Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a soot processing system and a processing method, for example, to purification treatment of pulverized soot drained after smashing soot together with an appropriate amount of water using a disposer.
[0002]
[Prior art]
When cooking, raw garbage such as vegetables and seafood, that is, straw is generated. These straws are pulverized together with an appropriate amount of water by, for example, a pulverizer called a disposer. Thus, pulverized culm drainage consisting of a mixture of pulverized culm and water is discharged from the disposer. Conventionally, for example, a system disclosed in Japanese Patent Application Laid-Open No. 9-155385 is known as a purification treatment system for pulverized wastewater. In the treatment system disclosed in this publication, fine garbage contained in pulverized wastewater is liquefied and decomposed by anaerobic treatment, and the wastewater after liquefaction is aerobically treated.
[0003]
[Problems to be solved by the invention]
In the conventional treatment system described in the above publication, a large amount of excess sludge is generated in the treatment tank because the wastewater obtained by liquefying and decomposing all the fine garbage is continuously treated by the activated sludge method. As a result, in the conventional treatment system, it was necessary to carry out the removal work of excess sludge regularly and fairly frequently. In addition, since all the fine garbage is liquefied and processed, the generated excess sludge is simply removed, and effective utilization of the fine garbage cannot be achieved.
[0004]
The present invention has been made in view of the above-mentioned problems, and it is not necessary to perform an operation for removing excess sludge, greatly reducing the maintenance burden on the system, and effective use of fine raw garbage and excess sludge generated by pulverization of soot. An object is to provide a bag processing system and a processing method that can be used.

DETAILED DESCRIPTION OF THE INVENTION
In the present invention, for example, pulverized culm drainage comprising a mixture of crushed pulverized by a disposer and an appropriate amount of water is temporarily stored in a storage tank. And among the pulverized wastewater stored in the storage tank, the solid-containing wastewater containing a lot of fine solids (that is, fine garbage) is transferred to the separation drying tank. In the separation / drying tank, fine garbage is separated and captured from the solid-containing wastewater introduced into the tank, the wastewater from which the fine garbage has been removed is returned to the storage tank, and the separated and collected fine garbage is dried. Thus, the obtained powdery dry garbage is effectively used as fuel, fertilizer, or the like. Or it is discarded by incineration. That is, in the present invention, it is possible to effectively use fine garbage generated by pulverizing the straw.
[0010]
On the other hand, liquid wastewater containing almost no fine garbage among pulverized wastewater is transferred to an activated sludge treatment tank. In the activated sludge treatment tank, liquid wastewater introduced into the tank is aerated and stirred together with activated sludge, and organic substances in the liquid wastewater are decomposed into carbon dioxide and water by the action of aerobic microorganisms in the activated sludge. Or it is microbialized (activated sludge). When aeration and stirring are stopped after sufficiently decomposing organic matter, activated sludge is precipitated, and a supernatant layer is formed thereon. Most of the supernatant layer is discharged to, for example, a sewer or a combined treatment septic tank. In addition, among the precipitated activated sludge, activated sludge other than the necessary sludge to be secured for the next aeration and stirring is returned to the storage tank as excess sludge. The surplus sludge returned to the storage tank is transferred to the separation / drying tank in the same manner as the fine garbage described above, and is subjected to a drying process after being separated and captured. Thus, only the necessary sludge remains in the activated sludge treatment tank. As described above, in the present invention, unlike the prior art, the work of removing excess sludge is basically unnecessary, and the maintenance burden on the system is greatly reduced.
[0011]
Embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a diagram schematically showing an overall configuration of a soot processing system according to an embodiment of the present invention.
The processing system of the present embodiment includes a disposer 1 for pulverizing raw garbage such as vegetables and seafood generated during cooking. The disposer 1 is attached to, for example, a kitchen sink or a top plate (worktop), and garbage is thrown into the inside through the inlet 1a. The input garbage is pulverized together with an appropriate amount of water supplied from, for example, water. In this way, the pulverized wastewater consisting of a mixture of pulverized fine garbage and water is discharged from the disposer 1.
[0012]
The pulverized wastewater discharged from the disposer 1 is guided to the storage tank 3 through the discharge pipe 2. An odor stop trap 2a is provided in the middle of the route of the discharge pipe 2.
