Environment-friendly synthesis method of biological dust suppressant

Abstract

The invention provides an environment-friendly synthesis method of a biological dust suppressant. The environment-friendly synthesis method of the biological dust suppressant comprises the steps of activation culture, culture expansion cultivation and culture fermentation cultivation; the principle is that working bacterial strains in a dormant state are awakened through the activation culture, working bacteria with absolutely superior number are obtained through the culture expansion cultivation, the working bacteria are enabled to take a fermented Landy culture medium as a medium through theculture fermentation cultivation, and surfactin with excellent surface activity and wettability is synthesized by secondary metabolism. According to the environment-friendly synthesis method of the biological dust suppressant, no extreme condition tolerance requirement is required for a synthesis device, the synthesis method is simple, the synthesized surfactin can significantly reduce the contact angle of a dust suppressant solution and dust at a very low concentration, the ability of wetting the dust is fully improved, the characteristics of green environmental protection and environmentalfriendliness are achieved, and wide applicability in the field of productive dust prevention and control is achieved.

Description

technical field [0001] The invention relates to a synthesis method of a dust suppressant, in particular to a green synthesis method of a biological dust suppressant, which utilizes biological means to synthesize surfactant as a dust suppressant, and belongs to the new technical field of biological dust suppression. Background technique [0002] Dust suppressant (surfactant) anti-dust technology has broad application prospects in industrial fields such as environmental protection, mining, chemical industry, metallurgy, construction, and agricultural field. For example: Adding a certain amount of surfactant to clean water can significantly reduce the surface tension of water, improve the dust-reducing performance of the water medium, make it more fully infiltrate solids or wet floating dust, and inhibit the generation of dust or capture floating dust. However, the existing dust suppressants are generally chemical dust suppressants, which are used at a higher concentration, res...

AI Technical Summary

Problems solved by technology

However, the output of the existing surfactant preparation technology is low, and it is difficult to popularize and use it in the field of industrial and agricultural production dust control

With the advancement of surfactin synthesis technology, some scholars have tried to increase the yield of surfactin by means of genetic engineering and other methods, but the effect of this method on increasing surfactin production will tend to weaken with the increase in the number of passages, and cannot meet the requirements for stable production of surfactin , and increases the complexity of the process, resulting in increased production costs
