摘　　要：采用SBR法处理啤酒废水 ,研究了进水中不同有机物与总氮的比值 (以BOD/N计 )条件对活性污泥膨胀的影响 .结果表明 ,在进水BOD/N为 1 0 0 / 4的条件下 ,污泥的沉降性能良好 ;在进水BOD/N分别为 1 0 0 / 3和1 0 0 / 2时 ,均发生由高含水率的粘性菌胶团过量生长引起的非丝状菌膨胀 .在进水BOD/N为 1 0 0 / 0 94的条件下 ,发生的非丝状菌膨胀最为严重 .The effect of nitrogen dificiency on activated sludge bulking was studied specially in some experiments carried on a sequencing batch reactor fed with beer wastewater in this paper.The experimental results showed that the sludge settled properly at a influent BOD/N value of 100/4.When the value of BOD/N was 100/3 and 100/2 respectively,non\|filamentous activated sludge bulking caused by an excessive growth of viscous \%Zoogloea\% with high moisture content occurred.When the value of influent BOD/N was 100/0 94,more serious non\|filamentous bulking occurred.Furthermore,the effect of nitrogen deficiency on the nitrogen sources and phosphorus sources utilization rate and the COD removal rate was studied in the experiments.
