Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides chemical and/or biological attack by adding metabolites produced by the activities of aerobic and facultative anaerobic bacteria to an organic mixture. The formation of a substance and then the coexistence of the unreacted organic mixture and the above-mentioned chemical or/and biological sludge-like substances to form a lumpy product, and at the same time the metabolic process containing trace amounts of oxidizing enzymes remaining in the lumpy product. As a result of the action of the product, the growth and proliferation of microorganisms other than aerobic bacteria and facultative anaerobic bacteria is suppressed.
The present invention relates to a method for processing an organic mixture into useful substances by improving the quality and storage stability of the organic mixture.

As is well known, recovery and utilization of organic mixtures from aqueous solutions requires great expense and advanced technology, and as a result, they are often discarded unused. For example, although organic mixtures contained in food processing wastewater are generally high-quality food or feed materials, they are subject to wastewater treatment due to the lack of efficient recovery and processing technology. The mixture is subjected to lower level use or disposal as wastewater treatment sludge.

Similarly, solid or slurry organic mixtures are processed through the action of microorganisms to produce food and organic feed.

Processing methods into organic fertilizers, etc. are widely used.

All of these methods use processing methods that are sensitive to citrus, but for example, in the production and processing of organic fertilizers, organic raw materials such as dehydrated sludge are adjusted to a moisture content of about 55 to 65%, and at the same time, aerobic bacteria or facultative anaerobic It is fermented and processed by adding bacterial bodies consisting of a group of 1IrR bacteria and maintaining the temperature and aeration conditions for a long period of time at the optimum conditions for the 1IrR blank group to be added.

However, such conventional processing methods require a great deal of effort and expense to adjust the moisture content of organic raw materials.
In addition, fermentation requires a long period of time, therefore requires a vast amount of land, and its management also requires a great deal of effort. Incidentally, such drawbacks also apply to the processing of processed foods, organic feed, and organic feed raw materials.

This invention was made in view of the above circumstances, and has the purpose of making it possible to react in a short time, to process with little energy or land, and to stabilize and improve quality. It has been done.

The feature of this invention is that an organic mixture containing protein, carbohydrate, or a combination of protein, carbohydrate, and fat, with a fat content of 10% or less of the total organic mass, is oxidized by the activity of bacterial groups. By adding metabolites including enzymes, a chemical or/and biological sludge is formed, and then by the coexistence of the unreacted organic mixture with the chemical or/and biological sludge. At the same time, the growth and proliferation of microorganisms other than aerobic bacteria and facultative anaerobic bacteria is suppressed or inhibited by the action of the metabolites containing the oxidizing enzyme that form a lumpy product and remain in trace amounts in the lumpy product. As a result, the quality and storage stability of the organic mixture are improved, and it is only necessary that the water contained in the organic mixture is 30% by weight or more based on the amount of solids. Therefore, the organic mixture referred to here is
It may be in solid form, slurry form, or molten form (aqueous solution containing an organic substance). In addition, in the processing of organic substances in aqueous solution, the solid-liquid fraction l1lI in the processing process
Generally, t is required.

The bacterial group that produces metabolites containing oxidases that are added in the method of this invention includes Zoogloea
a) Aerobic bacteria group including urinary bacteria, bacteria of the genus Lactobacillus and Bacillus (Bac, 1llus); a group of facultative anaerobic bacteria including urinary bacteria, aerobic bacteria including urinary bacteria of Zoogloea and bacteria of the genus Lactobacillus and Bacillus ( Bacillus)
It may be any bacterial group that coexists with facultative anaerobic bacteria including urinary bacteria. The reason why the metabolites of all of these bacterial groups are effective in this processing method is that both aerobic bacteria and facultative anaerobic bacteria have metabolic circuits that function effectively in the presence of oxygen, and as a result, they are compatible with each other. This is because they produce metabolites that are similar and consist of substances that are both highly oxidized. The metabolites produced by aerobic and facultative anaerobic bacteria include compounds with exposed phenolic groups and oxidative enzymes, organic acids, polysaccharides, and amino acids, and the above chemicals are When added to the mixture, a chemical or/and biological sludge is formed, and the coexistence of this chemical and/or biological sludge with the unreacted organic mixture then produces a lumpy product. form.

Chemical and/or biological sludge-like substances 11f
2 and the reactions involved in the formation of bulk products are completely different from enzymatic reactions. In an enzymatic reaction, the molecular weight of the product decreases as the reaction progresses, but depending on the progress of the reaction, the molecular weight increases.

