Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The amplitude of the pulsed electric field is 25 kv. The duty cycle of the pulsed electric field is 50%. The frequency of the pulsed electric field is 50 kHz. The rising edge and the falling edge of the pulse electric field are 5 kv/us. The action time of the electric field is 1 s.

EXAMPLE III
The positive and negative electric fields are opposite, as long as there is a potential difference between the two. As shown in fig. 1, the wind passes through a positive electric field, a negative electric field, a positive electric field, and a negative electric field in sequence. The reverse is also possible. Positive and negative charges are induced on the surface of the microorganism, when the field intensity of positive and negative charges is higher than 0.1V-50KV, charge transfer starts to occur when the macromolecular bond of the envelope on the surface is smaller than the induction field intensity, the molecular bond is broken, further the surface of the microorganism is torn, DNA and RNA are exposed, and chain DNA and RNA nucleic acid molecules are further broken under the action of a further electric field, so that the microorganism is killed. In the figure, a, b, c, d and e are the intervals of the electric field.
The invention has the working principle that a hierarchical electric field forms grid-shaped electric field distribution through the electric field, potential difference is formed between the hierarchical electric field and the grid-shaped electric field, when microorganisms such as bacteria, viruses and the like pass through the hierarchical electric field, strong potential difference enables the envelope or the surface of the microorganisms to induce corresponding potential, strong potential difference is formed on the envelope or the surface of the microorganisms, ion transfer is generated due to strong potential difference, the biomacromolecule bond of the envelope is separated, the envelope or the surface is torn, and DNA and RNA are exposed. In the subsequent grading electric field, the chain DNA and RNA will also be subjected to macromolecular bond removal under the action of the induction electric field according to the same technical principle, thereby resulting in incomplete DNA and RNA, loss of functions such as genetic replication and the like. Thereby killing microorganisms such as bacteria and viruses.
