| 摘 要： | 文章采用SBR法处理生活污水,研究了不同N元素含量(以BOD/N记)对活性污泥沉降性的影响。结果表明,在进水BOD/N为100/5和100/3的条件下,污泥沉降性良好;在进水BOD/N为100/1时,发生轻微由黏性菌胶团过量生长引起的非丝状菌膨胀。实验中还研究了在不同N元素含量时污泥微生物对COD去除率的影响以及污泥浓度(MLSS)的变化。

| Abstract: | Effect of different nitrogen content on settling property of activated sludge was investigated specially in some experiments carried on a sequencing batch reactor(SBR)fed with domestic wastewater.Experimental results showed that sludge settled properly at an influent value of BOD/N 100/5 and 100/3.When value of BOD/N was 100/1,non-filamentous activated sludge bulking caused by an excessive growth of viscous zoogloea with high moisture content occurred lightly.Effect of various nitrogen contents on COD remov... |