The storage tank 3 has a bottom 3a formed to be inclined with respect to a horizontal plane. Therefore, the fine solid matter (that is, fine garbage) contained in the pulverized wastewater led to the storage tank 3 settles in the lowest region of the inclined bottom portion 3a. Waste water containing fine garbage deposited in the lowest region of the bottom 3 a is fed to the separation drying tank 5 through the transfer pipe 4.
[0013]
FIG. 2 is a diagram for explaining the configuration and operation of a transfer pipe that feeds wastewater containing fine garbage from a storage tank to a separation drying tank.
As shown in FIGS. 1 and 2, the one end 4 a of the transfer pipe 4 is positioned in the vicinity (that is, above) the lowest region of the inclined bottom 3 a of the storage tank 3. In addition, air 6a is supplied to the vicinity of one end 4a of the transfer pipe 4 through another pipe 6 (not shown in FIG. 1). Therefore, when the air 6a is sent into the transfer pipe 4 through the pipe 6, the waste water containing fine garbage is sucked up from the one end 4a of the transfer pipe 4 by a so-called air lift effect, and the mixture 4b of this waste water and air is It is pumped from the storage tank 3 to the separation drying tank 5. At this time, since the waste water containing a lot of fine garbage is pumped as a mixture with air, it is surely guided to the separation drying tank 5 without clogging in the middle of the transfer pipe 4.
[0014]
FIG. 3 is a diagram illustrating the configuration and operation of the separation drying tank. FIG. 4 is a diagram showing in detail the configuration of the solid material capturing body housed in the separation / drying tank, and (a) is a cross-sectional view along a plane perpendicular to the shaft portion. b) is a side view along a plane including a shaft portion.
As shown in FIG. 3, a large number of solid material capturing bodies 7 for capturing fine solid materials (garbage) contained in the wastewater fed from the storage tank 3 are stored in the separation drying tank 5. ing. As shown in FIG. 4, each capturing body 7 includes a rod-shaped shaft portion 41 and a large number of rod-shaped branch portions 42 that protrude radially outward from the shaft portion 41. In other words, each capturing body 7 has a hairbrush-like form as a whole. Specifically, the shaft portion 41 has, for example, a diameter of about 5 mm and a length of about 20 mm. Each branch portion 42 has a diameter of about 1 mm, for example, and a length of about 10 mm.
[0015]
Further, the separation / drying tank 5 is provided with a stirring mechanism 8 for stirring the waste water containing a lot of fine garbage fed from the storage tank 3 together with a large number of capturing bodies 7. The stirring mechanism 8 includes a rotating shaft portion 8a configured to rotate by the action of the motor 31, and several stirring members 8b extending radially outward from the rotating shaft portion 8a. Here, the rotary shaft portion 8a is set so as to extend substantially parallel to the bottom portion of the separation drying tank 5, and when the rotation shaft portion 8a rotates, the tip of each stirring member 8b is more than the bottom portion of the separation drying tank 5. It is configured to reach a slightly upper position. Therefore, when the stirring mechanism 8 is driven by the motor 31 and the rotating shaft portion 8a rotates, the waste water containing a large amount of fine garbage is stirred together with the many capturing bodies 7 by the action of each stirring member 8b. Further, as drying means, a hot air supply device 33 for supplying hot air, and pipes (19, 4) for guiding the hot air supplied from the hot air supply device 33 to the inside of the separation drying tank 5 are provided. I have.
[0016]
Further, the separation / drying tank 5 has a discharge pipe 9 for returning liquid wastewater remaining after the fine garbage is separated and captured from the wastewater containing a lot of fine garbage by a large number of capture bodies 7, and the capture body 7. A discharge pipe 10 is provided for guiding the powdered dry garbage obtained after the fine garbage separated and captured by the drying process to the storage tank 11. Here, on the discharge pipe 9 and the discharge pipe 10, on-off valves 9a and 10a are attached. In addition, the separation drying tank 5 and the discharge pipe 9 are arranged from the highest water level of the storage tank 3 so that the pulverized wastewater stored in the storage tank 3 does not flow backward to the separation drying tank 5 through the discharge pipe 9. Is installed at a sufficiently high position. Further, a collection bag 12 is detachably attached to the storage tank 11.
