As the static electricity voltage generation device for performing this static electricity induction process, a known static voltage generation device, for example, A densicharger manufactured by Electron Charger Laboratory Co., Ltd. and an electron charger manufactured by JEOL Ltd. can be used.

An example of the electrostatic voltage generator for carrying out the electrostatic induction process of the present invention will be described below by taking the densier charger type manufactured by Electron Charger Laboratory Co., Ltd. as an example. As shown in FIG. 1, reference numeral 1 is a transformer for generating an AC high voltage of a static voltage generator, which is an outer iron type circular winding type using a stratified iron core 2 The primary winding 3 of the side circuit is connected to an AC power source, one end 5a of the secondary winding 4 of the secondary side circuit of the transformer 1 is insulated, and the other end of the secondary winding 4 of the secondary side circuit is insulated. 5b, processing tank 6 installed separately
It is connected to the stainless steel electrode 7 provided inside. Further, the processing tank 6 is configured to be in an insulated state by an insulator 8 such as an insulator and a ground (earth) 9. However, a small electric circuit is formed between the ground 9 and the primary side circuit of the transformer 1 due to the leakage current.

As shown in FIG. 2, the transformer 1 has a tubular insulating film 10 fitted in the center of an iron core 2 and further has the above-mentioned primary winding 3 and secondary winding on the outer peripheral surface of the insulating film 10. Wrap with wire 4. As the primary winding 3, for example, a copper wire coated with polyester having a diameter of 0.6 mm is used to make 230 turns, and as the secondary winding 4, for example, a copper wire coated with enamel having a diameter of 0.09 mm is used. It is used 40,000 times, but 40,000 of this secondary winding 4
Among the windings, the first winding group 4a has 22,000 windings and the second winding group 4b has 18,000 windings. The diameter, type, number of turns, etc. of these copper wires are appropriately determined according to the type and breeding number of fish.

However, in the usual case, the diameter of these copper wires can be 0.03 to 3 mm, and the type of copper wire is not limited to the one coated with polyester or enamel, and is usually used as a copper wire. The number of turns of the copper wire may be 200 to 25 for the primary winding 3.
The number of turns is 0, the number of secondary windings 4 is 28000 to 40,000, and the first winding group 4 of the secondary windings 4 is
A may be 16800 to 22000 and the second winding group 4B may be 11200 to 18000.

Among the number of turns of the secondary winding 4, the number of turns of the second winding group 4b and the number of turns of the first winding group 4a are differentiated so that the second winding The outer diameter of the group 4B is made smaller than that of the first winding group 4A, that is, the second winding group 4A
The cap G2 between the iron core 2 and the second core is made 1.5 to 2 times larger than the cap G1 between the first winding group 4a and the iron core 2.

The other end 5b of the secondary winding 4, which is a lead wire on the outer peripheral surface of the first winding group 4a, is used as an output line for the processing tank 6
And the other end 5a of the secondary winding 4 which is a lead-out line on the outer peripheral surface of the second winding group 4B.
The insulating state is as described above.

One end 5a of the secondary winding 4 has one end of the secondary winding 4 which is obtained by winding an insulating tape around the tip of the secondary winding 4 and filling the transformer with an insulating material such as tar pitch. Insulation is performed by covering 5a, but insulating oil, unsaturated polyester resin, polyurethane resin or the like may be used as the insulating material in addition to tar pitch.

Polyethylene resin is preferably used for the material of the treatment tank 6, but any material other than polyethylene resin may be used as long as it is an insulating material and the eluate does not flow into the breeding water. it can.
Although the metal mesh cylindrical shape is most suitable for the stainless steel electrode 7, a slit shape, a perforated plate shape, or any other shape may be used in addition to this.

When an alternating current is applied to the transformer 1 to raise the primary voltage of the transformer 1 to 100 V, a voltage of about 12000 to 18000 V is generated on the secondary side of the transformer 1, but the secondary side is generated. The other end 5 of the second winding group 4B of the secondary winding 4 of the circuit
Since a is insulated, the stainless steel electrode in the processing tank 6 connected to the other end 5b of the secondary winding 4 which is a lead wire on the outer peripheral surface of the first winding group 4a of the secondary winding 4 About 7 to 350
A voltage of 0 to 4500 V produces a current of about 1.5 μA. That is, between the stainless steel electrode 7 inside the treatment tank 6 and the ground 9 outside the treatment tank 6, the breeding water that has flowed into the treatment tank 6 is electrostatically induced to generate an alternating current (AC) necessary for generating dielectric polarization (electronic polarization). Constitutes an electric field.

