2. Description of the Related Art Conventionally, in order to purify water quality of lake water, river water, etc., various purifying equipments and purifying devices have been used to conserve water quality. The recovered materials recovered from this lake water and river water by water purification treatment are mostly algae such as filamentous algae and floating algae that develop and multiply in lakes and rivers, and nitrogen, phosphoric acid, potassium, crude protein, crude fiber, etc. include. These collections are currently not available for use and are being abandoned. However, the algae contained in these recovered substances do not deteriorate or decompose in the water purification device and give off a bad odor, but at the same time they are collected from the purification device for recovery, and at the same time decay progresses and they are transported and dried. Sometimes it gives off a foul odor and it deteriorates. In particular, when filamentous algae are dried in the sun, they retain water because of the small diameter of filamentous algae plants and have poor air permeability. There is concern about the environmental impact of the disposal.

[Means for Solving the Problems] As a result of earnest research aimed at eliminating the defects of the water purification and recovery product containing algae and effectively utilizing it, the present inventors have found that photosynthetic bacteria, actinomycetes, etc. By removing the filamentous fungus that adheres,
It was found that they have an antagonistic effect against the effects of algae such as spoilage and deterioration, and that nitrifying bacteria, denitrifying bacteria, etc. have the effect of eliminating bad odors such as ammonia odor, and these bacteria are added to the collected product as antagonistic microorganisms. This completes the present invention.

The present invention relates to a method for producing an organic material, which comprises adding an antagonistic microorganism to a water purification and recovery product containing algae such as filamentous algae, floating algae, etc., dehydrating and drying, and yeast to this organic material. Is a method of producing an organic fertilizer, which comprises fermenting.

As the water purification product containing algae of the present invention, a product containing filamentous algae collected by a conventional water purification apparatus used for water purification of lakes and marshes, and the present inventors have previously invented the present invention. Pumice filter device (see Japanese Patent Application No. 6-45944)
The algae include filamentous green algae such as Ao mikuro, Hisaori, Sayamidoro and Amidoro, and filamentous diatoms such as Melosila, Fragilaria and Diatoma.

As the antagonistic microorganisms used in the present invention, filamentous fungi such as photosynthetic bacteria, actinomycetes, nitrifying bacteria, denitrifying bacteria and the like, which have exterminated filamentous fungi adhering to the cell wall of floating algae, ammonia odor and hydrogen sulfide odor, can be used. It is a microorganism that can be erased. The above-mentioned antagonistic microorganisms can be added to the raw material of the water purification product by mixing a solution of the antagonistic microorganisms with a filamentous or dry slurry-like raw material in which algae such as filamentous algae and floating algae are visible to the naked eye. In this way,
The alga-containing raw material to which the antagonistic microorganism is added is dehydrated and dried later. This dehydration and drying is a method carried out in order to make the processed product into a storage state and shape suitable for use as an organic material. As the means, generally used dehydration and drying methods can be appropriately used. The temperature of the drying treatment is preferably about 60 ° C. for filamentous green algae, and about 40 ° C. for filamentous diatom. When filamentous green algae are used as filamentous algae, it is more convenient in terms of work to cut the filamentous algae into several centimeters by a high-speed cutting machine or the like after dehydration during the above process. It is not necessary to cut the filamentous diatom.

The organic material produced by the present invention contains a large amount of nutrients necessary for plant growth such as nitrogen, phosphoric acid and potassium, and is therefore used as an organic fertilizer. Further, since it contains a large amount of active ingredients necessary for animal growth such as crude protein and crude fiber, it is effectively used as a feed for livestock and fish. In addition, it can be used for various purposes.

When the organic material of the present invention is used as an organic fertilizer, yeast is added to the organic material obtained as described above to ferment it to decompose algae's fibers so as to have a large amount of fibers. The effect of organic fertilizer is increased. Next, examples of the present invention will be described.

Example 2 A ceramic is added to the organic material obtained in Example 1, yeast and amoeba are further added, and the mixture is stirred at high speed for about 10 minutes until the water content becomes 45 to 50% by weight. In this step, excess water is adsorbed by adding ceramics, and filaments of filamentous algae can be divided by high-speed stirring. The organic material that has been subjected to high-speed stirring is placed in a semi-enclosed low temperature fermentation tank and low temperature fermentation is performed for 7 to 10 days. The peak temperature of this low temperature fermentation is 60-65 ° C. When the temperature rises above this temperature, the fermentation is stopped by stirring the filamentous algae and removing the fermentation gas. After the completion of this work, the treated product is taken out, subjected to particle size selection, packed in a bag, completely sealed, placed in a culture room at 15 to 20 ° C, stored in a standing state for about 2 weeks to 1 month, and continued fermentation.
