As a result, the air blower 23 supplies air containing oxygen ventilated through the ventilation means while directly applying the air in the fermentation house 10 toward the garbage put in the fermenter 12. ing. As a result, the garbage is aerobically fermented and rapidly decomposed. Moreover, since the air for aeration is taken in from the air in a fermentation house, the influence which takes in external air directly and deteriorates fermentation conditions decreases, and can maintain the active state of the stable fermentation microbe.
[0020]
As shown in FIGS. 3 to 6, a stirring device 38 is installed on the upper ends of both long side walls 30 of the fermenter 12 so as to ride on the rail 32 and move in the longitudinal direction of the rail of FIG. 4. ing.

[0021]
Further, as shown in FIGS. 1, 3, and 4, two suction pipes 54 are suspended by a suspension support 56 supported on the ceiling side in the interior of the fermentation house 10 along the longitudinal direction. In addition, air suction holes 58 are provided at a plurality of locations of these suction pipes 54 with a required gap therebetween. And the discharge pipe 60 which consists of a bellows pipe etc. is penetrated and provided in the wall hole drilled in four places of the long side wall 14a of the fermentation building 10, The one end of this discharge pipe 60 is connected to the suction pipe 54 in communication. . The other end side of these discharge pipes 60 is extended to the outside air side, and a suction fan 62 is connected thereto. In the embodiment, the suction means 24 includes these suction pipes 54, a discharge pipe 60, and a suction fan 62.
[0022]
Further, the suction fan 62 is connected to a deodorizing device 26 as a deodorizing means, and air containing odor in the fermentation house 10 is sent into the deodorizing tank 66 to perform a required deodorizing process, thereby complying with legal regulations. Only the air deodorized below the value is discharged to the outside.
[0023]
FIG. 7 shows a deodorizing device 26. In the figure, the deodorizing device 26 is provided with a deodorizing tank 66 in which stainless steel is formed in a hollow cylindrical shape and the inside is closed in a sealed manner with the outside air. The metal nets 68 are arranged in multiple stages at intervals so as to be divided into layers, and a microorganism deodorizing material such as peat moss is placed and filled on each metal net 68, and the upper surface of each peat moss layer 69 is used for intermittent watering. The sprinkler 70 is arranged. An exhaust pipe 72 is provided on the upper end wall inside the deodorization tank 66 so as to protrude upward, and the deodorized air is discharged to the outside from the discharge port at the upper end. For example, deodorizing treatment of malodorous components such as ammonia, methyl mercaptan, methyl sulfide, and hydrogen sulfide while air containing odor sucked from the inside of the fermentation house 10 of FIG. 7 and discharged from the discharge pipe 60 passes through each peat moss layer 69. However, when it rises to the upper layer side and is discharged from the exhaust port of the exhaust pipe 72, for example, only air that is innocuous gas such as ammonia, water vapor, and carbon dioxide and that satisfies the standard value of legal regulations is discharged. It has become. In the figure, 71 is an exhaust liquefied water reservoir, and 74 is a drain pipe. As shown in FIG. 1 and FIG. 8, in the embodiment, the deodorizing device 26 is provided separately for each of the long side walls, one for each of the four fermentation houses 10 and two for each. Ventilation inside the fermentation house can be adequately performed. You may set arbitrarily the attachment position and number with respect to each fermentation building of the deodorizing apparatus 26. FIG.
[0024]
Here, the amount of exhausted air by the suction fan 62 is set so as to be a sufficient amount of exhausted air so that the air in the fermentation house 10 can be set to a negative pressure, and the inside of the fermentation house 10 is always a negative pressure with respect to the outside air. Is set. Thus, the air in the fermentation house is supplied and refluxed to the garbage in the fermenter 12 as air for aerobic fermentation by the air blower 23 and the air supply pipe 20, while outside air is supplied from the vent hole 22 of the fermentation house 10. Aerobic bacteria that are constantly taken in and ventilated in a state where fresh outside air is always taken in the fermentation building 10 to suppress high-temperature and high-humidity due to high steam components in the fermentation building 10 due to aerobic fermentation of garbage.

[0025]
Further, in this embodiment, as shown in FIG. 8, three sewage tanks 80 are respectively installed in the vicinity of the foreign matter removal site in the vicinity of each fermentation building 10. The foreign material removal place 82 is a temporary storage place for garbage that spreads and temporarily stores garbage collected from homes and offices and removes foreign substances other than glass, plastic, metal appliances and other garbage. After temporary storage, liquid oozes out of the garbage and is discharged outside as sewage. In the embodiment, the guide channel 86 is communicated with the foreign matter removal field 82, so that the sewage automatically flows into the sewage tank 80. Further, in the sewage tank 80 and the fermentation house 10, a sewage pipe 81 is buried and laid in the ground, for example, and the sewage in the sewage tank 80 can be pumped toward the fermentation house 10 via a pump 88. . 2 and 3, this sewage pipe 81 is connected to a spray pipe 78 supported by a support column 76 fixedly arranged on the ceiling in the fermentation house and suspended in the longitudinal direction of the fermentation house 10. ing. As a result, the sewage is pumped into the spray pipe 78, and the sewage is sprayed from the spray hole toward the garbage in the fermenter 12 below. Here, the air having the odor component produced by aerobic fermentation of the garbage in the fermenter 12 is released to the atmosphere after deodorization by the deodorizing means, and further, the sewage discharged from the garbage carried into the treatment facility. Sprinkles from the top of the newly added daily garbage to promote the fermentation of the fermenting bacteria so that no odorous component gases or liquids are discharged outside. In the site map of FIG. 8, 84 is an arbitrary green zone.
