[Solid-liquid separation process]
The obtained agglomerated separation liquid is put into a solid-liquid separation apparatus.
As an example of the solid-liquid separator, a flow in which a rotary filter, a screw press type squeezing device, and a centrifugal separator are combined is shown.
The agglomerated separation liquid is dropped into a rotary filter, and a muddy liquid containing solids (referred to as a semi-solid material) is poured into a hopper of a screw press type pressing device while draining with a filter. The liquid is squeezed out from the pores of the squeezing screen while being pushed by the screw of the screw press part (referred to as squeezed liquid). Since the solid content is contained in the squeezed liquid according to the pore size and the aggregation and separation conditions, this is returned to the rotary filter again. Solid matter is discharged from the tip of the screw and stored in a tank.
The separation liquid filtered by the filter of the rotary filter is stored in the separation liquid tank as it is, while judging the content of fine particles in the separation liquid, or further solid-liquid separation through a centrifuge and separation. The liquid is sent to the separation liquid tank, and the solid matter is sent to the tank.

Depending on the type of liquor bottle, the concentration of photosynthetic bacteria treated water, etc., and the pore size of the compression screen, the equipment cost of the equipment with the stainless filter mesh, considering the efficiency of the solid-liquid separation treatment, Set the mesh for the stainless steel filter.
As the pore diameter of the pressing screen becomes smaller, the screw press type pressing device becomes more expensive, and as the pore diameter of the pressing screen becomes larger, the price decreases, but minute particles increase toward the separated liquid and the BOD increases. The pore diameter of the pressing screen is 50 to 150 μm, preferably 80 to 130 μm. Similarly, the mesh of the stainless steel filter is # 100 to # 350, preferably # 120 to # 250.
Use of a centrifuge that removes fine particles of the separation liquid increases the efficiency of the solid-liquid separation treatment, and therefore it is preferable to provide a centrifuge.

The separated liquid subjected to the solid-liquid separation treatment contains organic acid, soluble protein, fine particles (such as fibrin), photosynthetic bacteria, and the like, and BOD is 4000 to 10000 ppm.
Organic acids, soluble proteins, and minute particles (fibrin etc.) are eutrophic substances of photosynthetic bacteria. They are propagated back to the culture tank and reused, and returned to the treated water storage tank. Reuse directly.

As shown in FIG. The improved point of the separation filter drum is shown in FIG. The improved point of the screw press type pressing device is shown in FIG.
A commercially available rotary filter is manufactured by Kurihara Tekko Co., Ltd. (Japanese Patent Laid-Open No. 10-234327 (pressing machine for producing tofu)). Using this commercially available apparatus, the agglomerate separation liquid of shochu could not be processed. It improved so that the coagulation separation liquid of shochu could be processed. In the case of tofu, the flow from the screw press type squeezing device B to the rotary filter A is passed in the order of shochu, while the flow from the rotary filter A to the screw press type squeezing device B is reversed.

  The agglomerated separation liquid is poured into the lower portion of the separation filter drum 117 through the piping from the inlet 111. A backflow prevention and roller receiver 129 is provided at the lower end of the separation filter drum 117, and a rotary filter cover 127 is provided to prevent the liquid from scattering. While the separation filter drum 117 is rotated by the rotary motor 125, the flocculated separation liquid is filtered through the separation filter. The liquid material is raised along the spiral plate 119. When it becomes a semi-solid substance that does not completely filter moisture (semi-solid outlet 115), it is poured into the semi-solid shooter 131 and stored in the semi-solid receiving tank 123. When the predetermined amount is accumulated, the semi-solid pump 513 is charged into the charging hopper 311 of the screw press type pressing device B through the semi-solid delivery pipe.

  On the other hand, the filtered liquid (separated liquid) accumulates in the separated liquid receiving tray 114, is stored in the liquid receiving tank 121 from the liquid discharge port 113, passes through the liquid delivery pipe 519 by the discharge pump 511, and stores treated water from the liquid delivery port 521. It is sent to the tank or the culture bacteria storage tank.

