Abstract
The invention provides a decomposing treatment method for medical garbage which which mainly comprises the following steps, first, loading the medical garbage into a degradation apparatus, charging oxygenizing bactericidal agent and amendment, then carrying out warming, pressurizing germicidal treatment at the temperature of 150-280 deg. C, the pressure of 0.2-1.2 MPa, finally opening the discharge port of the degradation apparatus, so as to discharge the residue out of the degradation apparatus for sorting treatment.
Description
Affiliated technical field
The present invention relates to the environmental health technical field, specifically a kind of to medical waste sterilize clear up after sorting and the processing method recycled again.
Background technology
Medical waste has a lot of pathogenic bacterias, if handle bad, can contaminated air, water source and soil, and can propagate various infectious disease, jeopardize the healthy of people.Therefore, handling medical waste well is key subjects that are related to environmental health and human body health and economic development.At present, the most of method of burning that adopts of the processing of medical waste is carried out.Adopt this method to handle medical waste, can reach reasonable effect, but the complex structure of incinerator, and investment is big, operating cost is than higher, even also can produce harmful exhausts such as containing bioxin and harmful lime-ash.These harmful exhausts and lime-ash in case enter in atmosphere and the environment on every side, will cause serious secondary pollution to air and environment on every side.Therefore, medical waste is carried out burning disposal, need adopt complicated flue gas purification system to carry out purified treatment toward contact, and the heavy metal lime-ash that produces after burning is carried out landfill disposal, the part useful resource can not be recycled burning the flue gas that produces.Main is that it is big to be difficult to set up investment in the vast small and medium-sized cities of present China, the garbage burning factory that disposal cost is high, and the method for dependence burning disposal medical waste not exclusively is fit to the practical situation of China small and medium-sized cities.
Summary of the invention
Existing single in order to improve to the medical waste processing method, easily produce secondary pollution and can not be with practical situations such as useful resource recyclings in the medical waste, it is simple to the purpose of this invention is to provide a kind of technology, can not produce secondary pollution, can reach that medical waste is handled minimizing, medical waste innoxious and that the part utility is recycled is cleared up processing method.
The medical waste that the present invention proposes is cleared up processing method, mainly comprises following key step:
(1) medical waste is sent in the digestion instrument, add oxidation biocide and conditioner, processing is cleared up in the sterilization of heating in digestion instrument then, pressurizeing, the temperature that processing is cleared up in sterilization is 150-280 ℃, pressure is 0.2-1.2MPa, time is 30-120 minute, reaches medical waste minimizing, innoxious degree.
(2) sterilization is cleared up after the processing, opens the discharge gate of digestion instrument, and under normal pressure or certain pressure condition, the residue after sterilization cleared up is discharged from digestion instrument and carried out sorting process.
The said sorting process of the present invention is to recycle after type, magnetic separation are pulverized, ruined to residues such as waste plastics, needle tubing, residues such as Cotton Gossypii, rag, gauze are made burning disposal or made landfill disposal by plain cylindrical furnace, to the waste liquid after clearing up, waste pipe is recycled or entered to water during the back was done after testing; Saidly heat, be pressurised into the input saturated steam, perhaps in the input saturated steam, adopt the electric heater unit of digestion instrument self, perhaps adopt the electric heater unit of digestion instrument self to carry out separately; Said oxidation biocide is ozone, ClO
2, hydrogen peroxide, potassium permanganate, sodium peroxide, persulfate; Said conditioner is pulverized limestone, zeolite, kieselguhr, dolomite.
The adding oxidation biocide in digestion instrument that the present invention proposes, purpose is the speed of accelerating the medical waste sterilization and clearing up, the purpose that adds conditioner is to adjust the pH value of rubbish, the foul gas that Organic substance produces in the elimination rubbish.
The present invention compares with burning method and has the following advantages:
The one, it is effective that sterilization is cleared up, the purpose of innoxious, the minimizing that has reached that medical waste handles.Adopt technique scheme, medical waste is carried out the oxidation sterilization treatment under high-temperature and high-pressure conditions, can thoroughly clear up, kill all antibacterials and virus such as Organic substances such as human body material, bone and pus and blood, remove the stink abnormal flavour, the degree of medical waste minimizing is reached more than 70%.
The 2nd, help the part material of clearing up after the processing is recycled, especially some plastics, metallic article, sterilization is recycled after clearing up and handling, and has reduced the pollution to environment.
The 3rd, technology is simple, and is easy to operate, and the cost of processing is very low.Particularly can collect at any time, clear up sterilization treatment at any time medical waste, economical and practical, be easy in small and medium-sized cities, apply.
The specific embodiment
Describe the present invention below by embodiment.
