And

First, the lid 10d provided in the processing tank 10 provided with the stirring device and the temperature detecting means is opened, and infectious organic waste such as gauze, absorbent cotton and the like and the organic waste are injected into the inlet 10e. At this time, the inputted infectious organic waste such as gauze and absorbent cotton and the organic waste are cut into an appropriate size by the cutter 11. The cut infectious organic waste and organic waste are discharged from the discharge port 11 a of the cutter 11 and accumulate in the processing tank 10. If the amount of infectious organic waste and organic waste to be treated is large, the cutter 1
Those cut separately may be directly put into the processing tank 10 without going through the processing tank 1.

On the other hand, in the case of liquid infectious organic waste such as waste blood, for example, in the case of waste blood, the tube 41 connected to the blood transfusion bag 40 is inserted into the insertion port 15a of the receiving port 15. Then, insert the slide cover 15b into the insertion port 15
The processing tank 10 is moved so as to cover the periphery of the vicinity of the connection between the a and the tube 41 to prevent leakage when storing the waste blood or the like in the processing tank 10. At this time, the mixture of the infectious organic waste and the organic waste is charged at a ratio such that the total water content is 30 to 60%, and the water content is adjusted (S1). 30-60% total water content of infectious organic waste and organic waste
The reason for this is to make the progress of the fermentation treatment by the microorganisms smooth. When the fermentation treatment is carried out with the water content adjusted to about 50% to 60%, a fluid and smooth treated product can be obtained, so that subsequent handling becomes extremely easy.

The infectious organic waste and the organic waste contained in the processing tank 10 are stirred by the cutter blade 14 while rotating the rotating shaft 12 by the motor 21 to mix the contents so that the contents become uniform (S2). ). As described above, the rotating shaft 12
A large number of cutter blades 14 are arranged at intervals in the height direction. By rotating the rotating shaft 12, the infectious organic waste and the organic waste are stirred and mixed, and the infectious organic waste is mixed. The waste and organic waste are cut further finely and homogenized.

Next, the infectious organic waste and the organic waste are mixed, and a fermentation promoter seeded with microorganisms is added to a mixture whose total water content is adjusted to 30 to 60%. The fermentation treatment is carried out by rotating so that the mixture of the infectious organic waste and the organic waste and the fermentation accelerator are uniformly mixed (S3). Control panel 17 during fermentation process
Receives signals from a number of temperature sensors 16 and performs appropriate control so that the fermentation process proceeds uniformly while rotating the rotating shaft 12 so as to meet preset conditions and stirring appropriately.

In the fermentation step, the temperature of the mixture of the infectious organic waste and the organic waste increases because the fermentation heat is gradually generated as the fermentation proceeds. The temperature of the mixture of infectious organic waste and organic waste is raised to 80 degrees Celsius by fermentation heat generated during fermentation by microorganisms. As a result, a human infectious virus and bacteria are sterilized. When the fermentation is completed, the fermented product is used as compost. Thus, the infectious organic waste can be recycled, and the goodwill of the blood donor is not wasted. In addition, since microorganisms are propagated in the fermentation treatment product, this can be used as a fermentation accelerator. Specifically, a fermentation treatment is added to a mixture of the infectious organic waste to be treated and the organic waste as a fermentation promoter to perform a fermentation treatment of the infectious organic waste. Alternatively, the fermentation process can be continued without replenishment of the fermentation promoter by adding new infectious organic waste to be treated in a mixture of infectious organic waste and organic waste that has almost finished fermentation. It can also be done.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Blood (whole blood) 2, 4
FIG. 6 shows the results obtained by mixing 00 cc with 2,400 kg of ordinary garbage, performing fermentation treatment, and measuring the degree of degradation of human hemoglobin over time. As shown in FIG. 6, it can be seen that about 97.5% of human hemoglobin is rapidly degraded in about 40 minutes from the start of fermentation. The fermentation temperature during this period did not reach 65 degrees Celsius, which causes thermal protein denaturation, and the decrease in human hemoglobin concentration in the fermentation product is considered to be due to fermentation degradation of microorganisms. And about 80 minutes from the start of fermentation, the internal temperature has reached 80 degrees Celsius,
After 2 hours, the temperature is over 90 degrees Celsius and about 99.degree.
0% of human hemoglobin is degraded. In addition, the internal temperature has reached 65 degrees Celsius in about 50 minutes from the start, and the internal temperature does not decrease thereafter. Therefore, when about 1 hour and 30 minutes have elapsed from the start of fermentation, various viruses and pathogenic bacteria, such as tuberculosis bacteria, pathogenic Escherichia coli and eggs, can be sterilized, and the problem of hygiene can be solved.

The fermented product thus obtained contains a large amount of minerals, particularly iron, in blood and can be effectively used as compost. In addition, since microorganisms propagate in the fermented product, the fermented product obtained by fermenting infectious organic waste can be reused as a fermentation accelerator or as a base material.

[0038]

As described above, according to the present invention, waste blood,
Infectious organic waste including waste serum, waste plasma, body fluids, gauze, cotton wool and the like to which they are attached has a total water content of 30%.
Since the fermentation treatment is performed by mixing and adjusting the mixture at a ratio of up to 60%, there is no environmental pollution such as exhaust gas due to the incineration treatment as in the conventional case. Since expensive incineration equipment is not required, there is an effect that the processing cost can be significantly reduced.

Further, according to the present invention, the fermented product obtained by fermenting infectious organic waste with microorganisms is used as compost, so that the blood which has been used but has not been used has been incinerated. It is possible to recycle without having to do so, and there is an effect that the good will of the blood donor is not wasted. Further, since the fermentation treatment product contains microorganisms, there is an effect that this can be reused as a fermentation accelerator.

In the present invention, further, in the fermentation step, the infectious organic waste is sterilized by raising the temperature to 80 degrees Celsius by the heat of fermentation of microorganisms.
By sterilizing bacteria and the like, there is an effect that it is possible to provide a method for treating infectious organic waste having no hygienic problem.