It is clear that the reaction consists of complex reactions such as aggregation, condensation, and 1M combination.

Furthermore, it has been experimentally confirmed that the metabolites of the above bacterial groups have a strong sterilizing or inactivating effect on microorganisms other than the above bacterial groups, that is, obligate anaerobic bacteria and viruses. As a result, the chemical and/or biological sludge produced by adding the above-mentioned metabolites to the organic mixture is anaerobic due to the action of the RQJ products remaining in trace amounts in the agglomerated products. The growth and proliferation of sexually transmitted bacteria is suppressed or inhibited, resulting in improvements in quality and shelf life.

The chemical compound product to be added may be a metabolite containing an oxidase grown by the above-mentioned bacterial group or a solution of the metabolite.

The amount of this sub-d11 product to be added may be small since the metabolite containing the oxidase functions as a nucleus during the reaction, and it will vary depending on the purpose and the mass of the organic component, but in general. is the amount of organic matter io, ooo
A range of 1/100 to 1/100 is sufficient. In addition, as long as the amount of the metabolite containing the oxidase is sufficient, it does not really matter what kind of substance it is added with. Is organic water the type of substance containing metabolites that is normally added? Examples include sludge-like substances and humus precursors produced by biological treatment of g-liquid. It is more effective to use a chemical 8!11 product containing an oxidizing enzyme extracted from a sludge-like substance or a humic precursor extracted from a humic precursor-containing substance,
Water, weak acids, and salts, water/8/&, are effective as extraction media. Here, the term "humic precursor" is a general term for substances in the process of converting organic matter into humus, and examples of humic precursors that are easy to extract in terms of amount and form include peat and humic plants. Humic plants are humus mixed with humus precursors, or humus mixed with humus precursors.
refers to something that exists.

The method of this invention will be further explained with reference to FIG. 1.
An organic mixture consisting of a combination of fats and having a fat content of 10% or less of the total organic mass is fed into the reaction step 1 continuously or discontinuously in fixed amounts. Then, from the additive supply tank 2, a fixed amount of the metabolite or a substance containing the metabolite is added to the reaction step 1. In the reaction step 1, these two substances with different properties are mixed and slowly stirred as necessary, so that chemical or/and A biological sludge is formed, and then the coexistence of the unreacted organic mixture with this chemical or/and biological sludge forms a bulk product, and at the same time the chemical or/and biological sludge is formed. Due to the action of the above-mentioned metabolites remaining in trace amounts in the substances and bulk products, the growth of microorganisms other than aerobic bacteria and facultative anaerobic bacteria is inhibited, improving product quality and producing new, stabilized reaction products. generated. The reaction time in reaction step 1 is generally several hours or less, and in order to further promote the reaction, it is effective to heat the reaction to a temperature of about 50° C. or lower.

Note that it is essential that the organic mixture contains 30% by weight or more of water, and as a result, the organic mixture may be in a solid state, a slurry state, or a molten state (an aqueous solution containing an organic substance). Also, chemical and/or biological sludge-like substances and lump products are formed by the reaction of these organic mixtures with additives and the like.

As a result of a trace amount of unreacted metabolites remaining in the above-mentioned lumped product, if necessary, the lumped product is allowed to stay for a certain period of time in the aging step 3 to prevent the growth of microorganisms other than aerobic bacterial groups and facultative anaerobic bacteria. At the same time, the growth and proliferation of the bacterial group is promoted, and the reaction progresses further. This means that metabolites produced by aerobic bacteria and facultative anaerobic bacteria, which have metabolic circuits that function effectively in the presence of oxygen, are the best environmental substances for these bacterial groups. It is clear that it is the worst environmental substance for microorganisms other than the relevant bacterial group, and it has been confirmed experimentally.

Under such conditions, a residence time of 72 hours or less is generally sufficient for the aging step 3.

In addition, when using humic plants as additives, the material is mined from the ground and left in the field for about 1 to 3 months, during which time it is cut several times to increase the amount of quinones, which are oxides of phenolic compounds. It is more effective to use it at the desired L. Similarly, as an aqueous solution of a humic precursor as an additive, a solution obtained by adding an aqueous solution of weak acids and salts in equal amounts or less to natural humic plants and separating the mixture by filtration is used. Since the humic precursor aqueous solution contains compounds with exposed phenol groups and oxidizing enzymes, by allowing the filtrate to stand for more than 24 hours after filtration, an increase in the amount of quinones is observed, and the humic precursor water/8 The reactivity of the fluid increases in the philtrum.

