Field of the Invention The present invention relates to a high-speed processing method for organic waste containing a large amount of water, such as organic sludge (food industry waste sludge, human waste sludge, sewage sludge), feces storage, kitchen waste (garbage), and the like.

％に低下させて発酵させコンポスト化を図っていた。BACKGROUND OF THE INVENTION Sludge, which is an organic waste from various industries, is rich in high protein and carbohydrates, even though it has a water content of more than 80%, such as organic sludge of food. If fertilizer is made by fermentation, waste can be effectively used. In view of the high water content, which is a factor inhibiting fermentation, in the fermentation treatment of organic waste, a water regulating material such as rice straw, rice husk, sawdust has been added, and the total water content has been reduced to 55% to 60%.

少なくされることになる。[0003] However, the fermentation treatment with the addition of the water conditioning material is basically an anaerobic fermentation, and the fermentation temperature is low. Originally, lignin contained in wood, peach and so on, and the woody part of peach containing silicic acid are very hard to decompose and are anaerobic fermentation and low-temperature fermentation. In order to decompose these additives present in large amounts, the primary fermentation for about 12 days followed by about 2 months for 2 days
Next fermentation is required. Further, even after the secondary fermentation is completed, the rice husks and sawdust do not completely decompose, and the solid content of sludge and the remaining moisture regulator coexist in the fertilizer produced.
Eighty percent of the organic sludge is water, which evaporates during the fermentation process, and only up to 20% solids of the organic sludge in the fertilizer. If about 30% of the water conditioning material remains, the content of components such as high nitrogen content and phosphoric acid of the organic sludge will be extremely reduced.

Moreover, the need for secondary fermentation for two months or more is the greatest weakness of the current organic sludge treatment method. This is the cause of the current situation where only about 1% or less of the generated sludge is treated.

By securing, the air contact area of sludge is expanded, and aerobic fermentation is possible. And the specific means of fermentation is
The processing target stored in the pool-shaped open fermentation tank is subjected to stirring and switching by the stirring blade while supplying air. Depending on the difference in the processing target, the processing target is 2 to 2 times. It took three weeks.

It is housed in a closed fermentation vessel that can supply air from the bottom and has a predetermined heat insulation structure, performs aerobic fermentation while supplying a large amount of forced air for a predetermined period, and press-molds the object to be treated. It is characterized by having a possible viscosity.

形可能となる。That is, when air is supplied in an amount capable of aerobic fermentation in a fermenter in which only natural exhaustion is performed in accordance with the supply air for aerobic fermentation, the fermentation target (a mixture of organic waste and waste paper) The waste paper in the parentheses) evaporates water and absorbs water from organic waste, so that water is evaporated and aerobic fermentation of organic waste is performed at the same time. The heat radiation is limited because of the inside of the heat insulation container, and the fermentation heat is effectively used for water evaporation. Therefore, the fermentation can be continued without turning over, and the fermentation can be terminated quickly. Since the mixed waste cellulose is not cut, it becomes a paper clay and can be pressure-formed.

As shown in FIG. 1, the fermentation apparatus used in the fermentation method shown in the embodiment has an appropriate heat insulation structure (in the sense that it is not made of metal plate or thin resin. A fermenter 1 having a structure that is hardly released into the outside air is sufficient.
The inside of the fermenter 1 is provided with an inner bottom 3 serving as a double bottom with a large number of ventilation holes, and a blower 4 is connected to a space below the inner bottom 3 to form a lid. 2 is provided with an exhaust port and an exhaust blower 5 connected to the exhaust port, and further, a stirring mechanism 6 is provided on the inner bottom surface 3. In addition, the inner lid 7 is covered with the fermentation processing target (organic waste and waste paper mixture processing target) A stored on the inner bottom surface 3.

When forced exhaustion of 50 L was performed, it was recognized that the target temperature reached 70 ° C. three days later, the high temperature continued for two days, and the fermentation was completed ten days later (see FIG. 2).

対象物を保護する効果を有する。As a result of various trials and errors, if the temperature of the air is raised to 70 ° C. within 48 hours by adjusting the ventilation and exhaust air, and maintained at 70 ° C. for 2 days or more, and further maintained at 60 ° C. or more for 4 days, sufficient fermentation is performed. It was confirmed that compost having a water content of about 55% was obtained. Therefore, compared with the conventional waste paper mixed fermentation processing means, the processing can be performed in a shorter time. In addition, the stirring mechanism 6 is used to prevent the cellulose of the used paper from being cut apart in order to prevent the ventilation of the processing object A from blocking the ventilation part, fixing the ventilation part, or unevenly distributing the ventilation part.
Slow stirring is performed as needed. In addition, the inner lid 7 protects the processing target from the volume reduction of the processing target due to moisture evaporation and protects the processing target from dew condensation in the upper space inside the fermenter 1 caused by the reduction of the processing target. It has the effect of doing.

は広がるものである。The above-mentioned fermented product (compost) has a water content of about 55%, cellulose is not finely cut, exists in a long fiber state as it is, and maintains a tangled state like paper. Therefore, a 2 × 2 × 7 cm test piece, which was compacted as it was and dried to a moisture content of 20%, was subjected to RdD
When a tensile test was carried out using an RTC-1225AS type tester manufactured by the company, the tensile strength was 117 kg / cm 2, and it had sufficient shape retention without requiring a special binder. That is, by adopting the above-mentioned organic waste fermentation treatment method, it is possible to obtain granules having an arbitrary size and compost having a desired shape, and the range of use thereof can be expanded.
