A novel coronavirus (SARS-CoV-2) causing corona virus disease 2019 (COVID-19) has attracted global attention due to its highly infectious and pathogenic properties. Most of current studies focus on aerosols released from infected individuals, but the presence of SARS-CoV-2 in wastewater also should be examined. In this review, we used bibliometrics to statistically evaluate the importance of water-related issues in the context of COVID-19. The results show that the levels and transmission possibilities of SARS-CoV-2 in wastewater are the main concerns, followed by potential secondary pollution by the intensive use of disinfectants, sludge disposal, and the personal safety of workers. The presence of SARS-CoV-2 in wastewater requires more attention during the COVID-19 pandemic. Thus, the most effective techniques, i.e., wastewater-based epidemiology and quantitative microbial risk assessment, for virus surveillance in wastewater are systematically analyzed. We further explicitly review and analyze the successful operation of a sewage treatment plant in Huoshenshan Hospital in China as an example and reference for other sewage treatment systems to properly ensure discharge safety and tackle the COVID-19 pandemic. This review offers deeper insight into the prevention and control of SARS-CoV-2 and similar viruses in the post-COVID-19 era from a wastewater perspective.
一种导致2019冠状病毒病（COVID-19）的新型冠状病毒（严重急性呼吸综合征冠状病毒2）因其高度传染性和致病性而引起了全球关注。目前大多数研究集中在受感染个体释放的气溶胶上，但也应检测废水中严重急性呼吸综合征冠状病毒2的存在情况。在本综述中，我们使用文献计量学方法对COVID-19背景下与水相关问题的重要性进行了统计评估。结果表明，废水中严重急性呼吸综合征冠状病毒2的水平和传播可能性是主要关注点，其次是消毒剂大量使用造成的潜在二次污染、污泥处置以及工人的人身安全。在COVID-19大流行期间，废水中严重急性呼吸综合征冠状病毒2的存在需要更多关注。因此，系统分析了用于废水病毒监测的最有效技术，即基于废水的流行病学和定量微生物风险评估。我们进一步以中国火神山医院污水处理厂的成功运营为例进行明确的综述和分析，为其他污水处理系统妥善确保排放安全和应对COVID-19大流行提供参考。本综述从废水角度对COVID-19后时代严重急性呼吸综合征冠状病毒2及类似病毒的预防和控制提供了更深入的见解。
