At present, the medical waste treatment methods include incineration, sanitary landfill, crushing and compression, chemical treatment, high-temperature sterilization, pyrolysis, microwave sterilization, plasma treatment and the like, and the main purpose of treatment is to make the medical waste harmless, reduce and recycle. The microwave sterilization method has the characteristics of good sterilization effect, wide sterilization spectrum, capability of killing various microorganisms, pathogens and the like, high sterilization efficiency, short sterilization time, good destroying and volume reducing effects, no secondary pollution and the like, and is one of the feasible technologies in the harmless treatment technology of medical wastes and the best feasible technical guideline for preventing and treating pollution in the treatment and disposal of medical wastes.

The contradiction between the difficult safe disposal of medical waste in remote areas and small and medium-sized health care hospitals and the strict requirements of medical waste storage and treatment is prominent. In addition, medical wastes generated in public health emergencies such as SARS, pneumonia, flu, avian flu and the like with high risk of infectivity are more dangerous because stacking, collecting and transporting also can increase the chance of infection. Thus, for medical waste disposal, the ecological environment department specifically requires that two "100%" must be implemented, i.e., 100% full coverage of environmental regulations and services for all medical institutions and facilities throughout the country; the medical waste and medical sewage can be effectively collected, transported, treated and treated in time by 100 percent, and the construction of medical waste treatment facilities is required to be comprehensively accelerated.
