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 .
The transfer and transformation of the organic substances are discussed in treating city wastewater with methods of the A/O and the coagulating subside. The samples of the primary water, the treated water and the sludge are prepared by means of the extraction of n butyl acetate as the extraction agent, and then the samples are analyzed by GC/MS. The contrasted results of two treating methods show that the sorption is primary and the degradation is secondary in treating city wastewater by means of the A/O.
