Description
Technical Field
The utility model relates to an environmental waste handles the field, especially a medical waste treatment technical field.
Background
The main differences between medical waste and general household waste are: the medical waste has a large amount of pathogenic microorganisms and strong humus, and is easy to infect human bodies and pollute the environment. The primary task of medical waste treatment is therefore disinfection and inactivation. The current main sterilization techniques include high-temperature steam sterilization, chemical sterilization, microwave sterilization, irradiation sterilization, and the like.
(1) An autoclaving method belongs to a physical method, which is a process for killing pathogenic microorganisms in superheated steam. The sterilization effect of the medical waste sterilizing device mainly depends on the temperature, the steam contact time and the penetration degree of steam, but the medical waste is various and has large difference, so that the optimal sterilization effect cannot be achieved; toxic volatile organic compounds and waste liquid are easily generated in the treatment process, and all kinds of medical waste cannot be treated.
(2) The microwave sterilization method mainly depends on the heating effect of microwave on water and the microwave action of certain frequency and wavelength, and can kill most of microorganisms, but the sterilization effect is unstable. If metal products are mixed with the waste, the operation of the equipment is disturbed and even destroyed.
(3) The irradiation disinfection method has a wide range. At present, the most common mode is to disinfect the surface of an object by using ultraviolet rays, but the action range is only limited on the surface, and deep disinfection cannot be carried out. The radioactive cobalt source is adopted to generate gamma rays which can penetrate medical waste and have strong sterilization capability. However, the facility protection requirement is high, the investment is huge (more than 4000 ten thousand), the construction period is long (6-9 months), the maintenance is difficult, the risk of radioactive leakage exists, and few engineering cases for medical waste treatment exist.
(4) Chemical disinfection methods have a long history and wide application in disinfection and sterilization. The method comprises reacting the medical waste with a disinfectant (such as sodium hypochlorite, chlorine dioxide, peracetic acid, ethylene oxide) at a certain concentration, and ensuring sufficient contact area and contact time between the waste and the disinfectant, wherein the organic substances are decomposed and infectious germs are killed or inactivated during the disinfection process. But the method consumes chemical reagents and can not avoid secondary pollution.
Ozone (O)3) As a pre-oxidant, the oxidizing power is 2 times that of chlorine-containing disinfectants, and the sterilizing power is hundreds times that of the chlorine-containing disinfectants. Ozone as gas can permeate into the object to realize deep disinfection, so that the disinfection is more thorough; in addition, the ozone can be decomposed into oxygen and oxygen free radicals, secondary pollution and residues are avoided, the ozone can be mostly used for spraying and disinfecting hospital beds in hospitals, but ozone oxidation equipment for treating medical wastes in a large scale is less in product.
However, the form of medical waste disposal is not optimistic. The medical waste treatment center is generally established in a land-level administrative area, and the medical waste treatment rate is low according to medical waste incineration and non-incineration treatment modes. Generally, after medical wastes are collected and transported from hospitals, the medical wastes can only be sent to a factory with professional qualifications for incineration treatment without disinfection, and the treatment capability of a common garbage incineration plant cannot be utilized or the medical wastes cannot be subjected to landfill treatment. These problems not only affect the efficiency of waste disposal, but also carry the risk of microbial cross-contamination.
Therefore, it is very urgent to sterilize a large amount of medical wastes quickly, thoroughly and safely. The medical waste disinfection technology which can be directly treated in the hospital on the spot is urgently needed, is beneficial to building a distributed disinfection mode and relieves the pressure of the centralized collection and transportation of waste at present.
