焼酎生産とともに膨大量の蒸留残滓が発生する。2. Description of the Related Art Liquors are roughly classified into fermented liquors, distilled liquors and mixed liquors. In recent years, distilled liquors, especially shochus, have been attracting attention in view of the health trend, and their demands are increasing year by year. Shochu uses sweet potato as a raw material, as well as buckwheat, rice, millet, sorghum, etc., breeds black koji or white koji to make koji, saccharifies the koji, adds yeast, creates steamer, and steams. It is produced by mixing with the raw materials raised, fermenting it sufficiently, separating it by distillation, and producing it.
An enormous amount of distillation residue is generated with the production of shochu.

処理の解決が急務とされるに至っている。[0003] The distillation residue generated in such an enormous amount can be reused for feed, fertilizer, etc., if effective solid-liquid separation is performed due to the raw materials used and the characteristics of production, but the distillation residue is not removed. Is a BOD value of approximately 40,000 to 8
0000ppm, SS value is about 30,000-6
It has a high concentration of 0000 ppm and a high concentration and a low pH value of about 3.9 to 4.2. Particularly, in the distillation residue of so-called sweet potato shochu using sweet potato as a raw material, organic polymers such as cellulose and pectin are used. Because it contains a lot of substances, it is very difficult to dewater by a filter press or band press for solid-liquid separation because of its high viscosity, and the separated liquid separated by provisional dehydration also contains contaminants such as organic polymer substances. Therefore, the biochemical treatment for wastewater requires a large biochemical treatment tank and a long time treatment, and the sedimentation and separation of aluminum sulfate etc. Because of the necessity of using a chemical flocculant with high cohesiveness, recontamination after drainage is also a concern. However, in recent years, it has been agreed that international disposal is prohibited, as well as domestic disposal, so that efficient solid-liquid separation can be achieved, and solids can be used effectively and the separated liquid can be used efficiently and without pollution. There is an urgent need to solve wastewater treatment that can be drained.

After mixing with the distillation residue and culturing, the cultured solid secretes the contaminated solids and dehydrates it for solid-liquid separation. Alternatively, the actinomycete S-20 strain is mixed with the distillation residue and cultured for secretion. It has been proposed to decompose fibrin and high-molecular substances contaminated by enzymes to lower the viscosity and to achieve solid-liquid separation by dehydration treatment.

基準を満たす廃水処理がなし得ぬ問題も抱えている。However, flocculent yeast strain J-224 and M-11
When one strain or the like is directly used, an organic polymer substance such as fibrin or pectin is mixed in a very large amount such as distillation residue, and at least high-concentration and high-viscosity yeast is used for flocculation. since sufficient cohesive and not-cultured 108 to 10 9 or more cell concentration is unexpected is exerted, according to the culture takes a very long time, hence culture flocculation tank of very large volume by distillation residue amount generated In addition, temperature control is also required because culture is greatly influenced by temperature conditions, and furthermore, in the case of agglutination by secretions of the culture of cultures, there is a risk that dehydration may be hindered by excessive agglomeration, and thus fibrous materials, etc. Must be newly mixed in an amount of 0.5% by weight or more, which results in an increase in the amount of solid-liquid separation work. In addition, even when the actinomycete S-20 strain is used, a long culturing time, a large-volume culture coagulation tank and a temperature control are required until the degrading action of the degrading enzyme is exerted. However, there are still many problems inherent in industrially stable solid-liquid separation because the decomposition time and viscosity reduction significantly change due to fluctuations in the BOD value and the SS value. Not only is a large amount of the separated liquid subjected to solid-liquid separation by such a method generated, but also the organic polymer substances such as pectin as well as fine fibrils are contaminated at a high concentration in the separated liquid. There is also a problem that even if the liquid is subjected to general biochemical treatment, wastewater treatment that satisfies effluent standards cannot be achieved.

And re-use. The separated separated liquid contains organic macromolecular substances such as fine cellulose and pectin, and is contaminated. If the separated liquid has an extremely small BOD value or SS value, it is subjected to biochemical treatment. In addition, wastewater can be discharged by sedimentation separation. However, a special technique is required to treat the separated liquid separated by the solid-liquid separation of the distillation residue in a normal manner to meet wastewater standards. Therefore, in the present invention, the separation liquid is pressurized in the activation device and ejected and collided with high-pressure air to disperse the pollutants entrapped by the reduction of clusters of water molecules and increase the amount of dissolved oxygen to carry out biochemical treatment.

In order to mix and stir a coagulant consisting of an acidic saccharide component extracted from a culture secretion of Obasidium pullulans at a required weight ratio with respect to the distillation residue, these are immediately negatively charged and positively charged pollutants in the pollutants. In particular, coagulation floc is formed by coagulation with pectin or the like, and the coagulant consisting of chitosan in a weight ratio of 40 to 60% with respect to the glycoprotein component or acidic saccharide component is mixed and stirred, whereby the chitosan is added. Since the negatively charged pollutants in the charged pollutants are agglomerated to form flocculated flocs, respectively, the pollutants over a wide range are effectively agglomerated, and the separated liquid is separated even in the subsequent dehydration treatment. And the solid-liquid separation can be efficiently performed.

