Description
Technical field
The present invention relates to a kind of processing method for carrying out sorting and recycling again after sterilizing resolution to medical waste.
Background technology
Medical waste carries many germs, if processing is bad, can pollute air, water source and soil, and can pass
Various infectious diseases are broadcast, jeopardize the health of people.Therefore, it is to be related to environmental sanitation and mankind's body to handle medical waste well
Body health and a key subjects of economic development.At present, the most of method using burning of processing to medical waste is entered
OK.Medical waste is handled in this way, can reach relatively good effect, but incinerator is complicated, and
Investment is big, and operating cost is higher, or even can also produce the harmful exhausts such as Han bioxin and harmful dust and slag.These harmful exhausts
And lime-ash, once being discharged into air and the environment of surrounding, serious secondary pollution will be caused to the environment of air and surrounding.
Therefore, burning disposal is carried out to medical waste, often also needed to using complicated flue gas purification system to flue gas caused by burning
Purified treatment is carried out, and landfill disposal is carried out to caused heavy metal lime-ash after burning, prevents the useful resource in part from reclaiming
Utilize.
The content of the invention
It is existing single to treatment of!medical waste method in order to improve, it is also easy to produce secondary pollution and can not be by medical waste
In the actual conditions such as useful resource recycling, it is an object of the invention to provide a kind of technique is simple, secondary dirt will not be produced
Dye, treatment of!medical waste minimizing can be reached, the medical waste resolution processing that innoxious and part utility recycles
Method.
Medical waste decomposing treatment method proposed by the present invention, mainly including following key step：
(1) medical waste is sent into digestion instrument, adds oxidation bactericidal agent and conditioner, then carried out in digestion instrument
Heating, the sterilizing resolution processing of pressurization, the temperature of sterilizing resolution processing is 150-280 DEG C, pressure 0.2-1.2MPa, the time
For 30-120 minutes, reach medical waste minimizing, innoxious degree.
(2) sterilize after resolution processing, open the discharge gate of digestion instrument, under the conditions of normal pressure or certain pressure, will go out
Residue after bacterium resolution is discharged from digestion instrument and carries out sorting process.
Sorting process described in the present invention be the residues such as waste plastics, needle tubing are crushed, ruin type, magnetic separation after reclaim
Utilize, burning disposal is made by plain cylindrical furnace to residues such as cotton, rag, gauzes or makees landfill disposal, to useless after resolution
Liquid, make reclaimed water afterwards after testing and recycle or be discharged into waste pipe；Described heating, input saturated steam is pressurised into, or
Using the electric heater unit of digestion instrument itself while saturated steam is inputted, or individually use digestion instrument itself
Electric heater unit carry out；Described oxidation bactericidal agent is ozone, ClO2, hydrogen peroxide, potassium permanganate, sodium peroxide, persulfuric acid
Salt；Described conditioner is pulverized limestone, zeolite, diatomite, dolomite.
It is proposed by the present invention that oxidation bactericidal agent is added in digestion instrument, it is therefore an objective to accelerate medical waste sterilizing and resolution
Speed, the purpose for adding conditioner be adjust rubbish pH value, eliminate organic matter in garbage caused by foul gas.
The present invention is compared with burning method with advantages below：
First, the effect of sterilizing resolution is good, innoxious, minimizing the purpose for the treatment of of!medical waste is reached.Using above-mentioned skill
Art scheme, medical waste is subjected to oxidation sterilization treatment under high-temperature and high-pressure conditions, can thoroughly clear up such as body material, bone
The organic matter such as head and purulence blood, kills all bacteriums and virus, removes stink peculiar smell, reaches the degree of medical waste minimizing
More than 70%.
Two, which are advantageous for the moieties after handling resolution, recycles, especially some plastics, metal systems
Product, recycled after sterilizing resolution processing, reduce the pollution to environment.
Third, technique is simple, easy to operate, the cost of processing is very low.Particularly medical waste can be collected at any time, with
When clear up sterilization treatment, it is economical and practical, be easy to the popularization and application in small and medium-sized cities.
Embodiment
