[ Focus on Chemical Machinery and Equipment Network ] According to reports, the pollution process in Beijing-Tianjin-Hebei and surrounding areas began on the 14th, mainly in the central and southern parts of the Beijing-Tianjin-Hebei region and the central and western parts of Henan.
Beijing may reach moderate pollution.
There is a risk of serious pollution.
Since the previous period is now the heating period, emissions have also increased.
At this time, the central and southern parts of Beijing-Tianjin-Hebei will (form) moderate to heavy pollution, especially in cities such as Shijiazhuang, which may be at risk of serious pollution.
Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipmentBeijing may reach moderate pollution.
There is a risk of serious pollution.

At this time, the central and southern parts of Beijing-Tianjin-Hebei will (form) moderate to heavy pollution, especially in cities such as Shijiazhuang, which may be at risk of serious pollution.
In addition, the editor learned that experts predict that this round of pollution will gradually end with regional precipitation.
From the night of the 17th to the whole day of the 18th, a systematic precipitation process affects North my country from west to east.
The precipitation time is longer and the amount of rainfall is large.
The pollution situation will be significantly alleviated.
It is expected that the night of the 18th will be mainly good to light pollution.
.
From the 19th to the 20th, the regional diffusion conditions were significantly improved, and the pollution process was completely ended.
With the new round of pollution in the Beijing-Tianjin-Hebei region, environmental monitoring equipment is indispensable.

With the new round of pollution in the Beijing-Tianjin-Hebei region, environmental monitoring equipment is indispensable.
With the development of industry and science, the content of environmental monitoring has gradually developed from the monitoring of industrial pollution sources to the monitoring of the general environment.
That is, the monitoring objects are not only the pollution factors that affect the environmental quality, but also the monitoring of biological and ecological changes.
The monitoring of environmental pollutants is often not only the determination of its composition and content, but also the monitoring of the form, structure and distribution law.
Physical pollution factors (such as noise, vibration, heat, light, electromagnetic radiation and radioactivity, etc.
) and biological pollution factors should also be monitored.
Only in this way can we fully and accurately explain the extent of the impact of environmental pollution on the survival of people and organisms and the ecological balance, so as to make a correct environmental quality assessment.
The purpose of environmental monitoring is to accurately, timely and comprehensively reflect the status and development trend of environmental quality, and provide scientific basis for environmental management, pollution source control, environmental planning, etc.

In the 1950s, the early environmental monitoring mainly used analytical chemistry methods to analyze pollutants.
However, due to the low content of environmental pollutants (usually at the ppm or ppb level) and rapid changes, it was actually the development of analytical chemistry.
Pollution source monitoring stage.
Since the 1960s, people have gradually realized that environmental pollution includes not only the pollution of chemical substances, but also noise pollution; it includes not only the monitoring of pollution sources, but also the monitoring of environmental background values.
The scope of environmental monitoring has expanded and more methods are used.
This stage is called For environmental monitoring stage.
In the 1970s, environmental monitoring technology has entered automation and computerization, and developed countries have successively established national automated monitoring networks.
This stage is called the automatic monitoring stage.

To monitor the environment, instruments and meters are indispensable , such as ambient air ground automatic monitoring equipment for daily air quality monitoring, motor vehicle exhaust monitors, pollution source smoke (dust) monitors, and so on.
Instrumentation The air quality monitor can provide accurate and real-time monitoring, evaluation, and analysis of air pollution, helping users grasp the environmental air quality status in the area, discover the pollution characteristics, and provide technical support for the prevention and control of air pollution.
The significance of the application of the air quality monitor is to scientifically monitor the environment from a microscopic perspective, and then obtain scientific data about environmental quality, so as to conduct scientific and accurate analysis of environmental quality, and carry out timely development and treatment of pollutants, and then Effectively prevent and treat environmental pollution, ensure the safety of people’s lives and property in the country, and avoid unnecessary losses to the people due to atmospheric pollution.
Pollution source smoke (dust) online monitor is used for online monitoring of pollution source smoke and process dust emissions (concentration or total), including measuring related parameters: flow, O2, moisture content, temperature, etc.
, to achieve total pollution source emissions monitoring Required monitoring equipment .
In addition, the pollution source online monitoring instrument is to continuously monitor the total amount of pollutant discharge, the required concentration and the flow rate.
Online flow measurement and proportional sampling are the basic technical means for total amount monitoring.
For key pollution sources, online monitoring instruments are also required.
