Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a method for efficiently collecting methane gas by converting plant, animal organic resources and livestock waste resources into raw materials to be supplied to a methane gas generator through an aerobic fermentation operation for recycling. Further, the present invention relates to a technique for composting residues.

2. Description of the Related Art Waste products, which are by-products produced as a result of living and industrial activities, are increasing and imposing loads on the environment. However, attempts to convert methane gas into methane gas by anaerobic fermentation to recycle and recycle it are extremely likely, and competition has been extremely high, and the number of development proposals has increased significantly. However, in many cases, the chemical trend is extremely large, and there are few small and many equipment methods that can be used immediately in the area where the raw material resources are generated. There is little integrated resource recycling technology until it is transformed into cultivated land and its appearance is required.

Aerobic fermentation and anaerobic fermentation are two perfect fermentation systems in the material cycle on the earth. Methane gas is a useful product among the products of the decomposition of organic matter, synonymous with the anaerobic fermentation. Recently, from the standpoints of both the merits and demerits related to the fundamentals of human survival, such as environmental protection, material circulation, and energy measures, technology that maximizes the scientific framework for the generation and use of methane gas has been proposed as a means of solving the problem of recycling industrial waste resources. ing. The present inventor also considered basic factors related to fermentation in order to narrow down the problem. That is, fermentation, whether aerobic or anaerobic, is a lawful reaction of enzymatic microorganisms. Most of the material cycle has a maturation as the top of the biosynthetic reaction of the plant, and there is a way to return to the soil beyond it. It goes without saying that unless the law-based biochemical reaction of the enzyme microorganisms functions, it will not be feasible. In other words, the reaction event for efficient methane gas generation required by the present invention depends on the quality of the raw materials supplied and the facilities to be treated. It was found to be due to a synergistic reaction with the microbial environment as well as the device. The idea of this proposal is to find out how much methane gas can be obtained efficiently if there is a raw material to be supplied to the methane gas generator, and how there should be a resource recycling technology to make the residue into effective and compostable arable land.
We propose a stepwise processing system.

Means and Action for Solving the Problems The inventor of the present invention applied for Japanese Patent Application No. Hei 8-144810 in 1996 as a resource recycling technology based on Japanese Patent Application No. 3044432/1990.
A plurality of field cultivations (5ha) based on the organic fertilizer produced by the method described in the examples based on the resource recycling and the production method of the bioactive organic fertilizer of Japanese Patent Application No. 2000-301228 filed by improving the method are disclosed. I tried and came across an event where I could believe reliable reproducibility. That is, the prior application technology aerobic fermentation treatment of food processing residues as industrial waste resources using specific enzymes as fermentation initiators,
An organic fertilizer made by adding multiple types of organic materials to an organic fertilizer by adding multiple types of organic materials to a material in which useful microorganisms have grown and the target material has been modified (minerals have been produced). Things. When applied to a paddy field, the expression of photosynthetic flora (axle algae) is remarkable, and when applied to a field, the formation of soybean root bacteria is remarkable. The inventor has been using so-called “bokashi manure” technology based on low-temperature crushed hulls for more than 10 years ago. This year, the method using a specific enzyme (Eokomitsuto), in addition to the above-mentioned events, added algae in paddy fields. The typical anaerobic fermentation in the arable soil under the extremes has emerged. It was also a discovery that the anaerobic fermentation event that affected the entire soil was in line with the methane gas generation mechanism. Table 2 shows a description of the characteristics of the fermentation initiator eocommitt. In addition, the special humic substances newly used in the present application are unsaturated in structural formula, have base substitution ability, and furthermore, have a surfactant activity and an organic chelating effect function to assist fermentation decomposition, so that heavy metal accumulation by the food chain in the raw material The explanation of other raw materials, which could use fish and other wastes that could cause harm, is also detailed in the earlier application. The departure of the means of the present application (claim 1) is the same as the prior application, but the subsequent means increases the ratio of animal dung and garbage and turns it into a raw material through aerobic fermentation, and pursues anaerobic fermentation extremely under completely anaerobic conditions. Gas is collected, and the residue is also a technique that can be turned into an effective and highly active fertilizer. The aim of the dimension of the present application is that aerobic fermentation is said to decompose and reduce the amount of organic material, but anaerobic fermentation cannot reduce the amount of organic material, and that eocommit used as a fermentation initiator was confirmed in the aforementioned multiple fields. The aerobic fermentation product strongly assists anaerobic fermentation under anaerobic conditions, and at the same time, has characteristic information that it has the ability to reduce heavy metals as a result of fermentation. In view of the fact that there is characteristic information to increase the ion phosphorus san ion, by increasing the compounding of dangerous nitrogen-transporting materials for the purpose of direct fertilizer, the initial stage Methane gas is generated efficiently by chelating effect decomposition. In addition, materials similar to humus, which is a residue generated as a result of methane gas collection, can be further aerobic fermented and returned to the field as a compost with a good soil improvement function with a low nitrogen content. Become. To sum up, organic fertilizers made through a staged aerobic fermentation operation that started with a concoction between a residual resource obtained by processing a mature plant and a specified enzymatic agent (eocomit) contain minerals. It manifests the organic chelating effect and realizes a phenomenon called environmental purification. On the other hand, as an organic fertilizer, the fermentation product of the present invention, in which the proportion of material that causes nitrogen excess is increased, is supplied as a raw material for a methane gas generator, and methane gas is generated by efficient anaerobic fermentation. As a result, the recycling and recycling of food residue resources has been greatly advanced, and it has also greatly contributed to eliminating imbalances in the nitrogen circulation system. Finish with a compost that increases. As described above, the product obtained by the aerobic fermentation operation using the resources and materials used in the present application as a raw material is a product obtained by aerobically fermenting a mixture of a large amount of nitrogen transfer resources, based on the characteristic that an organic chelating effect appears. Is supplied as a raw material to a methane gas generator, which is a typical anaerobic fermentation, and methane gas is efficiently collected and used, and the residue is returned to the soil by aerobic fermentation by adding the purification power of the soil again. A resource recycling system using both aerobic and anaerobic fermentation systems is completed. Table 1 shows a chromatographic chart in which a product obtained by a method for producing a soil activator from a mature plant resource, which was based on the prior application, which was filed on September 13, 1990 (Patent No. 30444326), was based on the present invention ( Various amino acids are produced and mineralized.) In addition, Table 2 shows the description of the characteristics of Ecomit, a fermentation initiator which has greatly advanced the technique of the present invention.

