However, since the troubled trees are finely crushed, the processing cost is high. In addition, since composting takes a long time, a large area is required for composting. And for farmers who use compost, the cost of fertilizer is high and the demand is small for the above reasons. Therefore, at present, there is no emission and demand of troubled trees. In addition, there is a method of burning a large amount of troubled trees such as thinned wood, but there is also an accident that fires spread to the adjacent forest and fire spread, so if it is discharged in large quantities, it is generally not possible due to environmental problems. It is. In addition, obstacle trees may be used for land reclamation, but it is difficult to use the landfill after the large amount is discharged due to softness or depression of the ground. In addition, even a small amount can be a source of termites. Although it is conceivable to convert the troubled tree into chips, papermaking chip materials are more expensive than imported materials, and pruned branches that do not become chips cannot be processed. In addition, dumping obstacle trees into forests means that heavy rain starts to flow into rivers,
It is dangerous because it blocks narrow waterways and causes flooding of rivers. Furthermore, dumping near roads causes forest fires due to tossing of cigarettes. On the other hand, in the first step of mixing pulp slag incineration ash with public sewage sludge to obtain a mixed raw material and in the second step of fermenting the mixed raw material, a malodor is generated from the mixed raw material, and the malodor is generated outside the facility. Leaked and there were environmental issues. Further, there is a step of applying aeration using an inclined surface when shifting from the first step to the second step. In the case of the aeration, the fermentation is promoted by contact of the mixed raw material with air, but a bad smell is also generated.

くことによるものである。The operation of the above means will be described. First, the pulp incineration ash immediately after being discharged from the incinerator of the paper mill has a high temperature of about 300 ° C. The temperature of the incinerated ash, which has been discharged and then comes into contact with the outside air, decreases.
It is transported by truck at around 80 ° C and brought to the manufacturing plant. Then, in the first step, the mixed raw material composed of sewage sludge, pulp incineration ash, wood grain, and wood vinegar is 10 t, 10 t, respectively.
Stir and mix at a rate of 3 liters, 40 liters. As a result, the raw material mixture emits a violent odor or an unpleasant odor in raw untreated sludge, but a considerable odor or the like is removed by the deodorizing function of pulp incineration ash or wood vinegar. Nevertheless, the off-flavors or off-flavors are not completely eliminated and the off-flavor effects remain. There, the smoke produced by burning the obstruction trees by the carbonization device, the primary fermentation facility and the secondary fermentation facility,
It is sent to the tertiary fermentation facility to fill it, and the mixed raw material in each facility is smoked to remove the remaining bad odor. The following results were obtained when an experiment was conducted on the removal of offensive odor by smoke. At a temperature of 25 ° C., 1.0 kl of the fermented sludge was put in a plastic bag, mixed well, and the volatile components were recovered in the air.
It was 6 ppm. The value of this concentration is a concentration at which the smell of ammonia is strongly felt even in the human nose. The obstacle tree was put in the carbonizer, and the smoke generated from the carbon tree was put in a plastic bag and stirred well. As a result, the smell of ammonia could not be felt in the human nose almost completely. Further, as measured by Gastec, the amount of ammonia is concentrated to about 10 times. The reason is that a large amount of ammonia is absorbed into the water droplets of water vapor contained in the smoke due to the nature of ammonia, and the deodorizing action of the wood vinegar component contained in the smoke acts.

