摘要

    传统的城市废水处理厂（UWTP）在消除大多数新出现的污染物（CEC）方面效率很差，这些污染物包括抗生素，抗药性细菌和抗药性基因（ARB和ARG）。这些污染物引起了大自然和人类健康的担忧，特别是如果将超污水处理厂的废水再用于农作物灌溉。传统的UWTP极有可能需要额外的高级处理阶段，才能满足废水回用的水质限制。最近，Rizzo及其同事[1]发表了一篇出色的评论，旨在提出潜在的先进治疗方案，尤其是在消除CEC和ARB和ARG方面。他们深入评估了用于废水处理的最佳可用技术（BAT）的性能，以减少CEC和ARB和ARG。尤其是，他们评估了臭氧氧化，活性炭吸附，化学消毒，紫外线辐射，高级氧化工艺（AOP）和膜过滤，重点是它们有效消除CEC，ARB和ARG的能力以及其优缺点。这项工作着重于涉及上述最佳可行技术的可能的治疗方案。如Rizzo等人的结论。 [1]一种先进的处理技术不足以减少化学CEC，ARB和ARG的释放并使废水更安全地用于农作物灌溉；但是，将它们无意识地集成在一起并需要一个适当的控制程序。没有奇迹般的最佳可行技术来处理农业用水中的废水。在每种情况下，建议对多种技术进行适当的组合。

    Traditional urban wastewater treatment plants (UWTPs) are badly efficient in eliminating most contaminants of emerging concern (CECs), comprising antibiotics, antibiotic-resistant bacteria and antibiotic resistance genes (ARB & ARGs). Such pollutants induce some worry for nature and human health, especially if UWTPs effluents are reused for crop irrigation. In all probability, traditional UWTPs will need extra advanced treatment stages to satisfy water quality limits for wastewater reuse. Recently, Rizzo and his co-workers [1] published an excellent review that aims to suggest potential advanced treatment solutions, especially concerning the elimination of CECs and ARB & ARGs. They deeply assessed the performance of the best available technologies (BATs) for domestic wastewater treatment to decrease CECs and ARB & ARGs. Especially, they evaluated ozonation, activated carbon adsorption, chemical disinfection, UV radiation, advanced oxidation processes (AOPs) and membrane filtration focusing on their capacity to efficiently eliminate CECs and ARB & ARGs, as well as their benefits and disadvantages. This work focuses on likely treatment trains involving the aforesaid BATs. As concluded by Rizzo et al. [1] a one advanced treatment technique is not enough to reduce the liberation of chemical CECs and ARB & ARGs and make wastewater reuse for crop irrigation safer; however, an impertinent integration of them and an appropriate controlling program would be needed. There is no miraculous BAT for treating wastewater for water reuse in agriculture. An appropriate combination of many techniques would be suggested following each case.
