Abstract

A process for compost production in which an organic waste, such as excreta, of high water content can be solidified or granulated through reaction with wollastonite and sulfuric acid within an extremely short period of time to thereby attain odor improvement but also fermentation, namely, composting by an effective microbe can be certainly carried out even on a reduction-to-practice level of large processing amount. Composting is accomplished by mixing wollastonite into an organic waste; subsequently mixing concentrated sulfuric acid into the mixture to thereby effect reaction leading to solidification or granulation; thereafter mixing the solid or granule with an organic waste impregnated with heated oil so as to lower its water content; adding an effective microbe to the resultant mixture as a culture medium; and carrying out fermentation.

Description

200538419 (1) IX. Description of the invention [Technical field to which the invention belongs] The present invention relates to a method and a device for manufacturing compost and compost. In more detail, it's related to the treatment of compost obtained from high-water content organic waste such as livestock manure and human waste, and organic waste with high water content to make compost. In the practical stage, the manufacturing method and device for compost compost can also be reliably made. [Prior art] It is well-known that silicon (Si) is accumulated in the cell walls of most plants, and is one of the most important elements for plants. In Okinawa, Japan, where the inventors live, the amount of sugarcane harvested is decreasing year by year. This is of course because the soil is affected by chemical fertilizers and herbicides, and the reason should be that a large amount of silicon flows out of the soil together with other trace elements, or is brought out by the crop, causing the sand in the soil to be not Φ Sufficient to make the overall soil fertility worse. In fact, in facilities such as boilers using sugarcane pomace as fuel, a large amount of silicon is attached to the combustion furnace, and even removal operations must be performed. From this, it can be easily imagined that the amount of silicon in the soil caused by crops cannot be ignored. Even if the crops are grown on soils with poor soil fertility, the stems cannot be thickened, and the fruit leaves cannot be enlarged. Naturally, they cannot be fully harvested. However, even if the amount of silicon in the soil is insufficient, only the inorganic silicon such as diatomite is simply mixed into the soil in a powder state, and the crop 200538419 (2) cannot be fully absorbed. For crops to absorb silicon, ionized silicon must be present in the soil. In order to achieve this, the present inventors have repeatedly studied for many years. Next, it was learned from experiments that mixing silicon into organic matter, and further reacting it with concentrated sulfuric acid, promoted the ionization of silicon, composted it, and fertilized it, which had the effect of restoring soil fertility. However, in Okinawa Prefecture, there are many pigs reared, and the disposal of pig manure # has also become a major social problem. Swine manure is an organic waste. The inventors of the present invention used it as a raw material for composting, and noticed this swine manure. In addition, many methods have been proposed and implemented to treat organic waste such as feces, but methods of obtaining organic fertilizers using silica-containing wollastonite have been proposed (see Patent Document 1) 〇 Patent Document 1: Japanese Patent Application Laid-Open No. 1 0- 1 523 8 5 describes a method for producing an organic fertilizer described in Patent Document 1 by using organic waste of livestock manure and urine with high moisture content and natural wollastonite. Reacts with concentrated sulfuric acid, solidifies or granulates in a very short time to improve the odor of organic waste, and because of the heat of reaction, most of the miscellaneous bacteria are extinct. (Composting) can also be made easier. [Summary of the Invention] [Problems to be Solved by the Invention] The present inventors have confirmed whether it is possible to make compost by using a method for producing organic fertilizer described in Patent Document 1 described in 200538419 (3) described above. But then I learned that in the practical stage of large-scale processing of feces and urine, even if effective microorganisms are added to the mixture that becomes the culture medium, it will not ferment after four months, making it impossible to make compost. Therefore, the present inventors have tried various experiments for fermenting the above-mentioned solidified or granulated mixture in a practical stage. Also, in this experiment, when experimentally adding vegetable seed oil to the mixture, fermentation started the next day after adding # effective microorganisms. Although the reason is not clear, it should be the oil or some other ingredient contained in the vegetable oil, which effectively participates in or contributes to the fermentation of effective microorganisms. The present inventors focused on this result, and repeated the research on the treatment scale of