Description

Detailed Description of the Invention

  The present invention relates to a solidified material obtained by solidifying shochu waste liquor with cement. Specifically, fishing reef blocks, reef paving stones, tetrapots, embankments, submarine floors, lures, fish bowl tools, pond beds, and fish farms The present invention relates to a solidified material for collecting fish that can be used for sardines, fishing tools, salmon, etc., and a method for producing the same.

In recent years, shochu liquor has been banned from being dumped into the ocean and buried as industrial waste, and attempts have been made to process it into fertilizer and feed. However, since a large amount of shochu waste liquid is discharged at a time from November to February of the following year, it is difficult to process a large amount of this at this time. In addition, the waste liquor of sweet potato shochu (see Photo 1, Table 1) has an extremely high affinity for water and cannot be centrifuged (separate water and solids). It is extremely difficult.

  Conventionally, for example, Japanese Patent Application Laid-Open No. 2002-342570 is characterized in that shochu distilled spirit and fresh concrete sludge are mixed to make the mixture almost neutral, and the distilled spirit in this mixture is used as a fertilizer component of a plant. A soil amendment material is shown. Japanese Patent Laid-Open No. 2002-346499 discloses a method in which shochu and fresh concrete washing sludge are mixed to neutralize the shochu, and the shochu is fermented with a fermentation active solution and activated. It has been shown that processed materials such as soil improvement materials and germination promotion materials can be obtained by mixing or stone powder.

  However, in the above-mentioned conventional method, the step of evaporating and solidifying the ready-mixed concrete cleaning sludge in the sun, the step of crushing the solidified sludge, the step of screening the crushed sludge, and the step of aligning the particle sizes (Japanese Patent Laid-Open No. 2002-346499) It takes a long period of time to obtain the invention, such as the description in column 2 [0008]), and the manufacturing process is bulky and complicated. Also, it is difficult to process a large amount of shochu liquor at a time.

  Furthermore, Japanese Patent Laid-Open No. 63-264185 discloses that the waste liquid of shochu is solid-liquid separated to adjust the hydrogen ion concentration of the liquid component to about 5-6, then the flocculant is added to solidify the dissolved component, and then the solid-liquid again. There is provided a method for treating a waste liquid of shochu, which is obtained by separating and mixing the obtained final liquid with cement and gravel to obtain a concrete molding.

  However, because it is a concrete molding after solid-liquid separation of shochu waste liquid twice, the process is extremely complicated, and all the fibers in the waste liquid are filtered, so it is almost water, nutritional components and fiber etc. There is no content of the soot, and it does not become a porous shochu waste liquid solidifying material rich in nutrients, which is the effect of the present invention as described later.

Furthermore, Japanese Patent Application Laid-Open No. 2002-125511 provides a fish reef characterized in that moromi mash is mixed with cement, mortar, soil and other solidifiable mixed media and molded and solidified. ], The moromi koji is a by-product in soy sauce production, and moromi koji in this invention includes amino acid fermentation by-products, tofu koji, sake lees, etc. in addition to soy sauce koji, and is not limited to soy sauce koji .

However, because the moromi mash of this invention is not a shochu waste liquid, it has little attraction effect, so it does not have an excellent fish collection effect and does not contain vitamin E. It is not effective for maintaining the health of fish, shellfish, sea urchins, sea bream, shrimp, sea bream, etc. Further, since the salt content (refer to the cited reference publication (see [0016] line 5) is contained in an amount of 0.1 to 20 wt%, the solidification of the cement cannot be obtained, so that a solid material with high strength cannot be obtained. Since the moromi of the invention has little water, it cannot be solidified unless water is replenished.

Problems to solve the invention

  The present invention can solve the above-mentioned drawbacks, and provides a method in which the production process is extremely simple and a large amount of shochu liquor can be treated at a time. In addition, the solidified material produced by this method activates the fish in the fishbowl sensitively, and continues to survive for a long time even if the food is conserved, and the water in the fishbowl is purified without becoming cloudy. Was found as a result of the experiment. The present invention provides a solidification material for collecting fish and a method for producing the same effective for collecting such fish.

