| 摘 要： | 讨论了城市污水分别经过混凝沉降和A／O工艺处理时，污水中有机物的迁移和转化。所采用的方法是将原水、处理后的出水及污泥用甲苯萃取，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，对两种处理过程中有机物的迁移转化后进行了对比。结果表明，在A／O工艺处理城市污水过程中，吸附作用是主要的，降解作用是次要的。

| Abstract: | In this paper,the transfer and transformation of the organic substances was discussed in municipal wastewater treatment with methods of the A/O and the coagulantion subsidence.The samples of the primary water,the treated water and the sludge were prepared by means of the extraction of methylbezene as the extraction agent,and then the samples were analyzed by GC/MS.The contrasted results of two treating methods showed that the sorption is primary and the degradation is secondary municipal wastewater treatment by means of the A/O. |
