摘要
使用HPLC-MS/MS检测江苏某城市污水厂A中3种四环素抗生素分布状况,并利用质量平衡分析其在污水厂中的归趋及去除特性。结果显示进水中3种四环素含量分别是:四环素336 ng·L-1,土霉素202 ng·L-1和金霉素96 ng·L-1。而出水中只检测到四环素含量为130 ng·L-1,土霉素和金霉素都未检出。结合实测数据,通过质量平衡计算可知,污水厂A中污泥吸附对3种四环素的降解率分别为四环素28.8%,土霉素38.0%和金霉素34.9%。生物降解对3种四环素的去除率分别为四环素为32.5%,土霉素为62.0%,金霉素为65.1%。
HPLC - MS/MS was used to determinate the distribution and removal rate of tetracyclines in A wastewater treatment plant in Jiangsu prorince. The result showed that the three tetracyclines were dete,3ted. In influent water, the concentration of tetracyclines were from 96 ng·L-1 to 336 ng·L-1 , and in effluent water, only detect the tetracycline, whose concentration was about 130 ng·L-1. By the mass balance, in A wastewater treatment plant, the sludge adsorption remove about 28.8% of tetracycline, 38.0% of oxytetracycline and 34.9% of chlortetracycline; the biological degrada- tion remove about 32.5% of tetracycline, 62.0% of oxytetracycline and 65.1% of chlortetrtetrcycline.
