| 摘 要： | 讨论了城市污水经过A／O工艺处理时活性污泥的二次污染问题。将原水、处理后的出水及活性污泥用甲苯萃取，萃取相经过真空浓缩后，采用GC／MS测定了样品中的有机化合物，结果表明，在A／O工艺处理城市污水过程中，活性污泥的吸附作用是主要的，降解作用是次要的；A／O工艺所排放的活性污泥仍然是一种危险的污染物。

| Abstract: | The second pollution of the active sludge was discussed in municipal wastewater treatment with method of the A/O. The samples of the primary water, the treated water and the active sludge were prepared by means of extraction of methybezene. Enrichment under vacuum, and then the organic substances in the samples were determined by the GC/MS. The results showed that the absorption was primary and degradation was second of the active sludge. The active sludge was still a dangerous contaminant. |
