Description

[0001]
[Industrial application fields]
The present invention instantly introduces plankton and mixed organism larvae for the purpose of providing detoxification to prevent damage caused by soil pollution of global freshwater, seawater plankton and contaminated organism larvae that destroy ecosystems. It is related with the method characterized by killing.
[0002]
[Conventional technology]
Although freshwater aquatic and seawater aoko are the same species, they can inhabit both freshwater and seawater, but they are very difficult to die, and damage to reservoirs and dams as drinking water continues. Similarly, red tide plankton, Hetrocabusa, Alexandrium, Tamalense, etc. that poison bivalves in sea surface culture in recent years is a big threat because oysters, clams, etc. are poisoned when they produce toxic saxitoxins. This is due to the increase of suspended pollutants and sludge formation of sediments due to their subsidence, and drought nutrition due to the inflow of nitrogen and phosphorus. Since these plankton and mixed organism larvae grow on the intake system, they were difficult to remove and expected to prevent contamination without destroying the environment.
[0003]
The deposits on power plant heat exchanger pipes, aquarium water supply pipes, etc., have been put into practice by preventing the injection of chemical substances such as copper ions and chlorine. Despite the danger, the effect is not certain.
[0004]
Red tide plankton and contaminated organisms in seawater are mixed in when loading seawater in the Japan Sea as a heavy oil tanker for crude oil imported by Japan from oil producing countries. Since it is drained into the sea area, a large amount of red tide plankton and mixed organisms from Japan are supplied to the sea area. For this reason, there is a worldwide demand for complete detoxification and detoxification in oil tank ships. The blue mussel has spread all over the world from the Mediterranean, and as a similar case, it has been mediated by ships and moved, so the world is in trouble, but there is no fundamental countermeasure.
[0005]
[Problems to be solved by the invention]
According to the present invention, the fresh water and seawater described in claim 1 can be rendered harmless when taking water, and in order to eradicate damage caused by plankton in water and larvae of mixed organisms, It is an object of the present invention to provide a new complete killing technology method using an electric shock for non-polluting cell membrane destruction without producing a product.
[0006]
In order to render the tank water according to claim 2 harmless, a method of a technique for providing a plurality of electrode pairs in the tank and completely killing plankton and mixed organism larvae even during use or storage of the tank water is provided. With the goal.
[0007]
By providing an electrode pair in the water pump according to claim 3, it is possible to safely use it as a detoxification even in a place where the complete killing device according to the present invention is not yet provided. In addition, the purpose is to provide a method of technology that completely kills plankton such as blue sea urchins and mixed organism larvae so that safe water can be supplied to clean water plants, condominium water tanks, etc. as clean water in advance. .
[0008]
[Means for solving problems]
In order to achieve the above object, an electrode pair is provided in the intake passage according to claim 1 of the present invention, and an electric field is applied by applying voltage and current from 1,2 volts 0,7 amperes to 6 volts 2 amperes to the electrode pairs. A method characterized by instantaneously killing plankton and contaminated organism larvae by destroying cell membranes regardless of the effect of by-product chlorine. If these plankton and mixed organism larvae are not killed by halfway attack, they will surely proliferate and counterattack and cause great damage, so the cell membrane should be destroyed and killed completely. . It is possible to install a pair of electrodes in the water intake passage and break the cell membrane with an electric shock at an economically low cost, and since the running cost is very low with a small number of Watts, it can be put into practical use without causing pollution. To overcome this problem, it was overcome by the following conditions.
[0009]
(1) It is known that a cell can be killed by applying a minute electric potential to the cell by an electron transfer reaction. Seawater is an electrolyte, but plankton and contaminated larvae were killed by extremely low currents and voltages that did not produce chlorine as a by-product.
(2) Plankton as microorganisms and mixed organism larvae are usually 0, 1 to several tens of microns and are not killed in contact with the wire mesh electrode, but the cell membrane is destroyed when passing through a 1 mm thick electric field. Adopted the method of killing. The enormous electrode pair surface area and quantity required for the method of contact and killing is unnecessary. In the case of being killed by contact, if the electrode mesh is made small, there is a problem that clogging occurs.
