DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for decomposing organic wastes such as garbage, manure, and industrial waste discharged from a food processing factory by utilizing the action of microorganisms. About.

[0002]

2. Description of the Related Art When treating organic waste such as garbage, manure, and industrial waste discharged from food processing factories, organic microorganisms are used instead of conventional incineration and ocean dumping. Treatment methods for decomposing waste have been adopted. In the treatment of organic waste using microorganisms, a microbial carrier carrying microorganisms such as sawdust and wood chips and organic waste are placed in a horizontal treatment container equipped with spiral stirring blades inside, and the microorganisms are treated. The carrier and the organic waste are simultaneously moved to the left and right by the stirring blades in an environment where the activity of the microorganisms is activated, and the organic waste is sufficiently mixed with stirring and allowed to stand. And decompose into water. In a method using such a horizontal processing apparatus in which the microorganism carrier and the organic waste are forcibly transferred and stirred in the horizontal direction, the organic waste can be almost completely decomposed in several tens of hours. .

However, in the conventional horizontal treatment apparatus, if strong stirring is performed to increase the stirring efficiency between the microorganism carrier and the organic waste, the microorganism carriers rub against each other and are damaged, so that the ability to carry microorganisms is rapidly increased. And the ability to treat organic waste is also reduced. for that reason,
It is necessary to reduce the stirring power to some extent and perform stirring.
If the stirring power is too weak, there arises a problem that it is difficult to uniformly stir the carrier and the organic waste in the container in an ideal state. In addition, in the horizontal processing apparatus, the area occupied by the apparatus generally becomes large, and there is a problem that the installation becomes difficult when the installation place is restricted. In order to solve these problems, a vertical processing apparatus has been developed in which the microorganism carrier and the organic waste are stirred while being forcibly transferred in a vertical direction.

[0004]

However, in the conventional vertical treatment apparatus, since the organic waste input portion is provided at the upper portion, the organic waste only falls by itself. The mixing efficiency with the waste is extremely low, and there is a problem that a long time treatment is required to decompose the organic waste. In addition, due to the low mixing efficiency of the microorganism carrier and the organic waste, the fluidity of the microorganism carrier in the processing vessel is reduced, causing problems such as segregation, solidification, and adhesion of the microorganism carrier to the inner wall of the processing vessel. Easy to do. Further, since the mixing efficiency of the microorganism carrier and the organic waste is low, a large amount of the organic waste cannot be stably treated in a short time.
Therefore, in order to process a large amount of organic waste in a short time, it is necessary to install a pretreatment device for uniformly mixing the microorganism carrier and the organic waste in advance. This leads to problems such as an increase in the installation cost of the waste treatment apparatus and an increase in the processing cost due to the increase in the number of processing steps. The present invention has been made in view of such circumstances, and has a high mixing efficiency of a microorganism carrier and an organic waste, and can stably treat a large amount of organic waste in a short time without performing pretreatment. An object of the present invention is to provide a waste treatment method and an organic waste treatment apparatus using the same.

[0005]

According to the present invention, there is provided a method for treating an organic waste, comprising the steps of vertically separating a crushed organic waste and a microorganism carrier carrying microorganisms that decompose the organic waste. In the method for treating organic waste in which the organic waste is decomposed by being mixed after being put in a mold container, a transport cylinder having a stirring feeder provided therein is disposed in a central portion of the vertical container. Then, the microorganism carrier containing the organic waste is sent from a lower portion of the vertical container to an upper portion to form a circulating flow of the microorganism carrier in the vertical container, and a lower portion is formed from an intermediate portion of the vertical container to a lower portion. The organic waste is forcibly conveyed into the vertical container by one or more forcible conveying means provided in the container.