The semi-solid material charged in the charging hopper 311 is solid-liquid separated while being discharged and discharged from the pores of the pressing screen 351 while being compressed and moved by the screw blades 355 in the screw press 313. The screw shaft 353 is driven by a screw press motor, and the strength of the compression spring 391 that applies back pressure is squeezed and adjusted by the adjustment handle 319.
The screw shaft 353 is received by the bearing metal 379 and the nozzle port 373 is pressed by the nozzle receiving metal 377. The solid matter receives a compressive force by the screw blade 355, passes through the nozzle hole of the nozzle 371, and hits the nozzle receiving metal 377. It overcomes the strength of the compression spring 391, is discharged to the discharge portion 375, falls from the squeeze discharge port 315, and is collected in a solid material receiving box (not shown).

  The liquid (squeezed liquid) discharged from the pores of the pressing screen 351 is temporarily stored in the squeezed liquid receiving tank 523 through the squeezed liquid discharge pipe 515, and is input through the squeezed liquid discharge pipe 515 by the squeezed liquid input pump. 111 is poured into a rotary filter.

And a liquid separator. If necessary, an ultraviolet irradiation device that sterilizes bacteria other than photosynthetic bacteria in the obtained separation liquid may be added, and the separation liquid may be refluxed as a sterilized separation liquid in the culture bacteria storage tank and / or the treated water storage tank. Show.

  A commercially available two-component mixing reactor or the like may be used as the simultaneous mixing and stirring coagulation separation device. As an example, it is a device capable of mixing and stirring, having a performance of 200 to 5000 rpm, such as a seal pump and a magnet drive sealless pump. Simultaneous mixing and aggregating and separating apparatus such that a predetermined mixing ratio is obtained by a metering pump such as a gear pump, for example, a volume ratio of 75% by volume or less and 1% by volume or more of a raw solution of photosynthetic bacteria and liquor is obtained. To supply.

As the solid-liquid separator, a commercially available solid-liquid separator such as a centrifugal separator, a centrifugal dehydrator, a twin cloth dehydrator, a filter or the like can be used alone or in combination.
FIG. 13 shows a flow for the two systems of solid-liquid separation processing. In the first system, a rotary filter of separation filter meshes # 100 to # 350 and a screw press type pressing device having a pore size of 50 to 150 μm of a pressing screen are connected in series, and the obtained separated liquid is used as a mixing device. A continuous centrifugal separator that solid-liquid-separates the separated liquid that has been charged and further mixed is connected.

  In the second system, the flocculated and separated liquid that has been flocculated and separated by the simultaneous mixing and stirring flocculating / separating apparatus is solid-liquid separated using only a screw press type squeezing device with a liquid vent screw feeder, and the obtained separated liquid is put into a mixing apparatus. Further, a continuous centrifuge for solid-liquid separation treatment of the mixed separation liquid is further provided.

  As a method of further reducing the BOD of the obtained separation liquid and promoting solid-liquid separation, high-speed stirring (1000 to 5000 rpm) while aeration of the photosynthetic bacteria-treated water obtained by dilution or high-speed stirring (1000 rpm) involving air is performed. ˜5000 rpm), the separated liquid separated by the solid-liquid separation device is continuously or intermittently charged until PH reaches 6.0, preferably 6.5. To do. At this time, when the irradiation is performed while irradiating light rays mainly including wavelengths of 400 to 700 nm, the processing ability (the amount of input, the reduction of BOD, etc.) is improved. This operation is referred to as a mixing process, and the components that constitute the operation are referred to as a mixing device.