[0026]
Next, although the effect | action of the garbage processing system which concerns on embodiment is demonstrated, the garbage processing method of this invention is demonstrated simultaneously with description of the effect | action. In this garbage treatment system, first, fermenting compost fertilized by inoculating inoculums such as actinomycetes in advance into fermenter 12 and fermented and decomposed, for example, to about 70 percent by volume ratio of the fermenter is filled. deep. Then, the garbage and the moisture adjusting material are evenly spread over the fermentation compost in the fermenter 12 in a planar shape.
[0027]
Garbage generally retains moisture at a moisture content of 80 to 90 percent, and this moisture adjustment is one of the factors that greatly determine the fermentation efficiency in the fermenter 12. That is, the moisture adjusting material is spread evenly on the fermented compost in the fermenter at a ratio of 1 to the garbage 2.
[0028]
As the moisture adjusting material, for example, bark, bran, wood scrap, sawdust, and other decomposable organic substances having a low water content are used, and those having a water content of about 10 percent are advantageously used. Therefore, when these moisture adjusting materials and garbage are added at a ratio of about 2 to 1, the moisture content of the garbage itself is adjusted to about 60% as a whole.
[0029]
And, if the mixing and stirring action is performed several times a day by the stirring device 38 while supplying air directly from the air supply pipe 20 provided in the fermenter 12, that is, supplying oxygen, it is appropriate. While mixing the fermented compost accumulated up to the previous day by the reversal of the waste and the garbage thrown in that day, oxygen was supplied by the air supply pipe 20 and was taken in through the vent 22 on the indoor side of the fermentation house 10. Oxygen is supplied to the outside air from the surface side of the garbage, and the organic matter is reliably fermented while maintaining good fermentation conditions of the garbage.
[0030]
At this time, the air blower 23 is installed in the fermentation house 10 so that the air blower 23 is sucked from the air in the fermentation house, and the air blower 23 and the air supply pipe 20 are connected in communication. The air in the house is recirculated while supplying oxygen directly to the garbage in the fermentation bed by the air blower 23 and the air supply pipe 20 as indoor reflux means.
[0031]
Furthermore, at this time, fresh outside air is taken into the fermentation house 10 through the vent hole 22 provided in the fermentation house 10 by constantly maintaining the pressure in the fermentation house 10 at a negative pressure by the suction action by the suction means 24. Since it is in a ventilated state, the atmosphere suitable for the fermentation conditions is maintained in a certain dry state together with fresh oxygen supply by suppressing the high temperature and humidity state in the fermentation house 10.
[0032]
That is, the fermentation temperature by aerobic fermentation rises to, for example, about 70 ° C. in the garbage that is being composted, and a large amount of water vapor is gasified by the heat of fermentation and filled in the fermentation building. Becomes hot and humid, giving rise to conditions that hinder fermentation for fermenting bacteria.
[0033]
In this respect, in the garbage processing system of the present invention, as described above, fresh fresh air is always taken in from the vent hole 22 as a venting means while making the inside of the fermentation house have a negative pressure. To maintain the suitable fermentation conditions for the fermenting bacteria. In particular, in this embodiment, since the wall member constituting the fermentation building 10 is constructed from a light-transmitting material, for example, the fermentation building room is always kept warm even in winter when there is little sunlight. If necessary, outside air is taken in so that the fermentation conditions can be easily maintained by ventilation. For example, under excessive sunshine conditions such as summer time, for example, an excessively high temperature state can be corrected by simply attaching a cold ridge or the like to the roof surface.
[0034]
As described above, according to the garbage processing system and method of the present invention, the fermenter 12 for charging garbage, the stirring means (38), and the air supply in the fermentation house 10 whose room is sealed. The tube 20, the aeration means, the suction means 24, the deodorizing means 26, and the air blower 23 are provided so as to take in air while constantly maintaining the inside of the fermentation building in a negative pressure state. It is possible to accept and process a large amount of garbage with a simple structure every day. For example, as shown in FIG. 10, when comparing the present invention with the conventional method in a table, the conventional incineration equipment cost of 100 million yen is required for garbage disposal per ton. In the present invention, a facility cost of 2.2 million yen is calculated for 1 ton of processing.
[0035]
In addition, while a conventional waste treatment machine conventionally requires an electric charge of 10,000 yen for 2 tons per day, the present invention depends on the volume of the fermenter for 1 day. In the example of the embodiment, 36 tons can be processed for one fermenter. It has been confirmed that the cost of electricity required for this is 2,000 yen. On the other hand, regarding the installation area, for the present invention, for example, 1350 square meters are required for a processing amount of 36 tons, whereas a commercially available processing machine requires an area of about 30 square meters for a processing capacity of 2 tons. It is. In the system of the present application, it is 75 square meters when converted per 2 tons of processing amount, and it is understood that the system of the present application has extremely high cost performance as compared with a conventional processor or the like. In addition, as mentioned above, gas and liquids containing no odor are not discharged to the outside. For example, such treatment facilities are installed in landfills of urban harbors distributed on the coastline. It is possible to install such a treatment facility at a low cost that does not impair its function even if the ground surface changes, etc., and to promote extremely effective use of a landfill facility at a landfill site.
[0036]
Note that the garbage processing system and the processing method thereof according to the present invention are not limited to the above-described embodiments, and arbitrary modifications are made without departing from the essence of the invention described in the claims. It is good.
[0037]
For example, the size of the fermentation house or the fermenter may be any size or volume, and a larger number of deodorization tanks may be installed to improve the deodorization efficiency. Moreover, the mixing | blending ratio of the water | moisture-content adjustment material with respect to garbage is set as what has a certain amount of width | variety like 1 to 1 to 2 to 1, for example.
[0038]