Since the polluted substances entrapped are dispersed and the amount of dissolved oxygen is increased, the microorganisms in the biochemical treatment are activated and effective biochemical treatment is performed.

Therefore, the BOD value is reduced due to the decomposition of dissolved organic macromolecules and the like by secretory enzymes accompanying the culture. The wastewater is remarkably reduced, and the SS value becomes extremely low due to precipitation and separation.
Further, since such wastewater is discharged through a heat sterilizer heated to 80 ° C. or higher, Bacillus, a gram-positive bacterium, is discharged.
Sabtilis is also digested and drained.

Is a residue obtained by removing a distillate during the production of alcoholic beverages, so-called distilled liquor. The distillation residue 1 varies depending on the raw material used, but has a BOD value of approximately 40,000 to 80,000 pp.
Approximately 30,000 to 60,000 in m and SS values
It has properties of relatively high viscosity at about 3.9 to 4.2 in ppm and PH values. The distillation residue thus formed is subjected to pH adjustment 2 in order to efficiently perform solid-liquid separation and wastewater treatment. In the case of the pH adjustment 2, it is necessary to reuse solids involved in solid-liquid separation for feed, fertilizer, and the like. The use of chemicals is naturally limited. It is also preferable from the viewpoint of exhibiting a sufficient aggregating action of a glycoprotein component or an acidic saccharide component or chitosan used as an aggregating material 3A for aggregating high-concentration pollutants in the primary treatment tank 3 prior to solid-liquid separation. It is desirable to adjust the pH value to about 6 to 6.5, and the pH value is usually adjusted by using an appropriate amount of water 2A and a trace amount of caustic soda for the distillation residue 1.

以って混合させることが望ましい。The distillation residue 1 adjusted to a required pH value flows into the primary treatment tank 3, and the coagulant 3A is removed from the distillation residue 1.
Is mixed and stirred at a weight ratio of 0.05 to 5.0%. Agglomerate 3A mixed and stirred in such a case
As the actinomyces Rhodococcus ery
tropolis or Aureob, a black yeast-like fungus
Asidium pullulans were cultured under optimal culture conditions, respectively, and glycoprotein component or acidic saccharide component 30A extracted from the culture secretion thereof, and β-poly-D-glucosamine obtained by deacetylating chitin, so-called chitosan 30B, were used. It is desired that the coagulant 3A is used, and that the glycoprotein component or acidic saccharide component 30A and the chitosan 30B are mixed and stirred with a time difference in order to enhance the cohesiveness of a wide range of pollutants. That is, the reason for this is that the pollutants mixed in the distillation residue 1 at a high concentration are various and variously mixed electrically, including negatively charged, positively charged and uncharged. Thus, the glycoprotein component or the acidic saccharide component 30A is mixed with the distillation residue 1 to be in a negatively charged state, causing the positively charged contaminants in the contaminants to be electrically aggregated, and the glycoprotein component or the acidic saccharide component being acidic. Since the saccharide component 30A also has a molecular bond such as a protein bond or a sugar chain bond, agglomeration of an uncharged pollutant immediately proceeds with mixing and stirring. On the other hand, since chitosan 30B maintains a positively charged state by being mixed with distillation residue 1, the remaining negatively charged contaminants which were previously mixed and agitated and which were agglomerated with positively charged or uncharged contaminants were successively added. By aggregating, the formation of aggregated flocs can be realized over a wide range with high aggregability and agglutination rate of pollutants. This is because the chitosan 3A is mixed with the glycoprotein component or the acidic saccharide component 30A which is mixed and stirred and coagulated in advance.
The mixing of 0B varies depending on the degree of contamination and the amount of treatment of the distillation residue 1, the mixing ratio of the glycoprotein component or the acidic saccharide component 30A, and the state of aggregation, but the mixing is generally performed with a time difference of several minutes to several hours. Is desirable.

せておくことが望まれる。The substantial mixing amount of the coagulant 3A such as the glycoprotein component, the acidic saccharide component 30A and the chitosan 30B varies depending on the BOD value and the SS value of the distillation residue 1 after the pH adjustment 2, but at least the distillation residue 1 0.05 based on the total weight of
If the mixing ratio is not more than 5% by weight, a sufficient coagulation effect cannot be exhibited, and if the mixing ratio exceeds 5% by weight, not only the coagulation effect does not show any particular improvement but also the efficiency of the dewatering treatment decreases. Up to 5.0%
Should be below the weight. Furthermore, the mixing amount of the chitosan 30B of the flocculant 3A is 4 times the mixing amount of the glycoprotein component or the acidic saccharide component 30A even from the background of many flocculation tests.
It is preferable to mix and use 0 to 60% by weight.
In addition, by changing the mixing order of the coagulant 3A to the distillation residue 1,
Even if chitosan 30B is first mixed and stirred at a required ratio to achieve aggregation, and even if the glycoprotein component or acidic saccharide component 30A is mixed and aggregated with an appropriate time difference, the aggregation efficiency and the aggregation effect are hardly affected. No difference is observed. When the coagulant 3A is mixed with the distillation residue 1, it is desirable to disperse the coagulant 3A homogeneously within a short period of time by stirring. Therefore, the coagulant 3A should be previously formed into an aqueous solution having a concentration of about 5 to 20%. Is desired.

