The effect of electric fields on biological body and application thereof:
(A) effect of electricity to large-scale higher organism
When certain electric current is by human body, frequency disturbance effect caused by the alternating-current of the heat effect, magnetoresistive effect and the certain frequency that produce in human body due to electric current, the tissue of human body can be made particularly to burn by damage to a certain extent, the damage of tissue unrepairable time serious, can be caused even dead.It is generally acknowledged that the safety voltage that human body can bear is 36V in China, when human body be subject to >=the voltage effect of 36V time, will injury from electricity be subject to.
The simple device for fishing and hunting such as electric fish device, electric hare device is also there is among the people.When the output voltage of electric fish device is at 500 ~ 1200V, output rating, when more than 150W, can damage the neural system of the fish in distance electrode about 1.5m scope in water, make fish faint and float on the water surface, and then reach the object of fishing.
In addition, the self-defence stun-gun that commercially can buy, thunder and lightning casualty accident often can heard etc., all shows that electric field has very large injury from electricity effect to large-scale higher organism.

The effect of electric field to unicellular microorganism is the hot issue studied in recent years, especially uses pulsed electric field to carry out sterilizing to food in field of food industry.
Use high-voltage pulse electric field sterilization, mainly apply the structure of very high voltage damages cytolemma, cell is caused to the some electrical breakdown of unrepairable.The destruction of unrepairable to be caused in theory to cell, the strength of electric field of 1 × 106V/cm be had.Research shows, the strength of electric field>=20kV/cm of energy effective sterilizing, the distance between electrode is grade, the volume <50cm of discharge process room
3.
As adopted the strength of electric field needed for sterilizing to process former water, all living things body that in theory can be existing in Inactivation in Water, but due to its discharge process room volume little, be difficult to be applied in the production practice of water factory.On the other hand, 0.5 ~ 1 (kWh) m is about for the energy consumption needed for sterilizing
3, being applied to water factory can increase cost of harnessing the river greatly, therefore less feasible.
(C) principal feature of invertebrates and electricity are to its effect:
Overwhelming majority water factory of China take surface water as water source, and in former water, invertebrates kind and quantity are enriched, and dwell type chironomus larvas, nematode etc. at the existing end, also has zooplankton rotifer, cladocera, copepods.These invertebratess both had complete tissue and neural system unlike large-scale higher animal, also unicellular microorganism is different from such, it has simple weave construction, and enable the effective deactivation invertebrates of electric field if therefore inferred, then required strength of electric field will fall between.
And about electric field to the concrete mechanism of action of invertebrates and action effect not too many report and research, the present invention has done a simple proof test to probe into the action effect of electric field to invertebrates common in water.With a simple circuit, connect the alternating-current of 220V, 50HZ, be energized in the water that the red line worm having vital activity very strong exists, observe electric field to the effect of red line worm, tentatively determine the deactivation characteristic of electric field to invertebrates, process of the test is: in process of the test, and two electrodes are placed directly in water observes the vital activity of red line worm when being subject to electric field action.Test-results shows, under the effect of the alternating-current of 220V, 50HZ, red line worm just loses activity in a short period of time, and loss of life activity sign illustrates that electric field has effectively deactivation to invertebrates.