Means to solve the problem

The invention of claim 1 is obtained by solidifying a sweet potato shochu waste liquor with a solidifying agent, having a compressive strength of 1.390 ± 0.0200 N / mm ² or more, and at least protein and vitamin E in the sweet potato shochu waste liquor. The solidification material for fish collection which consists of a strongly alkaline porous body containing the nutrient component of this and an appropriate quantity of fiber is provided.

In the present invention, when a strong alkaline solidifying agent (about pH 13.22) and a strong acidic sweet potato shochu waste liquor (about pH 3.85) are mixed at a constant ratio (a ratio of claim 2) to solidify them. In addition, the solidified material becomes strongly alkaline, and the water quality around the solidified material can always be improved to alkaline. In addition, it has an outstanding fish collection effect due to the synergistic effect of containing at least protein and vitamin E nutrients in the sweet potato shochu waste liquid and being a strongly alkaline porous material. As a result, water purification, maintaining the health of marine organisms, and increasing activation enable long-term survival, resulting in a tremendous effect of increasing the reproduction rate. In addition, since it has a compressive strength of 1.390 ± 0.0200 N / mm ² or more, it can be solidified for fish collection with excellent strength and durability without being easily collapsed by ocean currents even when used in the sea. .

The invention of claim 2, in strongly acidic sweet potato shochu effluent containing the nutrients and an appropriate amount of fibrous least protein and vitamin E sweet potato shochu in the waste solution, by mixing strongly alkaline solidifying agent and sand, this strongly alkaline solidified strongly acidic sweet Potato shochu waste respect agent 1: sand = 0.4 to 1.3: a mixing ratio of from 0 to 2.8, and to have a 1.390 ± 0.0200N / mm ² or more compression strength It provides a method for producing a solidified material for fish collection, which is characterized by solidifying into a strongly alkaline porous material.

In the present invention, the solidified material is made strongly alkaline by setting the mixing ratio of strongly acidic sweet potato shochu waste liquid: sand = 0.4 to 1.3: 0 to 2.8 with respect to the strong alkaline solidifying agent 1. I can do it. Further, the presence of an appropriate amount of fiber in the sweet potato shochu waste liquor and the solidification material by setting the mixing ratio of sweet potato shochu waste liquor: sand = 0.4 to 1.3: 0 to 2.8 with respect to the solidifying agent 1 The compression strength of can be increased to 1.390 ± 0.0200N / mm ² or more. In addition, because the amount of candy mash shochu waste liquid input increases, it is possible to use a large amount of candy mash shochu waste liquid at a time, to process a large amount of candy mash shochu effluent at once, a strongly acidic waste It can greatly contribute to processing problems.

Experimental example 1

  Water and a commercially available cement as a solidifying agent and commercially available sand were mixed at a weight ratio of 1: 2: 5, filled in a mold, and dried in the shade for 1 day. Solidified well after 3 days.

  On the other hand, sweet potato shochu waste liquor, commercially available cement and commercially available sand are mixed at a weight ratio of 2: 2: 5 (sample No. 3), packed in a mold, sun-dried for 3 days, and then dried quickly. In order to remove the mold. Solidified well after 6 days (see Photos 2, 3 and 4).

This indicates that the sweet potato shochu liquor cures well with twice the amount of water. In addition, when the cross-sections of the solidified material solidified using water and the solidified material solidified using the sweet potato shochu waste liquid are compared, the solidified material solidified using the sweet potato shochu waste liquid is more porous. It was of a quality and did not contain many holes with a diameter of 2 mm or more. The porosity of the cross section of the solidified material solidified using water could not be observed with the naked eye. In addition, the solidified material solidified using the sweet potato shochu liquor was a large porous material, but it was light and hard, and it was finished with a solid material that did not easily lose its shape.

Experimental example 2

  Commercial cement and commercially available sand were mixed as water and a solidifying agent in a weight ratio of 0.37: 1: 1, filled in a mold and dried in the shade for 1 day. Solidified well after 3 days (see Photo 5).

