摘　　要：对城市污水处理厂各处理单元中的金属和抗生素进行分析测定,研究了常见金属离子和抗生素在污水处理过程中的分布特征.结果表明,工艺中Fe、Mn含量较高,经处理后达到环境排放标准,生化污泥的吸附在金属的去除中起主要作用.原水中检出的抗生素主要为磺胺类、氧氟沙星和氯霉素,处理工艺中磺胺类总去除率为48.9%~64.7%,氧氟沙星去除率为66.5%,而氯霉素去除率仅为22.0%,对抗生素去除起主要作用的是生化处理单元.The metals and antibiotics demanded in each treatment unit of urban sewage treatment plant are analyzed. The distribution characteristics of common metal ions and antibiotics in the sewage treatment process are studied. The results show that the contents of Fe and Mn in process are higher and they can reach environmental standards after being processed. The removal of metal is mainly reflected in the action of biochemical sludge adsorption. The antibiotics detected in the raw water are mainly sulfonanmides, ofloxacin and chloramphenicol. The removal rate of sulfonamides is in the range of 48.9% ~ 64.7%, the ofloxacin is 66.5%, and the chloramphenicol is only 22.0%, respectively. Antibiotic removal is mainly in the unit of biochemical pool treatment.