[0006] The microorganism carrier containing organic waste existing in the lower part of the vertical container becomes an upward flow in the transport cylinder by the stirring feeder, and is pushed out of the transport cylinder at the upper part of the transport cylinder. A circulating flow is formed in the vertical container outside the transfer cylinder, which is a downward flow due to natural fall. Here, since the organic waste is forcibly charged by the forced conveying means into the lower part of the vertical container where the transfer of the microorganism carrier by the stirring feeder is started, the organic waste is disturbed without disturbing the flow state of the circulating flow of the microorganism carrier. Sexual waste can be combined with the microbial carrier in transit. Here, in the method for treating organic waste of the present invention, the microorganism carrier moving from the upper part to the lower part of the vertical container by one or more mixing feeders provided from the middle part to the lower part of the vertical container. Is preferably forcibly conveyed to the inlet side provided at the lower part of the transfer cylinder. By forcibly transporting a part of the microorganism carriers that have fallen and accumulated on the outside of the transport cylinder to the inlet side provided at the lower part of the transport cylinder by one or more mixing feeders, The mixture of the microorganism carrier and the organic waste transferred from the lower part of the vertical container by the stirring feeder can further mix the microorganism carrier with the mixture. Since the microorganism carrier is forcibly transported to the inlet portion of the transport cylinder before the upward flow is formed inside the transport cylinder, the microorganism carrier during transfer of the microorganism carrier without disturbing the state of the upward flow. It can be mixed into a mixture with organic waste.

In accordance with the object of the present invention, there is provided an apparatus for treating organic waste, comprising: a microorganism carrier carrying microorganisms that decompose organic waste; and a vertical container for storing and treating the organic waste. An organic waste treatment device having a transport cylinder provided with a stirring feeder provided in a central portion of the vertical container, forcibly transporting the organic waste into the vertical container. A forced transfer means for performing the forced transfer of the microbial carrier moving from the upper portion to the lower portion of the vertical container to an inlet side of the lower portion of the transfer cylinder, the forced transfer device being provided at a lower portion of the vertical container. Is provided from the middle part to the lower part of the side wall of the vertical container.

[0008] By using the forced conveying means, the organic waste can be continuously charged into the vertical container little by little. Further, since the organic waste is forcibly charged into the transport stream of the microorganism carrier, the transport stream of the microbial carrier and the organic waste can be effectively combined and mixed. Also, since one or more mixing feeders are provided from the middle part to the lower part of the side wall of the vertical container, by combining and driving these mixing feeders and the stirring feeder, the microorganism carrier and the organic waste by the stirring feeder are driven. The transfer flow of the mixture with the product and the transfer flow of the microorganism carrier by the mixing feeder can be efficiently mixed at the entrance of the transfer cylinder. Furthermore, since the mixing is performed at the inlet of the transport cylinder, the state of the upward flow of the microorganism carrier containing organic waste is not disturbed.

As shown in FIG. 1, the vertical container 11 has, for example, an upper wall portion 16 having a cylindrical shape, and is connected to the upper wall portion 16 and is tapered to have a diameter decreasing toward a lower end. A tapered side wall portion 17, a lower side wall portion 18 connected to the tapered side wall portion 17, an upper lid 19 attached to the upper side wall portion 16, and a lower lid 20 attached to the lower side wall portion 18. Have. The vertical container 11 is formed of, for example, a stainless steel plate in consideration of corrosion resistance. Since the intermediate portion of the vertical container 11 has the tapered side wall 17, the microorganism carrier and the organic waste can be moved along the inner surface of the tapered side wall 17 and accumulated on the bottom of the vertical container 11. it can.

The transport cylinder 13 is made of, for example, stainless steel (SUS304) in consideration of corrosion resistance and wear resistance, and is provided on the inner cylindrical portion 21 and the upper lid 19 to support the inner cylindrical portion 21. And an agitating feeder 12 inserted through the inner cylindrical portion 21 and the outer cylindrical portion 22.
And The stirring feeder 12 includes, for example, a rotating shaft 23 and a spiral blade 24 attached to the rotating shaft 23.
And one end 25 of the rotating shaft 23 is
, And the other end 26 extends to the upper portion of the outer cylindrical portion 22 provided on the upper lid 19. The other end 26 is connected to a speed reducer 29 fixed to a mounting plate 28 provided above the outer cylindrical portion 22 via a connection mechanism 27 such as a flange, for example. Is connected to an electric motor 30 provided above the speed reducer 29. The spiral blade 24 is provided over a section from one end 25 of the rotating shaft 23 to almost the center of the height of the outer cylindrical portion 22. A plurality of openings 31 are provided on the side wall of the outer cylindrical portion 22.