[0017]
On the other hand, of the pulverized wastewater stored in the storage tank 3, liquid wastewater containing almost no fine garbage deposited in the lowest region of the inclined bottom 3 a is transferred to the activated sludge treatment tank 14 via the transfer pipe 13. Be sent. Note that one end 13a of the transfer pipe 13 is the highest of the inclined bottom 3a of the storage tank 3 so that fine garbage contained in the pulverized wastewater is not fed to the activated sludge treatment tank 14 via the pipe 13. It is positioned near the area. The transfer pipe 13 is configured to supply liquid wastewater to the activated sludge treatment tank 14 using the air lift effect, similarly to the transfer pipe 4.
[0018]
FIG. 5 is a diagram for explaining the configuration and operation of an activated sludge treatment tank for treating activated sludge from liquid wastewater fed from a storage tank.
As shown in FIGS. 1 and 5, a partition plate 15 extending in the vertical direction from the bottom portion 14 a is formed inside the activated sludge treatment tank 14. A predetermined amount of necessary sludge is secured in one space 15a surrounded by the partition plate 15, the bottom portion 14a, and the side wall 14b of the processing tank 14. And in this space 15a, the diffuser pipe 17 for diffusing air in the processing tank 14 is installed in the vicinity of the bottom part 14a in order to aeration and stir the liquid waste water in the processing tank 14. An aeration pump 21 for supplying aeration air is connected to the aeration tube 17.
[0019]
Further, surplus sludge other than the necessary sludge secured in the space 15a settles above the other space 15b surrounded by the partition plate 15, the bottom 14a and the side wall 14b and the necessary sludge. Excess sludge that has settled above the space 15 b and the necessary sludge is fed to the storage tank 3 via the transfer pipe 16. Similar to the transfer pipe 4 and the transfer pipe 13, the transfer pipe 16 uses the air lift effect to reliably supply excess sludge as a mixture with air to the storage tank 3 without causing clogging. Further, a discharge pipe 18 for discharging the supernatant water obtained after aeration and stirring from the treatment tank 14 to the outside at any time is provided at a height position sufficiently spaced upward from the upper end of the partition plate 15. .
[0020]
Therefore, in the activated sludge treatment tank 14, as shown in FIG. 5A, the aeration pump 21 is operated and air is fed into the treatment tank 14 through the air diffusion pipe 17. The liquid wastewater is aerated and stirred together with the necessary sludge secured in the space 15a. As a result, the organic matter in the liquid wastewater is decomposed into carbon dioxide and water or is microbialized by the action of aerobic microorganisms in the activated sludge. The aeration pump 21 is configured to supply air as needed to the lower ends of the transfer pipe 4, the transfer pipe 13, and the transfer pipe 16, for example, via a switching valve.
[0021]
Next, as shown in FIG. 5 (b), after the organic matter has been sufficiently decomposed, when the air supply from the air diffuser 17 is stopped and aeration stirring is stopped, activated sludge is precipitated, A supernatant layer is formed. Most of the supernatant layer is discharged to the outside through the discharge pipe 18. As a result, the activated sludge layer 51 that has precipitated and the remaining portion 52 of the supernatant layer that has not been discharged through the discharge pipe 18 remain in the treatment layer 14. And as shown in FIG.5 (c), the activated sludge 53 settled in the space 15a is ensured for the next aeration stirring as a required sludge, and the activated sludge 54 overflowing from the space 15a is a surplus sludge of a supernatant layer. The remaining portion 52 is fed to the storage tank 3 via the transfer pipe 16. Thus, only the necessary sludge secured in the space 15a remains in the processing tank 14.
[0022]
The soot processing system of the present embodiment having the above configuration operates as follows. First, raw garbage such as vegetables and seafood is put into a disposable input port 1a for garbage that is installed separately from the drainage path of the kitchen. Then, after supplying an appropriate amount of tap water, the disposer 1 is operated to grind the garbage. The raw garbage pulverized by the disposer 1 becomes so-called pulverized wastewater, and flows into the storage tank 3 through the discharge pipe 2 with the odor stop trap 2a. Here, the pulverized wastewater is a mixture of crushed garbage and water, and is a wastewater containing a lot of fine solids.
[0023]
Among the pulverized wastewater that flows into the storage tank 3, fine garbage having a specific gravity higher than that of water immediately settles and collects in the lowest region of the inclined bottom portion 3a. On the other hand, fine garbage having a lighter specific gravity than water once floats on the water, but sinks into the drainage over time, and also collects in the lowest region of the bottom 3a.
