What is the best way to control dust pollution in construction sites?

Dust control measures in building construction;

With the rapid development of urban construction, the number of construction sites around the country has increased rapidly, and the dust generated in all aspects of site construction has become an important factor leading to air pollution. With the deepening of the blue sky defense war, strengthening the prevention and control of dust pollution in construction sites has become an important task of urban environmental governance.

In view of some difficulties encountered by the regulatory authorities in the prevention and control of dust on construction sites, five suggestions are shared, hoping to improve dust pollution on construction sites.

Construction site supervision departments should, in combination with daily education, explain the measures and standards for dust prevention and control in construction sites to enterprises, inform relevant responsible subjects of the basis and amount of administrative punishment they will receive in violation of relevant regulations on dust prevention and control, and guide them to consciously perform their responsibilities for dust prevention and control.

Construction site supervision departments should strictly take the construction enclosure, hardening of main roads, cleaning facilities, enclosure spraying, whether to install monitoring networking as required, whether to install license plate recognition and road gate facilities, and whether to have preventive plans and special preventive funds as preconditions for approving construction permits. If the hardware facilities for dust prevention and control fail to meet the requirements, they shall not be examined and approved, and construction shall not start.

Construction sites and construction, construction and supervision units that fail to prevent and control dust pollution should be strictly managed and severely punished. Those who fail to make rectification according to the requirements or fail to make rectification within the time limit shall be ordered to stop work for rectification according to law, and their bad behaviors shall be included in the credit management system for muck disposal in accordance with relevant regulations. If the circumstances are serious, it shall be investigated and dealt with by informed criticism, and exposed through the media, linked to market access, appraising awards, qualification promotion, bidding, etc.

The prevention and control of dust in construction sites involves not only different supervision departments, but also construction units, construction units and supervision units. In order to improve the prevention and control effect of dust pollution in construction sites, it is necessary to clarify the regulatory responsibility and territorial management responsibility of construction, municipal, transportation, construction headquarters and other departments in the prevention and control of dust pollution in construction sites in accordance with the principle of "who is in charge, who is in charge of examination and approval, and who is in charge of pollution prevention and control", and strive to realize that all departments perform their duties and cooperate with each other.

Build a comprehensive supervision service platform for muck transportation and disposal, which is connected with the site monitoring system to monitor whether the vehicles entering and leaving the site are regular, whether the vehicles entering and leaving the site are washed, whether the dust data of the site exceeds the standard, whether the excavation volume in the site exceeds the declaration, whether the facilities in the site are in good condition, and whether the site is neatly stacked. And through the statistical analysis of big data, rationally plan transportation routes and disposal sites.

The law enforcement vehicle is equipped with vehicle-mounted mobile dust monitoring equipment, which can acquire the data of seven elements such as PM2.5, PM 10, noise, temperature, humidity, wind direction and wind speed in real time, and collect and transmit live video in real time. All data are sent to the server in the dust data center for analysis and storage in real time through the wireless communication module.