This agitated separation liquid is called a mixing liquid, and includes a smoky and floating solid and a precipitated solid. When these solid particles are observed with a microscope, they are very small, 10 to 100 μm. This mixing liquid is subjected to solid-liquid separation using a continuous centrifugal separator. The obtained separation liquid is also referred to as a mixing separation liquid. Even when this mixing separation liquid was left standing for a whole day and night and the pH was measured, the value did not change. The BOD of the separation liquid is 1000 ppm or less, whereas it is 5000 ppm or more.
The pH of the separation liquid that has been subjected to the mixing step decreases with time. When this is mixed again, the pH value is restored.

  The separated liquid including the mixed separated liquid is treated in the next step and / or sterilizes bacteria other than photosynthetic bacteria by an ultraviolet irradiation device. This has the effect of eliminating bacteria other than symbiotic bacteria. The sterilized sterilized separation liquid is refluxed to the culture bacteria treatment water tank and / or the culture bacteria storage tank, and the photosynthetic bacteria are reused.

First, the liquor lees stock solution transported from the liquor factory is stored in the liquor lees stock solution tank. At this time, the upper surface of the stock solution of the alcoholic beverage is covered with a bacterial culture solution of several centimeters of photosynthetic bacteria. By doing so, the odor will not be emitted for more than two weeks. Very good for working environment.
According to the predetermined treatment amount, the liquor cake stock solution is transported from the metering pump, the cultured Sato bacteria treated water diluted to a predetermined concentration is transported from the metering pump, and the liquor cake stock solution is mixed at a mixing ratio of 75 vol% or less and 1 vol% or more. Mix together in a mixer and stir. Aggregation separation is completed within 10 minutes.

In the liquor manufacturing factory, when the present invention is carried out, the temperature of the liquor cake is 50 to 95 ° C. because of the temperature rise caused by fermentation and the temperature rise caused by distillation. When mixing and agitating simultaneously, it is preferable to set the mixing ratio so as to be in the temperature range of 20 to 35 ° C. where the activity of photosynthetic bacteria is high.
Outside the liquor manufacturing factory, when the present invention is carried out, it is stored in a liquor lees storage tank, so if the liquor lees are measured at a temperature of 50 degrees C or less, the culture is diluted at a predetermined mixing ratio. It is good to mix and agitate with Sato-treated water.
When simultaneous mixing and stirring deviates from the temperature range of 20 to 35 ° C. where the activity of photosynthetic bacteria is high, the aggregation and separation are completed within 10 minutes after the temperature range is reached.

The obtained agglomerated separation liquid is put into a solid-liquid separation apparatus.
As an example of the solid-liquid separator, a flow in which a rotary filter, a screw press type squeezing device, and a continuous centrifugal separator are combined is shown.
The agglomerated separation liquid is dropped into a rotary filter, and a muddy liquid containing solids (referred to as a semi-solid material) is poured into a hopper of a screw press type pressing device while draining with a filter. The liquid is squeezed out from the pores of the squeezing screen while being pushed by the screw of the screw press part (referred to as squeezed liquid). Since the solid content is contained in the squeezed liquid according to the pore size and the aggregation and separation conditions, this is returned to the rotary filter again. Solid matter is discharged from the tip of the screw and stored in a tank.
The separated liquid filtered by the filter of the rotary filter is stored in the separated liquid tank as it is, while judging the content of the minute particles in the separated liquid, or further solid-liquid separated through a continuous centrifugal separator, The separation liquid is sent to the separation liquid tank, and the solid matter is sent to the tank.

Depending on the type of liquor bottle, the concentration of photosynthetic bacteria treated water, etc., and the pore size of the compression screen, the equipment cost of the equipment with the stainless filter mesh, considering the efficiency of the solid-liquid separation treatment, Set the mesh for the stainless steel filter.
As the pore diameter of the pressing screen becomes smaller, the screw press type pressing device becomes more expensive, and as the pore diameter of the pressing screen becomes larger, the price decreases, but minute particles increase toward the separated liquid and the BOD increases. The pore diameter of the pressing screen is 50 to 150 μm, preferably 80 to 130 μm. Similarly, the mesh of the stainless steel filter is # 100 to # 350, preferably # 120 to # 250.
Use of a continuous centrifugal separator that removes minute particles of the separation liquid increases the efficiency of the solid-liquid separation treatment, and therefore it is preferable to provide them continuously.

