  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

(First embodiment)
FIG. 1: has shown the schematic diagram which is 1st Embodiment of the microorganisms activation apparatus of this invention. This microbe activation apparatus includes an activation tank 1 that contains a micro-nano bubble generator 3 and a string-like polyvinylidene chloride filler 14 as a filler, an auxiliary tank 11 that contains a micro-nano bubble generation aid, and a nutrient. And a nutrient tank 13 for containing the.

  A microorganism-containing liquid containing microorganisms is introduced into the activation tank 1, contains micro / nano bubbles by the micro / nano bubble generator 3, is added with the micro / nano bubble generation aid from the auxiliary tank 11, and the nutrients are added. The nutrients are added from the agent tank 13, and the microorganisms in the microorganism-containing liquid are activated.

  Then, after the activated microorganisms are cultured and propagated in large quantities, they are used in the next process utilization process 15. Here, the microorganism-containing liquid refers to a liquid containing microorganisms in various industries.

  The activation tank 1 accommodates a turbidimeter 2 for measuring the turbidity of the microorganism-containing liquid. When the generation amount of micro-nano bubbles in the microorganism-containing liquid is appropriate, the microorganism-containing liquid becomes cloudy like milk, but when the generation amount of micro-nano bubbles in the microorganism-containing liquid is not appropriate, The transparency increases and the turbidity of the microorganism-containing liquid becomes low. That is, the turbidimeter 2 is for confirming the generation state of micro-nano bubbles in the microorganism-containing liquid.

  The string-like polyvinylidene chloride filler 14 is a medium for propagating microorganisms, and serves as an immobilization carrier for immobilizing and propagating activated microorganisms.

  An air suction pipe 6 is connected to the micro / nano bubble generator 3, and a valve 5 for adjusting the air suction amount is connected to the air suction pipe 6. Connected to the micro / nano bubble generator 3 is a circulation pump 7 for supplying water in the activation tank 1 to the micro / nano bubble generator 3.

  The micro / nano bubble generator 3 is supplied with water from the circulation pump 7 and sucks air from the air suction pipe 6 so that the water and air cause a swirling flow at an ultra high speed. Generate nanobubbles. And the said micro nano bubble generator 3 raise | generates the water flow 4 shown by the arrow.

  The opening degree of the valve 5 is adjusted according to the generation state of the micro / nano bubbles. If the valve 5 is throttled to reduce the opening of the valve 5, micro-nano bubbles are likely to be generated. On the contrary, when the opening degree of the valve 5 is increased, a general large bubble is generated without generating micro-nano bubbles. While this large bubble is stored as a bubble at the top of the water surface, micro-nano bubbles are stored on the water surface, but the amount is small.

  The micro-nano bubble generator 3 is not limited to a manufacturer as long as it is commercially available, and specifically, there is a product of Nano Planet Research Laboratory. As other products, there are, for example, a microbubble water production apparatus manufactured by Seika Sangyo Co., Ltd. and a microbubble water production apparatus produced by Resource Development Co., Ltd., but may be selected according to the purpose.

  Here, the micro / nano bubble refers to a bubble having a diameter of about 10 μm to several hundred nm. In addition, a normal bubble (bubble) rises in the water and finally disappears by popping on the surface. Microbubbles refer to bubbles having a bubble diameter of 10 μm to several tens of μm. They shrink in water and eventually disappear (completely dissolve). Moreover, nanobubble means the bubble which has a diameter of several hundred nm or less, and can exist in water forever. And it can be said that a micro nano bubble is a bubble which micro bubble and nano bubble mixed.

  The auxiliary tank 11 is connected to an auxiliary tank pump 10 for sending the micro / nano bubble generating auxiliary agent to the activation tank 1. The above-mentioned micro / nano bubble generation aid means one that can stably maintain the generation state of micro / nano bubbles. The micro / nano bubble generation aid is a surfactant. The surfactant is degraded by microorganisms, for example, in a few hours.

  The auxiliary tank pump 10 is connected to a turbidity controller 9 for controlling this operation. The turbidity adjuster 9 controls the operation of the auxiliary agent tank pump 10 based on the signal from the turbidimeter 2. That is, the auxiliary tank pump 10 is automatically operated by the signal line 8 through the turbidity adjuster 9 and the signal of the turbidimeter 2. Therefore, the generation state of micro / nano bubbles can always be stably maintained at the best state.

  The nutrient tank 13 is connected to a nutrient tank pump 12 that delivers the nutrient to the activation tank 1. Then, the nutrient tank is quantitatively added to the activation tank 1 from the nutrient tank 13 by the nutrient tank pump 12. The nutrient is a nutrient that contains nitrogen and phosphorus as main components and contains a small amount of potassium, magnesium, and calcium, and is necessary when microorganisms are activated.

  Next, a method for activating microorganisms using the microorganism activation apparatus will be described.