  On the other hand, sweet potato shochu waste liquor, commercially available cement and commercially available sand are mixed at a weight ratio of 0.65: 1: 1 (sample No. 2), packed in a mold, dried in the sun for 3 days, and then dried. The mold was removed to speed up. Solidified well after 6 days (see Photos 6 and 7).

This indicates that the sweet potato shochu liquor cures well with twice the amount of water. In addition, when the cross-sections of the solidified material solidified using water and the solidified material solidified using the sweet potato shochu waste liquid are compared, the solidified material solidified using the sweet potato shochu waste liquid is more porous. It was of a quality and did not contain many holes with a diameter of 2 mm or more. Moreover, the weight was about 10% lighter with the same capacity. The porosity of the cross section of the solidified material solidified using water could not be observed with the naked eye. In addition, the solidified material solidified using the sweet potato shochu liquor was porous, but it was lightweight (see Photo 8) and finished with a solid material that was high in hardness and hard in shape. It is considered that the strength deteriorates when many holes having a diameter of 2 mm or more are included.

Experimental example 3

Among the solidified material using water obtained in Experimental Examples 1 and 2 above, the solidified material (sample No. 2 and No. 3) using the sweet potato shochu waste liquid, and the solidified material, without using sand, In order to measure the pH value and strength of the solidified material (No. 1) using only cement, it was measured with a pH meter (see Photo 9) and a compressive strength tester (see Photos 10, 11, and 12). A comparative survey was conducted (see Tables 2 and 3).

The pH values of all the three solidified material samples using the solidifying agent and the sweet potato shochu liquor ranged from 12.68 to 12.96. Incidentally, the pH of the sweet potato shochu liquor was 3.85, and the pH of the cement was 13.22. Further, the compressive strength of the three samples was 2.1 ± 0.35 (N / mm ² ), the hardest solidified material (No. 1) using only sweet potato shochu waste liquor and cement. In addition, although the strength of general building concrete blocks is 4 N / mm ² or more, it is considered that there is no problem in strength or the like in the solidified material for fish collection this time. In addition, it is thought that intensity | strength can be hold | maintained if the mixture ratio of shochu waste liquid: cement: sand is about 0.4-1.3: 0 to 2.8 with respect to cement 1.

Experimental Example 4

Divide the solidified material using water obtained in Experimental Examples 1 and 2 above and the solidified material using sweet potato shochu waste liquid into small pebbles, and lay them in place of activated carbon in the purification section of separate water tanks with goldfish A small fishing reef was also installed in the tank (see Photo 13).

  Continuous observation of aquariums using solidified material made from sweet potato shochu liquor showed that goldfish gathered in small reefs and the movement of goldfish became much more active than before. After that, I have been observing the situation for a month without feeding, but the goldfish is still weak and still healthy. Surprisingly, if the aquarium does not change water for several days, green algae will adhere to the bottom of the aquarium and the surrounding glass. On the contrary, the water in the tank itself was increasing in transparency day by day.

  For these causes, we are currently conducting experiments and tests. However, goldfish gather in the solidified material, and nutrients such as proteins (amino acids such as lysine, arginine, glutamic acid, glycine, alanine, aspartic acid) and vitamin E It is inferred that the sweet potato shochu liquor containing

  The reason why green algae do not adhere to the bottom and surrounding glass of the aquarium or the transparency of the water increases is that the green algae are phytoplankton and freshwater green algae, and if a filtration device is not used Causes water to become cloudy. Because phytoplankton and freshwater green algae are propagated using goldfish urine, the bacteria are not attached to the aquarium glass or the transparency of the water is increased because bacteria are phytoplankton and freshwater. This is thought to be due to the decomposition of the green algae

  Bacteria tend to adhere to porous materials, so if such materials are placed in a water tank, the number of bacteria tends to increase. In the case of a solidified material using sweet potato shochu waste liquor, it is considered that bacteria are more effective than other substances because there is a possibility that bacteria adhere to themselves. If the purification effect decreases, the purification effect can be recovered by cracking the solidified material.