organic waste with high water content, which is considered to be relatively high compared with livestock manure or human feces. And completed the present invention. • (Object of the present invention) The object of the present invention is to provide compost obtained from the treatment of organic waste of livestock and human waste, high-water-content organic waste, and high-water-content organic waste. Even in a practical stage with a large amount of processing capacity, the method and device for manufacturing compost can be reliably fermented to produce compost. [Means to Solve the Problem] The means of the present invention conceived to solve the above-mentioned problems are as follows-200538419 (4) The first invention is a compost, which is to discard organic materials with high water content The compost obtained by fermentation is characterized by solidified or granulated matter obtained by mixing concentrated sulfuric acid with a mixture of wollastonite and organic waste with a high water content, and adding organic waste with heating oil. The organic waste with a reduced moisture content is immersed and mixed, and the mixture is used as a culture medium to add effective microorganisms for fermentation. Φ The second invention is a method for producing compost, which is a method for producing compost from organic waste with a high water content. It is characterized in that wollastonite is mixed with organic waste with a high water content. In an object solidified or granulated by mixing concentrated sulfuric acid to cause a reaction, the organic waste is mixed with heating oil to immerse the organic waste to reduce the water content, and the mixture is used as a medium to add effective microorganisms. Fermentation. The third invention is a method for producing compost, which is a method for producing compost from organic waste with high moisture content. It is characterized in that 100% by weight of organic waste with high moisture content is mixed with wollastonite. 10 to 25 parts by weight, and then mixed with 5 to 15 parts by weight of concentrated sulfuric acid to cause reaction or solidification or granulation, to mix 15 to 25 parts by weight 'organic waste with heating oil The organic waste with an oil immersion treatment to reduce the water content is used as a culture medium to add effective microorganisms for fermentation. The fourth invention is a method for manufacturing a compost according to the second and third inventions, which is characterized by adding zinc (Zn), manganese (Mn), molybdenum (Mo), magnesium (Mg), copper (Cu), One 200538419 (5) or more selected from iron (Fe). The fifth invention is a compost manufacturing device, which includes an organic waste supply device, a wollastonite supply device, and an organic waste mixing device that mixes and supplies organic waste and which is to be disposed of in organic waste. In the material mixing device, the mixed mixture is mixed with the supplied concentrated sulfuric acid, and the reaction device is caused to react by mixing and stirring, and the heating waste is used to oil-immerse the organic waste, thereby reducing the organic waste content. A heating oil immersion treatment material supply device, and a fermentation device that adds effective microorganisms to a mixture of the material obtained from the reaction device and the material supply from the heating oil immersion treatment material supply device to ferment the mixture. The sixth invention relates to the compost manufacturing device according to the fifth invention, characterized in that the reaction device is provided with a screw conveyor that conveys the mixed and stirred mixture and the concentrated sulfuric acid while stirring, and mixes the concentrated The sulfuric acid part is provided on the conveying base side of the screw conveyor or the conveying path of the mixture to the conveying base side. Φ The seventh invention relates to the compost manufacturing device according to the fifth and sixth inventions, which is characterized in that the wollastonite supply device has a communication device with at least a plurality of organic waste stirring devices, and selectively Wollastonite is supplied to each organic waste stirring device, and the odor in the organic waste stirring device will not be leaked from the supply part to the external distribution device. The organic wastes with high water content to be treated are, for example, sewage sludge, excess sludge, shochu waste liquid, fecal urine (pig feces urine, cattle feces urine, human feces urine, human feces urine), sugarcane pupae, and the like. Moreover, organic waste is not limited to this. -8-200538419 (6) Wollastonite (calcium silicate: CaSi03) used can be natural or synthetic. For 100 weight points of organic waste, the ideal mixing ratio of wollastonite is 10 to 25 weight points. A more ideal choice is 15 to 18 weight points. Also, similarly, the ideal mixing ratio of concentrated sulfuric acid is 5 to 15 parts by weight. A more ideal choice is 8 to 10 weight points. If the wollastonite is less than 10 parts by weight or the concentrated sulfuric acid is less than 5 parts by weight, # solidification or granulation will not proceed sufficiently, and