Distribution and Determination Method and Risk Assessment of Typical Enteroviruses in WWTPs
The determination of the COVID-19 in feces and wastewater threatens the global economy and public health,indicating the possibility of fecal-oral transmission.The wastewater in the urban wastewater treatment plants(WWTPs)comes from a wide range of sources and is an important way for water to transmit viruses.In order to further carry out relevant research work on viruses in wastewater treatment facilities,the quantitative distribution status of typical enteroviruses in WWTPs is analyzed,the inactivation mechanism of viruses in wastewater treatment processes and the research progress of enteroviruses in WWTPs at home and abroad is summarized.In addition,the concentration and determination methods of typical enteroviruses in WWTPs samples are combed,and the concentration of viruses in wastewater,infection probability and potential health risks are discussed by combining with quantitative microorganisms risk assessment(QMRA).It provides reference and theoretical support for the realization of the whole-process risk management of enterovirus in WWTPs and the formulation of subsequent treatment and disposal specifications.