  On the other hand, there was no reaction with the solidified material using water. In other words, the glass in the aquarium became dirty as before, and the water in the aquarium was becoming less transparent.

  In this way, when the solidification material for fish collection is put into an aquarium or seawater, the fish reacts sensitively and collects in the solidification material, and the fish itself becomes active and becomes energetic. It continues to survive, and the water in the fishbowl can be purified without becoming cloudy.

Experimental Example 5

  In order to further demonstrate the purification effect of Experimental Example 4 above, green algae (plants) were placed in two pottery pottery filled with tap water and a plastic container filled with sweet potato shochu waste liquid solidification material and left in the field. We observed the occurrence of sex plankton and freshwater green algae).

As a result, green algae usually started from the third day, but even after 1 month had passed, there was no green algae and the purification effect was confirmed. (See photos 14, 15, 16)

Experimental Example 6

In order to investigate the purification effect of the sweet potato shochu waste liquid solidification material, the solidification material using the sweet potato shochu waste liquid demonstrated in Experimental Example 4 and the solidification material using water were installed in two filtration device purification sections. The water tank, and the pottery ware No. Water was collected from 1 and a plastic container.

Samples were sequentially set as (1), (2), (3), and (4) (see photographs 17 and 18), and the pH value was measured with the pH meter of photograph 9. (See Table 4)

At the same time, the state of bacteria in water was observed under a stereomicroscope (× 100) (see Photo 19).

  First of all, it was found that the alkalinity of the samples (1), (3), and (4) with a solidified material using the sweet potato shochu waste liquor was slightly high.

  The cause of this is thought to be the dissolution of the solidified material from the waste sweet potato shochu liquor, which is porous.

  On the other hand, the water samples (1), (2), (3), and (4) observed with a stereomicroscope do not show any difference and need to be studied from another point of view.

Experimental Example 7

  In Example 5 above, “When the solidification material for collecting fish is put into an aquarium or seawater, the fish reacts sensitively and collects in the solidification material, and the fish itself becomes active and healthy. In order to investigate the cause of this, when the sweet potato shochu waste liquor solidified material was finely crushed and fed into the ponds, all the groups were eaten up. This supported the reasons described above.

The invention's effect

In the invention of the product of the present invention, by mixing a strong alkaline solidifying agent and a strong acidic sweet potato shochu waste liquid at a certain ratio, when these are solidified, the solidified material becomes strongly alkaline, and the water quality around the solidified material is increased. It can always be improved to alkaline. In addition, it has an outstanding fish collection effect due to the synergistic effect of containing at least protein and vitamin E nutrients in the sweet potato shochu waste liquid and being a strongly alkaline porous material. As a result, water purification, maintaining the health of marine organisms, and increasing activation enable long-term survival, resulting in a tremendous effect of increasing the reproduction rate. In addition, since it has a compressive strength of 1.390 ± 0.0200 N / mm ² or more, it can be solidified for fish collection with excellent strength and durability without being easily collapsed by ocean currents even when used in the sea. .

  Accordingly, the invention of the present invention includes fishing tools such as reef blocks, reef paving stones, tetrapots, embankments, submarine floors, lures (see Photo 20), fish bowl tools, pond beds, fish farms It has an incentive effect and collection effect for all fish such as cormorants and can purify water.

Moreover, in invention of the manufacturing method of this invention, it is a solidification material by setting it as the mixing ratio of strong acidic sweet potato shochu waste liquid: sand = 0.4-1.3: 0 to 2.8 with respect to the strong alkaline solidification agent 1. Can be made highly alkaline, and the compressive strength of this solidified material can be increased to 1.390 ± 0.0200 N / mm ² or more. In addition, because the amount of candy mash shochu waste liquid input increases, it is possible to use a large amount of candy mash shochu waste liquid at a time, to process a large amount of candy mash shochu effluent at once, a strongly acidic waste It can greatly contribute to processing problems.
