Benefits of technology

This new technology uses tiny organism called bacteria that can fix CO2 from air or water without causing harmful side-effects like emissions such as sulfur oxides (SO2) or nitrogen compounds (NO). These processes involve capturing and converting them back into other materials through reactions between different substances. They also improve soil quality by adding more nutrients than what they were previously possible because these resources could be taken up quickly when needed. Overall this innovation provides technical benefits over existing technologies while reducing environmental impact caused by fossil fuel usage.

Problems solved by technology

This patented technical problem addressed by these inventors relates to improving the efficiency at reducing particulate matter (PM) emissions from industrial processes such as power plants or vehicles that use fossil fuels like coal, which can cause harmful environmental effects due to their combustible nature. Current ways involve adding chemical agents called antimicrobial mistging solutions, mechanically covered walls, welded plugs, and other techniques aimed towards controlling particle size reduction without affecting the overall function of the system being protected against PM emission. However, there are drawbacks associated with current approaches including excessive costs, complex operations, potential negative impact on health caused by reactive materials used during manufacturing, and poor ecocompatibility issues related to long term exposure to harsh environments.

Abstract

The invention discloses a microbial dust suppressant and its application. The microbial dust suppressant consists of 2.0wt%-3.0wt% of microbial powder, 29.0wt%-30.0wt% of calcium source and 67.0wt%-69.0wt% of ionized water Composition, described microorganism is bacillus lysinus, and described calcium source is calcium chloride. The microbial dust suppressant is evenly sprayed on the sandy soil surface under the condition of the ambient temperature of 2°C≤T≤20°C, uses microorganisms to capture carbon dioxide in the environment and converts it into carbonate, and reacts with an external calcium source to form a gelling effect The carbonate minerals have successfully consolidated loose sand particles into a whole and have certain mechanical properties. Compared with traditional methods, this method has significant dust suppression effect, low cost, convenient construction, no secondary pollution, and good ecological compatibility.