the reaction temperature will also be lowered and there will be a tendency to leave germs. In addition, if wollastonite exceeds 25% by weight or concentrated sulfuric acid exceeds 15% by weight, there is almost no difference in curing or granulation and reaction temperature. Therefore, this only wastes excess portions of wollastonite and concentrated sulfuric acid. Moreover, if wollastonite exceeds 25 weight%, it will become too hard, and it will become difficult to handle it. In addition, the ideal ratio of reducing the water content of the organic waste mixed with the above mixture by oil immersion treatment with heating oil is 15 to 25 weight percent. If the proportion is less than 15 weight percent, there is a tendency that fermentation will not proceed sufficiently even if effective microorganisms are added, and even if it exceeds 25 weight percent, there will be almost no difference in fermentation speed or efficiency, so excess waste will occur. Weight tendency. Examples of a series of effective microorganisms (fermentative bacteria) for fermenting the mixture include aerobic and anaerobic microorganisms, such as Lactobacillus (double fork lactobacillus, etc.), Saccharomyces (bacillus, etc.), and photosynthetic bacteria ( Chlorella, etc.), fermented filamentous bacteria, Gram-positive actinomycetes, etc., but it is not limited to this. 200538419 (7) Oil-immersion treatment of organic waste with heating oil to reduce the moisture content, as the water contained in the organic waste evaporates, it will be reduced in volume. Generally, centrifugal force or compression is used. Force to drain the oil to reduce the oil content and use it again. In order to prevent the compost from continuous cropping and other adverse effects on the soil ', the content of oil with reduced water content should be less than 5%. The content of oil is not limited to this. For organic wastes that have been oil-immersed with heating oil, for example, sewage sludge, excess sludge, kitchen waste (raw waste), tofu shells, food residues, shochu liquor, livestock or human waste , Sugarcane pupae and so on. Organic waste is not limited to this. Heating oil immersion treatment uses ordinary oil. As for the used oil, considering the problem that the oil is used in compost, from the viewpoint of environmental preservation, the ideal choice is vegetable oil (rapeseed oil, etc.) or animal oil ( Lard, etc.). The heating oil immersion treatment material supply device may be a device that only provides heating oil for oil immersion treatment of organic waste such as kitchen waste or excess sludge to reduce water content, or heating oil for oil immersion treatment of organic materials. Waste and devices with storage tanks. The device for oil immersion treatment with heating oil may be a device for processing organic waste under normal pressure, or a device for processing at a higher pressure than normal pressure and at a higher temperature than normal pressure. . It may also be an apparatus that performs processing at a lower pressure than normal pressure and at a lower temperature than that at normal pressure. -10- 200538419 (8) (Action) The present invention works as described below. Heat-oil is used for oil immersion treatment of organic wastes with high moisture content such as faeces and urine, and organic wastes such as kitchen waste to reduce the moisture content, and are appropriately stored in storage units such as tanks. In addition, appropriate amounts of wollastonite and concentrated sulfuric acid were also stored in storage units such as tanks. Then, for example, one or more elements selected from zinc (Zn), manganese (Mn), molybdenum (Mo), magnesium (Mg), copper (Cu), and iron (Fe) are added in advance to Wollastonite. The organic waste with high moisture content is put into or transported to the organic waste mixing device. When an appropriate amount is stored in the organic waste stirring device, it is mixed in the required ratio and mixed and stirred. Concentrated sulfuric acid is mixed into the mixture mixed and stirred with an organic waste stirring device, and stirred in a reaction device to cause a reaction. By this reaction (reaction of wollastonite and concentrated sulfuric acid), the mixture will be solidified or granulated in a short time, and the odor that is unique to organic waste such as feces and urine will be improved. In addition, because the reaction heat is generated, although the temperature of the mixture may vary with different conditions, for example, it becomes 7 5 to 8 5 t, by which, the miscellaneous bacteria containing harmful bacteria such as pathogenic bacteria in the mixture are almost extinct. . Next, when the solidified or granulated mixture made from the organic waste is cooled to an appropriate temperature (for example, the temperature at which effective microorganisms can multiply), it is supplied by a heating oil immersion treatment material supply machine to heat the oil to oil The organic waste is dipped to reduce its moisture content, and then these are mixed, and effective microorganisms are added and the time required for fermentation by a fermentation device is composted. Also, it can be mixed with solidified or granulated mixture -11-200538419