The separated liquid subjected to the solid-liquid separation treatment contains organic acid, soluble protein, fine particles (such as fibrin), photosynthetic bacteria, and the like, and BOD is 4000 to 10000 ppm.
Organic acids, soluble proteins, and minute particles (fibrin etc.) are eutrophic substances of photosynthetic bacteria. They are propagated back to the culture tank and reused, and returned to the treated water storage tank. Reuse directly.

Add 500 mL of the shochu shochu stock solution to this 2 L PET bottle and shake for 5 minutes. Let stand for 5 minutes, then pour into a 120 mesh cloth bag. It can be easily squeezed by hand. While squeezing by hand, it was filtered and finished squeezing when the solid became clay-like. The filtrate was packed into a 2 L plastic bottle as a separated liquid and weighed. The pH of this separated solution was measured with a pH meter. It was allowed to stand for 12 hours, and the height of the precipitate on which fine particles settled was measured. 500 mL of the supernatant was collected as a sample for measuring BOD.
On the other hand, cloth bags that were quickly squeezed were weighed. Then, it put into the dryer and dried and weighed.
The results are shown in Table 3.

It cannot be squeezed unless the force of squeezing by hand is increased. Finish when muddy solids ooze from the stitches. The separated solid did not become clay-like and was a paste-like. Although it was easier to squeeze than the stock solution of shochu, it was found that it was difficult to agglomerate and separate.
Table 4 shows the measurement results.

The same procedure as in Example 4 was performed except that 50 mL or 100 mL of cultured Bacillus was mixed with 100 mL of cultured Sato bacteria. Table 4 shows the measurement results. Both were found to aggregate and separate in a short time. Since the value of the separated liquid ratio is small, it can be seen that there is also an effect of Bacillus bacteria.

200 L of barley shochu stock solution is obtained from SP. 100 g was collected from this and dried in a dryer 90-110 degrees. The weight was measured immediately and a result of 13.0 g was obtained. The solid content of the shochu is 13 wt%.

Obtain 200L of the stock solution of shochu shochu from OG shochu. 100 g was collected from this and dried in a dryer 90-110 degrees. The weight was immediately measured using a 250 g scale, and a result of 3.35 g was obtained. The solid content of the shochu is 3.35 wt%.
150 L of water was added to 1.5 L of cultured Sato fungus in a 1 ton tank and stirred for 5 minutes. To this was added 100 L of a shochu stock solution with a pump at a flow rate of 80 L / min. The mixture was stirred for 30 minutes using a submersible pump at a flow rate of 80 L / min. Then, it put into the rotary filter A at a flow rate of 8.5 L / min.
The filtration conditions of the rotary filter are a rotation speed of 42 rpm, a 120 mesh stainless steel filter, a rotation axis inclination θ = 4.2, a height of the spiral cutting plate 119 of 50 mm, and a spiral pitch of 150 mm. Drove for 30 minutes.
The separation filter drum 117 is rotated while filtering the flocculated separation liquid with a separation filter. The liquid material is raised along the spiral plate 119. The semi-solid material in a muddy state that does not completely filter moisture is stored in the semi-solid material receiving tank 123. Ten minutes later, the semi-solid was charged into the charging hopper 311 of the screw press type pressing device B with a semi-solid pump. Drove for 20 minutes. The operating conditions of the screw press type pressing device are a screw rotation speed of 90 rpm and a pore diameter of the pressing screen 351 of 120 μm.

