摘要:
分析了上海市某生活垃圾焚烧厂渗滤液处理系统中3 类18 种抗生素的赋存特征与归趋情况。结果表明，渗滤液原液中磺胺类（SAs）、喹诺酮类（FQs）和大环内酯类（MLs）抗生素的浓度分别为508.3~613.8、1 471~2 073、931~1 466 ng/L。渗滤液经厌氧—两级缺氧/好氧生化系统处理后，SAs、FQs、MLs三类抗生素的去除率分别为95.4%、60.9%、99.3%，生化处理可有效降解SAs和MLs抗生素，但对FQs抗生素的降解效果较差；FQs抗生素经污泥吸附后的去除率为7.6%~17.7%，SAs和MLs抗生素在污泥中的含量则都低于5%。污泥吸附在抗生素去除方面的占比较低，渗滤液中的抗生素主要通过生化处理被去除，微生物降解是抗生素在渗滤液处理过程中被去除的主要机制。
Abstract:
This paper analyzed the occurrence characteristics and fate of 3 groups of 18 antibiotics in the leachate treatment system of a domestic waste incineration plant in Shanghai. The concentration ranges of sulfonamides (SAs), quinolones (FQs) and macrolides (MLs) in the original leachate were 508.3-613.8 ng/L, 1 471-2 073 ng/L and 931-1 466 ng/L, respectively. The removal rates of SAs, FQs and MLs antibiotics reached 95.4%, 60.9% and 99.3% respectively after the leachate was treated by anaerobic-two-stage anoxic/aerobic biochemical treatment system. The biochemical treatment could effectively degrade SAs and MLs antibiotics, but the degradation performance of FQs antibiotics was poor. The removal rates of FQs antibiotics by sludge adsorption was between 7.6% and 17.7%, while the contents of SAs and MLs antibiotics in the sludge were both lower than 5%. The percentage of sludge adsorption contributed to antibiotic removal was relatively low. Antibiotics in leachate were mainly removed by biochemical treatment, and microbial degradation was the main mechanism of antibiotic removal in leachate treatment.
