药物滥用及医药废水滥排引发的水污染问题日趋严重，其中作为抗生素大类的青霉素残留处理引起人们广泛关注。将阿莫西林、氨苄青霉素和青霉素G钠3种典型青霉素类抗生素作为处理对象，考察了反应时间、初始pH、曝气条件及铁炭质量比对其去除效果的影响。结果表明，在pH=3、铁炭质量比为2∶1、温度为25℃、持续曝气360 h的条件下，3种青霉素类抗生素的去除率分别达到61.90%、82.49%和97.03%。通过设置对照实验探究反应过程，结果发现，在降解过程中起主要作用的是电化学氧化还原，其次为活性炭的吸附和Fe（OH）₃的混凝。

In recent years, water pollution caused by the abuse of drugs and the excessive discharge of pharmaceutical wastewater has become increasingly serious.Of which, the residues and treatment of penicillin, a bulk antibiotic, have attracted wide public attentions.In this study, three typical penicillin antibiotics including amoxicillin, ampicillin and penicillin G sodium are selected as research objects, and the effects of reaction time, initial pH, aeration conditions and the mass ratio of iron/carbon on removal efficiency of these penicillin-series antibiotics are examined.The results show that the removal rates of these three antibiotics can reach 61.90%, 82.49% and 97.03% respectively when the reaction lasts for 360 h, the initial pH is 3, the mass ratio of iron/carbon is 2:1 and the reaction temperature keeps at 25℃.In order to explore the reaction mechanism, control groups are set and the experiments draw a conclusion that the electrochemical oxidation reduction play a major role in the degradation process, followed by the adsorption via activated carbon and the coagulation by Fe(OH)₃.
