| 摘 要： | 用固相萃取-气相/质谱方法检测分析了某典型污水处理厂各水处理单元中内分泌干扰物质(EDCs)的存在情况,在污水、污泥中共计检出30种内分泌干扰嫌疑物质.结果表明,各种EDCs在水处理过程中的去除率为70%～99%,其中污泥吸附对EDCs的去除起着重要作用.污泥中酚类物质浓度为17～35mg/kg,酞酸酯类物质浓度为25～77mg/kg,多环芳烃类物质为1.33～1.74mg/kg.同国外报道的结果相比,该污水处理厂水处理流程中酚类、酞酸酯类以及多环芳烃类的含量均处于较低的水平.

| Abstract: | Endocrine disrupting chemicals (EDCs) existed in the water treatment units of Beijing based Sewage Treatment Plant were analyzed by SPE-GC/MSD and GC/ECD. Totally 30 EDCs were detected from the influent, effluent and sludge. The results show that about 70%-99% EDCs in the influent were removed after treatment. Sludge adsorption played an important role in the reduction of EDCs. The range of phenols in sludge was 17-35 mg/kg, the range of PAEs was 25-77 mg/kg and the range of PAHs was 1.33-1.74 mg/kg. Compared with the results in other countries in literature, the existence of EDCs in the Sewage Treatment Plant was not serious. |
