关于加强城市净水厂病毒去除与控制的工程优化设计措施

Optimization Design Measures for Virus Removal and Control in Urban Water Treatment Plants

2020初新冠肺炎疫情暴发后,人民对病毒防范意识上升到空前高度。COVID-19病毒以近距离飞沫和接触传播方式为主,同时研究发现,在新冠肺炎患者的粪便与尿液中均检测到了COVID-19病毒活体,COVID-19病毒被证实也可通过粪-口传播。人类和动物排泄物是饮用水微生物污染的主要途径[1],病原微生物的控制是饮用水安全保障的首要问题。本文结合现行水厂工艺的优化,就去除饮用水中粪口传播病毒进行探讨,以期为饮用水中病毒等微生物的去除和饮用水安全保障提供一定的参考。

After the outbreak of COVID-19 in early 2020,people's awareness of virus prevention has reached an unprecedented level.The transmission of COVID-19 virus is mainly through close droplets and contact.Meanwhile,studies have found that live COVID-19 virus can be detected in feces and urine of the infected patients.And it has been confirmed that COVID-19 virus can be transmitted through fecal-oral way.Excrement of human and animal are the primary pollution source of microbial contamination in drinking water[1],and the control of pathogenic microorganisms is the primary issue of drinking water safety.This article discusses the removal of fecal-oral spread viruses in drinking water,combined with the optimization of the current water plant process,in order to provide a certain reference for the removal of viruses and other microorganisms in drinking water and the security of drinking water..
