Medical waste is divided into: infectious waste, pathological waste, injurious waste, pharmaceutical waste, chemical waste.
Treatment technology: medical waste treatment technology in China is still in the exploratory stage, the preferred method is still not mature enough. Relevant treatment technologies are broadly divided into three categories:
① high-temperature treatment methods, such as incineration, pyrolysis and vaporization;
② alternative treatment methods, such as chemical disinfection, high-temperature and high pressure steam sterilization, dry thermal disinfection, microwave treatment and safe landfill method;
③ innovative technologies, such as plasma technology, radiation technology. Used to deal with medical waste has been a variety of technologies, according to the different principles of treatment, generally can be divided into sterilization and disinfection method, incineration, plasma, pyrolysis and sanitary landfill method.

Hazard: medical waste occurs along with the process of medical services, such as improper disposal, arbitrary open piles, not only occupies a large amount of land, resulting in a reduction of available land resources, and a large number of toxic waste residues or waste liquids in the natural world everywhere in the circulation, it is easy to come into contact with the soil, and some medical and health organizations Even the medical waste will be simply buried, which is the pollution of the soil is very big.
Once the toxic substances of medical waste enter the soil, they will be adsorbed by the soil, pollute the soil, kill the microorganisms and protozoa in the soil, destroy the micro-ecology of the soil, and in turn reduce the soil's degradation of the pollutants; the acids, alkalis and salts in them will change the nature and structure of the soil, leading to the acidification, alkalization and hardening of the soil, and affecting the development and growth of the plant roots, destroying the ecological environment. and growth, destroying the ecological environment.
At the same time, many toxic organic substances and heavy metals will accumulate in the plant body, and after the human body inhales, it will cause serious damage to the liver and nervous system, induce cancer and make the fetus deformed.
