In FIG. 1 and FIG. 2, first, a waste floor containing mushroom mycelium as a cultivation base resulting from mushroom cultivation, charcoal made into powdered charcoal, a microorganism comprising at least lactic acid bacteria and yeast, and water are mixed. A predetermined ratio, for example, 100 g of waste floor, 0.5 g of charcoal, 0.1 g of a microorganism composed of at least lactic acid bacteria and yeast as a liquid, and 30 g of water are mixed and stirred. Yeast: photosynthetic bacterium = 3: 1: 1 ratio as required,
Also, if necessary, about 0.3 g of charcoal of the paddy is added, and the mixture is stirred for a predetermined time, for example, about 24 hours (about 1 day), and the mixture is generated by friction generated by the stirring and spontaneous heat generation due to power heat. Is fermented and decomposed.

In this case, the stirred fermentation section H is stirred by a stirrer 1 as shown in FIGS. 3 and 4, and this stirrer 1 has a rotating shaft 3 installed in a container body 2 and a plurality of rotating shafts 3 A plurality of stirring blades 4 protrude, the rotating shaft 3 is rotated by a motor 5, and the mixture is stirred by the plurality of rotating blades 4.

Next, the mixture W fermented and decomposed by the heat generated by the stirring and mixing is weighed out of the container 2 through the outlet 6, and specifically, the fermentation degree is 70%.
The bag is filled with a bag made of a synthetic resin or the like in a bag-filling section F. In the ripening section K, the bag is aged for a predetermined number of days, for example, about 20 days at room temperature, and aged. The fermentation degree is set to about 80 to 90%.

Then, the aged mixture is dried in the drying section M by natural drying or forced drying to produce a sewage treatment material.

At this time, for example, when the material is used immediately as a sewage treatment material without leaving a time, the moisture content is made to be a freshly dried state having a water content of about 45%. Is a dry state having a water content of about 15% so that it can cope with aging.

In this embodiment, a waste floor containing mycelium of mushrooms, charcoal, a microorganism comprising at least lactic acid bacteria and yeast and water are mixed and stirred at a predetermined ratio, and the mixture is formed by stirring for a predetermined time. The mixture is fermented and decomposed by heat generation, and the fermented and decomposed mixture is packed in a bag, left to age for a predetermined number of days, aged, dried and manufactured, and this sewage treatment material is taken out of the bag and sprayed into water. Or put in water in a net bag or a bag with holes, or put it into water by compression molding and put it in water as a pellet-like solid. And it has the antioxidant power that does not rust iron and has the high resilience of filth that stops the progress of decay and restores to the original organic matter, so even a small amount, a large amount of sewage,
It has the ability to purify wastewater, and has the same convenience for both storage type and running water type used in reservoirs, etc., which can increase the flexibility of use, and is also recyclable, economical and inexpensive. It also has high supply stability, environmentally friendly, natural recycling type recyclability and strong iron rust prevention,
Furthermore, since the low-temperature fermentation decomposition ability in the range of about 20 ° C. to 30 ° C. is excellent, it is possible to use 70 ° C. to 9 ° C.
The aging can be performed without requiring a high temperature of about 0 ° C., and the production can be performed more easily and at low cost.

[0015] As a specific example, the results of using the wastewater drainage tank drained from a mushroom factory as follows.

The size of this water storage tank is 40 m long × 3 m wide.
× A water tank with a depth of 25 cm is composed of two tanks, the amount of water is about 50 tons, the water temperature is 25 ° C to 40 ° C, the average water temperature is about 30 ° C, and at first, a net bag containing 15 kg of the wastewater treatment material is used. Put a total of 45 kg and leave it for one month, then put two net bags containing 15 kg and leave it for two months and put in a total of 30 kg, then put a 15 kg net bag with 15 kg.
It was put in and left for one month.

As a result, a total of 90 kg of the sewage treatment material was charged, and one to two months after the start when 50 kg was charged, the sewage was purified and activated, and the initial PH value was 5 to 5. About 6 was maintained at 7 to 8 neutrality, and the odor was initially the worst odor of 4, but it became an odorless state with about 1 odor. Purify so that the generation and proliferation of oyster oysters, medaka, yago, fireflies, and other small organisms can be seen,
In addition, the effect of removing iron rust is also exhibited,
It is also known that microorganisms propagate by using the protein source as feed.On the contrary, there are disappearance of spoilage and algae that make water decay, and the residue of this wastewater treatment material after use is returned to soil. High, and unlike chemicals, there were no side effects or pollution.

According to the evaluation from a biological point of view,
The state where medaka, firefly, etc. inhabit and breed and inhabit is an ideal natural environment, and was evaluated as favorable.

Therefore, a natural environment recycling type industrial waste recycle material is developed, and the antioxidative fermentative decomposition ability of the mycelium and the microorganisms remaining in the waste floor is utilized. It can be said that the difficulty in decomposing the lignin and the fiber group (cellulose), which are the malignant substances in the waste floor, can be expanded by the rotary pressure stirring heat treatment method in a short time, for example, about one day.

In this case, since photosynthetic bacteria as microorganisms are added to the mixture, for example, in a waste floor after cultivation of maitake, the decomposition ability is promoted to increase the water purification ability. Since the charcoal of the paddy is added, the fermentation gas can be satisfactorily eliminated because of the porosity, and it also becomes a home for microorganisms, so that the water purification capacity can be increased accordingly.In this case, pulverized coal is used as the charcoal. Therefore, the fermentation gas can be satisfactorily eliminated because of the porosity, and at the same time, it becomes a home for microorganisms.

The present invention is not limited to the above embodiment, and the structures of the stirred fermentation section H, the bagging section F, the aging section K, and the drying section M are designed by appropriately changing. is there.

The mixture is stirred and mixed, and the mixture is fermented and decomposed by heat generated by stirring for a predetermined time.The fermented and decomposed mixture is bagged, left to stand for a predetermined number of days, aged, and the aged mixture is dried to produce a mixture. Take this sewage treatment material out of the bag and spray it in water, or put it in a mesh bag or a bag with holes, put it in water and use it, or compress it and mold it in water as a pellet-like solid. This sewage treatment material has the antioxidant power of preventing the decay of the material and the rusting of iron, and also has the high resilience of the filth to stop the progress of the rot and restore the original organic matter. Even in small quantities, it has a large amount of sewage and drainage purification capacity, and it has the same convenience even for storage type use and running water type use for reservoirs, etc., and can increase the flexibility of use, In addition, it has high recyclability, economic efficiency, low cost, and stable supply. It also has high environmental and natural recycling recyclability and strong iron rust prevention.
Since the low-temperature fermentation decomposition ability in the range of 0 ° C to 30 ° C is excellent, aging can be performed without requiring a high temperature of about 70 ° C to 90 ° C as in the case of using a chemical change. And it can be manufactured at low cost.

According to the second aspect of the present invention, a photosynthetic bacterium as a microorganism is added to the mixture.
For example, in the waste floor after cultivation of maitake, the water purification capacity is enhanced by promoting the decomposition ability. In the invention according to claim 3, since the charcoal of the paddy is added to the mixture, it is porous. Therefore, fermentation gas can be eliminated well and it also becomes a home for microorganisms.
Further, in the invention according to claim 4, since powdered charcoal is used as the charcoal, the fermentation gas is similarly favorably eliminated because of the porous nature, and also serves as a home for microorganisms. Can be.
