Urban soil dust control construction technology

Abstract

The invention provides an urban soil dust control construction technology, belonging to the technical field of environmental protection engineering. The urban soil dust control construction technology comprises the following steps: (1) clearing an urban soil surface to remove debris on the urban soil surface; (2) uniformly mixing straw subjected to solid-state fermentation, starch grafted acrylate, a plant growth regulator, ammonium dihydrogen phosphate, plant seeds and water to obtain a dusty liquid; (3) spraying the dusty liquid to the urban soil surface by utilizing a rotor type sprayer, with a distance between a muzzle and soil of 1.5-2.5 m, a spraying pressure of 0.12-0.15 MPa, and a spraying flow of 1.2-1.7 L / min. The urban soil dust control construction technology is easy, can achieve large-scale construction and a good effect on control of urban soil dust, becomes effective quickly, 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 technique for urban soil dust control. Background technique

[0002] Particle pollution has a wide range of influences on the air quality of cities in my country, and is the primary factor of air pollution in most cities. Particle pollution endangers the environment and human health and has become a world pollution problem. Flying dust is the main factor causing urban particle pollution. With the deepening of my country's industrialization, the problem of dust pollution is becoming 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.

[0003] Urban dust can be suppressed by sprinkling water, or by covering green nets with small apertures to suppress dust. Among them, watering and dust...
