抗生素废水是一类色度深、含盐量高、悬浮物多的高浓度有机废水，主要有磺胺类、四环素类、大环内酯类、喹诺酮类等，成分极其复杂，因此需要开发一种绿色安全高效的废水处理方式。半导体MgFe2O4作为一种软磁n型半导体材料，具有带隙较小，光吸收性能好，耐腐蚀性且对环境无害的特点，广泛应用于多相催化、热疗、光催化剂、金属离子去除、吸附、传感器、偶氮染料降解等领域。
Environment pollution by antibiotics raised notable attention.In this paper,ZIF-8,a metal-organic framework material,was proposed as a potential absorbent to remove doxycycline hydrochloride(DCH)from
The existence of antibiotics and heavy metal co-pollution has become a major environmental issue.In this study,the three three-dimensional biofilm-electrode reactors(3D-BERs)powered by 0.8V voltage we
本研究以洞庭湖流域为典型，通过调查典型污染源(畜牧养殖废物/废水和城镇污水)中抗生素的分布，建立了典型流域抗生素排放源清单，通过实际检测数据估算流域内抗生素排放因子和排放量.结果显示，畜牧养殖废物/废水和城镇污水是洞庭湖流域主要的抗生素排放湖，前者以四环素类抗生素为主，总排放因子达363 mg/d/猪；后者则以大环内酯类抗生素最高，总排放因子约36.4 mg/天/千人.
环境中残留的抗生素一直被认为与环境中抗性基因(antibiotic resistance genes,ARGs)产生与传播有着密切联系,目前,学者们对于环境中抗生素与ARGs关系研究较多,但研究结果却不尽相同.本研究用磺胺对大肠杆菌(Escherichia coli,E.coli)毒性作用表征磺胺的胁迫作用,用突变和接合转移表征ARGs的产生与传播,测定了5种磺胺对E.coli的毒性、突变与质粒接
Antibiotics are widely detected in the environment and pose a serious threat to aquatic life and human health.Constructed wetlands are widely used in the purification of low-pollution water bodies,and
Antibiotics are characterized by accumulation and refractory properties and are widely detected in the environment.
随着集约化、规模化畜禽养殖业的蓬勃发展，抗生素因在预防和治疗疾病、促进动物生长等方面发挥的显著作用而被广泛应用.用于动物的抗生素大约有50％-90％以母体形式通过粪便和尿液排出体外.H·lzel等在猪粪中检测到抗生素高达500 mg/L[1].
In past decades,antibiotics have attacked enormous attention due to frequent detection and potential environmental risk.
氟喹诺酮类药物(Fluoroquinolones,FQNs)在我国被广泛应用于人体临床和畜禽养殖业的疾病预防,其中环丙沙星、诺氟沙星、氧氟沙星三类约占国内氟喹诺酮类抗生素总产量的98％,且每年生产的氟喹诺酮类抗生素有一半是用于畜禽养殖。
