  • 摘要: 以南京某城市污水厂污水和污泥中的酞酸酯类（PAEs）为研究对象，分别采用固相萃取-气相色谱-质谱联用（SPE-GC-MS）和超声提取-气相色谱-质谱联用（USE-GC-MS）检测其中的优先控制污染物邻苯二甲酸二甲酯（DMP）、邻苯二甲酸二乙酯（DEP）、邻苯二甲酸二丁酯（DBP）和邻苯二甲酸单（2-乙基己基）酯（MEHP），研究其在厌氧/好氧（A/O）污泥处理过程中的分布特征及降解规律。研究结果表明，各类PAEs在该污水厂的污水和污泥中均有检出，二级处理出水中4种酞酸酯类物质的浓度在0.151~2.419 μg/L。污水中4种酞酸酯的分布规律为MEHP>DBP>DMP>DEP，污泥中4种酞酸酯的分布规律为MEHP>DBP>DEP>DMP。该污水厂二级处理工艺对4种PAEs的去除效果较明显，去除效率DBP>DEP>DMP>MEHP。
    Abstract: Used phthalate acid esters (PAEs) as analyzed objects, SPE-GC-MS and USE-GC-MS techniques were adopted respectively to detect some of the priority controlled ones, such as dimethyl phthalate (DMP),diethyl phthalate(DEP), dibutyl phthalate (DBP), and mono-(2-ethylhexyl) phthalate (MEHP) in sewage and sludge samples in a sewage treatment plant in Nanjing, so as to achieve their distribution characteristics and degradation rules during the sludge A/O process. It was indicated that all of these object PAEs were found in the sewage and sludge in the sewage treatment plant. The concentration of the studied PAEs in the effluent from the secondary treatment system was 0.151~2.419 μg/L. The concentration order of them in the effluent was MEHP>DBP>DMP>DEP, and in the sludge it was MEHP>DBP>DEP>DMP. It was indicated that the four PAEs were removed effectively by the secondary processing in the plant, and their removal efficiencies order was DBP>DEP>DMP>MEHP.