The product and the heated oil immersed product are cooled and then added with effective microorganisms. Regarding a mixture that becomes a medium for adding effective microorganisms, since a solidified or granulated mixture produced from organic waste was once heated to a high temperature, almost no bacteria including harmful bacteria such as pathogenic bacteria were present. Therefore, the added effective microorganisms can be fully activated, and a good quality compost can be efficiently produced. In addition, the conveying of the mixed material to the fermentation apparatus is carried out by using various conveyors such as screw conveyors or belt conveyors, and using an overhead crane to carry containers such as containers for transportation. As long as a screw conveyor is used to convey the stirred mixture and the mixed sulfuric acid while stirring, the portion with the concentrated sulfuric acid is placed on the conveying base side of the screw conveyor, or it is passed to the conveying base side The compost manufacturing device of the reaction device on the mixture conveying path requires almost no injection pressure and the like for mixing concentrated sulfuric acid, so the device can be simplified. # That is, the conveyance path of the conveyer base side or the conveyance base side of the screw conveyor is a negative pressure by continuously moving the mixture to the conveyance rear side (discharge side) by spiral rotation. Part. Therefore, concentrated sulfuric acid can be effectively mixed as if inhaled. In addition, since the concentrated sulfuric acid is mixed in the screw conveyor (the front part of the conveyance), the mixture is sufficiently stirred until the mixture is sent to the rear part of the conveyance (the exit side). Wollastonite and concentrated sulfuric acid are relatively speaking Although the reaction is shown earlier, almost uniform solidification and granulation can be achieved as a whole. With this, effective compost manufacturing can be achieved. -12- 200538419 (10) As long as at least a plurality of organic waste agitating devices are used, and wollastonite can be selectively supplied to each organic waste agitating device, and organic materials from the supply part are not allowed The compost manufacturing device of the waste mixing device leaking the odor of the waste distribution device to the outside distribution device can transport the organic waste and wollastonite to the other The waste agitator prepares the next operation. With this, effective compost manufacturing can be achieved. φ In addition, the odor of organic waste does not leak to the outside, so it can prevent the odor from causing deterioration of the working environment or causing trouble to the surrounding area. [Effects of the Invention] The present invention has the above-mentioned configuration and has the following effects. (a) As long as the present invention is used, according to the required ratio, the organic wastes with heating oil are oil-immersed to reduce the water content, and mixed with silica ash # stone and concentrated sulfuric acid to cure or granulate, A mixture of high-water-content organic wastes such as animal manure and human feces, and the addition of effective microorganisms, even in a practical stage with a large amount of treatment, can be fermented in a good state to obtain compost. (b) As long as the screw conveyor is used to transport the stirred mixture and the material mixed with concentrated sulfuric acid while stirring, the portion with mixed concentrated sulfuric acid is set on the side of the conveying base of the screw conveyor, or it is passed to The compost manufacturing device of the reaction device of the mixture conveying path on the conveying base side 'until the mixture is sent to the rear conveying part (exit side), it has been charged with 13-200538419 (11). Although the reaction will be shown earlier, almost uniform solidification and granulation can be achieved as a whole. In this way, effective compost manufacturing can be achieved. Further, since the pressure such as the injection pressure for mixing the concentrated sulfuric acid is almost unnecessary, the apparatus can be simplified. (C) As long as at least a plurality of organic waste agitating devices are used, and a wollastonite can be selectively supplied to each organic waste agitating device, and the organic waste agitating device can be prevented from being transmitted from the supply part ## The compost manufacturing device that leaks odor gas to the external distribution device can transfer organic waste and wollastonite to the other organic waste mixing device when one organic waste mixing device performs stirring treatment, etc. Device to prepare for the next job. With this, effective compost manufacturing can be achieved. In addition, the odor of organic waste such as wet pig dung or human dung does not leak to the outside. Therefore, it can prevent the foul odor from causing deterioration of the working environment or causing trouble to the surrounding area. # [Embodiment] [Best Embodiment of the Invention] The present invention will be described in more detail based on the embodiment shown in the drawings.

