摘要： The anaerobic degradation characteristics of estrone (E-1), estradiol (E-2), and 17 alpha-ethinylestradiol (EE2) under single and combined conditions were investigated in batch tests and the influence of initial estrogen and sludge concentrations on the biodegradation process was studied. The results indicated that the degradation process of three estrogens was biphasic. The first phase was fast and the second phase was slow. The two phases could be described by the first-order degradation kinetics. In the single degradation experiments, at the fast stage, E-2 degradation rate was the highest for the three estrogens, which was 2 and 5.17 times higher than E-1 and EE2, respectively. However, at the slow stage, EE2 almost could not be biodegraded, and the degradation rate constant of E-1 and E-2 was 0.18 and 0.34 times lower than that at fast degradation phase, respectively. Meanwhile, E-1 was accumulated in the process of E-2 degradation, which indicated that E-1 was a main intermediate product of the E-2 anaerobic biodegradation. In the combined degradation experiments, the degradation rate constants of estrogens had the order of E-1 > E-2 > EE2, and the contribution of fast degradation stage was crucial to the removal of estrogens under anaerobic conditions. The degradation rate constant of estrogens decreased linearly with the initial estrogen concentrations and increased linearly with the sludge concentrations, which indicated that the higher sludge concentrations benefited the removal of estrogens under anaerobic conditions in the real wastewater treatment practice.
