理方法に関する。DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention can generate fuel gas having a large calorie at a high rate by using blood juice or boiled juice discharged in a fish meal manufacturing process or other fishery processing processes as a raw material. It relates to a very useful methane fermentation treatment method.

らは一般に次のように処理されている。2. Description of the Related Art Conventional Techniques and Their Problems Conventionally, fresh fish such as sardines and many fish iliac bones recovered from fresh fish merchants, canners and other processors have been used as feeds through a fish meal production process. In this fish meal production process, a large amount of blood juice and boiled juice is discharged, and these are generally treated as follows.

方、煮汁の場合は、上記の生物分解処理を行って放流す

用を図っている。That is, in the case of blood juice, it is diluted with water, subjected to biodegradation treatment, and discharged as purified wastewater having a water quality regulation value or less. On the other hand, in the case of boiling juice, the above-mentioned biodegradation treatment is carried out and discharged, or it is heated and concentrated to reuse it as a fish soluble.

ているのが実情である。However, when blood or boiled juice is treated by such a method, there are the following kinds of problems. Taking the broth as an example, the properties of the broth are generally about 10% solids (wt%, the same applies hereinafter), about 9% organic matter,
D is about 60000mg /, COD is about 11000mg /, total nitrogen is about 1200
0 mg /, the total carbon is about 48000 mg /, and the carbon ratio (C / N ratio) is as low as 4; On the other hand, when heat-concentrating into a fish-solvable, there is a problem that the amount of water in the broth is large and a large amount of heat energy is required, so that the energy cost is high. In recent years, which has been sluggish, it has become impossible to make a profit or loss at all. Still, when fish meal is produced using fresh fish as a raw material, the obtained fish soluble can be used for the production of whole meal by inputting it into the drying process during the production of fish meal, but it is still good, When fish meal is manufactured using bone as a raw material, the resulting fish solvable has problems in quality, such as oxidation of oil, and cannot be used for the production of whole meal. It is the fact that it is hurt.

いといった問題もある。Under such circumstances, attempts have been made to recover and use as an energy resource by subjecting boiled juice and blood juice to methane fermentation. However,
As mentioned above, broth and the like have a low carbon content and contain a large amount of sulfur-containing amino acids, etc., so that ordinary mesophilic fermentation using a mechanically stirred single-tank methane fermentation tank adversely affects methane fermentation bacteria. There is a problem that the concentration of ammonia and hydrogen sulfide increases with time, making normal methane fermentation difficult, and the amount of gas generated is significantly reduced. And BO of digestive juice
Since the D value and COD value are high, there is also a problem that the post-treatment of the digestive juice is not easy.

要になってきた。Thus, the present inventors have conceived a system for treating two birds per stone, which improves the processing efficiency of methane fermentation by separating and recovering colloidal proteins from boiled juice and blood juice, and effectively utilizes the separated and recovered proteins as feed. , Advanced the research. However, although the effect of improving methane fermentation is recognized to some extent only by separating colloidal proteins from broth, etc., ammonium nitrate and hydrogen sulfide are considerably generated from the dissolved nitrogen-containing compounds and sulfur-containing compounds. It is difficult to perform methane fermentation, and it has become necessary to drastically improve the methane fermentation process itself.

When fermenting blood juice or broth in a methane fermentation tank,
The gist is that the generated gas is circulated to perform gas agitation of the methane fermentation liquid, and that ammonia and hydrogen sulfide are removed during the gas circulation.

Is circulated in the stirring gas and removed in the course of the circulation, so that the concentration of harmful ammonia and hydrogen sulfide in the methane fermentation tank is greatly reduced.
Therefore, since methane fermentation bacteria are active and normal methane fermentation is continuously performed, high calorific gas comes to be generated stably at a high rate, and the BO value and COD value of digestive juice are also increased. Extremely small.

であり、固形物中の約80％が粗蛋白質である。FIG. 1 is a flowchart of a methane fermentation process according to one embodiment of the present invention, and FIG. 2 is a schematic configuration diagram of a methane fermentation tank with a gas circulation device used in the present invention. As shown in FIG. According to the methane fermentation treatment method of the present invention, first, blood juice or broth as a raw material is diluted about twice with water. Blood juice used as a raw material is a liquid discharged from storage pits and transport pits, and contains exudate from blood, blood, internal organs, meat pieces, and the like.Boiled juice is a liquid discharged from a cooker and is a fish liquid. Extracts, blood, internal organs, juice components (proteins), and bone juice components. The properties of the broth are as described above, and about 80% of the solid is crude protein.