In this state, when air is supplied from the aeration pump 21 to the lower end portion of the transfer pipe 4 through the switching valve, the waste water containing a large amount of fine garbage collected in the lowest region of the inclined bottom portion 3a is attracted by the air lift effect. It flows into the separation drying tank 5 without clogging. Moreover, since the mixture of water and air flows through the transfer pipe 4, the mixture automatically cleans the inside of the pipe, and the solid content hardly adheres to the inside of the pipe. This also applies to the other transfer pipes 13 and 16.
[0024]
Since the waste water flowing into the separation / drying tank 5 contains a large amount of fine garbage, in the initial state, the fine garbage concentrates in a part of the tank and causes a kind of blockage where water does not flow. Therefore, in order to eliminate this blockage state, the stirring mechanism 8 is operated, and the waste water in the tank is stirred together with a large number of capturing bodies 7. Thus, at first, a part of the fine garbage having a relatively large particle size is captured by the capturing body 7, and the liquid waste water from which the part of the fine garbage is removed returns to the storage tank 3 through the discharge pipe 9. When the stirring mechanism 8 is stopped after a lapse of a predetermined time and the transfer of the waste water from the storage tank 3 to the separation drying tank 5 is continued, the trapping body 7 that has already captured fine raw garbage having a large particle size and has become narrower is obtained. Gradually, fine garbage and excess sludge having a small particle diameter are also captured.
[0025]
In this way, by circulating the waste water between the storage tank 3 and the separation drying tank 5, fine garbage and excess sludge contained in the waste water are captured by the capturing body 7 with a good capture rate. In addition, the blockage may occur again during the circulation of drainage. In this case, the stirring mechanism 8 is driven, for example, about 1/4 turn so that the fine garbage and excess sludge do not return to the storage tank 3 via the discharge pipe 9 to eliminate the blocked state. The closed state can be detected using a water level sensor 32 (see FIG. 3) installed at a predetermined height in the separation / drying tank 5. After a predetermined time has elapsed, the operation of the aeration pump 21 is stopped to stop the circulation of the waste water, and the solid-liquid separation step in the separation / drying tank 5 is completed.
[0026]
When the solid-liquid separation step is completed, the on-off valve 9a of the discharge pipe 9 is closed, and in order to dry fine garbage separated and captured by the capturing body 7 and fine garbage remaining inside the separation drying tank 5, for example, 30 to While warm air of about 80 ° C. is sent into the separation drying tank 5, the stirring mechanism 8 is operated to stir the inside of the tank. The supply of warm air to the separation / drying tank 5 is performed via a pipe 19 having one end connected to a hot air supply machine 33 (see FIG. 3) and the other end connected to a midway path of the transfer pipe 4. Done. In this way, by stirring the inside of the tank while sending warm air into the separation / drying tank 5, the heat exchange property is improved and the drying time is shortened, and a large number of capturing bodies 7 are brought into contact with each other and dried. The garbage can be sufficiently removed from the capturing body 7 to regenerate the capturing performance of the capturing body 7.
[0027]
By the way, when drying is incomplete, heat exchange is performed in the tank, and the exchanged heat is used for evaporation of moisture. For this reason, the rise of the air temperature in a tank and the temperature of a tank main body is small. On the other hand, in a state where the drying is almost completely performed, the moisture in the tank is reduced, and the air temperature in the tank rises. That is, as the drying in the separation / drying tank 5 proceeds, the air temperature in the tank rises, and the temperature of the air discharged from the tank through the exhaust pipe 20 rises. Therefore, for example, the temperature of the exhaust air is detected by a temperature sensor 34 (see FIG. 3) installed in the middle of the path of the exhaust pipe 20 to confirm the end of the drying process.
[0028]
When the drying process ends, the operation of the hot air supply machine 33 is stopped, the on-off valve 10a of the discharge pipe 10 is opened, and the stirring mechanism 8 is operated. Thus, the fine garbage dried inside the separation / drying tank 5 is subjected to an agitation action to become powdered dry garbage, and enters the storage tank 11 positioned below the separation / drying tank 5 via the discharge pipe 10. That is, it falls into the inside of the collection bag 12 detachably attached to the storage tank 11. At this time, since the inner diameter of the discharge pipe 10 is set smaller than the outer dimension of the capturing body 7, the capturing body 7 does not fall into the storage tank 11. The same applies to the inner diameter of the discharge pipe 9. Eventually, the collection bag 12 filled with dry garbage is periodically replaced, and the collected dry garbage is effectively used as, for example, fuel or fertilizer, or incinerated.
