A multifunctional compound fugitive dust inhibitor based on active enzyme preparation

Abstract

The invention discloses a multifunctional compounded flying dust suppressant prepared on the basis of an active enzyme. The multifunctional compounded flying dust suppressant is prepared from the following raw materials in percentage by weight: 0.28-0.32% of bioactive enzyme, 0.07-0.12% of high-polymer water-absorbing resin, 4.50-5.00% of CO(NH2)2, 4.40-4.50% of CaCl2, 2.20-2.30% of CaO and the balance of water. The bioactive enzyme is urease which is an artificially extracted plant enzyme. The application method of the dust suppressant comprises the following steps: dissolving powder materials in water according to the percentage by weight, uniformly mixing, spraying the mixture on the road surface and stockpile surface, wherein the amount of the mixture is 1-3L for every 1m<2> of the municipal road, and the amount of the mixture is 3-6L for every 1m<2> of the stockpile. By utilizing the principles of moisture absorption, moisture retention, bonding, biodegradation and biological calcification, the dust suppressant effectively enhances the flying dust suppression effect, and has the advantages of long acting duration time, lower secondary flying dust, high reaction speed, high temperature resistance and environment friendliness.

Description

technical field [0001] The invention belongs to the fields of environmental protection and engineering construction, and relates to a dust suppressant. Background technique [0002] It is difficult to avoid floating soil and dust at the construction site. Due to factors such as wind force and vehicle traffic, the surrounding dust pollution is relatively serious, endangering the health of residents and workers, affecting the growth of animals and plants around the construction area, destroying the ecological balance, and causing extremely bad social impact. It causes great economic losses to the country and enterprises. According to the environmental impact assessment reports and environmental protection completion acceptance reports of various road constructions, the dust pollution at the road construction site is relatively serious, among which the total suspended particulate matter (TSP, also known as total suspended particulate matter) at 100m away from the concrete mixin...

AI Technical Summary

Problems solved by technology

However, there are certain defects and deficiencies in all kinds of dust suppressants. Moisture absorbents and dust sticky agents have limited dust suppression effects and have an impact on the use of roads. Moisture absorbents represented by high-molecular organic matter, due to the lack of certain bonding It is easy to be attached and taken away by vehicles, which will affect the use effect

[0007] At the same time, the existing wetting agents, solid / liquid hygroscopic agents, sticky dust agents, and composite dust suppressants are likely to cause environmental deterioration and pollution because they cannot be naturally degraded in the environment
