摘　　要： 以啤酒废水为研究对象,用SBR法研究了进水中不同有机物与营养物缺乏程度(以BOD/N/P计)对活性污泥膨胀的影响。结果表明,在进水中BOD/N/P为100/4/0.8以上的条件下,污泥的沉降性能良好;当进水中BOD/N/P为100/3/0.6、100/2/0.4及100/0.9/0.3的条件下,均出现丝状菌的过量生长,发生丝状菌污泥膨胀。同时还研究了对这种丝状菌污泥膨胀的控制。 The effect of nutrient deficiency (evaluated by BOD/N/P) on activated sludge bulking was studied specially in some experiments carried on a sequencing batch reactor fed with beer wastewater in paper. The experimental results showed that the sludge settled properly at a influent BOD/N/P value being 100/4/0.8. When the values of BOD/N/P were 100/3/0.6, 100/3/0.6, 100/2/0.4 and 100/0.94/0.3 respectively, an excessive growth of filamentous bacteria was observed and filamentous activated sludge bulking occurred. Furthermore, the control methods of filamentous bulking were studied in the experiments.