The sulfuric acid introduction pipe 23 passes through the spherical joint 24, and is opposite to the rotary valve 72 7 b 1, 1 a provided in the long valve part of the stirring tank, and the control of the valve 72 6 (b) is not caused! 20 〇 02 02 Tied with a plate 94. Introduction The introduction pipe has the above-mentioned -21-200538419 (19) The supply pipe i ο 9 on the discharge side of the machine waste agitating device 1, 1 a is connected. The reaction device 2 supplies concentrated sulfuric acid from a concentrated sulfuric acid supply device 8 (shown in FIG. 2). The concentrated sulfuric acid supply device 8 has a concentrated sulfuric acid tank 80. A transfer pipe 81 is provided between the concentrated sulfuric acid tank 80 and the sulfuric acid introduction pipe 23 of the reaction device 2. A pump 82 is provided in the path of the conveying pipe 8 丨. The delivery pipe 81 is connected to the injection pipe 83 whose front end side is branched into two directions. The two branch pipes 830 of the injection pipe 83 are introduced through the side walls 23 0 at two points on the diameter line of the sulfuric acid introduction pipe 23 φ. The inner surface of the side wall 23 0 is fixedly installed and covers the opening part of the front end of the branch pipe 8 3 0 from a distance, and the baffle 2 3 1 (refer to the conveying direction side) below the opening (see the first section). Figure 9 (b)). With this structure, the pressure of the mixture discharged from any one of the mixing tanks 1 and 1 of the organic waste stirring device 1, which is conveyed through the sulfuric acid introduction pipe 23, does not easily act on the front end of the branch pipe 8 30. Therefore, it is possible to smoothly perform the injection of concentrated sulfuric acid Φ without applying a particularly strong pressure. This also simplifies the device and eliminates the need for a compressor or the like that applies pressure to the injection of concentrated sulfuric acid, thereby reducing manufacturing costs. The connecting pipe 2 6 at the front end of the reaction device 2 is connected to the base side of the screw conveyor 27. The front end side of the screw conveyor 27 is extended obliquely upward, and is configured to be self-locating on the transportation container 5 (illustrated in FIG. 2 and FIG. 3) disposed behind the organic waste disturbance companion device 1, 1 a It was then contained in it. The bottom of the 'conveying container 5 is provided with a switchable dropper (illustration and symbol omitted). After the required amount of the mixture has been accumulated, the mixture -22- 200538419 (20) will be transported to the fermentation tank 40 described below together with the container, and will be introduced through the inlet. Before the mixture is placed in the fermentation tank 40, a predetermined maturity period may be placed in the transport container 5 in advance. (Heating oil immersion treatment material supply device 3) The heating oil immersion treatment material supply device 3 is disposed behind the organic waste stirring device 1 and 1a (on the upper side in FIG. 2). • In this embodiment, an oil temperature decompression drying device (TEMPLAR-M21: PROREX Co., Ltd.) is used as the heating oil immersion treatment material supply device 3. In addition, as for the heating oil immersion treatment material supply device 3, any other device may be used as long as it can perform oil immersion treatment with various organic wastes of the heating oil group and reduce the water content. Regarding the structure and function of the heating oil-immersed processed material supply device 3, only a brief description will be given here, and a detailed description will be omitted. The heating oil immersion processing material supply device 3 is composed of (1) raw material line (line ♦), (2) drying line (heating oil immersion processing line), (3) oil pressing refining line, (4) product line, (5) vacuum Line, (6) deodorization line, (7) vapor line. Further, a conveying device such as a screw conveyor for conveying the heated oil-immersed processed product in a subsequent process may be provided. The heating oil immersion treatment material supply device 3 series (1) carries raw materials such as kitchen waste through a raw material line, and heats and stirs them to make them fluid, and then stores them. Next, (2) The oil heated by the drying line and (7) the vapor line as a heating source is used as a heating medium, and the moisture of the raw materials is removed under a reduced pressure (under vacuum) to perform a heating oil immersion treatment. The evaporated water is attracted by the vacuum line (5) -23- 200538419 (21) 'and is condensed to be drained. In addition, the odor is subjected to a deodorizing treatment by the (6) deodorizing line. In addition, the solid matter and oil are separated by the (3) oil-refining line to obtain a heated oil-immersed product (semi-product) whose oil content is adjusted to 5% or less. Finally, the (4) product line is used to process the heated oil immersion treatment into a uniform powder, which is stored after cooling and supplied to the post-processing. φ (fermentation device 4) Refer to FIG. As shown in FIG. 1, the fermentation device 4 is installed at a position ′ away from the organic waste stirring device 1 and 1 a. The fermentation device 4 is provided with a fermentation tank 40 'and a mobile stirring device 41 which is provided with a fermentation tank 40 which is moved back and forth along the side wall of the fermentation tank 40 to stir the internal mixture' and sent to the discharge side. In the fermentation tank 40, the processed material and the odor sent from the tank 60 are simultaneously fermented. In addition, the fermentation device 4 φ having the fermentation tank 40 and the mobile stirring device 41 is a well-known general structure. Therefore, detailed descriptions are omitted (action). Refer to FIG. 1 to FIG. 9 as processing targets. For example, the case of processing pig manure or human manure with a high water content is taken as an example to explain the role of the compost manufacturing plant p. An appropriate amount of feces and urine is stored in the tank 60 in advance. Also, “storing an appropriate amount of wollastonite in the wollastonite tank 70” is to store an appropriate amount of concentrated sulfuric acid in the concentrated sulfuric acid -24- 200538419 (22) tank 80 in advance. Wollastonite is added with an appropriate amount (usually also a trace amount) of zinc (Z η), manganese (Μ η), molybdenum (Μ 〇), magnesium (M g), copper (C υ), and iron (Fe) in advance. One or more selected elements. This is to replenish sufficient minerals in the compost. In addition, it is generally desirable to add all of the above-mentioned types, but it is also possible to add appropriately selected elements in accordance with the state of the fertilized soil and the like. The blending ratio may be adjusted as appropriate, and is not particularly limited. The feces and urine are selectively transferred to each of the stirring tanks 10 of the organic waste stirring device 1 and 1 a. When an appropriate amount is accumulated in each of the stirring tanks 10, the wollastonite is supplied to one of the stirring tanks 10 by the distribution device 72 of the wollastonite supplying device 7, or one of the stirring tanks 10 is made. Wollastonite is for faeces! 00 parts by weight are blended at a ratio of 15 parts by weight, and mixed with a blender 1 2. The valve 107 was opened, and the mixture mixed and stirred in the organic waste stirring device 1 or 1 a was sent to the reaction device 2. The concentrated sulfuric acid supplied through the concentrated sulfuric acid supply device 8 is injected into the sulfuric acid introduction tube 23 of the reaction device 2 through the injection pipe 83 from two opposite directions. Concentrated sulfuric acid is formulated at a ratio of 8 parts by weight based on 100 parts by weight of feces and urine. The mixture mixed with concentrated sulfuric acid is then sent to the screw conveyor 20, and is conveyed to the discharge side while being stirred in a spiral 202 in a circular tube 201. After mixing the mixture with concentrated sulfuric acid, the wollastonite mixed in the mixture causes a chemical reaction with the concentrated sulfuric acid. -25- 200538419 (23) With this reaction, the mixture can be solidified or granulated