Description
Technical Field

Background
At present, hospital waste water has complex sources and components and great harmfulness, and the scientific treatment of medical waste, particularly waste water, causes high attention. The medical wastewater mainly comprises sewage discharged from places such as hospital institutions, reagent rooms, bathrooms, toilets and the like, contains pollutants such as various medicines, disinfectants and the like, also contains a large amount of harmful organisms such as viruses, pathogenic bacteria and the like, and has more complex components. How to conveniently, quickly, effectively and safely treat medical wastewater according to local conditions, ensure that secondary pollution does not occur and prevent viruses from spreading through sewage is a problem which is urgently needed to be solved at present.
The hospital sewage contains a large amount of microbes such as bacteria and viruses, has the risks of space pollution, acute transmission and latent infection, and is a weak link of water pollution prevention and treatment work in China for a long time. In theory, any excreting pathogenic bacteria and viruses with infectious ability may cause disease problems such as infectious diseases if not properly treated. Of course, in conventional disinfection regimes, high doses of chlorine agents are effective in the disinfection of pathogens and viruses, but under such conditions, a large number of carcinogenic disinfection by-products may be produced. In addition, chlorine gas can also have an adverse effect on other organisms in the water body.
Radiation technology has strong penetrating power to initiate free radical reaction, and is widely applied to disinfection of food, medical supplies and other substances. Compared with the traditional chemical sterilization method, the irradiation technology sterilization has the advantages of high sterilization efficiency, safe operation, no environmental pollution, no residue, no analysis period and the like. Thus, the radiation technique should also be applicable to disinfection of contaminated water. Researches in recent years show that high-energy electron beams or Co60 sources can effectively kill viruses and other harmful substances in water bodies by performing irradiation disinfection treatment on sewage. Moreover, the irradiation technology is adopted to treat the sewage, so that the problem of secondary pollution caused by the traditional disinfection method (such as a chlorine disinfection method) can not be generated. In addition, compared with Co60, the high-energy electron beam has no radioactive source and can be started and closed quickly, which is more beneficial to large-scale sewage treatment.