About 1200 generated on the secondary side in the transformer 1
The voltage of 0 to 18000 V becomes a voltage of about 3500 to 4500 V (current of about 1.5 μA) at the stainless steel electrode 7 in the processing tank 6 from the grounding 9 outside the processing tank 6 to the above-mentioned transformer 1. Primary winding of the primary side circuit 3,
After passing through the secondary winding 4 of the secondary side circuit of the transformer 1, the secondary winding 4
The other end 5b of the stainless electrode 7 in the processing tank 6
It is due to the AC resistance circuit formed by connecting to.

The voltage of the stainless steel electrode 7 in the processing tank 6 generated by the AC resistance circuit as described above is about 3500 to 4500 V, but the current is about 1.5.
Since it is as small as μA, it is safe for the human body and does not cause electric shock or fire.

The voltage and current generated in the stainless steel electrode 7 are appropriately changed by a voltage regulator (slidac) 11 provided on the AC power source side according to the treatment conditions of the breeding water to be treated. , Voltage 100-450
When the voltage is 0 V and the current is 0.5 to 1.5 μA, water molecules are electrostatically induced to form an AC electric field suitable for dielectric polarization and electronic polarization.

The stainless steel electrode 7 in the processing tank 6
In FIG. 4, when the stainless steel electrode 7 is positively charged, the negative charge is dielectricized to the ground 9, and when the stainless steel electrode 7 is negatively charged, the positive charge is dielectricized to the ground 9, as shown in FIG. Depending on the frequency of the AC power supply, the positive and negative charges of the stainless steel electrode 7 are exchanged for the frequency (50 to 60 times) per second, and accordingly, the charges of the ground 9 are also dielectricized and the positive and negative charges are changed. Will be replaced.

A general substance is composed of atoms, which are composed of atomic nuclei and electrons, and the atomic nuclei are composed of neutrons and protons. Then, in the steady state where an electron with a negative charge makes a circular motion around the nucleus and the electric field does not act from the outside, the positive charge of the proton and the negative charge of the electron are equal and stable. It is in a state.

However, when a high voltage is applied from the outside, the electrons move to one side and the protons move to the other side, so that the electric centers of gravity of the atoms do not coincide with each other, and the atoms have one electric dipole. Therefore, an internal electric field is generated due to the balance of charges and polarization is caused.

In this case, since atoms (molecules) are polarized by an external electric field, it is called electronic polarization or atomic polarization. All molecules contained in water have positively charged molecules moved to one side and negatively charged molecules. Molecule moves to the other. And
The movement of the molecules is switched 50 to 60 times per second according to the exchange of the positive charge and the negative charge due to the electrostatic induction described above, and this is repeated thereafter.

Water is introduced into the AC electric field generated in the stainless steel electrode 7 in the processing tank 6 to perform electrostatic induction treatment,
Due to the dielectric polarization and the electronic polarization based on the electrostatic induction, the water molecules flowing into the processing tank 6 and all the molecules in the water are rotated and vibrated to promote the separation and dispersion of the molecular population.

As a result of the above-mentioned electrostatic induction treatment, a state in which a positively charged hydrogen atom and a negatively charged oxygen atom are strongly attracted electrically to increase the intermolecular hydrogen bonding force. To activate and functionalize water. That is,
The amount of dissolved oxygen (DO) in the breeding water increases, organic matter, free and bound chlorine decrease, pH becomes weakly acidic, conductivity and redox potential increase, specific gravity, density, osmotic pressure increase,
The water becomes mellow, the solubility increases, and it becomes an environment where fish can easily survive and breed.

The conditions for the electrostatic induction treatment are appropriately determined according to the type of fish, the water quality of the breeding water, the voltage and the current of the stainless steel electrode 7, etc. In the normal case, the electrostatic induction treatment is continued during the breeding period of the fish. However, the electrostatic induction applied voltage is 100 to 4500.
V (electric field strength 0.3 to 12 KV / m), preferably 10
0 to 1500 V (electric field strength 0.3 to 3.8 KV / m),
A breeding temperature of 10 to 35 ° C is sufficient.
