中文摘要：

硫安类药剂抗菌素(SA ) 的出现在中国北京的六污水处理植物(STP ) 被调查。 13 客观抗菌素， sulfamethoxazole ，磺胺嘧啶， sulfamerazine ，磺胺嘧啶和 sulfamethizol 与 1.2 +/-的平均集中在 influents 被检测 0.45 ， 0.29 +/- 0.25 ， 0.048 +/- 0.012 ， 0.35 +/- 0.52 和 0.33 +/- 0.21 亩 g 中心点 L-1 ，分别地并且在自河的那些是 1.4 +/- 0.74 ， 0.22 +/- 0.19 ， 0.021 +/- 0.008 ， 0.22 +/- 第0.21a 0.01 +/- 0 亩 g 中心点 L-1 分别地。Sulfamethoxazole 是检测的占优势的混合物，并且与另外的二混合物磺胺嘧啶和 sulfamerazine 在所有废水样品被发现。磺胺嘧啶首先除了 sulfamethizol 在废水，和所有检测混合物的集中层次被报导，这应该被注意(在自河样品检测了一次) 在 influents 被观察类似于在自河的那些。从在这研究的数据， sulfamethoxazole，磺胺嘧啶， sulfamerazine 和磺胺嘧啶能部分在厌氧的过程在缺氧、氧气的处理联合起来并且反过来也如此被移开，这能被发现，它在自河导致了他们的低或平的否定移动率。在自河的 sulfamethoxazole 和磺胺嘧啶的集中上的增加在厌氧的处理联合起来由于他们的乙酰 ated 形式的简历转变可能被发现。另外， sulfamethoxazole 和磺胺嘧啶的简历降级能部分发生在缺氧、氧气的过程期间，这被观察，当 sulfamerazine 部分以厌氧、缺氧的单位被消除时。

英文摘要：

The occurrence of sulfonamide antibiotics （SAs） was investigated in the six sewage treatment plants （STPs） of Beijing, China. Of the 13 objective antibiotics, suIfamethoxazole, suIfapyrldine, suIfamerazine, sulfadiazine and suIfamethizol were detected in the influents with the average concentrations of 1.2 ± 0.45, 0.29 ± 0.25, 0.048 ± 0.012, 0.35 ± 0.52 and 0.33 ± 0.21 μg·L^-1, respectively, and those in the effluents were 1.4 ± 0.74, 0.22 ± 0.19, 0.021 ± 0.008, 0.22 ± 0.21and 0.01± 0 μg·L^-1, respectively. SuIfamethoxazole was the predominant compound detected, and was found in all wastewater samples with the other two compounds sulfapyridine and suIfamerazine. It should be noted that suIfadiazine was first reported in wastewatera, and the concentration levels of all detected compounds except for suIfamethizol （detected once in the effluent samples） in the influents were observed to be similar to those in the effluents. From the dsts in this study, it can be found that suIfamethoxazole, suIfapyridine, suIfamerazine and suIfadiazine could be partly removed in anoxic and aerobic treatment unit and vice versa in anaerobic process, which led to their low or even negative removal rates in the effluents. The increase on the concentrations of suIfamethoxazole and suIfapyridine in the effluents was found probably due to the biotransformation of their acetylated forms in anaerobic treatment unit. In addition, it was observed that the biodegradation of suIfamethoxazole and suIfapyridine could partly occur during the anoxic and aerobic process, while suIfamerazine was partly eliminated in the anaerobic and anoxic units.
