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。所采用的方法是将原水、处理后的出水及活性污泥用乙酸丁酯萃取 ,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。
The second pollution of the active sludge was discussed in municipal wastewater treatment with method of the A/O.The experimental method was that the samples of the primary water,the treated water and the active sludge were prepared by means of extraction of n butyl acetate as the extraction agent,enrichment under vacuum,and then the organic substances in the samples were determined by the GC/MS.The results showed that the sorption was primary and degradation was second of the active sludge.The active sludge was still a dangerous contaminant.
