摘要
讨论了城市污水分别经过混凝沉降和A/O工艺处理后 ,将所产生的污泥分别用甲苯萃取 ,采用GC/MS测定了两种样品中的有机化合物含量。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 ;与原活性污泥相比较 。
In this paper,it is discussed that the results of two samples determined by GC/MS and the samples are respectively the active sludge and the sludge of coagulant subside extracted with methylbenzene as the extraction agent after the city waste are treated with the A/O and the coagulant subside respectively.The results show that the sorption is primary and the degradation is second of the active sludge in the treating city waste by the A/O.The active sludge is a more dangerous substance of second pollution.
