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总磷浓度的比值(以BOD/P计)对活性污泥膨胀的影响.结果表明,在进水中BOD/P为100/0.8以上的条件下,污泥的沉降性能良好;当进水中BOD/P分别为100/0.6和100/0.3时,出现高含水率的黏性菌胶团过量生长的现象,发生非丝状菌膨胀;在进水中BOD/P为100/0.4的条件下,发生更严重的非丝状菌膨胀.试验中还研究了磷缺乏条件下微生物对氮源和磷源利用率的变化.The influence of the concentration ratio of different organic substances and total phosphorus (counted as BOD/P) on activated sludge bulking was studied using sequencing batch reactor (SBR) fed with beer wastewater as the subject of research. The results showed that the sludge settled properly at a influent BOD/P of 100/0.8. When the BOD/P was 100/0.6 and 100/0.3 respectively, an excessive growth of viscous Zoogloea with high moisture content was observed and non-filamentous bulking occurred. When the value of influent BOD/P was 100/0.4, more serious non-filamentous bulking occurred. Furthermore, under the condition of phosphorus deficiency the effect of microorganism on the nitrogen and phosphorus sources utilization rate were also studied in the experiments.
