Problems solved by technology

[0003] Dust reduction in urban storage yards can be achieved by sprinkling water. However, the dust reduction index by sprinkling water does not cure the root cause. There is also a green net with a small aperture to achieve the purpose of suppressing dust. However, this is not environmentally friendly and wastes resources, and the cost is relatively high. Economical, and the effect of suppressing dust is general

Abstract

The invention provides a construction process for urban storage yard dust control, comprising the following steps: (1) mixing bentonite, modifier, plant seeds, plant growth regulator and water to form dust liquid; (2) mixing 3 / 4 of the dust liquid The bottom film is formed by spraying the spray gun to the surface of the stockyard, the spray time is 8-10min, the spray distance is 4-5m, the spray pressure is 0.6-0.8MPa, and the spray flow rate is 1.5L / min; (3) on the bottom film surface Lay a layer of straw powder; (4) Spray 1 / 4 of the dusting liquid to the surface of the straw powder to form a cover film through the spray gun liquid. The spraying time is 3-5min, the spraying distance is 3-4m, and the spraying pressure is 0.5-0.6 MPa, the injection flow rate is 1.0L / min. The process is simple and low in cost, and large-scale construction can be realized. The construction process can achieve a good effect of controlling dust in urban storage yards, and is low in cost and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of greening and environmental protection engineering, and in particular relates to a construction technology for urban storage yard dust control. Background technique [0002] In recent years, with the deepening of my country's industrialization, dust pollution, especially in urban storage yards, has become more and more serious. The dust problem not only causes a large amount of resource loss, but also pollutes the surrounding environment, affecting people's normal production and life. With the strengthening of the meaning of environmental protection, people pay more and more attention to the control of dust pollution. [0003] Dust reduction in urban storage yards can be achieved by sprinkling water. However, the dust reduction index does not cure the root cause. There is also a green net with a small aperture to achieve the purpose of suppressing dust. However, this is not environmentally friendly and was...