The solid was stored in a solid receiver. Immediately, the solid was weighed to obtain 3.386 Kg. This was dried in a dryer 90 to 110 degrees. The dried solid was 1.185 kg.
The squeezed liquid separated into solid and liquid was stored in the squeezed liquid receiving tank 523. The squeezed liquid charging pump 525 was added again to the rotary filter A.
The pH of the separation liquid was 4.92. The precipitation height after 12 hours was 11 mm (87 mL) with respect to the height of the separation liquid of 275 mm (1800 mL).
The processing capacity of this solid-liquid separation system is estimated to be 7 tons / day of shochu stock solution.

[Comparative Example 3]
40 L of water was mixed with 40 L of culture-sterilized eco-bacteria treated water (10 4 / ml), and 40 L of shochu stock solution manufactured by OG was added thereto and stirred for 10 minutes to prepare an agglomerated separation liquid.
This agglomerated separation liquid was put into a rotary press integrated screw press type pressing device for tofu that was installed at Kurihara Tekko Co., Ltd. As in the case of tofu, after squeezing with a screw press type squeezing device, it was filtered with a rotary filter.
The operating conditions are a screw press type squeezing device with a screw rotation speed of 90 rpm and a compression screen pore size of 200 μm, and a rotary filter as a separation filter drum length of 800 mm, a drum diameter of 350 mm, stainless steel separation filter # 100, a rotation speed of 14 rpm. It is.
The fiber material was discharged while entangled as a solid content, and after a while, smoke was generated from the discharge part. The recovered liquid was not different from the aggregated separation liquid at the time of charging. When the collected liquid was filtered with a 120 mesh cloth bag type filter, about 3 kg of solid matter could be recovered. From this fact, although it was agglomerated and separated, when the hole diameter of the screw press was 200 μm It was found that it was too large to collect solids other than fibers.

80 L of water was mixed with 500 mL of cultured Sato fungus (10 8 cells / L), and 40 L of an OG shochu stock solution was added thereto, followed by stirring for 10 minutes to prepare an agglomerated separation solution.
Only the screw press type pressing device installed in Kurihara Tekko Co., Ltd. was used, the diameter of the pores of the pressing screen was 120 μm, and the screw was squeezed at 90 rpm.
Solids other than the fiber could also be collected, and the collected liquid was filtered through a 120-mesh cloth bag filter. Solid-liquid separation was possible. However, the processing capacity was greatly reduced and other problems remained.

The same aggregating / separating liquid as in Example 10 was used.
Before squeezing with a screw press type squeezing device, it was set as the procedure of carrying out rough filtration with a rotary filter. The separation filter mesh of the rotary filter was # 120. The measurement was performed at a spiral plate height of 30 mm, a drum diameter of 350 mm, a length of 800 mm, and a rotation speed of 14 rpm. The pressing screen of the screw press type pressing device was squeezed at a pore size of 120 μm and a screw rotation speed of 90 rpm.
Solid-liquid separation was successful, but at the end, the discharge pulsated and clogged.
Some problems were also found in the rotary filter. Experimented with improvements. This is Example 9.

The improvement inside the apparatus is as follows for the rotary filter.
1. The radius D1 of the separation filter drum 114 was increased to 200 mm.
2. The length L of the separation filter drum 114 was increased to 1000 mm.
3. The center line of the rotation axis of the separation filter drum 114 was tilted 4.2 degrees upward from the horizontal.
4). The filter of the separation filter drum 114 was a stainless steel filter, and the mesh count was increased by # 120.
5. The height (D1-D2) of the spiral plate 119 was increased to 50 mm.
6). The rotational speed was increased to 42 rpm.

The improvements regarding the screw press type pressing device are as follows.
1. The nozzle shape was changed from parallel to a triangular pyramid, and the nozzle opening was blunted to make it larger.
2. The fluid was retained in the retention part.
3. The range of compression force of the compression spring has been expanded.

2-u. 2 lots of 2-l to 2-s and shochu are put into a centrifuge, and a solid-liquid separation operation is performed at a rotational speed of 3000 rpm for 1 minute.
2-v. 2 lots of 2-l to 2-s and shochu are put into a centrifuge, and a solid-liquid separation operation is performed at a rotational speed of 3000 rpm for 3 minutes.

