Abstract

The combined process of powdered activated carbon(PAC) and ultrafiltration(UF) membrane was adopted to remove 17α-ethynyestradiol(EE2) in drinking water.The influences of the initial 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.
