Multi-level green barrier disinfection system blocks the "material transmission" of the new coronavirus

Science and Technology Daily (Reporter Li Liyun) The team of Academician Ma Jun of the Harbin Institute of Technology School of Environment recently published a report entitled "Challenges of Global Spread of New Coronavirus Cold Chain Logistics and Multi-level Green Barrier Epidemic Prevention and Control Countermeasures" in the journal "Engineering" of the Chinese Academy of Engineering.

As the low temperature environment is conducive to the long-term survival of the virus, the "material-to-person" transmission method of infection through contact with contaminated cold chain goods may play a key role in the occurrence and transmission of the new crown pneumonia epidemic

In order to effectively cut off the "material-to-person" transmission of the new coronavirus through cold chain logistics, the Ma Jun team proposed a multi-level green barrier disinfection system that covers the entire life cycle of cold chain goods

In response to common disinfectants such as sodium hypochlorite, peracetic acid, and chlorine dioxide, the disinfection efficiency is greatly reduced due to icing, and the disinfection dead corners caused by the accumulation of cold chain goods in cold storage and containers, the Ma Jun team proposed to adopt The gaseous disinfectant represented by ozone has the advantages of high automation of disinfection equipment, no dead corners of disinfection, and good low-temperature disinfection effect.

The advanced ozone oxidation technology developed by his team has been applied in the actual disinfection operations of cold chain logistics in Dalian, Suifenhe and other places
