中文摘要：

采用活性炭／超滤膜（PAC／UF）组合工艺去除饮用水中的17a-乙炔基雌二醇（EE2），考察了EE2初始浓度、过滤速率、PAC投加量、水体中的阴离子合成洗涤剂及有机物等因素对PAC／UF组合工艺去除水体中EE2的影响。结果表明，单独UF对EE2的截留效果极差，截留率约为5％；PAC／UF组合工艺可有效去除水体中的EE2，且去除率随活性炭投加量的增加而线性增加；水体中的有机物和阴离子合成洗涤剂会降低组合工艺对EE2的去除效果。

英文摘要：

The combined process of powdered activated carbon （PAC） and ultrafiltration （UF） membrane was adopted to remove 17a-ethynyestradiol （EE2） in drinking water. The influences of the in- itial concentration of EE2, filtration rate, PAC dosage, anionic synthetic detergent and organic substances in water on removal of EE2 were investigated. The results show that single UF membrane has a poor rejection efficiency of EE2, and the removal rate of EE2 is only 5%. The combined process of PAC and UF membrane can remove EE2 effectively, and the removal rate increases linearly with the increase of PAC dosage. The anionic synthetic detergent and organic substances in water can decrease the removal efficiency of EE2.