Furthermore, the effect will be even more pronounced if the pH of the organic mixture is adjusted to 5.0 to 7.5 after or before adding an appropriate amount of the additive in reaction step 1. Furthermore, when the organic mixture is in a dissolved state, a separation step is inserted between the reaction step 1 and the ripening step 3 to separate the bulk product from the liquid, and the separated bulk product is sent to the ripening step 3. It is common to do so.

FIG. 2 shows another embodiment of the method of the invention.

In this example, when the additive supplied from the additive supply tank 2 is a humic plant, a humic precursor is extracted from the humic plant and fed to the reaction step 1. In this case, it is desirable that the organic mixture be in dissolved form, and organic water containing this organic mixture? g/& was mixed and stirred with the humic plant supplied in advance from the additive supply tank 2 and extracted in the extraction step 4. After returning to the reaction step I and reacting with the organic aqueous solution, The lump product is sent to separation step 5 to be separated into a lump product and a waste liquid, and the lump product is sent to a separation step 9 as necessary.
! The first step is a step of ripening.

As is clear from the above explanation, the method of the present invention is characterized by the formation of lump products due to the synergistic effect of various chemical and physical reactions between an organic mixture and an additive consisting of a microbial metabolite or a substance containing a large amount of a metabolite. Processed products are obtained through the inhibitory effect on obligate anaerobic bacteria and viruses in the bulk product due to the action of microbial metabolites.
Even in the processing of solid or slurry organic mixtures, unlike conventional methods, it does not require any means or expense to process 1 jilQ of water, and it also does not require a short time or a large area of land, and can stabilize and improve quality. can be achieved.

Various basic embodiments of the invention will be described below.

Although humus precursors and humic plants were used as additives in the examples, the effect is almost the same even if sludge-like substances or peat produced by biological treatment of an organic aqueous solution are used instead. be.

(2) Pressurization of solid or slurry organic mixture and turning soybean cake into feed (Figure 1) Soybean cake (Okara) with a moisture content of 80% generated from the soybean milk manufacturing process is continuously fed at 10 t/h. A 2% aqueous solution of a humic precursor was added to the reaction tank at a rate of 10 hours, and a 2% aqueous solution of a humic precursor was added at a rate of 50% based on the organic matter in the soybean stalks, ie, 2000 ppm based on the organic matter in the soybean stalks. When the mixture was thoroughly stirred for 60 minutes after addition, the dehydration properties improved significantly, and dehydration to a water content of about 60% was possible using a regular filter cloth dehydrator without the addition of flocculants. . When given as livestock (cattle) feed immediately after dehydration and after being left for 30 days after dehydration, the feeding effect was good. Incidentally, no progress of rot was observed during 30 days at a moisture content of 60%. Furthermore, when humic plants were added in an amount of 10% based on the organic matter in the squeezed soybean stalks instead of the humus precursor aqueous solution, the same effect as described above was obtained.

By the way, soybean lees (Okara) spoils especially quickly, so be careful! Under conditions of about 25°C, it will rot in about 12 hours, making it impossible to use it as feed. Even with the addition of enzymes, the progress of decomposition cannot be stopped, so to date most of the waste has been thrown away.

Turning poultry manure into fertilizer (Figure 1) Chicken manure with a moisture content of 90%, adjusted to PL+ of 6.5, is continuously supplied to reaction tank 1 at a rate of 10 tons/10 hours, and one or more humus was added from the additive supply tank 2 at a ratio of 10% to the organic matter in the chicken manure. When heated and stirred at 40℃ for 1 hour after addition, the dehydration performance of chicken manure improved to 11, making it possible to dehydrate chicken manure to a moisture content of up to 70% without adding a flocculant in a regular cloth dehydrator. Ta.

The dehydrated chicken manure produced by this method does not produce any bad odor.
The fertilization effect was good and there was no rooting after fertilization.

By the way, in order to ferment the same chicken manure as mentioned above using the conventional method, it is first necessary to adjust the moisture content of the raw chicken manure to about 60% by adding a water regulator, and the fermentation period is about 30 days. It takes. It is impossible to prevent the occurrence of bad odors during the Shigamo fermentation period.