  The microorganism-containing liquid is introduced into the activation tank 1 containing the string-like polyvinylidene chloride filler 14. And in the said activation tank 1, while adding a micro nano bubble to the said microorganisms containing liquid, a micro nano bubble generation adjuvant and a nutrient are added, and the microorganisms in the said microorganism containing liquid are activated.

  The microorganisms are propagated stably and in large quantities on the surface of the string-like polyvinylidene chloride filler 14. This is because the string-like polyvinylidene chloride filler 14 is fibrous, and the surface area of the string-like polyvinylidene chloride filler 14 is large.

  Then, the activated large amount of microorganisms are introduced into the next process use step 15 and used according to the purpose.

  According to the microorganism activation apparatus having the above-described configuration, the activation tank 1 that houses the micro-nano bubble generator 3 and the string-like polyvinylidene chloride filler 14 and the auxiliary tank that contains the micro-nano bubble generation aid. 11 and a nutrient solution tank 13 containing the nutrient, and the microorganism-containing liquid is introduced into the activation tank 1 and contains micro / nano bubbles by the micro / nano bubble generator 3, The micro-nano bubble generating auxiliary agent is added from the auxiliary agent tank 11 and the nutrient agent is added from the nutrient agent tank 13 to activate the microorganisms in the microorganism-containing liquid. And it can be reliably increased.

  Moreover, since it has the said turbidity meter 2, the said auxiliary agent tank pump 10, the said turbidity controller 9, and the said nutrient solution tank pump 12, the said microorganisms activation apparatus can be manufactured easily.

  In addition, the turbidity controller 9 controls the operation of the auxiliary tank pump 10 based on the signal from the turbidimeter 2, so that the turbidimeter 2 can manage the generation state of micro-nano bubbles. Therefore, the optimum amount of micro / nano bubbles can always be maintained. That is, the generation state of micro / nano bubbles is proportional to the turbidity of the microorganism-containing liquid.

  Specifically, the turbidity controller 9 confirms the generation state of micro-nano bubbles with the turbidimeter 2, and when the generation state is bad, that is, when the micro-nano bubbles are insufficient, the turbidity is measured. Based on the signal from the total 2, the micro / nano bubble generation auxiliary agent is increased in conjunction with the auxiliary agent tank pump 10.

  Moreover, since the said string-like polyvinylidene chloride filler 14 is used as the said filler, the microorganisms activated by the said string-like polyvinylidene chloride filler 14 can be propagated stably and in large quantities.

  Moreover, since the micro / nano bubble generation aid is a surfactant, the surfactant can be easily and inexpensively procured.

  In addition, since the surfactant is decomposed by microorganisms, the surfactant is decomposed by microorganisms and eliminates the burden on the environment when the surfactant becomes unnecessary after the generation of micro-nano bubbles. be able to.

  Moreover, since the said nutrient contains nitrogen, phosphorus as a main component, and contains potassium, magnesium, and calcium, the said nutrient contains the nutrient required for various microorganisms, and is one factor of activation of microorganisms. It becomes.

In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  Specifically, when the micro-nano bubble generation aid and the fertilizer that is a plant nutrient as the nutrient are added to the microorganism-containing liquid, conventionally, a liquid fertilizer for a non-existing plant is formulated and prepared did it.

  And when the said liquid fertilizer is introduce | transduced into the hydroponic cultivation apparatus (not shown) as the said plant cultivation utilization process 16 and a plant is cultivated, it grows faster and grows a quality plant than conventional outdoor cultivation.

  Specifically, the effects of micro-nano bubbles have been confirmed in the aquaculture field, particularly in the cultivation of oysters, pearl oysters, and larvae.

  By activating the activated microorganisms into ginger in aquaculture, we were able to increase the production per unit time of the target aquaculture. Here, the target cultured products are eel, blue crab, flounder, black tiger, shrimp and the like.

  And it was effective in the aquaculture system which circulates and filters the breeding water in land culture. In addition, the frequency of exchanging rearing filtered water was reduced and the cost was reduced. The reason may be oxidation treatment of ammonia nitrogen and nitrite nitrogen in the breeding water by activation of ammonia oxidizing bacteria and nitrite oxidizing bacteria in the breeding filtration tank.

Note that in the sixth embodiment, the same portions as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  Then, when the microorganism-containing liquid is introduced into the chemical treatment utilization step 20, when the chemical treatment is neutral, the microorganism-containing liquid plays a catalytic role in the chemical treatment, and the efficiency of the treatment is improved.

Moreover, not only the improvement of processing efficiency but both physical processing and microbial processing can be expected.

  As a specific example, there is activated carbon adsorption which is a physical treatment, but when the above microorganism-containing liquid is introduced, activated carbon can microbially decompose not only the adsorption action but also the adsorbed components. That is, microorganisms activated on activated carbon propagate and activated microorganisms propagated on activated carbon decompose the adsorbed component adsorbed on activated carbon.