(3) There was no incidental work such as cost, space, extension of extension period, etc. for expanding the capacity of the existing power generation engine as a power source. Since the cells were killed by applying a very small potential of 1 to 6 volts to the cells, there was no need for these large-scale incidental works, and there was no need to change the power supply plan because of the increase in power equivalent to that of lighting fixtures.
(4) Plankton and mixed organisms larvae cannot proliferate unless they are rich in nutrients in the environment. However, due to the rise in seawater temperature due to global warming and the inflow of domestic wastewater into the sea due to increased living standards, Because it has abundant, it has become possible to multiply anywhere without choosing the sea area. Blue sea bream and the like can be inhabited without distinction between fresh water and sea water, so that they can be freely grown in a fresh water tank, and can be instantly killed by the effect of the present invention without producing by-product chlorine.
(5) Due to the accumulation of shellfish poison plankton in bivalves, sales of cultured oysters have been suspended. These shellfish poison plankton are, for example, Alexandrium. Tamalense swims with flagella. The swimming stopped instantaneously due to the application of a slight electric potential from 1 to 2 volts to disassembled garbage. Since the venom was also decomposed by bacteria, there were no obstacles in the sea area.
[0010]
In order to achieve the above-mentioned object, in order to make the tank water harmless according to claim 2 of the present invention, a method of providing a plurality of electrode pairs in the tank and killing plankton and mixed organism larvae, except for the intake passage, Provided a means to solve the problem by seeking double safety. Even if it flows into the tank from an untreated circuit for some reason, the killing effect continued in the tank by the method of the present invention. The convection effect due to the generation of hydrogen gas from the cathode side of the electrode pair was also observed.
[0011]
The pump according to claim 3 of the present invention is provided with an electrode pair to completely kill plankton and mixed organism larvae so that they can be supplied to other places, and water is also sent to places where the killing apparatus is not yet used. I was able to do that. It can be used freely by connecting pipes. This has the advantage that it can be used automatically by the circulation method without increasing the capacity extremely.
[0012]
[Action]
The method for killing plankton and mixed organism larvae according to claim 1 of the present invention has the following effects. Plankton and contaminated organism larvae die when the cell membrane is destroyed. As a method of electrical sterilization, a high-pressure pulse electric field is applied, and a substance with a bactericidal action such as hydrogen peroxide and chlorine is generated by an AC power source. There is. On the other hand, there is a cell-electrode electron transfer reaction that uses a new electroshock method that does not cause decomposition of seawater and fresh water by applying a low electric potential of 0,74 volts, which does not cause decomposition of seawater and fresh water. is there. In this method in which a cell is killed by applying a plus potential to the minus potential of the cell, the hydration of its own negative charge is destroyed, the cell membrane is broken and peeled off, and it is killed and decolorized and transparentized and decomposed instantaneously.
[0013]
In addition, when the sea urchin paste diatoms are killed, the cell membrane is decolored and transparent when observed with a microscope at a magnification of 200, and it becomes apparent one after another that the cells of the ground paste are not visible. The cell membrane peels off and becomes decolorized and transparent and dies. Planktonic diatoms such as Rhizosolenia and Eucampia were also killed by the method of the present invention. Similarly, flavobacterium can be inhabited in both freshwater and seawater, but could be instantly killed.
[0014]
In the method for killing plankton and mixed organism larvae according to claim 2 of the present invention, since a plurality of electrode pairs are provided in the tank, water circulation occurs while using rolling and pitching as ship hulls in the ship and passes through the electrode pairs. Therefore, it is possible to kill plankton and mixed organism larvae, but such convection does not occur in onshore tanks, but when multiple electrode pairs of the present invention are provided, water circulation occurs due to the rising flow of hydrogen gas on the cathode side The effect to do was seen.
[0015]
In the method for killing plankton and mixed organism larvae according to claim 3 of the present invention, since the electrode pair is provided in the pump, the seawater passing through the pump can instantaneously kill the plankton and mixed organism larvae. For this reason, it is not necessary to install an electrode pair as a killing device in a place other than the pump. The feature of killing plankton and mixed organisms larvae at the moment of passing through the pump is utilized.
