Problems solved by technology

Using this method to treat medical waste can achieve relatively good results, but the structure of the incineration device is complicated, and the investment is large, the operating cost is relatively high, and even harmful waste gas and harmful ash containing dioxins will be produced.
Once these harmful exhaust gases and ash are discharged into the atmosphere and the surrounding environment, they will cause serious secondary pollution to the air and the surrounding environment.
Therefore, when incinerating medical waste, it is often necessary to use a complex flue gas purification system to purify the flue gas generated by incineration, and to landfill the heavy metal ash generated after incineration, so that some useful resources cannot be recycled. use
More importantly, in the vast small and medium-sized cities in my country, it is difficult to build waste incineration plants with large investment and high processing costs. The method of relying on incineration to treat medical waste is not completely suitable for the actual situation of small and medium-sized cities in my country.

Embodiment 1

[0015] Send mixed medical waste such as hospital beds and operations into the digestion device, add oxidative sterilizer hydrogen peroxide and conditioner lime powder at the same time, and then input saturated water vapor into the digestion device for heating and pressure treatment. The temperature in the digestion device is controlled at 250° C., the pressure is controlled at 0.9 MPa, and the digestion time is 60 minutes. After the sterilization and digestion treatment, the discharge port of the digestion device is opened, and the medical waste residue after sterilization and digestion is discharged under normal pressure for sorting treatment. It is to incinerate the sterilized and digested cotton, rags, gauze and other residues in ordinary boilers for reduction and harmless treatment.

Embodiment 2

[0017] Send the pre-sorted medical waste including injection products such as plastic products and needle tubes into the digestion device, and add the oxidative sterilizer ClO at the same time 2 and conditioning agent diatomaceous earth, and then input saturated steam into the digestion device for heating and pressure treatment. The temperature in the digestion device is controlled at 200° C., the pressure is controlled at 0.7 MPa, and the digestion time is 90 minutes. After the sterilization and digestion treatment, the discharge port of the digestion device is opened, and the medical waste residue after sterilization and digestion is sorted. It is to crush, destroy, magnetically separate plastic products and needle tubes, and recycle them to achieve the reduction and harmless treatment of medical waste.

Embodiment 3

[0019] Send the mixed medical waste and medical wastewater into the digestion device together, add the oxidizing sterilant ozone gas and the conditioning agent lime powder at the same time, then input saturated water vapor into the digestion device and use the electric heating device of the digestion device for comprehensive processing Temperature and pressure treatment. The temperature in the digestion device is controlled at 150° C., the pressure is controlled at 0.5 MPa, and the digestion time is 120 minutes. After the sterilization and digestion treatment, open the discharge port of the digestion device, discharge the material under the pressure of 0.1MPa, and carry out corresponding treatments such as incineration, landfill and recycling for all kinds of residual substances after sorting.

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

Technical field [0001] The invention relates to the technical field of environmental sanitation, in particular to a treatment method for sterilizing and degrading medical waste, sorting and recycling it. Background technique [0002] Medical waste contains a lot of germs. If it is not handled properly, it will pollute the air, water and soil, and can spread various infectious diseases, endangering people's health. Therefore, how to deal with medical waste is a major issue related to environmental sanitation, human health and economic development. At present, most of the treatment of medical waste is carried out by incineration. Using this method to treat medical waste can achieve better results, but the structure of the incineration device is complicated, and the investment is large, the operating cost is relatively high, and even harmful waste gas and harmful ash containing dioxins will be produced. Once these harmful exhaust gases and ash are discharged into the atmosphe...
