In the conventional method described above, as a step before mixing the moisture regulator with the main raw material, it is necessary to separate the main raw material with high moisture content into solid-liquid, and to crush the rice husk, bark, etc. that will serve as the moisture regulator. The production and equipment costs of compost are extremely high due to the use of fuel, effective enzymes, and expensive fermenter equipment. In addition, rice husks that are not crushed are
Although it has a fairly low moisture content of about 10%, it has poor moisture absorption. Therefore, as mentioned above, the rice husks are pulverized to improve moisture absorption, but since water is added during pulverization, the moisture content of the pulverized rice husks is reduced.
Since the ratio is about 40%, a large amount of crushed rice husks must be added to the human waste, which further increases production costs.

In the method of the present invention, in the first step, in addition to the uncrushed rice husks used as a moisture regulator, a part of the product compost with low moisture obtained in the third step is returned to produce human waste that does not undergo solid-liquid separation. Because of this, even if raw human waste with a high water content is used as the main raw material, the moisture content can be reduced to 60 to 65% without solid-liquid separation or with less addition of new moisture regulators such as rice husks. % can be used as compost raw material.

なつている。 The stirring/mixing section 4 has a rotating shaft 41 . A plurality of blade support rods 42 are spirally erected in the radial direction of the rotating shaft 41 so as to face at least the axial direction of the rotating shaft 41 . The blade support rods 42 erected along this spiral are connected to adjacent blade support rods 42 by ribbon-shaped blades 43 at their tips except for a part. That is, the structure is such that a part of the spirally continuous ribbon-like blade 43 is cut out between some adjacent blade support rods 42.

込みやすくなつている。 Therefore, when the compost raw material obtained in the first step is put into the mixing and stirring device 1 from the hopper 21,
The screw conveyor 22 transports the materials to the crushing section 3 while being stirred and mixed. In the crushing section 3, the compost raw material is crushed and further sent to the stirring and mixing section 4. In the stirring and mixing section 4, the compost raw material is cut by the blade part 44 of the ribbon-shaped blade 43, and is also struck by the side wall surface 45 of the cutout part of the ribbon-shaped blade 43. , the uncrushed rice husks in the compost raw material are brought into a water-absorbing state. That is, the ribbon-like blade 43 functions like a cutter and a hammer. Moreover, the compost raw materials are transferred while being retained and mixed and stirred, and during this time, the compost raw materials are integrated by the inhalation of oxygen and the friction of the generated compost raw materials. In addition, rice husks are dispersed and mixed in the compost raw material, and compared to the case where only product compost (returned compost) is used as a moisture regulator, oxygen, which is one of the fermentation conditions, is added to the compost raw material during mixing and stirring. It's getting easier to take in.

された製品堆肥（醗酵堆肥）が製造される。 In this way, the compost raw materials, which are the various conditions for fermentation, are unified and have frictional heat, moisture, oxygen, and nutrients, and are then taken out by a screw conveyor with a stirring and mixing function and transferred to a tire shovel. It is deposited in an indoor fermentation storage area. Because the accumulated compost materials already have the conditions for fermentation, a large number of microorganisms multiply in an extremely short period of time, and their activity raises the temperature to 70-75℃, producing sugars, proteins, fats, The decomposition of cellulose and lignin is promoted in this order, and the temperature decreases in about 7 days. Further, as the temperature increases, the moisture in the deposit evaporates, and the amount of moisture in the deposit decreases. Furthermore, by turning back the deposit once the temperature has fallen,
The temperature rises again to accelerate decomposition and drying. By repeating this process 3 to 4 times, fermentation and drying are accelerated, resulting in excellent properties.
In addition, as shown in FIG. 1, product compost (fermented compost) dried to a desired moisture content is produced.

効果がある。 As described above, according to the method for producing rapidly fermented compost in the human waste treatment process according to the present invention, uncrushed rice husks can be used as a moisture regulator without pretreatment, and part of the fermented product compost can be used as a moisture regulator. Since the rice husks are sent back for use, there is no need to use much rice husk as a moisture regulator. In addition, by using the above-mentioned moisture regulator, even if the main raw material has a high moisture content, by increasing or decreasing the amount of returned product compost without solid-liquid separation,
It can be freely adjusted to an appropriate hydration state. Fuel and enzymes for fermentation are achieved through the use of product compost and sufficient agitation and mixing during the transfer process. Furthermore, fermentation is carried out in a restrained state in an indoor pile for fermentation without using a fermentation tank, and the moisture content reaches a predetermined value, making it possible to produce high-quality product compost. Therefore, it is possible to reduce expenses and equipment costs significantly, and to produce and provide fermented compost with good properties at a low cost, with uniform moisture content and properties, and rich in the three elements of fertilizer.
