| 中文摘要 |
| 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100/4的条件下,污泥的沉降性能良好;在进水BOD/N分别为100/3和100/2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100/0.94的条件下,发生的非丝状菌膨胀最为严重.试验中还研究了氮缺乏条件下污泥微生物对氮源和磷源的利用率以及COD去除率的变化. |
| 英文摘要 |
| 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. |