2-x. 2 lots of 2-l to 2-s and shochu are put in a centrifuge, and a solid-liquid separation operation is performed at a rotational speed of 3000 rpm for 10 minutes.

  The precipitation height in the PET bottle at the time when 12 hours had passed after shaking and stirring was measured for 1-b to 1-p. The results are shown in Table 6. The pH of the supernatant in the PET bottle at this time was also measured, and the results are shown in Table 6.

100g was collected in an aluminum foil case (manufactured by Sumikara Aluminum Foil Co., Ltd.) in which a stock solution of sake liquor was weighed, and the plate heater was set at 100 ° C and placed on a plate and dried. The weight was measured to be 18.07 g. Since the tare was 13.05 g, it was found that the solid content in the liquor cake stock was 5.02 g and 5.02 wt%.
The amount of solid matter was measured for 1-b, d, f, h, and k by the same measurement method. The results are shown in Table 7. All were about 5 wt%.

The height of the solid substance of the capsule separated into solid and liquid by a centrifuge was measured, and the state was observed.
The results are shown in Table 8. The alcoholic liquor stock solution is 44-50 mm high, and the solids settle at the bottom of the capsule, but are semi-solid and soar even with slight vibration. The supernatant liquid was also slightly cloudy.
As for 2-b, d, f, h, and k, the solid content adhered to the bottom of the capsule after centrifugation, and even if the liquid content was spilled, the solid content remained in the bottom of the capsule.
2-l, m, n, o, p, source, source / 4, after centrifugation, the solid content settles on the bottom of the capsule but is semi-solid and soars even with slight vibration.
From these results, it can be seen that the liquor liquor stock solution is easily separated when diluted with water, and aggregates and separates when microorganisms such as photosynthetic bacteria are included. In addition, it can be seen that the agglomeration and separation can be easily performed with a short shaking and stirring for 3 minutes. It can be seen that even when the number of cells is 10 −3 cells / mg or less, aggregation and separation in a short time occur.
When the number of cells was 10 to the -1th power / mg order (1-o, p), there was only a slight difference from the 4-fold dilution of water, and it seemed that the solids were slightly slimy.
It was found that even when the photosynthetic bacteria-treated water obtained by dilution (10 2 to 10 12 / mL) was used, it was aggregated and separated in a short time.

  The residue of the separated liquid was stirred, 600 mL was collected, and the BOD of the liquid obtained by solid-liquid separation using a centrifuge was measured. It was 4500-4900 ppm. It was found that the centrifuge removed minute particles and lowered the BOD.

An experiment similar to that of Example 12 was performed except that alkali-resistant and alkali-resistant photosynthetic bacteria were used instead of the cultured Sato bacteria.
Any concentration of photosynthetic bacteria (red non-sulfur bacteria, alkali-resistant photosynthetic bacteria having bacterial chlorophyll a and neurosporene (Rhodopseudomos), alkali-resistant chlorophyll a and β-carotene (Synochococcus)) It was found that the flocculation and separation occurred in a short time.

Obtain 200L of the stock solution of shochu shochu from OG shochu. 100 g was collected from this and dried in a dryer 90-110 degrees. The weight was immediately measured using a 250 g scale, and results of 3.90 g and 4.05 g were obtained. The solid content of the shochu is 3.98 wt%.
FIG. 14 shows an experimental diagram of shochu coagulation separation and solid-liquid separation by simultaneous mixing and stirring. Connect the metering pump P1 to the stock solution tank of shochu, the metering pump P2 to the culture Sato-treated water tank, connect the mixing pipe that can be stirred by the water wheel immediately after joining the pipes, and connect the outlet to the rotating drum of the rotary filter Plug in. A residence pipe was provided at the outlet, and this residence time was set within 2 minutes. Since the water wheel blades were rotated by the water pressure and stirred, the rotation speed was 200 rpm or less. The mixing ratio of 50-fold diluted cultured Sato-treated water and shochu was set to 3: 1.

