| 内容記述 | The behavior of the highly potential endocrine disrupters 17B-estradiol （E2） and estrone （E1） was investigated in an air-fluidized-bed biofilm reactor system, which consisted of an oxidation reactor, a nitrification reactor and a denitrification reactor using a polypropylene carrier, for advanced sewage treatment. E2 and E1 concentrations were determined using an enzyme-linked immunosorbent assay （ELISA） kit. The effluent concentrations of total organic carbon and total nitrogen from the denitrification reactor were maintained at 8 mg-C/L and 5 mg-N/L, respectively, under a total hydraulic retention time of 4 hr in the biological process. The removal of nitrogen as advanced sewage treatment was achieved by the system. However, the removal efficiencies of E2 and E1 in the biological process were less than 70% and 40%, respectively. Over three weeks, the average estrogen concentrations in the effluent of the denitrification reactor were 2.6 ng/L for E2 and 28.2 ng/L for E1. Although the system successfully achieved advanced treatment, the removal efficiency of natural estrogens was lower than that for a conventional activated sludge plant. The advanced treatment of municipal sewage must be promoted to improve the aquatic environment, while it is necessary to take into account the fate of estrogens in the process. | |||||
