equal to 100/0.2, nitrification was restrained, and nitrite accumulation occurred. When the influent COD/TP was 100/0.2 and 100/0.1, the accumulations of nitrite were 5.40 mgN/ gVSS and 4.66 mgN/gVSS, respectively. COD removal was not significantly affected by phosphorus shortage.
