- 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:
- 根據(jù)新型冠狀病毒的生物學特征，研究了病毒在水體中的賦存狀態(tài)，分析總結了國內外污水處理中病毒的相關研究，認為污水處理廠只要保持正常穩(wěn)定運行，就能夠有效降低污水中病毒的濃度，可阻斷腸道病毒和呼吸道病毒通過污水處理廠出水進行傳播。對比分析了污水處理消毒過程中的臭氧消毒、氯消毒、紫外線消毒工藝，現(xiàn)有研究表明再生水處理過程的多級屏障作用可以有效去除病毒，結合工藝控制可以保障出水安全。此外，指出了污水處理工藝中可能產生氣溶膠風險的位置，給出了相應的防護建議。這對新冠肺炎期間指導城鎮(zhèn)污水處理廠安全穩(wěn)定運行，防止新型冠狀病毒進一步傳播擴散有著重要參考意義。
- 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.