When the electric motor 30 is rotated and the rotating shaft 23 is rotated by the speed reducer 29 at a rotation speed of, for example, 15 to 20 rpm, the microorganism carrier containing organic waste accumulated on the bottom of the vertical container 11 is rotated. Moves while being scraped up by the spiral blade 24, and the inner cylindrical portion 21 and the outer cylindrical portion 22
Moving while ascending inside. The microorganism carrier that has risen to the height of the outer cylindrical portion 22 is pushed out of the outer cylindrical portion 22 through a plurality of openings 31 provided on the side wall of the outer cylindrical portion 22, falls naturally, and falls into the vertical container 11 again. accumulate.
Thus, by providing the transport cylinder 13 at the center of the vertical container 11, the vertical container 1
A circulating stream consisting of a microbial carrier containing organic waste can be formed from the bottom to the top of 1.

Subsequently, it is provided on a side portion of the lower wall portion 18,
The screw charging mechanism 14 for forcibly transporting organic waste into the vertical container 11 will be described. As shown in FIG. 3, the screw-type charging mechanism 14 includes a hopper 32 for storing organic waste, a crusher 34 driven by an electric motor 33, and an organic waste crushed by the crusher 34. A transport unit 35 forcibly transporting the mold into the mold container 11, and a transport unit 35
Motor 36 with a speed reducer, which is an example of a driving device for driving the motor
And The transport section 35 includes a rotating shaft 37 and a spiral blade 38 attached to the rotating shaft 37.
The screw-type charging mechanism 14 is mounted on an installation table 39 on which the vertical container 11 is installed.

The organic waste crushed by the crusher 34 is sent to a transport section 35, and a spiral blade 38 attached to a rotating shaft 37 provided in the transport section 35 and driven to rotate by an electric motor 36.
The vertical container 11 moves around the rotation axis 37 by the rotation of
It is charged at the bottom of. The lower part of the vertical container 11 is a position where the microorganism carrier is swept up by the spiral blades 24 of the stirring feeder 12 and starts a swiveling motion around the rotation axis 23, in a direction orthogonal to the upward flow of the microorganism carrier. Since the organic waste is loaded into the vertical container 11 from the transport unit 35, the organic waste can be effectively combined with the upward flow and mixed. That is, by combining the organic waste with the microbial carrier at a stage prior to the formation of the circulating flow of the microbial carrier containing the organic waste, the organic material can be dispersed without disturbing the flow of the circulating flow of the microbial carrier. Waste can be absorbed into the microbial carrier stream.

Next, one or more mixing feeders 15 provided on the tapered side wall portion 17 for forcibly transporting the microorganism carrier to the lower inlet side of the transport cylinder 13 will be described. As shown in FIG. 2, for example, six mixing feeders 15 are provided at equal intervals on the circumference of the tapered side wall 17. As the mixing feeder 15, for example, a screw-type feeder having a spiral blade 42 provided on a rotating shaft 41 connected to a motor 40 with a speed reducer can be used. The rotation shaft 41 of each mixing feeder 15 is mounted to face the axis of the rotation shaft 23, and the electric motor 40 is driven to rotate the spiral blades 42 provided on the rotation shaft 41, thereby rotating the microorganism carriers existing around the rotation. It can be transported to the inlet side provided at the lower part of the transport cylinder 13 along with the flow around the shaft 41.

The flow of the microorganism carrier conveyed as a flow around the rotary shaft 41 to the inlet side provided at the lower portion of the transport cylinder 13 rises from the lower portion of the vertical container 11 around the rotary shaft 23 by the stirring feeder 12. It joins from a direction orthogonal to the flow of the mixture of the microorganism carrier and the organic waste transferred as a stream. For this reason, the microorganism carrier can be further mixed with the mixture of the microorganism carrier and the organic waste by collision of the two streams. Since the microorganism carrier is forcibly transported to the inlet portion of the transport cylinder 13 where the upward flow is formed, the microorganism carrier containing the organic waste being transferred is efficiently transferred without disturbing the state of the upward flow. They can be combined and mixed.

