摘要
      废水处理设施中新出现的抗生素抗性基因（ARGs）等污染物的威胁越来越受到关注。基于现有的污水处理工艺，特别是在生物处理装置中，如何同时有效地去除传统污染物和ARGs是非常重要的。我们注意到，ARGs减少的驱动因素与控制短程硝化和反硝化的驱动因素（如pH、游离氨（FA）和游离亚硝酸（FNA））高度重叠。这一点通过实验室规模和中试规模的测试得到了统计证实。在此基础上，我们提出短程硝化和反硝化可以是一种潜在的方法，有效且经济地减少ARGs和传统污染物。这一创新概念可能为减少ARGs提供新的机会，并可能翻新现有污水处理厂的现有技术地图。
Abstract
The threats of emerging pollutants like antibiotic resistance genes (ARGs) in wastewater utilities are gaining growing attention. Based on the existing wastewater treatment process (WWTPs), especially in the biological treatment units, how to remove conventional pollutants and ARGs simultaneously and efficiently is very important. We noted that driving factors of ARGs reduction highly overlaps with that controlling shortcut nitrification and denitrification (e.g., pH, free ammonia (FA), and free nitrous acid (FNA)). This was statistically confirmed by a lab-scale and pilot-scale test. On this basis, we then propose shortcut nitrification and denitrification can be a potential approach, reducing ARGs and conventional contaminants efficiently and economically. This innovative concept may provide new opportunities for ARGs reduction, and possibly renovate the present tech-map of existing wastewater treatment plants (WWTPs).
