Dust suppressing agent prepared on basis of microorganisms and use method thereof

Abstract

The invention discloses a dust suppressing agent prepared on the basis of microorganisms and a use method thereof. The microorganism dust suppressing agent is prepared by mixing a bacterium solution and a calcium-ion solution by proper matching ratio. The use method of the dust suppressing agent comprises the following steps: the dust suppressing agent is uniformly sprayed on the surfaces of raise dusts; according to the actual need, the used amount of the dust suppressing agent for treating the raise dusts with the stacking volume being 1m<3> is 300-400L, and the 1-3 treating times are carried out according to the effect need. The dust suppressing agent has the advantages that the dust suppressing effect is obvious, the evaporative resistance, the wind-erosion resistance and the durability are respectively and greatly superior to those of the sprinkling mode for suppressing dusts when in raise-dust treatment, the greenhouse gas CO2 is absorbed in the reaction process, no toxic and harmful substance is generated, and the environmental friendliness and the economy are good.

Description

technical field [0001] The invention belongs to the interdisciplinary science and technology in the fields of microbiology and environmental protection, and relates to the preparation and application method of a novel microbial dust suppressant. Background technique [0002] In recent years, smog has swept across the land of the motherland, and PM2.5 has seriously threatened the health of the people. According to the survey, with the increasing traffic infrastructure, construction engineering activities are becoming more and more complex, and industrial activities are becoming more and more frequent, production activities such as transportation, construction and industry will inevitably produce dust pollution, especially construction dust, because it is produced in the city, serious It affects the urban ecological environment and endangers the physical and mental health of residents. [0003] At present, water sprinkling is mainly used to suppress dust at the construction s...

AI Technical Summary

Problems solved by technology

[0003] At present, water sprinkling is mainly used to suppress dust at the construction site, but water sprinkling can only wet the surface of the dust, and it is difficult to penetrate into the interior. Because the water on the surface of the dust evaporates quickly, the dust suppression time of water sprinkling is short, the dust suppression effect is poor, and the dust is raised after the water evaporates. Once again in an unrestricted state, it migrates around with the wind, which is not conducive to cleaning

[0004] Nowadays, many different types of dust suppressants have been developed in countries all over the world, but due to the complicated processing and spraying process, high cost, poor environmental compatibility and other reasons, few of them have been actually promoted and applied.