[0029]
If stirring is not performed in the drying step, fine garbage does not disperse in the tank, resulting in a decrease in drying efficiency. Further, the fine garbage attached to the capturing body 7 cannot be sufficiently removed, and the capturing body 7 cannot be regenerated, and as a result, the capturing body 7 cannot be used for a long time. Furthermore, powdery dry garbage can be easily obtained by preventing agglomeration of fine garbage by stirring.
By using powdered dry garbage, the collection period of the collection bag 12 becomes longer, and the burden on the system administrator can be reduced. Moreover, since powdered dry garbage can be used as a fuel, a fertilizer, etc. as mentioned above, it responds to the social trend which requires recycling (recycling) of garbage.
[0030]
On the other hand, the wastewater in the storage tank 3 from which fine garbage has been removed by the solid-liquid separation step, that is, liquid wastewater, is fed to the activated sludge treatment tank 14 via the transfer pipe 13. In this case, since the lower end of the transfer pipe 13 is positioned in the vicinity of the highest region of the inclined bottom 3a, compressed air is supplied from the aeration pump 21 to the lower end of the transfer pipe 13 via the switching valve. However, the fine garbage staying in the lowest region of the bottom portion 3a does not flow into the activated sludge treatment tank 14 via the transfer pipe 13 without being mixed with solid and liquid. Thus, liquid wastewater is transferred into the treatment tank 14 and the aeration pump 21 is operated to start the activated sludge treatment.
[0031]
In the activated sludge treatment, the liquid wastewater in the treatment tank 14 is aerated and stirred together with the necessary activated sludge secured in the space 15 a by sending air into the treatment layer 14 via the air diffuser 17. As a result, the organic matter in the liquid wastewater is decomposed into carbon dioxide and water or is microbialized by the action of aerobic microorganisms in the activated sludge. After the organic matter is sufficiently decomposed, when air supply from the air diffuser 17 is stopped and aeration stirring is stopped, activated sludge is precipitated, and a supernatant layer is formed thereon. Most of the supernatant layer is discharged to the sewer or the combined treatment septic tank through the discharge pipe 18 as needed.
[0032]
On the other hand, among the activated sludge precipitated in the treatment layer 14, the activated sludge precipitated in the space 15 a is secured as necessary sludge for the next aeration and stirring, and other activated sludge (excess sludge) is discharged via the discharge pipe 18. It is fed to the storage tank 3 through the transfer pipe 16 together with the supernatant that has not been discharged. At this time, if air is fed from the aeration pump 21 to the lower end of the pipe 16 via the switching valve, the waste water containing a large amount of excess sludge is reliably fed into the storage tank 3 without being clogged by the air lift effect. Is done. In addition, the surplus sludge sent to the storage tank 3 is processed similarly to fine garbage through the solid-liquid separation process and the drying process described above.
[0033]
In an ordinary conventional treatment system, activated sludge treatment by aeration and stirring is continuously performed for 24 hours. Therefore, surplus sludge accumulates in the tank, and periodic removal work by a specialist is required. On the other hand, in the treatment system of the present embodiment, for example, after the activated sludge treatment is performed in a batch treatment form of 22 hours per day, the excess sludge is transferred from the activated sludge treatment tank to the storage tank, and the excess sludge is further refined. It can be purified like raw garbage. As a result, the excess sludge does not accumulate in the tank, and it is not necessary to periodically remove the excess sludge by a specialist. In the case of the system of this embodiment, for example, by performing activated sludge treatment for about 22 hours per day, the BOD value (biological oxygen demand) can be lowered to 200 mg / L (L: liter) or less.
[0034]
In the above-described embodiment, the aeration pump sends air through the diffusing pipe. However, in order to further improve the quality of the treated water, the air mixed with ozone is intermittently supplied, for example, about 10 minutes per hour. It is desirable to supply at a rate of In this case, the ozonizer for supplying ozone may be configured integrally with the aeration pump for supplying air, or may be configured separately from the aeration pump.
