A/O法处理城市污水中有机物迁移转化的研究(Ⅱ)

本文通过实验方法对采用A／O工艺处理城市污水过程中有机物的迁移和转化进行了研究。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，采用色谱-质谱法(GC／MS)对样品中的有机化合物进行了测定。结果表明，在A／O工艺处理城市污水过程中，活性污泥对有机物的吸附作用是主要的，降解作用是次要的。

STUDY ON TREATING SOME ORGANIC SUBSTANCES IN MUNICIPAL WASTEWATER PROCESSING BY A/O(Ⅱ)

The paper has given a detailed discussion on the transfer and transformation of some organic substances gained from the municipal sewage treatment with the so-called A/O method. As is known, the general approach is to take the sample from the primary water, the water treated and the active sludge, which is prepared by extracting methyl benzene as an agent, then being enriched in vacuum condition. And then the organic substances in the samples can be determined by using the GC/MS. The author's experimental results show that the absorption of the active sludge is dominant and the degradation of the active sludge follows.