The rotary filter was charged at a flow rate of 8.5 L / min.
The filtration conditions of the rotary filter are a combination of a rotational speed of 42 rpm, a combination of 150 and a 120-mesh stainless steel filter, a tilt of the rotation axis θ = 4.2, a height of the spiral cutting plate 119 of 50 mm, and a spiral pitch of 150 mm. The operation was continued until the stock solution of shochu disappeared.
The separation filter drum is rotated while the flocculated separation liquid is filtered through the separation filter. The liquid is raised along the spiral plate. Within 2 minutes, store the semi-solid in a semi-solid state that does not completely filter moisture in the semi-solid receiving tank. Ten minutes later, the semi-solid was charged into a charging hopper of a screw press type pressing device with a semi-solid pump. Driving intermittently for 20 minutes. The operating conditions of the screw press type pressing device are a screw rotation speed of 90 rpm and a pore diameter of the pressing screen of 120 μm.

The solid was stored in a solid receiver. Immediately, the solid was weighed to give 3.172 Kg. Each 200 g of this sample was collected and dried with a dryer at 90 to 110 degrees. The dried solids were 54.72g and 55.18g. The solid content was 27.36 wt% and 27.59 wt%, respectively. The discharged solid from the screw press type pressing device was calculated to be 0.871 Kg. The residual solid weight collected from the rotary filter tank and the screw press type crusher cylinder was 8.669 kg. 300 g of this sample was sampled and dried, and the solid weight was measured. The solid content was 3.14 wt% and 2.92 wt%, respectively. The solid matter was calculated to be 0.263 kg.
The squeezed liquid separated into solid and liquid was stored in a squeezed liquid receiving tank. The rotary filter A was recharged with a squeeze liquid charging pump.
The pH of the separation liquid was 4.94. The precipitation height after 12 hours was 23 mm with respect to the separation liquid height of 260 mm. The BOD of the separated liquid was 3800 ppm.
By co-mixing and stirring, it was possible to agglomerate and separate within 5 minutes and then to separate into solid and liquid within a few minutes. Table 9 shows the results of the above examination.

The separation liquid obtained in Example 13 was processed by a mixing process.
[Test 1]
25 L of 50-fold diluted cultured Sato-treated water was placed in a 500 L plastic tank and stirred using a stirrer with a rotational speed of 3000 rpm while entraining air. To this, 688 g of the separated liquid was added at an interval of 10 minutes, and the water temperature and pH were measured. The results are shown in Table 5. The change in pH treatment time is shown in FIG. The pH recovered in 10 minutes, and even after stirring for 80 minutes and adding 5.5 L of the separation liquid, there was little decrease in pH. The BOD of this mixing separation liquid was 650 ppm.
This mixing separation liquid was subjected to solid-liquid separation using a centrifuge. FIG. 16 shows a state in a capsule and a state after centrifugation. The mixed separation liquid that has been mixed has a lower turbidity than the separation liquid, and is considerably transparent after centrifugation. The separation liquid has fine particles floating, has a high turbidity, and has a light brown color even after centrifugation. It can be seen that the amount of separated solids is also greatly reduced through the mixing process. The BOD of the centrifuged supernatant was 610 ppm.
After adding 5.5 L of the separated liquid, stirring was continued at 3000 rpm for 180 minutes. BOD was 620 ppm.

[Test 2]
The experiment was performed in the same manner as in Example 14 except that the rotation speed was 2000 rpm. The results are shown in Table 10, and the change in pH treatment time is shown in FIG.

[Test 3]
The same procedure as in Example 15 was repeated except that 688 g of the separation liquid was continuously added for 10 minutes, the temperature and pH were measured, and this was subsequently repeated. The results are shown in Table 11, and the change in pH treatment time is shown in FIG.
[Test 4]
Further, a similar experiment was performed while irradiating with a halogen lamp.
The results are shown in Table 11, and the change in pH treatment time is shown in FIG.

