Method for killing bacteria in microalgae by using electromagnetic pulse

Abstract

The invention discloses a method for killing bacteria in microalgae by using electromagnetic pulse. Square-wave pulse is performed on a microalgae solution, and the beam of the square-wave pulse is aligned to the part of the microalgae solution containing bacteria; the beam of the square-wave pulse is controlled, so that the focused beam moves on the microalgae solution containing bacteria, and microalgae are prepared. The method has a good sterilization effect, is simple to operate and convenient to use and has sterilizing and mildew killing functions.

Description

technical field [0001] The invention relates to the technical field of algae cultivation, in particular to a method for killing bacteria in microalgae by electromagnetic pulses. Background technique [0002] EMP~(electromagnetic pulses) Electromagnetic pulses are produced by nuclear explosions and non-nuclear electromagnetic pulse bombs (high-power microwave bombs) explosions. The electromagnetic pulse generated by a nuclear explosion is called a nuclear electromagnetic pulse. Any nuclear weapon that explodes above the ground will generate an electromagnetic pulse. Non-nuclear electromagnetic pulse bombs use the energy generated by explosive explosion or chemical fuel combustion to convert it into high-power microwave radiation energy through microwave devices, and can emit pulsed microwave beams with a peak power of more than several megawatts and a frequency of 1 GHz to 300 GHz , A transient voltage of thousands of volts is generated sharply on exposed conductors (such as...

Problems solved by technology

[0004] In related technologies, a common way to kill bacteria is to apply some chemical bactericidal drugs on the parts containing bacteria; because bacteria often exist in the form of colonies, and each colony contains many different bacteria, therefore, when using chemical sterilization When the drug kills bacteria, it is necessary to smear corresponding chemical bactericidal drugs for different bacteria; however, when using chemical bactericidal drugs, there may be multiple bacteria in the form of colonies on the same site, so the smeared chemical bactericidal drugs often Overlap each other, and then cause the chemical bactericidal drugs to not be able to effectively directly contact the bacteria they can kill, so the bactericidal effect is not ideal

[0005] In terms of fluid use safety (such as water safety), when surface water bodies are generally polluted, water sources are prone to breed bloodworms, bacteria, algae and other substances, which have a serious impact on water quality safety.

Traditional methods usually use chemical oxidants for water treatment, but there are the following disadvantages: First, chemicals such as scale inhibitors, corrosion inhibitors, and fungicides increase the disinfection by-products in the effluent, such as trihalogenated methane, haloacetic acid, etc. 1. The content of mutagenic substances has affected the safety of drinking water; second, this method cannot 100% kill bloodworms (the intermediate host of pathogenic organisms in water, an important medium for spreading diseases), and the effective rate is low; in addition, the method The method cannot effectively treat various substances such as red worms, bacteria, algae, and organic matter at the same time