釈して直接凝集物を分離してもよい。When dilution of the raw material such as broth is completed, about 1% by volume of acetic acid is added to the diluted solution. When acetic acid is added in this manner, the colloidal protein in the diluent is in a state of being substantially at the isoelectric point, and thus rapidly aggregates. In this embodiment, acetic acid, which is preferable as a flavoring agent, is added to coagulate proteins. However, other than this, organic acids such as formic acid or inorganic acids may be added to coagulate proteins. However, if the raw material has a low concentration, the aggregate may be directly separated by diluting it several times.

飼料（粗蛋白質が約80％）が得られる。Once the protein has aggregated, the aggregate is then centrifuged through a high speed centrifuge. The aggregate separated and recovered in this way contains about 83% of water, and is predried to reduce the water to about 50%.
By doing so, it can be processed into a pellet shape. And
When this is dried, most of the attached acetic acid volatilizes, and a small amount of acetic acid remains as a feed flavoring, and a valuable high protein feed (about 80% crude protein) is obtained.

る。When deproteinization is performed as described above, nitrogen-containing compounds and sulfur-containing compounds that are harmful to methane fermentation are removed by about 15%, and their contents are reduced from about 6500 mg / to about 5500 mg /. Although the improvement effect can be recognized to some extent, as described above, since the raw material liquid still contains a considerable amount of soluble proteins, sulfur-containing amino acids, and the like, the usual mechanical stirring type single tank methane is used. Even if it is put in a fermentation tank and subjected to medium temperature fermentation, it is difficult to perform methane fermentation normally.

てガス撹拌を行いながら循環するようになっている。Therefore, in the present invention, the solution subjected to the deproteinization treatment is introduced into the solubilization tank and subjected to acid fermentation for about 5 days, and then introduced into the methane fermentation tank equipped with a gas circulation device as shown in FIG. Alternatively, a methane fermentation treatment is performed by a high-temperature fermentation method. A gas circulation device 2 attached to the methane fermentation tank 1 includes a sulfuric acid tank 22 and an iron oxide filling tank 23 in the middle of a circulation pipe 21 as shown in the figure.
Are provided in series, and both ends of a circulation pipe 21 are connected to the top and bottom of the methane fermentation tank 1, respectively. Therefore, the gas generated in the methane fermentation tank 1 contacts the sulfuric acid 3 in the sulfuric acid tank 22 through the circulation pipe 21 from the upper part, and then contacts the iron oxide 4 in the iron oxide filling tank 23 to form methane. Returning to the bottom of the fermenter 1, the methane fermentation liquid 5 is circulated while bubbling and stirring the gas.

ようになる。When the methane fermentation liquid 5 is stirred with the gas circulating in this way, harmful ammonia and hydrogen sulfide generated in the methane fermentation liquid 5 are retained in the stirring gas, and the circulating pipe
Circulates through 21 and, on the way, comes in contact with sulfuric acid 3 in sulfuric acid tank 22 to remove ammonia as ammonium sulfate,
Further, the hydrogen sulfide is removed as iron sulfide by contacting the iron oxide 4 in the iron oxide filling tank 23. Therefore, when this gas circulation is repeated, the concentration of ammonia and hydrogen sulfide is greatly reduced, and the amount of ammonia in the methane fermentation liquor 5 is about 2700 mg /
And hydrogen sulfide in the circulating gas drops to about 78 ppm. Therefore, since methane fermentation bacteria are active and normal methane fermentation is continuously performed, high calorific gas is consumed.
It is generated stably at a high rate of 0.63 / g (about 63% decomposition rate).

槽を経てメタン醗酵槽に戻すようにしてもよい。In this embodiment, the sulfuric acid tank 22 and the iron oxide filling tank 23 are provided in the middle of the circulation pipe 21 as described above as the gas circulation device 2.
Ammonia and hydrogen sulfide are removed separately, but instead of this, a gas circulation device equipped with only one tank filled with iron sulfate is used to simultaneously remove ammonia and hydrogen sulfide. It may be removed. In some cases, the gas from which ammonia and hydrogen sulfide have been removed may not be directly returned to the methane fermentation tank, but may be partially or entirely returned to the methane fermentation tank via the solubilization tank.
