| 摘 要： | 采用循环活性污泥法处理模拟丙烯腈废水，探讨了丙烯腈的微生物降解机理。实验结果表明：在进水1h、厌氧1h、曝气4h、沉淀1h的处理条件下，处理后丙烯腈质量浓度由71mg/L降至4．4mg/L，去除率为93．8％COD由546mg/L降至49mg/L，去除率为91％。用扫描电子显微镜观察反应器中的活性污泥，发现八叠球菌、诺卡氏菌、链球菌为其主要菌群。 |

| Abstract: | Simulated acrylonitrile wastewater was treated by cyclic activated sludge process and the mechanism of acrylonitrile biodegradation was discussed. The experimental results show that after water - feeding for 1 h, anaerobic treatment for 1 h, aeration for 4 h and precipitation for 1 h, the mass concentration of acrylonitrile and COD were reduced from 71 mg/L to 4.4 mg/L and from 546 mg/L to 49 mg/L respectively. The removal rates of acrylonitrile and COD were 93. 8% and 91% respectively. Bacteria of Sarcina sp., Nocardia sp. and Streptococcus sp. are found as main flora by observing activated sludge in the reactor with scanning electron microscope. |
| Keywords: | cyclic activated sludge process acrylonitrile wastewater treatment |
