- Title:
- Review and Analysis on the Characteristics and Rules of Virus in Urban Wastewater Treatment System
- Keywords:
- SARS-CoV-2; virus; wastewater treatment; virus removal
- 摘要:
- 根据新型冠状病毒的生物学特征，研究了病毒在水体中的赋存状态，分析总结了国内外污水处理中病毒的相关研究，认为污水处理厂只要保持正常稳定运行，就能够有效降低污水中病毒的浓度，可阻断肠道病毒和呼吸道病毒通过污水处理厂出水进行传播。对比分析了污水处理消毒过程中的臭氧消毒、氯消毒、紫外线消毒工艺，现有研究表明再生水处理过程的多级屏障作用可以有效去除病毒，结合工艺控制可以保障出水安全。此外，指出了污水处理工艺中可能产生气溶胶风险的位置，给出了相应的防护建议。这对新冠肺炎期间指导城镇污水处理厂安全稳定运行，防止新型冠状病毒进一步传播扩散有着重要参考意义。
- Abstract:
- Based on the biological characteristics of the novel coronavirus (SARS-CoV-2), the state of the virus in the water body was studied, and the related research of the virus in the wastewater treatment plant at home and abroad was summarized. The results indicated that the concentration of virus in the wastewater can be effectively reduced as long as the urban wastewater treatment facilities operate properly, and the transmission of enterovirus and respiratory viruses through effluent of wastewater treatment plant could be blocked. The disinfection effects of several disinfection methods in wastewater treatment such as ozone, chlorine and ultraviolet radiation were analyzed. The research showed the viruses in effluent of reclaimed water plant will be removed by the multistage treatment protection, and the combined process control could ensure the safety of the effluent. In addition, the possible location of aerosol risk in wastewater treatment process was pointed out, and corresponding protection suggestions were given. It has important reference significance for guiding the operation of urban wastewater treatment plants and preventing the further spread of novel coronavirus.
