【摘要】：为了有效控制猪场废水排放的兽用抗生素对生态环境的污染,研究在猪场建立废水收集、过滤系统,通过臭氧净化技术降解处理猪场废水中残留的兽用抗生素,在北京地区的5家猪场,对废水中SMD、SMM、SMX、CIP、NOR、OTC、DOX 7种兽用抗生素含量进行调查。结果表明:净化前7种兽用抗生素平均含量分别为3.341,2.576,1.398,4.915,3.709,5.846,8.224μg/L;以7.8 mg/L臭氧水净化处理20 min后,7种兽用抗生素平均含量分别为0.113,0.067,0.084,0.103,0.101,0.225,0.337μg/L,降解效率分别达到97.50%、97.59%、97.61%、97.75%、97.55%、96.06%和95.93%。臭氧净化技术对磺胺类、喹诺酮类抗生素的降解效率极显著高于四环素类抗生素(P0.01)。说明以臭氧净化技术治理猪场废水兽用抗生素残留效果显著。
[Abstract]:In order to effectively control the ecological environment pollution caused by veterinary antibiotics discharged from pig farm wastewater, the waste water collection and filtration system was established in the pig farm, and the residual veterinary antibiotics in pig farm wastewater were degraded by ozone purification technology. In five pig farms in Beijing, The contents of seven kinds of veterinary antibiotics in wastewater were investigated. The results showed that the average contents of seven kinds of animal antibiotics before purification were 3.3412.576N 1.3984.9158N 5.709N 5.846.68.224 渭 g / L, and the average contents of seven kinds of veterinary antibiotics were 0.1130.0677nr80.1030.1030.1030.1030.1030.2255渭 g / L, respectively, after being purified by 7.8 mg/L ozone water for 20 min, the average content of seven kinds of veterinary antibiotics was 0.1130.067an80.1030.103n 0.101g / L, 0.2255渭 g / L, respectively. The degradation efficiency reached 97.50% and 97.59% respectively. The amount of 97.65% and 97.75% was 96.06% and 95.93%, respectively. The degradation efficiency of quinolones was significantly higher than that of tetracycline antibiotics (P 0.01).
