Summary. The normal data range for dust monitoring depends on the detection accuracy of the monitoring equipment and the air quality standards of the area. In general, China's national environmental protection standards require that the 24-hour average concentration should not exceed 75 micrograms of cubic meters, and that the concentration of particulate matter in a single hour should not exceed 150 micrograms of cubic meters.

The U.S. Environmental Protection Agency's national air quality standards are more stringent, requiring a 24-hour average concentration of no more than 35 micrograms of cubic meters and an annual average of no more than 12 micrograms of cubic meters. Therefore, the normal values for dust monitoring must be lower than the specified standards, which will vary from place to place.

The normal data range of the dust monitoring group depends on the detection accuracy of the monitoring equipment and the air quality standards of the area. In general, China's national environmental protection standards require that the 24-hour average concentration should not exceed 75 micrograms of cubic meters, and that the concentration of particulate matter in a single hour should not exceed 150 micrograms of cubic meters. The national air quality standards of the United States or the National Environmental Protection Agency are more stringent, requiring an average concentration of no more than 35 micrograms for 24 hours and no more than 12 micrograms for an annual concentration.

Therefore, the normal values for dust monitoring must be lower than the specified standards, which will vary from place to place.

Can you elaborate on that a little bit more?

The function of the dust monitoring equipment is to monitor the dust particle concentration data and noise data in the construction site environment. It is an important monitoring equipment in the construction environment, which greatly facilitates the management and supervision of the construction unit by the environmental protection department.

You can view the environmental status of each construction unit through the data platform, and use this as the data basis to conduct relevant investigations and visits to the construction site in real time, and urge the construction site to rectify the construction equipment and construction environment in a timely manner and in accordance with the law. A few days ago, the Xi'an environmental protection department conducted statistics on all construction sites within the city's construction area and found that the concentration of particulate matter was high, which seriously affected the atmospheric environment around the construction site. Therefore, the situation is not optimistic.

At the same time, the noise interference situation is also serious, and many residents are miserable. However, surveys are time-consuming and laborious, and collecting and collating data is difficult. To this end, the Xi'an environmental management department implements the guidelines and policies for the installation of dust monitoring equipment at the construction site in accordance with the relevant laws and regulations on environmental protection management.

The noise data is uploaded to the environmental protection platform to manage and supervise the construction site environment in a unified manner.

Fugitive Dust Monitoring Equipment, Monitoring Noise, Requires the Use of Noise Sensors and Noise Monitoring Accessories. Noise sensors are used to receive sound waves and display the vibration image of the sound. Through the acoustic-sensitive condenser electret microphone, the sound wave causes the electret film inside the microphone to vibrate, causing the capacitance to change, and generating a small voltage corresponding to the change, so as to realize the conversion signal from optical signal to electrical signal.

The noise monitoring accessories measure the decibel range of 30-130db, which can be monitored in real time 24 hours a day. At a minimum, most instruments used for environmental noise monitoring should have a time-averaged integration function, i.e., at least the equivalent continuous sound level LEQ value can be measured to meet the data monitoring requirements of environmental regulatory authorities. However, for environmental monitoring stations that need to carry out traffic noise measurement or noise survey, they should also have statistical sound level ln(n) measurement and 24-hour monitoring functions.

At the same time, they also absorb light. Part of the energy that irradiates light. According to the relative attenuation rate of incident light passing through the measured concentration field, the relative attenuation rate can basically reflect the relative concentration of dust in the measured field linearly.

Then the magnitude of the light intensity is proportional to the intensity of the electrical signal converted by photoelectric conversion, and the relative attenuation rate can be obtained by measuring the electrical signal, and then the dust concentration in the field to be measured can be measured.

At present, more and more construction units are looking for and consulting through different channels to sell and operate dust monitoring equipment and manufacturers to purchase equipment, but to find high-quality and powerful manufacturers, the purchase of preferential and cost-effective equipment, or some efforts.
