摘要:

按照新型冠状病毒的生物学特点，研究了病毒在水体中的赋存状况，阐发总结了国表里污水处置中病毒的相干研究，认为污水处置厂只需连结一般不变运转，就可以够有用下降污水中病毒的浓度，可阻断肠道病毒和呼吸道病毒经由过程污水处置厂出水进行传布。对照阐发了污水处置消毒进程中的臭氧消毒、氯消毒、紫外线消毒工艺，现有研究注解再生水处置进程的多级樊篱感化能够有用去除病毒，连系工艺节制能够保障出水平安。另外，指出了污水处置工艺中可能发生气溶胶风险的位置，给出了响应的防护建议。这对新冠肺炎时代指点城镇污水处置厂平安不变运转，避免新型冠状病毒进一步传布分散有侧重要参考意义。

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.