Next, a method of treating organic waste by the organic waste treatment apparatus 10 will be described. First, sawdust, which is an example of a microorganism carrier that carries microorganisms that decompose organic waste, and microorganisms that decompose organic waste, for example, aerobic high-temperature bacteria, are provided in the upper lid 19 in the vertical container 11. From the inlet (not shown) to adjust the humidity to a humidity environment in which microorganisms are activated. Then, the electric motor 30
Is driven to rotate the rotating shaft 23 so that the spiral blade 2
4 is rotated to mix the sawdust and the microorganisms that have been thrown into and accumulated in the vertical container 11 while being lifted up by the spiral blades 24 and move upward, and the inner cylindrical portion 21 and the outer cylindrical portion 22 are moved upward. Is moved as an upward flow. The mixture of sawdust and microorganisms that has risen to the outer cylindrical portion 22 is pushed out of the outer cylindrical portion 22 through a plurality of openings 31 provided on the side wall of the outer cylindrical portion 22, falls naturally, and falls vertically.
1 again. By forming such a circulating flow sent from the lower part to the upper part of the vertical container 11, the sawdust and the microorganisms are uniformly mixed to produce sawdust to which the aerobic thermophilic bacteria have settled (hereinafter referred to as microorganism carrier).

Next, a method for charging the organic waste into the vertical container 11 will be described. While the stirring feeder 12 is driven to form a circulating flow of the microorganism carrier in the vertical container 11, for example, while the six mixing feeders 15 are operated one by one sequentially for a predetermined time, the screw-type charging mechanism 14 is operated. By operating intermittently for a predetermined time, the crushed organic waste is charged into the vertical container 11 from the side of the lower wall portion 18 of the vertical container 11. Since the stirring feeder 12 is operating, the microorganism carrier is lifted up by the spiral blade 24 from the bottom of the vertical container 11 and rises. At this time, the crushed organic waste charged from the direction perpendicular to the upward flow by the screw charging mechanism 14 is mixed with the flow moving from the outside to the inside, and finally mixed. Entrained in the ascending flow and mixed well with the microbial carrier. Since the screw-type charging mechanism 14 operates intermittently, the crushed organic waste can be surely combined with the ascending flow of the microorganism carrier little by little.

The mixed flow of the crushed organic waste and the microorganism carrier is supplied to the inner cylindrical portion 21 which is the inlet portion of the transport cylinder 13.
Of the inner cylindrical portion 21
The microorganism carrier moving from the upper part to the lower part of the vertical container 11 is forcibly conveyed toward the lower opening of the inner cylindrical part 21 by one mixing feeder 15 being driven just before entering. The forced conveying flow by the mixing feeder 15 is in a direction orthogonal to the mixed flow of the crushed organic waste and the microorganism carrier constituted by the stirring feeder 12,
Riding on the flow moving from the outside to the inside while being efficiently stirred by the collision of the two flows, it is finally taken into the ascending flow by the stirring feeder 12, and the microbial carrier becomes the crushed organic waste and the microorganism. It will be well mixed with the mixed stream with the carrier.

Since six mixing feeders 15 are sequentially driven one by one for a predetermined time, an irregular flow of the microorganism carrier toward the rotating shaft 23 of the stirring feeder 12 is formed. Therefore, the microorganism carrier can be more effectively mixed with the ascending flow of the mixture of the crushed organic waste and the microorganism carrier formed by the stirring feeder 12. Since the microorganism carrier is forcibly transported to the inlet portion (lower opening of the inner cylindrical portion 21) of the transporting cylindrical body 13 before the upward flow of the mixture is formed, the inner cylindrical portion 2
The microbial carrier can be combined with the mixture of the crushed organic waste and the microbial carrier in transit without disturbing the state of the upflow formed inside 1.

When the charging of the crushed organic waste into the vertical container 11 is completed and the uniform mixing of the microorganism carrier and the crushed organic waste is completed, the screw type charging mechanism 14 is used. To stop. Further, the mixing feeder 15 and the stirring feeder 12 are stopped after being driven for a predetermined time, respectively. During standing, the organic waste is gradually decomposed by microorganisms, and the microorganisms obtain nutrients called organic waste and propagate in sawdust. The stirring feeder 12 and the mixing feeder 15 are intermittently driven in order to increase the efficiency of decomposition by microorganisms.