The pulp incineration ash 3 immediately after being discharged from the incinerator of the paper mill has a high temperature of about 300 ° C. The temperature of the incinerated ash, which has been discharged and then comes into contact with the outside air, decreases. The temperature of the incinerated ash is lowered by showering the incinerated ash, transported by truck at about 60 to 80 ° C., and transported to a manufacturing plant. "First step" sewage sludge 2 and pulp ash 3 and Kitsubu 4 and pyroligneous 5 10t respectively, 10t, 3m 3, were stirred and mixed at a ratio 40 liters make a mixed raw material 1. The temperature of the mixed raw material 1 is kept around 40 ° C. As a result, the mixed raw material 1 emits a violent odor or an unpleasant odor in the raw untreated sludge 2, but a considerable odor or the like is removed by the deodorizing function of the pulp incineration ash 3 and the wood vinegar 5. Nevertheless, the off-flavor or off-flavor is not completely eliminated, and the off-flavor effect remains. There, the smoke generated by carbonizing the troubled tree by the carbonizing device 10 is sent to the primary fermentation facility and the secondary fermentation facility to be filled therein, and the mixed raw material in each fermentation facility is smoked to remove the remaining odor. The mixed raw material 1 is put into the primary fermentation facility 6 and deposited for about 5 days. Here, the water content of the mixed raw material 1 to be fermented is 50 to 55%.
Becomes "Second step" Inclined shoes arranged from high place to low place
The mixed raw material 1 is dropped into the secondary fermentation facility 8 through the second fermentation facility 8. The water content of 1-2% is scattered while sliding down the inclined stall. It should be noted that the fermentation is performed while the mixed raw material is exposed to air even during the sliding down due to the inclined shot. [Third Step] In the secondary fermentation facility 8 received through the inclined shout facility 7, the mixed raw material 1 is put into the scoop fermenter 81 and cut back for about 10 days.
The function of the fermenter 81 is to perform pulverization, agitation, and switching by a agitation mechanism, to sufficiently supply oxygen, and
Promotes fermentation. As a result, the water content is 43 in summer.
４０40%, winter 46-43%. "Fourth step" The mixed raw material 1 is fed from the secondary fermentation facility 8 to a hopper.
It is fed into the kiln-type fermentation machine of the tertiary fermentation facility 9 that has been received via the belt conveyor 13 and 13 and is adjusted to an average water content within 24 hours to remove unevenness. That is, the kiln-type fermentation machine further promotes the fermentation drying of the mixed raw material 1. "Smoke sending process by carbonization of obstacle tree" Carbonization device 10
Thus, the obstacle trees are carbonized to generate smoke, and supplied from the primary fermentation facility 6 of the first step to the secondary fermentation facility of the third step through the flue 12 to be filled. Raw material 1 is given a smoking effect. And the fourth
In the tertiary fermentation facility 9 of the process, when the smoke distributed from the flue 12 is supplied to the exhaust gas outlet 91, the smoke is discharged while being mixed with the exhaust gas generated from the kiln type fermenter.
Charcoal and wood vinegar are produced together with the smoke generated by carbonizing the troubled trees in the carbonizing apparatus 10. Therefore, the charcoal and wood vinegar are used as the mixed raw material 1 in the first step. In addition, since the primary fermentation facility 6 and the secondary fermentation facility 8 are connected by a tunnel-shaped inclined shot facility 7,
When the smoke is distributed and supplied from the carbonization device 10 to both the fermentation facilities 6 and 8, the smoke spreads and fills the tunnel type inclined shout facility 7 as well. "Fifth step" The compost obtained from the mixed raw material in the fourth step is sent to the measuring device 16 by the belt conveyor 15, weighed, packed in the bag body 11, and kept ready for shipment. Then, the fermentation is performed in the bag during the standby.

By sending the waste gas into each facility through a flue and filling it, the mixed raw material is smoked and the odor generated from the sludge can be removed. Further, in the kiln-type fermentation machine, when the smoke is supplied to the exhaust gas exhaust port, the smoke is mixed with the exhaust gas, and the exhaust gas can be discharged while removing the offensive odor. Therefore, conventionally, a large amount of troubled wood is treated by a carbonization device such as a charcoal kiln to generate smoke, and the smoke is supplied to each fermentation facility in a large amount to be filled, and the charcoal and wood vinegar obtained by carbonization are mixed. By using it as a raw material, the troubled trees can be effectively used without waste, and the environmental problems of traders and local governments can be solved. In addition, the use of smoke for sludge treatment makes deodorization more reliable, thereby achieving environmental preservation. This method is novel and useful as a sludge odor removing method and apparatus using such kind of obstructed trees. In mountainous areas, there is a new occupation as a new type of job as an effective use of obstacle trees generated in large quantities. It is expected to be connected and economic effects can be expected.

臭作用が働くことによるものである。The operation of the above means will be described. First, pulp incineration ash immediately after being discharged from an incinerator of a paper mill has a high temperature of about 300 ° C. self-heating. Then, the temperature of the incinerated ash that has come into contact with the outside air after being discharged decreases.
Transport by truck at around 80 ° C and bring it to the manufacturing plant. Then, in the first step, the mixed raw material composed of sewage sludge, pulp incineration ash, wood grain, and wood vinegar is 10 t, 10 t, respectively.
Stir and mix at a rate of 3 liters, 40 liters. As a result, the raw material mixture emits a violent odor or an unpleasant odor in raw untreated sludge, but a considerable odor or the like is removed by the deodorizing function of pulp incineration ash or wood vinegar. Nevertheless, the off-flavors or off-flavors are not completely eliminated and the off-flavor effects remain. There, the smoke produced by burning the obstruction trees by the carbonization device, the primary fermentation facility and the secondary fermentation facility,
It is sent to the tertiary fermentation facility and filled, and in each facility
Eliminate the foul odor generated from the mixed raw materials or smoke the mixed materials
This removes the remaining bad odor. The following results were obtained when an experiment was conducted on the removal of offensive odor by smoke. Fermentation sludge 1.0 at 25 ℃
kl was put in a plastic bag, mixed well, and the volatile components were collected in the air and measured with a gas technician. As a result, the ammonia concentration was 16 ppm. The value of this concentration is a concentration at which the smell of ammonia is strongly felt even in the human nose. The obstacles were put in a carbonizer, and the smoke generated there was put in a plastic bag and mixed well. As a result, the smell of ammonia was no longer perceived in human nose. Further, as measured by Gastec, the amount of ammonia is concentrated to about 10 times. The reason is that a large amount of ammonia is absorbed into the water droplets of water vapor contained in the smoke due to the nature of ammonia, and the deodorizing action of the wood vinegar component contained in the smoke acts.

