摘要:

抗生素抗性基因(antibiotic resistance genes,ARGs)被世界卫生组织确定为目前严重的卫生问题之一,环境中的ARGs污染会导致产生“超级细菌”,对人类和生物的健康造成了巨大威胁。因此本文系统描述了ARGs的危害及其在环境中扩散机制,综述了ARGs在地表水、地下水、土壤中的污染情况及在污水处理中的现状。分析表明,ARGs的传播机制中起关键作用的是水平基因转移;地表水中ARGs污染问题较其他水资源更为严重,且进一步引起了土壤ARGs污染并危害人体健康;就污水处理系统的处理现状进行分析,尽管对ARGs去除效果最好的是高级氧化工艺,但膜生物反应器(membrane bio-reactor, MBR)凭借着其成本较低、经济效应好且处理效果较传统活性污泥工艺好的优点,有更好的应用前景。因此,结合现有工艺构建组合工艺成为了未来污水处理厂提标改造的方向。

Abstract:

Antibiotic resistance genes (ARGs) have been identified by the World Health Organization (WHO) as one of the serious health problems, and the contamination of ARGs in the environment can lead to the emergence of“superbugs”, which poses a great threat to the health of human beings and organisms. Therefore, this paper systematically described the hazards of ARGs and their diffusion mechanism in the environment, and summarized the contamination of ARGs in surface water, groundwater, soil and the current situation of wastewater treatment. The analysis showed that horizontal gene transfer played a key role in the spreading mechanism of ARGs. The pollution of ARGs in surface water was more serious than that of other water resources, and further caused the pollution of ARGs in soil and jeopardized the health of human beings. The current status of wastewater treatment system was analyzed, and although the advanced oxidation process is the best process for the removal of ARGs, the membrane bio-reactor (MBR) is more effective for removing the ARGs by virtue of its lower cost and good economic effect. Although the best removal effect of ARGs is the advanced oxidation process, the MBR has a better application prospect by virtue of its lower cost, good economic effect, and better treatment effect than the traditional activated sludge process. Therefore, combining the existing process and constructing a combined process has become the direction of future upgrading of wastewater treatment plants.

Key words: antibiotic resistance genes (ARGs), horizontal gene transfer, environmental pollution, sewage treatment
