廃液をメタン醗酵処理するような場合に好適に採用され
るメタン醗酵方法に関する。Description: TECHNICAL FIELD The present invention relates to a methane fermentation method which is suitably employed when methane fermentation treatment of alcoholic waste liquid such as shochu, liquor, beer, wine and the like.

が必要となり、経済的に採算がとれない。Since the waste liquid obtained by fermenting alcohol with yeasts, such as the distillation waste liquid of barley shochu, contains about 8% of organic substances, the concentration of organic substances is too high to be treated by the activated pre-mud method, and the treatment is satisfactory. It is difficult. However, concentrated by heating,
Since the concentration of organic matter is too low for solidification, a large amount of fuel is required, and it is not economically viable.

わらず、第４図のグラフに示すようにメタン醗酵が充分
に行われないという問題に直面した。Therefore, the present inventors have invented the idea of performing a methane fermentation treatment of such a distillation waste liquid or the like to generate a combustible gas and use it as an energy source, and to treat a digested liquid having a reduced organic substance concentration with activated sludge and discharge it. did. However, when the distillation waste liquid of barley shochu is actually subjected to methane fermentation treatment, methane fermentation is sufficiently performed as shown in the graph of FIG. 4 even though the distillation waste liquid does not contain inhibitors such as sulfur-containing compounds. Faced the problem of not being done.

にメタン醗酵が困難な状態になることが判る。That is, the graph of FIG. 4 shows that the organic waste volume load was 2.72 kg VS after solubilizing the distilled waste liquid of barley shochu for 5 days in advance.
/ m 3 · day, digestion time set to 20 days, methane fermentation treatment by medium temperature fermentation at 40 ° C, and the change over time in pH and gasification rate (gas generation amount) of the treated liquid So, if you look at this, from the start of methane fermentation until about 16 days, the treatment solution is maintained at around pH 7.5, the gasification rate is also 0.5 / g
Although it is maintained at a relatively high value of around VS, it can be seen from around 16 days that the pH and gasification rate of the treatment liquid rapidly decrease, and methane fermentation becomes substantially difficult.

知見を得るに至った。The present inventors have conducted intensive studies to find out the cause, and the main cause is that organic substances contained in the distillation effluent of barley shochu are substrates that have already been subjected to alcohol fermentation by yeasts, so that methane bacteria and the like are present. It has been found that amino acids and other nutrients and minerals necessary for the growth of anaerobic microorganisms are insufficient, or that nutritional balance is out of place.

It also contains a lot of various minerals. Therefore, by blending this in the waste liquid in an appropriate amount, if nutrients and various minerals are replenished and nutrition balance is achieved, methane bacteria will proliferate and actively decompose organic matter in the waste liquid. The methane fermentation treatment can be performed with a high gasification rate.
以下、図面を参照しながら本発明の実施例を詳述す

る。FIG. 1 is a flow chart for explaining an embodiment of the methane fermentation method of the present invention. In this embodiment, a barley shochu waste liquid (distilled waste liquid) is used as a waste liquid to be treated, and animal and plant substances to be mixed with the waste liquid. As a sticky water or a fish solvable which is an animal protein solution.

が消費されて少なく、またミネラル分も僅かである。The barley shochu solution is usually prepared with an organic matter (VS) concentration of 70,000-1
Since it is a waste liquid after fermentation with alcohol by yeast cells at about 00000 mg / liter, nutrients such as amino acids and phosphoric acid are consumed little and the mineral content is also small.

めて多いものである。On the other hand, stick water is generated in the fish processing step of fisheries factories, and usually has a VS concentration of 30,000 to 40,000.
Although relatively small, on the order of mg / mg, it is rich in nutrients such as free amino acids, low molecular weight peptides, phosphoric acid, and various minerals necessary for the growth of methane bacteria and other anaerobic microorganisms. Fish Soluble is obtained by heating and concentrating stick water, and although the VS concentration varies greatly depending on the degree of concentration, the content of nutrients and minerals is extremely high.

(Weight%, the same applies hereinafter). If it is less than 6%, it is difficult to say that nutrients and minerals are sufficiently replenished. Conversely, if it exceeds 7%, the amount of hydrogen sulfide, ammonia, etc. generated during methane fermentation increases, and the tendency to inhibit the activity of methane bacteria becomes stronger.

Above is not very desirable for methane fermentation,
The VS concentration of the whole mixture is 100000 mg / or less, preferably 900
It is better to adjust it to be around 000mg /. Therefore,
When using Fish Soluble, it is desirable to mix and dilute it so that it has the same VS concentration as the stick water.

てメタン醗酵処理が進行する。The barley shochu waste liquid containing the stick water or fish soluble as described above is subjected to acid fermentation in a solubilization tank for about 5 days, and then introduced into a methane fermentation tank having an adiabatic structure.
Perform methane fermentation by medium temperature fermentation at 35-40 ° C. In this case, if the organic substance volume load is too large, it is difficult to perform the methane fermentation treatment sufficiently.
It is desirable to set it to about 3 kgVS / m 3 · day, and it is desirable to determine the volume of the methane fermentation tank and the amount of waste liquid introduced so that the digestion time is about 30 days at this load. When methane fermentation is carried out under such conditions, the waste liquid contains nutrients and various minerals such as free amino acids, low-molecular peptides, and phosphoric acid replenished by the addition of stick water or fish solvable. The methane bacteria multiply and actively decompose anaerobic organic substances in the waste liquid, and the waste liquid maintains a pH of about 7.5 to 8.0, which is suitable for methane bacteria. The methane fermentation process proceeds with the gasification rate.

廃液のガス撹拌に用いられる。Digested gas generated in the methane fermentation tank is dehumidified and desulfurized through a dehumidifier and desulfurizer, and then collected in a collection tank.A part of the digested gas is returned to the methane fermentation tank and waste liquid is collected. Used for gas agitation.

化液の返送量は20％程度とするのが適当である。A part of the digested liquid discharged from the methane fermentation tank after the completion of the methane fermentation treatment is returned to the solubilization tank, and the remainder is added with an appropriate amount of a polymer coagulant and transferred to the coagulation tank. In this case, it is appropriate that the amount of digested juice returned is about 20%.

Separated as sludge. On the other hand, the supernatant liquid from which the solids were separated and the separated liquid from which the sludge was separated were combined and had a BOD of about 3000 mg /
Then, after diluting with water so that the CCD becomes about 500 mg / or less, it is introduced into an aeration tank, and aeration treatment is performed until the BOD removal rate is about 98% or more and the COD removal rate is about 90% or more. Then, the purified liquid after the aeration treatment is transferred to the settling tank, stays for a predetermined time, and is then sterilized with a germicide and discharged. The solid precipitated in the precipitation layer is returned to the flocculation tank.

According to this, it can be seen that the waste liquid is maintained at a slightly alkaline pH 7.5 to 8.0, which is favorable for methane bacteria,
And gasification rate was about 0.5 except for one week immediately after the start of treatment.
It can be seen that the gasification rate tends to gradually increase with the passage of days.

As the inorganic fertilizer, any of various chemical fertilizers containing one or more of N, P, K, Fe, Zn, and Mn can be used. It is desirable that the compounding amount of the inorganic fertilizer is about 13% or more per VS of the waste liquid of barley shochu, and if less than this, a remarkable improvement effect is not seen.