Next, a specific method of using the organic waste treatment apparatus 10 will be described. (1) Preparation operation An aerobic thermophilic bacterium, which is an example of a microorganism that decomposes organic waste, is introduced into the vertical container 11 from an input port (not shown) provided in the upper lid 19 of the vertical container 11. I do.
The sawdust to be charged is about 6 m ³ for the treatment of 500 kg / day of organic waste. The microorganisms are more active in slightly humid conditions, so the sawdust should be slightly moistened. After closing the inlet, the agitation feeder 12 is driven to sufficiently mix the sawdust and the aerobic thermophilic bacteria to cause the aerobic thermophilic bacteria to adhere to the sawdust (produce a microbial carrier).

(2) Charging of Organic Waste Garbage was used as an example of organic waste. When the daily processing amount is 500 kg, 250 kg is charged into the vertical container 11 twice. For example, the first charging is performed at 9:00 am, and the second charging is performed at 7:00 pm In the first charging of the organic waste, six stirring feeders 12 are further installed in a state where the stirring feeder 12 is driven at a rotation speed of, for example, 20 rpm to form a circulating flow of the microorganism carrier in the vertical container 11. The mixing feeders 12 are sequentially driven one by one, for example, in a clockwise order for 5 minutes.
, And the screw-type charging mechanism 14 is intermittently driven, for example, for 1 minute each, so that the organic waste crushed into the vertical container 11 is reduced to about 1. Charge for 5 hours. When the charging is completed, the driving of the screw type charging mechanism 14 is stopped. The mixing feeder 15 and the stirring feeder 12 are preferably operated continuously after completion of the charging of the organic waste from the viewpoint of improving the mixing efficiency and the stirring efficiency. However, the intermittent operation is performed from the viewpoint of energy saving. Specifically, the mixing feeder 15 is driven for an additional 2.5 hours after charging of the crushed organic waste is completed, and then stopped, and thereafter, the stop for 1.5 hours and the driving for 1.5 hours are repeated. . The stirring feeder 12 is driven for an additional hour after charging of the crushed organic waste is completed, and then the number of rotations is reduced to one.
After lowering by 5 rpm, the drive is stopped for another 1.5 hours, and thereafter, the drive is repeated at 1.5 rpm for 15 hours at 1.5 rpm and stopped for 1.5 hours. Further, the second charging of the organic waste is performed in the same manner, but the stirring feeder 12 is further driven for one hour after the charging of the crushed organic waste is completed, and then the rotation speed is reduced by 15 rpm and further reduced by one. After driving for 0.9 hours, the operation is stopped. After that, driving for 15 hours at 1.9 rpm and stopping for 1.5 hours are repeated.

(3) Treatment of Organic Waste The decomposition state of garbage by microorganisms is grasped by a thermometer (not shown) installed in the vertical container 11. When the garbage is charged, the decomposition of the garbage by microorganisms is started, and decomposition heat is generated. At the time when the decomposition of the organic waste becomes maximum, the temperature in the vertical container 11 becomes about 70 ° C., and then the temperature gradually decreases as the amount of the organic waste decreases, and finally the organic waste is removed. Recover to the temperature before charging. Therefore, by monitoring the temperature change in the vertical container 11, the decomposition state of the garbage can be grasped. From the temperature change behavior, it can be confirmed that almost all of the 250 kg of garbage charged at 9:00 am is decomposed by 7:00 pm of the second garbage charging.

The embodiment of the present invention has been described above.
The present invention is not limited to this embodiment,
For example, although a screw-type charging mechanism having spiral blades as the forced conveying means and a screw-type feeder as the mixing feeder are used, a pusher-type forced conveying means or a pusher-type mixing feeder may be used. Further, in the above-described embodiment, one forced conveying means is provided, but two or more forced conveying means may be provided. Further, sawdust was used as a microorganism carrier for carrying microorganisms that decompose organic waste, but wood chips, porous plastics, porous ceramics, and the like can also be used.