The raw material A-4 was obtained by aging through aerobic fermentation including forced air blowing at a temperature zone of 65 ° C. or lower.

Example 6 Raw material and animal urine 10 produced by the above examples
20 liters of a 200-fold solution of Ecommitt per 100 liters is added to the methane gas generator of the continuous temperature-maintaining berth together with the urine whose ammonia smell has been reduced by explosive treatment and expelled from the fermentation termination tank. The residue was dehydrated, and water was adjusted for excess water with crushed peaches.
20 kg of shell fossils, 25 kg of rice bran, 10 kg of krill and 20 kg of madraguano are added per 0 liter, and 10 liters of a 200-fold solution of eocomit are dispersed and kneaded and mixed. Activated compost was obtained by aging through aerobic fermentation. As mentioned above, the model raw material treatment according to the raw material and the production method of turning the residue after methane fermentation into active compost have been described. If it is a small scale, it is naturally possible to mix and process a plurality of raw materials, but if it is re-listed, the basic bacterial flora material fermenting a plurality of plant fiber resources with a 200-fold solution of the eocommitant according to the method of Example 1. , Specifically, the siliceous substance is activated to generate minerals,
It is considered that the vitality continued in the next-stage treatment and an organic chelating effect was exhibited. Raw materials that have undergone decomposition and reforming of organic matter along with the evolution of the microflora by multi-stage aerobic fermentation undergo large reforming in response to strong anaerobic conditions and generate methane gas, and the residue is activated. It is expected that the compost becomes almost humus due to the gas fermentation treatment, and that the harmful substances are reduced to below the environmental load level by the synergistic action of Eocomit and Marinex.

It has been more than 10 years since trials have been carried out after noticing that low temperature crushed firgrass has a major role in the return decomposition of mature plant resource material-that is, the law-based decomposition system that returns to soil. Most of the organic resources in the streets have the potential to participate in the circulatory system as precious resources based on the technical idea. If this application were a step closer to the completion of the ecosystem cycle, we would have to look to the qualities of the resources that nature has left behind today, thanks to the world's need for them. The categories of aerobic fermentation and anaerobic fermentation in the material cycle are wide, and there are many materials that are said to correspond to them. However, it is significant that the events leading up to the present invention have shown that reactions in nature are not as distinct as words. That is, in the material cycle, aerobic fermentation greatly changes the quality while reducing the amount of material, but anaerobic fermentation does not significantly reduce the amount of material, and the phenomenon that drastically changes the quality is clear, called digestion. This is true. When the fermentation is carried out by combining a plurality of materials mainly containing a large amount of plant fiber leading to the present invention and adding a specific fermentation initiator enzyme, the silicic acid therein is activated to generate minerals, and secondary and tertiary. The fermentation, which also includes animal quality, has very little off-flavor due to the decomposition of protein, and is close to the reaction in healthy soil. When the aerobic fermentation product which has been processed as a raw material based on the present invention is subjected to severe anaerobic conditions, it undergoes extreme anaerobic fermentation adapted to the environment.
(The anaerobic fermentation state under the algae that occurred in the paddy field described above is remarkable by thorough deep water management.) The natural philosophy of the nature of the present invention in the natural world is a new development in the industrial development of the resource recycling cycle in the material cycle. It is an event that inspires the possibility and can greatly contribute to the industry centered on it.