in a very short time, and the odor that is unique to feces and urine can be improved overnight. In addition, the heat of reaction is generated, and the temperature of the mixture becomes 75 to 85 ° C. The miscellaneous bacteria including harmful bacteria such as pathogenic bacteria existing in the mixture are almost extinct. The solidified or granulated mixture is conveyed to the conveyance container 5 by the screw conveyor 27, so that an appropriate amount is accommodated. The transport container 5 containing the mixture is contained in a desired ratio. The heating oil is immersed with heating oil to reduce the water content of the heated oil immersion treatment product, and then it can be moved along the ceiling track. A moving crane (not shown) lifts and transports it to the fermentation tank 40. Then, you can open the lower drop opening to drop into the tank. Next, the heated oil-immersed processed material supplied by the heated oil-immersed processed material supply device 3 is stored in the transport container 5 described above. The mixing ratio of the mixture of pig manure or human feces treated in the transport container 5 and the heated oil-soaked treatment product is 100 weight points of the treated pig manure mixture, and #the heating oil-soaked treatment product 50 weight Minutes, and then mixed to reduce compost 50 weight. This ratio is appropriately adjusted within a range in which fermentation can be effectively performed. The transport container 5 is transported to the fermentation tank 40 of the fermentation apparatus 4 using a crane (not shown). The heating oil immersion treatment system is not necessarily required, and the processed feces and urine mixture is mixed in the transport container 5. For example, the mixture may be mixed while being transported to the fermentation tank 40 by other means such as a screw conveyor, or may be Mix in the fermentation tank 40. The mixture that becomes the culture medium is naturally cooled in the fermentation tank 40. When -26- 200538419 (24) is cooled to a temperature at which effective microorganisms can reproduce, an appropriate amount of effective microorganism is added. Then, the stirring device 41 is moved to mix and stir the time required for fermentation and composting. In addition, since there is almost no miscellaneous bacteria containing harmful bacteria such as the above-mentioned pathogenic bacteria in the mixture, the effective microorganisms added will be sufficiently activated. In addition, since the mixture treated with pig dung or human dung is fermented by adding a heated oil-immersed treatment at the above ratio, the fermentation can be performed in a good φ state, and good compost can be obtained. Although this reason has not yet been determined, it should be the nitrogen rich in the heated oil immersion treatment product or the amino acid produced by the concentrated sulfuric acid decomposition of the protein rich in the heating oil immersion treatment product, which is necessary for the supply of effective microorganisms. Energy 〇 In the practical stage with a large amount of treatment, we tried to mix the treated faeces and urine as a culture medium without adding heated oil-immersed treatment, and fermented with effective microorganisms. However, during the test period of 4 months内 ， 都曾 # fermented. On the other hand, the method of mixing heated oil-immersed treatment material as a culture medium in a mixture of processed feces and urine will start fermentation the next day when effective microorganisms are added. Next, "Experimental Example 2" in which a heated oil-immersed treatment is mixed with pig manure and urine treatment and fermented to produce compost will be described below. Pig manure treatment was used in any of the experimental examples. A mixture of 25 wt.% Wollastonite and 15 wt.% Concentrated sulfuric acid was mixed with 100 wt.% Of swine manure to cause a reaction and granulation. In Experimental Example 1 shown in Table 1, the remaining sludge was used as a raw material for the heated oil immersion -27- 200538419 (25). In Experimental Example 2 shown in Table 2, kitchen waste was used as a raw material for heating the oil-immersed treated product.