[Test 5]
The number of revolutions was set to 2000 rpm, and 5.5 L of the separation liquid was added all at once, and the temperature and pH were measured every 10 minutes. The results are shown in Table 11, and the change in pH treatment time is shown in FIG.

[Comparative Example 4]
In 1700 cc of water, 34 cc of cultured Sato bacteria was used as a base (diluted 50-fold). The pH was measured every 5 minutes.
4 cc of shochu was dripped into the 50-fold diluted cultured Sato-treated water every 5 minutes and stirred, and the pH was measured every 5 minutes. The pH of the cultured Sato bacterium at this time was 7.90, and the pH of the 50-fold diluted cultured Sato bacterium treated water was 7.29.
The results are shown in Table 12, and changes in pH treatment time are shown in FIG. It can be seen that if the mixing process is not performed, the pH will continue to drop, and that recovery will take a long time if it is added all at once.

FIG. 13 shows a schematic diagram of an experiment using a Sealex pump (Sealless Pump SL-40N manufactured by Elepon Chemical Industries Co., Ltd.) as a simultaneous mixing and stirring device.
A 40L tank and a regulating valve were attached for safety. It took less than 1 minute to feed the rotary filter through the metering pump, tank, sealex pump, and adjusting valve. 500 kg of shochu was carried in and stored in the shochu storage tank. A 50-fold diluted cultured Sato-treated water was prepared and stored in a cultured Sato-treated water tank. The mixing ratio of 50-fold diluted cultured Sato-treated water and shochu was set to 5: 1 with a metering pump. The number of revolutions of the Sealex pump was set to 1000, 2000, 3000, 3490, 4000, and 5000 rpm for aggregation separation.
All of them were coagulated and separated, and solid-liquid separation was possible with a rotary filter.

An example of the decomposition treatment tank of the alcoholic beverage decomposition processing system of the present invention is shown in FIG. 14 as a front view and FIG. 15 as a side view. It is comprised from the decomposition processing tank which has a bubble collection tank and a rotating drum. The aeration device seems to lead to accelerated decomposition. Catalytically decomposed activated carbon is effective as a place to live photosynthetic bacteria. What is necessary is just to comprise these as needed.
In the front view, the water flow (51) sent out from the stirrer (11) comes into contact with the underwater catalytic cracked activated carbon (15) and flows upward like the water flow (53). The air mixed in the water becomes bubbles and floats on the water surface, and enters the bubble recovery tank (19) into the tank (57) having a low water level with the flow of the water flow (55). The water is sucked up from the pump suction port (35) to the pump (33), fed into the water supply pipe (37), and discharged from the water discharge port (39) in the drum into the rotary drum (13). The liquid passes through the separation filter drum (71), flows to the catalytic cracking activated carbon (17), and the solids collected together with the air bubbles are sent out through the drum by the spiral plate (73), and the solid discharge port ( 75). The liquid circulates back through the catalytic cracking activated carbon (17) from the drum outlet (77) into the water tank.

50-fold diluted cultured Sato-treated water and liquor mixing liquid (BOD = 740 ppm and 680 ppm) were inserted into a 20 L decomposition treatment tank at a mixing ratio of 3: 1 and decomposed and purified.
When processed with aeration, the BOD = 740 ppm mixing separation decreased to 24 ppm after 24 H and to 89 ppm after 48 H. The change of pH at that time is shown in Table 13, and the graph of the change is shown in FIG. From the fact that the pH value is increased after the treatment, it is understood that the substance is decomposed and purified.

When aeration was not performed, the BOD = 680 ppm mixing separation solution decreased to 24 ppm after BH to 110 ppm and after 40 H to 26 ppm. The change in pH at that time is shown in Table 14.
It can be seen that it can be processed to a discharge allowable value of 160 ppm within 24 hours.
