中文摘要：

为评价和考察厌氧序批式反应器（AnSBR）对生活污水中9种典型环境雌激素的去除效果和机制,采用固相萃取（SPE）——LC/MS/MS分析方法,分析所选环境雌激素的浓度和污泥吸附量.结果表明：大豆苷元,4-t-辛基酚（OP）,4-n-壬基酚（NP）和染料木素的检出浓度高于其他5种环境雌激素;厌氧污泥对NP,OP,雌酮（E1）,17α-乙炔基雌二醇（EE2）和17β-雌二醇（E2）的吸附作用明显;大豆苷元和染料木素的去除率在60%以上;大豆苷元、染料木素和雌三醇（E3）的主要去除机制为生物降解作用,EE2,OP和NP的去除是生物降解、污泥吸附的共同作用.

英文摘要：

Solid phase extraction LC/MS/MS detection method was applied to study the removals of nine selected estrogenic endocrine disruptors （EEDs） in an anaerobic sequencing batch reactor （AnSBR）. The concentrations and occurrences of 4-n-nonylphenol （NP）, 4-t- octylphenol（OP）, Daidzein and Genistein were higher than those of the other five EEDs. Sludge adsorptions of NP, OP, estrone （E1）, 17α- ethinylestradiol （EE2） and 17β-estradiol （E2） were relatively higher within the selected EEDs. Removal rates of Daidzein and Genistein were above 60%. The results obtained indicated that biodegradation was the major removal pathway for Daidzein, Genistein and estriol in AnSBR, while both sludge adsorption and biodegradation contributed to the removals of EE2, OP and NP.