Moreover, in the above-mentioned Example, although the capture body which has a hairbrush-like form is used, the capture body which has other suitable forms, such as a scrub shape and a fiber form, for example can be used. In the capturing body of the present invention, the self-occlusion property of fine solids in the waste water discharged from the disposer is utilized. That is, in the trapping body of the present invention, a trapped portion having no water permeability and a non-blocking portion having water permeability are mixed by capturing the fine garbage, and the trapped disposable main garbage itself and the trapped disposable garbage itself. As a filter medium, solids having a small particle size are gradually captured from solids having a large particle size. By the way, when the net is used as a filter medium, the net is blocked by fine solids in the waste water from the disposer and loses water permeability.
[0035]
Therefore, it is desirable that the material of the capturing body is a material that has high capturing performance, good drying properties, and is easy to detach the captured fine solid matter so as to enable regeneration.
For this reason, it is preferable to use, for example, a resin such as polypropylene, polyethylene, Teflon, or silicon, or an appropriate metal as a material for forming the capturing body.
Moreover, in the above-mentioned Example, although the drying process is performed by the effect | action of a warm air, a tank main body can be heated with a heater type, cold air can be sent in in a tank and it can also be made to dry. In this case, for example, cold air can be fed into the tank from the aeration pump via the switching valve.
[0036]
Furthermore, in the above-described embodiment, the waste water is sucked into the pipe by sending compressed air to the lower end of the transfer pipe. However, the waste water is taken into the pipe by sending compressed air from directly under the end of the transfer pipe into the pipe. You may comprise so that it may push in. In the above-described embodiment, air is supplied to each transfer pipe using an aeration pump. However, it is also possible to prepare individual air supply pumps and supply air from each intake pump to each transfer pipe. it can. However, according to the configuration of the present embodiment, an effect of cost reduction by the combined use of the pump can be achieved.
[0037]
【The invention's effect】
As described above, in the present invention, fine garbage and surplus sludge are separated and captured from solid waste water containing a lot of fine garbage, and the separated and captured fine garbage and surplus sludge are dried to obtain a powdery dry raw waste. Collect as trash and excess sludge. The collected powdered dry garbage is effectively used as fuel or fertilizer, for example. That is, according to the present invention, it is possible to improve the storability (bulk volume, weight, odor, rot, insect generation) of fine garbage and excess sludge generated by crushing at home and effectively use them.
Further, in the present invention, liquid waste water containing almost no fine garbage is treated by the activated sludge method, and excess sludge generated by this treatment is automatically removed from the treatment tank and separated and captured in the same manner as fine garbage. Later undergoes a drying process. Thus, since only the necessary sludge remains in the activated sludge treatment tank, unlike the prior art, there is no need to remove excess sludge, and the system maintenance burden is greatly reduced.
[0038]
In particular, with the configuration in which the bottom of the storage tank is inclined, wastewater containing a large amount of fine garbage deposited in the storage tank is guided to the separation and drying tank, and liquid wastewater substantially free of fine garbage is guided to the activated sludge treatment tank. be able to.
In addition, the configuration in which the water level of the separation / drying tank is detected using the water level sensor enables good solid-liquid separation while reliably avoiding a so-called blocked state.
Furthermore, with the configuration in which the temperature of the separation drying tank is detected using a temperature sensor, the completion of the drying process can be reliably grasped, and a sufficient and quick drying process can be performed.
Moreover, the structure which supplies the air which mixed ozone intermittently through a diffuser pipe | tube can further improve a treated water quality rather than the structure which supplies only air.
Furthermore, because the waste water is sucked up from one end of the transfer pipe using the air lift effect, the mixture of the waste water and air is pumped through the transfer pipe, so that it can be reliably discharged to the outside without clogging the transfer pipe. Can lead.
[0039]
In addition, unlike the conventional system which receives all the water and mash which generate | occur | produce at the time of cooking, the mash processing system of this invention is comprised so that only the appropriate amount of water and mash used with a disposer may be received. Therefore, the entire system can be reduced in size, and as a result, it can be installed on the ground without being buried in the ground as in the conventional system. In other words, in the soot processing system of the present invention, not only the manufacturing cost is reduced by the downsizing, but also the workability is remarkably improved.
