The COVID-19 has been declared a pandemic by the World Health Organization. Along with impairing the respiratory system, it also affects the gastrointestinal system. By reviewing experiments on the wastewater analysis for the detection of coronavirus, this study explores the fate, persistence, and various remediation strategies for the virus removal from the wastewater. The results indicated that the virus can be detected in the wastewater samples, feces, and sewage, even before the onset of symptoms. Coronavirus can be a potential panzootic disease, as several mammalian species get infected by the deadly virus. The disinfection strategies used earlier for the treatment of wastewater are not sufficient for the removal of viruses from the wastewater. Therefore, concerted efforts should be made to understand their fate, sources, and occurrence in the environmental matrices. To prevent the spread of the panzootic disease, revised guidelines should be issued for the remediation of the virus. Recent viral remediation methods such as membrane bioreactors and advanced oxidation methods can be used. Therefore, the present review puts a light on the current knowledge on the occurrence of coronaviruses in wastewater, the possible sources, fate, and removal strategies.
新型冠状病毒肺炎已被世界卫生组织宣布为大流行病。它除了损害呼吸系统外，还会影响胃肠道系统。通过回顾关于废水分析以检测冠状病毒的实验，本研究探讨了病毒在废水中的归宿、持久性以及从废水中去除病毒的各种修复策略。结果表明，甚至在症状出现之前，就可以在废水样本、粪便和污水中检测到病毒。冠状病毒可能是一种潜在的动物流行病，因为几种哺乳动物物种会感染这种致命病毒。早期用于处理废水的消毒策略不足以从废水中去除病毒。因此，应共同努力了解它们在环境基质中的归宿、来源和存在情况。为防止动物流行病的传播，应发布修订后的病毒修复指南。可以使用最近的病毒修复方法，如膜生物反应器和高级氧化法。因此，本综述揭示了目前关于冠状病毒在废水中的存在情况、可能的来源、归宿和去除策略的知识。