This solid content 41A is appropriately dried and reused as a raw material such as feed or fertilizer. On the other hand, the separation liquid 41 not only generates an extremely large amount, but also contains a high concentration of organic macromolecular substances such as pectin including fine fibrous material. Except when the SS value is extremely small, general biochemical treatment and sedimentation separation make it impossible to treat wastewater that meets wastewater standards.

望ましい。In the present invention, such problems are addressed by the following two technical means. That is, one of them is to carry out the biochemical treatment of the separated liquid 41 subjected to the solid-liquid separation in the biochemical treatment tank 6 by reducing the number of water molecules in the separated liquid 41 and activating the separated liquid 41 in accordance with the increase in the amount of dissolved oxygen. In order to activate the biochemical treatment and sedimentation separation effectively, as shown in FIG. 2, the separation liquid 41 is desirably pumped by a pressure pump 5A to 1.5 to 2.0 kg / cm 2 as shown in FIG. The pressure is increased to a degree to form a pressurized separation liquid 51, and high-pressure air 5B pressurized to at least 2.0 to 3.0 kg / cm 2 is jetted from the jet nozzle 5C so that they collide with each other. Alternatively, water molecules are dissociated from each other by jetting and colliding with an appropriate collision plate 50 to reduce clusters, and at the same time, disperse pollutants in the separation liquid 41 wrapped by water molecules, thereby increasing the amount of dissolved oxygen. Let it be biological Allowed improving the processing capability to accelerate the decomposition and formation of flocs of pollutants is realized compatible wastewater treatment in wastewater standards.

At the same time, the residue is appropriately dried or fired and discarded. On the other hand, the supernatant accompanying sedimentation separation is drained to sewage or rivers as wastewater 71.In conventional general wastewater treatment, only wastewater is sterilized with a chemical disinfectant such as sodium hypochlorite and discharged.

具備した酒類蒸留残滓の処理方法といえる。According to the present invention, as described above, even distillation residue having a high concentration and a high viscosity, such as alcoholic distillation residue, especially shochu distillation residue, which is polluted with organic polymers such as cellulose and pectin at a high concentration, can be used.
In the primary treatment tank, water is added to adjust the H value, and the actinomycete Rhodococcuserythropolis is added.
Aqueous coagulant consisting of a glycoprotein component extracted from the culture secretion or an acidic saccharide component extracted from the culture secretion of the black yeast-like fungus Aureobasidium pullulans, and diluted to an appropriate concentration, is first mixed and stirred. In addition to homogenous dispersion within a short period of time, negatively charged and positively charged pollutants in pollutants are not only aggregated to form aggregated flocs, but also to protein- and sugar-chain-binding effects, and uncharged pollution. The substances also aggregate and form aggregate flocs. Then, the coagulant composed of chitosan is mixed with a time lag, so that the homogenous dispersion is similarly made within a short period of time and it is also positively charged, so that the negatively charged contaminants of the contaminants are coagulated and flocculated flocs are formed. Therefore, a wide range of pollutants are aggregated with high aggregation efficiency, and solid-liquid separation by the subsequent dehydration treatment is also efficiently performed,
The separated solids are safe and have high residual nutrients, and can be reused for feed, fertilizer, and the like. In addition, these agglomerates may be from 0.05% by weight up to 5.0% by weight of the distillation residue
If the weight ratio is not more than the ratio, sufficient coagulation and solid-liquid separation can be achieved, so that the processing cost becomes extremely low. Furthermore, the separated liquid, which is generated in a large amount by solid-liquid separation and contains a high concentration of fine pollutants, is also pressurized by passing through an activation device, and is also ejected and collided with high-pressure air. Not only are the clustered and encapsulating pollutants separated, but also the dissolved oxygen content is increased and the biochemical treatment is performed, so that the sludge bacteria are activated and a high biochemical treatment effect is achieved. Gram-positive bacteria B for biochemical treatment
Bacillus sabtilis is mixed and cultured at a cell concentration of 10 4 cells / ml or more, so that fats and oils and organic substances dissolved by a decomposing enzyme accompanying the cultivation are surely decomposed and aggregated. The COD value is remarkably reduced, and the supernatant wastewater separated from the settled sludge by the sedimentation separation can sufficiently be discharged according to the drainage standard.
In the present invention, sludge bacteria and gram-positive bacteria Ba accompanying wastewater are used.
C. sabtilis is also heat-sterilized in a heat sterilizer heated to 80 ° C. or higher and digested, so that there is no need to worry about secondary pollution associated with wastewater. I can say.
