Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an anti-infection closed type hospital sewage pretreatment equipment. Background technique [0002] With the continuous improvement of people's living standards, my country's medical industry has developed rapidly, and the number and scale of hospital construction have been rapidly expanded, especially the in-depth implementation of urban medical insurance and rural cooperative medical care systems. The pollution of medical sewage can not be ignored. The source and composition of hospital sewage are complex and harmful. Sewage contains a large number of pathogenic bacteria, viruses and chemical agents, which has the potential to cause space pollution and acute infection. and latent infection characteristics, the existing hospital sewage treatment process mostly adopts a non-closed form in the pretreatment stage, and some pathogenic microorganisms are easy to discharge with...

Problems solved by technology

[0002] With the continuous improvement of people's living standards, my country's medical industry has developed rapidly, and the number and scale of hospital construction have been rapidly expanded, especially the in-depth implementation of urban medical insurance and rural cooperative medical care systems. The pollution of medical sewage can not be ignored. The source and composition of hospital sewage are complex and harmful. Sewage contains a large number of pathogenic bacteria, viruses and chemical agents, which has the potential to cause space pollution and acute infection. and latent infection characteristics, the existing hospital sewage treatment process mostly adopts a non-closed form in the pretreatment stage, and some pathogenic microorganisms are easy to discharge with water or expand in air, which opens another channel for the spread of infectious diseases and endangers the health of personnel. An anti-infection closed sewage pretreatment equipment applied to hospital sewage treatment is very necessary
