Description
Hazards of medical waste
- Medical waste contains a large number of infectious bacteria and viruses and other pathogenic microorganisms, which are infectious and can cause diseases or harm.
- If medical waste is piled arbitrarily in the open, it will not only occupy a large amount of land, leading to the reduction of available land resources, but also a large amount of toxic waste residue or waste liquid is exiled everywhere in nature, which is easy to contact the soil and cause soil pollution.
3, medical waste will be polluted water through various channels, such as with the surface runoff into rivers and lakes, or migrate into the water with the wind, especially when the medical waste in the open air place when deposited in the open air or mixed life waste, hazardous substances under the effect of rain, it is easy to flow into the rivers and lakes, causing serious pollution and destruction of water.
- In the process of stacking medical waste, under the action of temperature and moisture, some organic substances decompose and produce harmful gases, causing air pollution.
Treatment of medical waste
1、High pressure steam sterilization treatment
High-pressure steam sterilization treatment is in a sealed autoclave with steam at 134℃, so that the internal pressure of 210kPa is generated. Medical waste stays in the autoclave being 9:28 for 45 minutes, which is fully penetrated to ensure that pathogenic organisms are destroyed. The new generation of autoclave sterilization technology includes impregnation or grinding to ensure that the steam better penetrates the medical waste, resulting in better treatment results. High temperature steam sterilization treatment is a simple, feasible, economical, reliable, fast and safe sterilization method. After sterilization treatment, medical waste can be used as the same as ordinary household waste for sanitary landfill.
2、Incineration
Incineration treatment is a high temperature oxidation treatment process. Within the incinerator furnace, medical wastes by around 1000 ℃ high temperature burning, can put the waste of fuel oxidation basically into carbon dioxide, water and ash, and achieved the disinfection sterilization and remove most of the pollutants, the purpose of the chemical active ingredient by oxidative, leaving inorganic components generated slag discharge, In this process, the volume of medical waste is reduced, its perishable nature is fully changed, and the residue from incineration is easily disposed of. Generally speaking, the incineration of medical waste will undergo dehydration, degassing, ignition, combustion, flameout and other steps. The core of incineration treatment technology is the reasonable organization of combustion and the prevention and control of secondary pollution.
- Chemical disinfection treatment
Chemical disinfection treatment is suitable for the treatment of some liquid wastes in medical institutions, such as human blood, body fluids, feces, urine, etc., especially during the epidemic of infectious diseases, the disposal of feces of infectious diseases is more effective; It is not suitable to handle pathological waste. When sterilizing solid medical waste, the waste to be disinfected must be broken up first.
4, Microwave disinfection treatment
Microwave thermal effect sterilization treatment core technology is the use of microwave thermal effect and non-thermal effect to kill bacteria, microwave refers to the frequency of 300 MHZ electromagnetic wave.
Sterilization Chamber
○ Strictly according to the “pressure vessel”, “Fixed Pressure vessel safety technical supervision regulations” design, manufacturing and inspection regulations.
○ Cylindrical structure, the inner chamber is made of stainless steel, improve the durability of the equipment and the overall space utilization rate.
○ Door sealing adopts compressed air active sealing technology, set up upper door and side door structure, realize the safe isolation of sterilized medical waste and unsterilized medical waste, and avoid cross infection.
The outer surface of the main body is wrapped with high quality insulation material and coated with stainless steel wire drawing plate to ensure beautiful and clean.
2、Crusher
Crusher is mainly used for crushing medical waste. The equipment is driven by 42CrMo material with high strength and heavy load, and equipped with 55SiCr rotary cutting tool. It can effectively cut and break medical waste through two axes staggered installation tool rotating towards each other. The crushing of the material is the comprehensive action of various stresses of the crusher, and also accompanied by the extrusion action of the fixed blade installed along the frame of the crusher.
The equipment has the characteristics of high crushing efficiency, low maintenance cost, long tool life, low noise and dust, simple disassembly and assembly, convenient tool repair or replacement, current detection and thermal relay protection. It can fully meet the working environment with complex composition and poor working conditions of all kinds of medical waste, and has excellent crushing effect on soft materials such as gauze or hard metal materials such as surgical instruments. At the same time, the device has the function of working timer and overload protection, which can accurately display the working time and safe operation of the device.