The pulp incineration ash 3 immediately after being discharged from the incinerator of the paper mill has a high temperature of about 300 ° C. self-heating. Then, the temperature of the incinerated ash that has been discharged and then comes into contact with the outside air decreases. However, the temperature of the incinerated ash is lowered by showering the incinerated ash, transported by truck at about 60 to 80 ° C., and transported to a manufacturing plant. "First step" A mixed raw material 1 is prepared by stirring and mixing sewage sludge 2, pulp incineration ash 3, main grains 4 and wood vinegar 5 at a ratio of 10 t, 10 t, 3 m 3 and 40 liters, respectively. The temperature of the mixed raw material 1 is kept around 40 ° C. As a result, the mixed raw material 1 emits a violent odor or an unpleasant odor in the raw untreated sludge 2, but a considerable odor or the like is removed by the deodorizing function of the pulp incineration ash 3 and the wood vinegar 5. Nevertheless, the off-flavor or off-flavor is not completely eliminated, and the off-flavor effect remains. There, the smoke generated by carbonizing the obstruction trees by the carbonizing device 10 is sent to the primary fermentation facility and the secondary fermentation facility to be filled therein, and the fermentation facilities are filled therein .
To remove the odor generated from the mixed raw material
Removes the remaining bad smell by being smoked. The mixed raw material 1 is put into the primary fermentation facility 6 and deposited for about 5 days. Here, the water content of the mixed raw material 1 to be fermented is 50.
~ 55%. "Second step" The mixed raw material 1 is dropped to the secondary fermentation facility 8 through the inclined chute facility 7 arranged from a high place to a low place. While sliding down the inclined chute, a water content of 1 to 2% is scattered. The fermentation is performed while the mixed raw material is exposed to air even during the sliding down by the inclined chute. "Third Step" In the secondary fermentation facility 8 received through the inclined chute facility 7, the mixed raw material 1 is put into the scoop fermenter 81 and cut back for about 10 days.
The function of the fermenter 81 is to perform pulverization, agitation, and switching by a agitation mechanism, to sufficiently supply oxygen, and
Promotes fermentation. As a result, the water content is 43 in summer.
４０40%, winter 46-43%. "Fourth step" The mixed raw material 1 is fed from the secondary fermentation facility 8 to the kiln-type fermentation machine of the tertiary fermentation facility 9 which has been received via the hopper 13 and the belt conveyor 14 and adjusted to an average water content within 24 hours. To remove unevenness. That is, the kiln-type fermentation machine further promotes the fermentation drying of the mixed raw material 1. "Smoke sending process by carbonization of obstacle tree" Carbonization device 10
Thus, the obstacle trees are carbonized to generate smoke, and supplied from the primary fermentation facility 6 of the first step to the secondary fermentation facility of the third step through the flue 12 to be filled. Raw material 1 is given a smoking effect. And the fourth
In the tertiary fermentation facility 9 of the process, when the smoke distributed from the flue 12 is supplied to the exhaust gas outlet 91, the smoke is discharged while being mixed with the exhaust gas generated from the kiln type fermenter.
Charcoal and wood vinegar are produced together with the smoke generated by carbonizing the troubled trees in the carbonizing apparatus 10. Therefore, the charcoal and wood vinegar are used as the mixed raw material 1 in the first step. In addition, since the primary fermentation facility 6 and the secondary fermentation facility 8 are connected by the tunnel-shaped inclined chute facility 7,
When the smoke is distributed and supplied from the carbonization device 10 to both the fermentation facilities 6 and 8, the smoke spreads and fills the tunnel type inclined chute facility 7 as well. "Fifth step" The compost obtained from the mixed raw material in the fourth step is sent to the measuring device 16 by the belt conveyor 15, weighed, packed in the bag body 11, and kept ready for shipment. Then, the fermentation is performed in the bag during the standby.

果が期待できる。According to the present invention having the above-described structure, smoke generated by carbonizing an obstruction tree with a carbonization device in a public sludge treatment plant or in each facility for fermenting sludge and human waste generated from homes. Odors generated from mixed raw materials by removing and filling the facilities through the flue
Or remains after the mixed raw material is smoked
The odor can be removed. Further, in the kiln-type fermentation machine, when the smoke is supplied to the exhaust gas exhaust port, the smoke is mixed with the exhaust gas, and the exhaust gas can be discharged while removing the offensive odor. Therefore, a large amount of troubled wood is treated by a carbonization device such as a charcoal kiln to generate smoke, and the smoke is supplied to each fermentation facility in a large amount to be filled, and the charcoal and wood vinegar obtained by carbonization are mixed into a raw material. By using it, the troubled trees can be effectively used without waste, and the environmental problems of the dealers and local governments can be solved. Moreover, the use of smoke for sludge treatment makes deodorization more reliable, so that environmental preservation can be achieved, and a conventional deodorizing device is not required, so that management costs for the deodorizing device can be omitted. Therefore, the present invention is novel and useful as a method and an apparatus for removing the offensive odor of sludge using this kind of obstacle tree. In addition, in the forest area, there is a new occupation as a new type of job as an effective use of the obstacle trees generated in large quantities, and it becomes a countermeasure for special slope workers during off-season such as winter.
It is expected that this will lead to the average work of workers, and economic effects can be expected.
