中文摘要：

采用固相萃取(SPE)-高效液相色谱(HPLC)法分析了广州市3个污水处理厂进出水中磺胺类和喹诺酮类抗生素共10种化合物的含量特征,并探讨其去除效果和环境排放量。结果表明,进水和出水中磺胺类抗生素总含量分别为3591.9～7782.5ng/L和2216.6～3591.9ng/L,喹诺酮类抗生素总含量分别为1539.4～2700.2ng/L和1284.4～5080.1ng/L。单个化合物的检出率在37.5%～97.5%,其中磺胺类抗生素以SMT、SM2和SM1为主,喹诺酮类抗生素以CIP和LOM为主。磺胺类和喹诺酮类抗生素的最高去除率分别为69.2%和27.2%,环境排放量分别为487.7～1512.3g/d和329.3～1117.6g/d。

英文摘要：

Occurrence of ten selected sulfonamides and fluroquinolone antibiotics were screened at three sewage treatment plants( STPs) in Guangzhou by high performance liquid chromatography( HPLC). The sum content of sulfonamides( ∑SAs) antibiotics in raw influent and final effluent from the three STPs ranged from 3,591.9 to 7,782.5ng/L and from 2,216.6 to 3,591.9ng/L respectively, and the sum content of fluroquinolone antibiotics( ∑FQs) were from 1,539.4 to 2,700.2ng/L in influent and from 1,284.4 to 5,080.1ng/L in ...
