某饮用水处理厂中5种抗生素的去除
Removal of five antibiotics from a drinking water treatment plant
摘要
Abstract
The study showed the removal performance of the five target antibiotics (clarithromycin(CLA) , erythromycin-H2O(ERY) , levofloxacin( LEV) , sulfamethoxazole(SUL) and trimethoprim(TRI)) in each treatment process of drinking water treatment plants in the U. S. The removal efficiency was analysed via the influence of time and space, respectively, and the relationship between the removal rate of antibiotics and water quality parameters was discussed. The results showed that the average concentrations of the five antibiotics in source water ranged from 0 to 26. 8 ng/L, while 0 to 2. 3 ng/L in effluent. The total removal efficiency of the antibiotics in the water treatment processes was 79. 5% with CLA 92. 8% ,ERY 24% ,LEV 100% ,SUL 85. 7% ,TRI 53. 2% .respectively. The residual concentration of these antibiotics in each sampling place at different sampling time all showed that autumn' s got to the highest, but the removal rates of different treatment units weren' t the same in different seasons. CLA could be used as an indicating antibiotic to predict the trend of the total concentration of antibiotic. There was a good positive correlation between the value or removal rate of UV254 and those of the antibiotics. So we could forecast the fate of the antibiotics by calculating the value and removal rate of UV254. It provided the basis to the plant design and choice of treatment processes in China with the research about removal performance of five antibiotics from drinking water treatment plants.关键词
