甾体雌激素在不同污水处理工艺中的去除规律
Removal of steroid estrogens in different wastewater treatment processes
摘要
Abstract
Removal efficiency of steroid estrogens in four different wastewater treatment plants (WWTPs) with advanced treatment processes was studied using gas chromatography-mass spectrometry. The results show that all of the five estrogens are detected in the four WWTPs, and the concentrations of estrone, 17βestradiol and estriol are from 15.1 to 607.0 ng/L, which is higher than that of foreign countries. The average removal rate of estrone, estriol and ethinyl estradiol is 88.1%-97.3%, which is higher than that in tranditional WWTPs. The biological treatment process is dominant for the removal of estrogens and the removal effect of estrogens is better in activated sludge system than that in biological membrane system. Sedimentation pretreatment and advanced treatment processes of coagulation, sedimentation and filtration are not good for the removal of steroids, with average revomal rate of 10%-20%. Steroid estrogens can not be removed completely in the 4 WWTPs, which results in the high residues of estrogens in both effluent and discharged sludge.关键词
